  • Several methods have been used in the detection of Helicobacter pylori (H. pylori) which was believed to be a pathogenic organism causing chronic gastritis, benign peptic ulcer, gastric carcinoma or malignant lymphoma. Even though several methods were introduced for detection of H. pylori in stomach, there were controversies in their sensitivities and specificities. This experiment were designed to study the comparative analysis of staining methods (hematoxylin and eosin (H&E), Giemsa, Warthin-Starry and immunohistochemical stain) to dectect H. pylori in the gastric mucosa. The results were as follows. Average density score of H. pylori classified by Genta were 2.29 in Warthin-Starry stain, 2.19 in Giemsa stain, 1.34 in immunohistochemical stain and 0.98 in H&E stain. By comparison between inflammatory degree by Sydney system and result of Warthin-Starry stain, the detection rate and densities of H. pylori were increased from mild (61.5% and 0.8), moderate (90.4 and 2.1), and severe (100% and 3.2). From the above findings, Warthin-Starry stain is useful method for detection of H. pylori in gastric mucosa.

  • The application of Giemsa technique to stain compressed diaphragm samples obtained from rodents experimentally infected with Trichinella spiralis is described. Diaphragm samples from rats heavily infected with 20 muscle larvae per gram of body weight(20 ML/gbw) were cut into several pieces and stained with Giemsa; on the other hand, whole diaphragms from slightly infected mice(1 ML/gbw) were also stained with Giemsa. Besides, muscle samples were also stained with Giemsa. Observation at 10 $\times$ magnification revealed that both ML and nurse cells(NC) look as bluish structures clearly contrasting with the pinkish color of the non-infected muscle fibers. NC in the diaphragms of mice could be easily observed at naked eye as blue points contrasting with the pink surrounding areas formed by the non-infected muscle fibers. Among NC observed in the diaphragms of rats infected with 20 ML/gbw, 4.4% was multiple infection. These findings were confirmed in sectioned and hematoxylin-eosin stained specimens. This data could be usefulness for a rapid diagnosis of trichinellosis in post-mortem mammals without magnification procedures.

  • Diagnosis of cryptosporidiosis is currently confirmed by the detection of the oocysts or endogenous stages in fecal or tissue samples. Various conventional staining methods and serodiagnostic techniques have been reported, but the latter has far been limited to a few laboratories. Cryptosporidium has recently been reported in mice and chiekens in Korea, but there has been no report on staining methods to the oocysts. The present study was performed by light and scanning electron microscopic observations, and discussed with staining properties of four conventional methods such as dichromate solution floatation method, Carbol fuchsin stain, Auramine-O stain and Giemsa stain method. Cryptosporidial oocysts were isolated from the laboratory mouse. In tissue sections of duodenum, jejunum, ileum, cecum and upper colon, numerous very small, basophilic bodies were observed on the border of mucosal epithelial cells. In scanning electron microscopic observations, a few of developmental stages of Cryptosporidium were seen. Two types of thick and thin-walled oocysts were recognized in the intestinal contents. Mean size of its were $5.19{\pm}0.23{\times}4.31{\pm}0.32{\mu}m$ and $5.14{\pm}0.25{\times}4.27{\pm}0.4{\mu}m$, respectively. Carbol fuchsin and Auramine-O stain methods are recommended as the satisfactory ones for the identification of Cryptosporidium oocysts. Giemsa stain was also recommended as available in the laboratory, because a few of developmental stage fo Cryptosporidium could be seen by it.

  • The life cycle of Theileria sergenti(T sergenti) in cattle, especially Korean native cattle, was not proved clearly. To find schizont stage in the life cycle of T sergenti in Korean cattle, T sergenti schizonts in the cells of parotid lymph nodes from 10 adult Korean cattle were examined. Lymphoid cells which were separated from these lymph nodes were cytocentrifuged to observe the parasites in the cells. T sergenti schizonts were detected in the cells of lymph nodes of 6 cattle out of them by IFA(Indirect Fluorescent Antibody) test and Giemsa stain. By peroxidase stain, the cells which contain schizonts were proved lymphoid cells. T sergenti schizonts identified by IFA test were able to be restained by Giemsa stain. Also, merozoites were observed in peripheral blood of the same 6 cattle that had schizonts, by giemsa stain, but not observed in the 4 cattle that had not been detected schizonts. As a part of life cycle of T sergenti, schizonts were observed in the lymphoid cells of Korean cattle.

  • Recently, the Acridine orange (AO) staining method has improved for identification of malaria parasites. Fixed and preserved blood smears of malaria patients were used for comparative analysis of AO and Giemsa stains. The AO staining method required less time and was more sensitive under lower magnification than the Giemsa staining method . The AO staining method provides an alternative to Giemsa for malaria diagnosis in the field and laboratory.

  • The rate of 58 neonatal calves in infection of Theileria sergenti was investigated in random samples on the farms located in Kyunggi, Chonbuk districts of Korea. 1. The criteria used in veryfying infection with T. sergenti included the detection of parasites by giemsa stain and acridine orange stain in the blood smear slides. 2. Further evidence of current or previous exposure to T. sergenti was based on demonstration of T. sergenti specific antibody and antigen by the western immunoblot and the directed immunofluorescent antibody test in the peripherial blood of the calves. 3. The prevalence rates were 35%, 50% in Kyunggi, Chonbuk provinces respectively and the overall prevalence in all the farms was 43.2% by means of acridine orange stain. 4. The parasites that were observed in the peripherial blood of calves was showen surely by the western immunoblot to the characteristic 34KD antigen among the proteins of T. sergenti (Korean isolate). 5. And the antigen of the neonatal calves reacted at the very highest titer(1 : 2, 560) 6. These data highlight the significances of T. sergenti in the neonatal calf disease in Korea.

  • A technique to improve the analysis of micronuclei(MN) in lymphocytes as a cytogenetic indicator is reported. For the purpose of diminishing the variation of the result from individual reader and making it easier to distinguish accurately a cytokinesis blicked(CB) lymphocyte and micronuclei, we tried a