The sensitivity of a thick blood film is 5-10 parasites/µl. 6. calculate the parasitemia after giemsa staining. Giemsa staining was used for the first two sporozoite challenge studies, and Field's stain in coplin jars for the later two studies. Delay in preparation of smears can result in changes in parasite morphology and staining characteristics. CHAPTER THREE. A properly stained slide is critical in identifying malaria parasites. This very useful article, prepared by a well-known authority and based on his many years of experience, gives a very practical account of staining techniques for malaria parasites. The incidence of malaria 3.4 Preparation of Blood Film Preparation of buffer Solution to be used with. Romanowsky Stains are the stains that are used in hematology and cytological studies, to differentiate cells in microscopic examinations of blood and bone marrow samples. GIEMSA STAINING OF MALARIA BLOOD FILMS MALARIA MICROSCOPY STANDARD OPERATING PROCEDURE – MM-SOP-07A 1. malaria, illustrates that evaluation of Giemsa – stained peripheral blood smears is still the gold standard in the laboratory diagnosis of malaria, and emphasizes the importance for clinical laboratory scientists to maintain maximum competency in peripheral blood smear evaluation for bloodborne parasites. EQUIPMENT Staining tray, constructed so that the slides maybe stained face downwardsin a smallvol- Which of the following would describe the appearance of this parasite in this stain? Thick and thin blood films were examined from ten patients with P. knowlesi, with a parasitaemia between 610 to 236,000 parasites per μl blood (Table 1).All of the developmental stages of the malaria parasite life cycle expected in the peripheral blood were observed in Giemsa-stained … Giemsa stain is also used to visualize chromosomes.This is particularly relevant for detection of Cytomegalovirus infection, where the classical finding would be an "owl-eye" viral inclusion.. Giemsa stains the fungus Histoplasma, Chlamydia bacteria, and can be used to identify mast cells.. Generation. Giemsa stain is used in cytogenetics and for the histopathological diagnosis of malaria and other parasites. Place slides into the working Giemsa stain (2.5%) for 45-60 minutes. It is purchased ready to use or is made up at regional centers by skilled technicians and then distributed throughout the laboratory and malaria control programmer network. Figure 1 shows blood sample with the presence of malaria parasites in blood cell. Figures 2-5 are modified from: Βench aids for the diagnosis of malaria, WHO, 1988. Plasmodium falciparum . If one test is negative and no parasites are found, you will have repeated blood smears every 8 hours for a couple of days to confirm that there is no malaria infection. Place face downwards in Giemsa stain (1 drop of Giemsa per ml. Malaria parasites can be identified by examining under the microscope a drop of the patient's blood, spread out as a “blood smear” on a microscope slide. Ring form is early trophozoites. Prior to examination, the specimen is stained (most often with the Giemsa stain) to give the parasites a distinctive appearance. Pink ovals, 1-3 um in diameter C. Blue ovals, 4-6 um in diameter D. Fluorescent circles, 8-12 um in diameter Delay in preparation of the smears can result in changes in parasite morphology and staining characteristics. A 7-year-old girl from a malaria-endemic region visited the hospital with fever, chills, aches, and fatigue. Staining Blood Smears . It has the disadvantage of being relatively expensive, but this is outweighed by its stability over time and its consistent staining quality over a wide range of temperatures. Serologic … Staining of Blood parasites other than malaria parasites Species of microfilariae Method a. Parasitemia levels were routinely assessed using Giemsa staining of blood smears. Light-microscopic examination of a stained bone marrow specimen from a patient with visceral leishmaniasis—showing a macrophage (a special type of white blood cell) containing multiple Leishmania amastigotes (the tissue stage of the parasite). All smears (n = 30) found positive for asexual forms of malaria parasite by Giemsa stain in comparison to 29 by methylene blue stain [Table 1]. The Microscopical Appearances of a Successfully Stained Thick Film. Although this seems simple, the efficacy of the diagnosis is subject to many factors. ⇒ Firstly fix out the air-dried thin blood smear in the absolute methanol by dipping the blood smear quickly (two dips) in a Coplin jar containing absolute methanol. ⇒ Take out the slide from the Coplin jar and let it air dry. ⇒ Diluting the Giemsa Stain for Thin Blood smear: For staining the thin blood smear the Giemsa stain is used in 1:20. The malarial parasite can be seen through examining a blood smear slide beneath the microscope. Giemsa results in DNA (e.g. Note: If a rapid diagnosis of malaria is needed, thick films can be made slightly thinner than usual, allowed to dry for 1 h, and then stained. left in a buffer for 5 minutes. Malaria parasites can be identified by examining under the microscope a drop of the patient’s blood, spread out as a “blood smear” on a microscope slide. Get free Research Paper on malaria parasite and its effect to human health project topics and materials in Nigeria. Malaria microscopy allows the identification of different malaria-causing parasites (P. falciparum, P. vivax, P. malariae and P. ovale), their various parasite stages, including gametocytes, and the quantification of parasite density to monitor response to treatment. Stain only one set of smears, and leave the duplicates unstained. Free amastigote in a touch preparation (Giemsa stain, original magnification × 1000). It is a mixture of methylene blue and eosin and it differentially stains the RBC & platelets pink, WBC blue and MP purple. Slides are fixed in methanol for 2 minutes b. The malaria parasites are stained similar to staining with Giemsa (the red chromatin dots with light blue cytoplasm). If you are uncertain whether a particular object or structure is a malaria parasite, look for more typical forms. Laveran first discovered that an infectious agent was responsible for malaria by using a simple microscope, without the assistance of specific stains. Advice on the choice of slides and the cleaning of new and used slides is followed by a detailed account of the preparation of Giemsa stain, as used in the author's laboratory. P. falciparum. PRINCIPLE. Figure 1. A. Blot-like karyosome, no peripheral chromatin B. Moreover, Giemsa stain is used for the staining of blood and bone marrow films. Plasmodium falciparum is a unicellular protozoan parasite of humans, and the deadliest species of Plasmodium that causes malaria in humans. A modified trichrome stain of a fecal smear can be used to detect microsporidia. The Giemsa stain is used as the gold standard for the diagnosis of malaria on blood smears.The classical staining procedure requires between 30 and 45 … 109. 4. Gametocytes of Plasmodium vivax was seen in 83.3% (25/30) and 90% (27/30) of the blood smears stained with Giemsa and methylene blue stain, respectively. src: i.ytimg.com. Romanowsky stains are widely employed in microscopic visualization of parasites and blood cells. Giemsa stain Giemsa stain Giemsa stain is an alcohol-based Romansky stain. As we already know, the gold standard malaria diagnosing test is the screening of thick and thin blood smears with Romanowsky stain. In . 9 The intensity of the staining varies with the duration of stain contact time and concentration of the stain. Giemsa stain is a gold standard staining technique that is used for both thin and thick smears to examine blood for malaria parasites, a routine check-up for other blood parasites and to morphologically differentiate the nuclear and cytoplasm of Erythrocytes, leucocytes and Platelets and parasites. The thick smear is more helpful to find M.Parasites. Gametocytes of Plasmodium vivax was seen in 83.3% (25/30) and 90% (27/30) of the blood smears stained with Giemsa and methylene blue stain, respectively. Plasmodium different shapes are discussed before starting the actual life cycle. Slides are immersed in Giemsa Reagent to differentially stain specific cellular components. nuclei) staining purple and RNA (e.g. Giemsa stain named after German chemist and bacteriologist Gustav Giemsa, is used in cytogenetics and for the histopathological diagnosis of malaria and other parasites.Giemsa stain for blood films and for the Wolbach′s Giemsa method for … Laboratory diagnosis of malaria Staining for malaria parasites . Thick smears should be. Appearance (Form) Solid. be present in red cell without parasites. A drop of blood is unfolded on a slide which is referred to as smear. Blood smears are taken most often from a finger prick. Our knowledge of the Plasmodium life cycle and cellular biology has progressed with each technological advance, … #1 - Thick smear: To screen for parasite; A stick is used to spread the blood on the glass slide to a 50-cent coin area, yet thin enough to be seen through. P. vivax. For a 1:50 dilution, add 1 ml of stock Giemsa to … For perfect malaria staining, the pH of the buffer should be 7.2; Dry the slides upright in a rack. Well-stained thin blood film enables the differentiation easy for medical laboratory professionals. This procedure is to be modified only with the approval of the national coordinator for quality assurance of malaria … It is responsible for around 50% of all malaria cases. The appearance of P carinii cysts stained by this ... diagnosis ofhuman malaria L. A morphological study ofthe erythrocytic parasite in thick bloodfilms. Giemsa is a popular and cost effective stain that is generally used during staining process [81]. The films were lets to dry by air, staining with Giemsa stain for 10 minute and then examined for the first times with DW with objective lens and for the second times with synthetic oil. You must be able to distinguish the various parts of the parasites. Giemsa stain shows it as a blue stain cytoplasmic circle connected to a red chromatin dot. Malaria parasites pass through a number of developmental stages. Delay in preparation of the smears can result in changes in parasite morphol-ogy and staining characteristics. Giemsa stain is … Preparation of erythrocytes from whole blood and analysis on a cell microarray chip SYTO 59 was added to the erythrocyte suspension, and the mixture was subjected to analysis on a cell microarray chip as described above. ⇒ Now, stain the Air-dried Blood smear with diluted Giemsa stain (1:50, v/v) for 50 min. Two types of blood films are traditionally used: [3] Thin films - similar to usual blood films and allow species identification since the parasite's appearance is best preserved in this preparation. In . Note: If a rapid diagnosis of malaria is needed, thick films can be made slightly thinner than usual, allowed to dry for 1 h, and then stained. 2. DO NOT FIX. 3. Stain with diluted Giemsa stain (1:50, vol/vol) for 50 min. For a 1:50 dilution, add 1 ml of stock Giemsa to 50 ml of buffered water in a Coplin jar. Although stains like Leishman provide very good results for malaria parasites, Giemsa stain has proved to be the best all-round stain for the routine diagnosis of malaria. The parasite Endolimax nana trophozoite shows what type of nuclear appearance? Giemsa staining was used for the first two sporozoite challenge studies, and Field's stain in coplin jars for the later two studies. Abstract. Result Intermediate Cell - Blue Superficial Cell - Pink 98 MGG stain ( May Grunwald Giemsa’s Stain ) AIM This stain is done for any kind of FNAC slide or any kind of FNAC smear . You must be able to distinguish the various parts of the parasite, as shown in the diagram that follows. Identification of protozoa is mainly done using H&E stains. Giemsa stain. May-Grunwald Giemsa or Wright-Giemsa stain can also be used. Used in hematology, this stain is not optimal for blood parasites. Hi there! In the early 1900s, Gustav Giemsa designed the Giemsa stain to detect parasites such as malaria and Treponema pallidum in blood smears. Appearance of RBC Appearance of Parasite ... of different researchers in the area of malaria parasite recognition using computer ... of the parasite is possible and efficient via a chemical process called staining. Stain solution (40 ml): Dark blue 2. It has the disadvantage of being relatively expensive, but this is outweighed by its stability over time and its consistent staining quality over a wide range of temperatures. water) for one second, wash in distilled water. Collect blood 6 to 8 hourly till 48 hours to declare negative for malaria. We confine our discussion here to P. falciparum. 3. Recommended for detection and identification of blood parasites. C. Schüffner’s dots can be demonstrated in Giemsa stain, which is preferred to Wright or Wright-Giemsa stains. Leishman stain (CAS:12627-53-1, EC: 235-732-1, MFCD:00131498), also Leishman's stain, is used in microscopy for staining blood smears. Malaria is a serious mosquito-borne parasitic disease and is one of the most significant causes of death worldwide. Repeat the step 1-4 after culturing the parasite after one cycle (approximately 48 hrs). cytoplasm) staining blue. 3.0 MATERIALS AND METHOD. P. malariae. Solutions: Code number: 1040 ml: GIE61040 Colour 1. CHPATER FOUR for malaria parasites, such as bacteria, fungi, stain precipitation, and dirt and cell debris. Giemsa stain uses both thick and thin smears whereas wright stain uses only thin smear. It is then stained with Giemsa stain which supports by giving the malaria parasite a specific appearance. Effect of pH on Giemsa Staining of Malaria Parasites Artifacts That May Cause Confusion in Diagnosis Species Identification of Malaria Parasites Appearance of Parasite stages in Giemsa-Stained Thin and Thick blood Films Life Cycle of Malaria Parasites . The most commonly found parasite stages in P. falciparum positive blood films are ring forms (immature trophozoites). 3.6 Different Between Thick and Thin Film . stain, e.g. However, malaria parasites may be missed on a thin blood film when there is a low parasitaemia. infections, red blood cells (rbcs) can be normal to enlarged (up to 1 1/2× to 2×) in size and may be distorted. Free photo: drawing, appearance, thick, thin, blood smear, boxed, technique, malaria plasmodium, microscopy images, appearance, blood, cervical smear, coloration. Thus, it is an excellent stain for mass production in an epidemic situation. malaria parasites stains dark or purplishred, the cytoplasm stains blue, and the pigment granules vary withthe species from golden brown toalmost black. Giemsa stain is a gold standard staining technique that is used for both thin and thick smears to examine blood for malaria parasites, a routine check-up for other blood parasites and to morphologically differentiate the nuclear and cytoplasm of Erythrocytes, leucocytes and Platelets and parasites. Giemsa is a versatile, alcohol-based polychromatic stain. 2.1 The Stages of Different Species of Malaria Parasite . The importance, how to, effect causes relationship, comparison, history, role, solutions are discussed = Malaria parasites pass through a number of developmental stages. With a thick blood film, the red cells are approximately 6 - 20 layers thick which results in a larger volume of blood being examined. THICK BLOOD SMEAR SHOWING PLASMODIUM MALARIAE SCHIZONT CONTAINING 10 MEROZOITES The Giemsa stain is one of the best stains for malaria and other blood parasites and also satisfactory as a routine bloodstain to stain the Peripheral blood smear for the examinations of blood film under the microscope. Giemsa's solution is a mixture of methylene blue, eosin, and Azure B. Giemsa stain is a differential staining technique used primarily for staining of bacterial cells and also human cells. Test for differential staining of cells for detection of parasites by Giemsa stain. You can also use the Distilled water instead of buffer but the results may vary. The conventional method of diagnosing malaria is the microscopic examination of blood films using Giemsa staining[].It is inexpensive and reliable but requires considerable expertise and training of health care workers [].It is considered the most efficient method for the study of parasites in different stages and the quantification of parasitemia []. Then the sample is examined under the microscope in order to study the morphology of the infected blood cells and the presence of the malarial parasite. Congenital malaria is rare. Films that have an excessively red appearance have been differentiated in a Leishman stain more acid than pH 6"8. There are 100 giemsa-related words in total, with the top 5 most semantically related being malaria, dna, chromosome, parasite and phosphate.You can get the definition(s) of a word in the list below by tapping the question-mark icon next to it. These stains are also applied to detect the presence of parasites in the blood such as malaria parasites. In order to detect the infection it could be sufficient to divide stained objects into two groups such as parasite/non-parasite and differentiate between them. However, Giemsa stain is the best method for identification of protozoa. Stock 100× Giemsa Buffer – 0.67 M It can be used if rapid results are needed, but should be followed up when possible with a confirmatory Giemsa stain, so that Schüffner’s dots can be demonstrated. Table 1 shows the characteristics of the four main plasmodium species. It is generally used to differentiate and identify leucocytes, malaria parasites, and trypanosomas. The presence of malaria parasites in the fluorescence-positive erythorocytes was confirmed by Giemsa staining. 1. Principle. However, malaria parasites may be missed on a thin blood film when there is a low parasitaemia. Therefore, examination of a thick blood film is recommended. With a thick blood film, the red cells are approximately 6 - 20 layers thick which results in a larger volume of blood being examined. Field’s stain method for THICK blood films Description. Malaria parasites take up Giemsa stain in a special way in both thick and thin blood films. Below is a list of giemsa words - that is, words related to giemsa. ... seen in the clinical laboratory can easily be separated into two groups based on the macroscopic appearance of the colonies formed. Note: the appearance of Schüffner’s dots depends on the quality of the Giemsa stain. Staining: A number of Romanowsky stains like Field’s, Giemsa’s, Wright’s and Leishman’s are suitable for staining the smears. The thick film was air dried in both methods. Malaria parasites can be identified by examining under the microscope a drop of the patient's blood, spread out as a “blood smear” on a microscope slide. Parasitemia was also measured using the conventional method of Giemsa staining and microscopic examination. Effect of pH on Giemsa staining of malaria parasites. Differential counts and morphological characteristics of P. knowlesi parasites. Thick films are ideally stained by the rapid Field’s technique or Giemsa’s stain for screening of parasites. The calculation of parasitemia is discussed later. Prior to examination, the specimen is stained (most often with the Giemsa stain) to give the parasites a distinctive appearance Laboratory diagnosis of malaria . Giemsa is a versatile polychromatic stain, which is suitable for staining a diverse range of specimens. The thin smear is good to identify the type of malarial parasite. parasites in blood slides through a microscope by experts most of the cases by a pathologist. Malaria parasites were not found by microscopy with Giemsa staining in the remaining 4 blood samples (sample nos 21, 36, 38, 50) … 3.5 Giemsa Stain. Parts of a malaria parasite inside a red blood cell. Central karyosome, even peripheral chromatin C. Large karyosome, no peripheral chromatin D. Eccentric karyosome, uneven peripheral chromatin All smears (n = 30) found positive for asexual forms of malaria parasite by Giemsa stain in comparison to 29 by methylene blue stain [Table 1]. It is important to determine the adequate contact time with each new batch of stain made or procured. Prior to examination, the specimen is stained (most often with the Giemsa stain) to give the parasites a distinctive appearance. Note: As alternates to this 45-60 minutes in 2.5% Giemsa stain, the smears could be stained for shorter times in more concentrated stains. However, Giemsa stain is the best method for identification of protozoa. Thick blood films are stained by the following method: Dip in méthylène blue solution (1 part medicinal dye, 3 parts anhydrous disodium hydrogen phosphate, 1 part potassium dihydrogen phosphate in 300 ml. Malaria is caused by the protozoan parasite Plasmodium and is transmitted by infected mosquitos. Leishman stain. For all other sheathed microfilariae, proceed only to step iv. Identification of protozoa is mainly done using H&E stains. C. Schüffner’s dots can be demonstrated in Giemsa stain, which is preferred to Wright or Wright-Giemsa stains. The thick film is used for the detection of the presence of malaria parasites. of buffered water-7 parts Na2HPO4, 4 parts KH2PO4 … Giemsa [2], then rinsed and dried again. Has the fixative and stain separate (Giemsa's stain). The parasite is transmitted through the bite of a female Anopheles mosquito and causes the disease's most dangerous form, falciparum malaria. In . Appearance of cellular elements in Giemsa-stained thin and thick blood films: effect of pH on Giemsa staining of malaria parasites NC = LEUKOCYTES Thick Film — Lymphocyte, P = Platelets Eosinophil, M = Monocyte, L — CR NC Thin Film Neutrophil, E = MC PC Thin Film RC = In order to recognize malaria parasite, Giemsa stain can be used to be taken up by this parasite in a special way as well as in both thick and thin blood films. PURPOSE AND SCOPE To describe the procedure for properly staining malaria blood films with Giemsa stain. However, there is usually substantial debris in the background. 3.1 Materials Used. 8.2.1 Practical di culties in under-resourced health facili-ties. The diagnosis of Oroya fever is made by blood culture or by identifying B. bacilliformis organisms on Giemsa-stained blood smears. Melting point >300 °C. Since the visual ... is used to detect malaria parasite. Schüffner’s dots may not be visible in slides stained with Giemsa at pH <6.8 (Figure 1). Smears are fixed using the Giemsa Fixative. Malaria is the most important parasitic infection of man, and is associated with a huge burden of morbidity and mortality in many parts of the tropical world. For giemsa staining, the film was stood in 5% Giemsa for 30 minutes, then washed gently in tap water and air dried. Plasmodium is a genus of unicellular eukaryotes that are obligate parasites of vertebrates and insects.The life cycles of Plasmodium species involve development in a blood-feeding insect host which then injects parasites into a vertebrate host during a blood meal. Description. 4. The cellular components stain either basophilic (blue) or eosinophilic (orange granules). (3) Staining reaction. The latter will prove useful if a problem oc-curs during the staining process and/or if you wish later to send the smears to a reference laboratory. To make a 1:50 dilution of Giemsa stain, add 1 ml of stock solution of Giemsa stain to 49 ml of phosphate buffer solution in a clean Coplin jar. P. falciparum is therefore … Blood smear method (thick and thin blood smear) was performed for the microscopic examination, the intracellular parasite and its stages were identified which confirmed that the girl is diagnosed with malaria. These can frequently cause false positive readings [11]. For perfect malaria staining, the pH of the buffer should be 7.2. A. Purple circles, 10-15 um in diameter B. Recognition of a malaria parasite. Diagnosis of malaria involves identification of malaria parasite or its antigens/products in the blood of the patient. Recognition and detection of parasite in blood sample can be possible by applying a chemical process called (Giemsa) staining. Prior to examination, the specimen of the blood smear is stained mostly with Giemsa stain in order to give the parasites a distinctive appearance. ×) in size. If microfilariae of Loa loa, follow steps iii, iv, v and vi because the sheath of Loa loa does not stain with Giemsa. This is approved for students in accountancy business computer science economics engineering arts. Diluted stain solution (10 ml stain + 190 ml buffer solution): Blue 3. Keywords: Immunochromatographic test (ICT), Quantitative buffy coat (QBC), Giemsa staining, Acridine orange stain (AO) 1.Introduction . The preferred and most reliable diagnosis of malaria is microscopic examination of blood films, because each of the four major parasite species has distinguishing characteristics. Typically only rings and gametocytes are The desired standard for malaria staining is 7.2. Field’s stain method for THICK blood films Giemsa stain named after German chemist and bacteriologist Gustav Giemsa, is used in cytogenetics and for the histopathological diagnosis of malaria and other parasites.Giemsa stain for blood films and for the Wolbach′s Giemsa method for paraffin sections. since their Giemsa stain consists of Azure B, methylene blue, and eosin dye while the wright stain consists of eosin and methylene blue dyes. infections, red blood cells (rbcs) are normal in size. on February 22, 2021. The pH of the buffered saline used in the Giemsa stain is usually 6.8. Intraerythrocytic parasites on Giemsa stain is diagnostic. Parasites grow within a vertebrate body tissue (often the liver) before entering the bloodstream to infect red blood cells. Rings . 5. Wright stain is a differential staining technique used primarily in the staining procedures of blood smears, urine samples, and bone marrow aspirates. Malaria parasites can be identified by examining under the microscope a drop of the patient’s blood, spread out as a “blood smear” on a microscope slide. Parasite stages at hours 0, 6, and 12 of phase C were analyzed by flow cytometry as well as Giemsa staining. Prior to examination, the specimen is stained (most often with the Giemsa stain) to give the parasites a distinctive appearance. It provides excellent stain quality. Studies Second Ed. Stain with diluted Giemsa stain (1:50, vol/vol) for 50 min. Preparation ofthe smearandthe staining is similar to that used for normal haematology, except that Giemsa stain is used, and dilution is madein alkaline buffer (pH 7.2) instead of the usual slightly acidic buffer used by most haematologylaboratories. 3.3 Method of Sample analysis. The number of parasites in 100 μl of this suspension was then counted using the flow cytometer. The thick film was air dried in both methods. This is a ring-like malarial parasite following the invasion of RBCs. Mainly used for the cytogenetics and diagnosis of malaria and other parasites in histological sections. Prior to examination, the specimen is stained (most often with the Giemsa stain) to … 3.2 Sample Collection. In this report we discuss a case of a 26-year-old female healthcare worker who presented to the emergency department with signs and symptoms of persistent fevers, chills, headaches, nausea, and malaise. For giemsa staining, the film was stood in 5% Giemsa for 30 minutes, then washed gently in tap water and air dried. Moreover, Giemsa stain is used for the staining of blood and bone marrow films. Malaria microscopy allows the identification of different malaria-causing parasites (P. falciparum, P. vivax, P. malariae and P. ovale), their various parasite stages, including gametocytes, and the quantification of parasite density to monitor response to treatment. 2. Giemsa stain is used in understanding chromosome aberrations whereas wright stain to differentiate blood cell types. Synchronization was performed using the sorbitol lysis method 84. Remove thin smear slides and rinse by dipping 3-4 times in the Giemsa buffer. For this stain the smear should fixed in Methyl-alcohol for 15-20 minute . The procedure of staining with Field’s A and B … Giemsa stain is a gold standard staining technique that is used for both thin and thick smears to examine blood for malaria parasites, a routine check-up for other blood parasites and to morphologically differentiate the nuclear and cytoplasm of Erythrocytes, leucocytes and Platelets and parasites. Blood films showing various developmental stages of the malaria parasite Plasmodium falciparum, stained with Wright stain and Giemsa stain.
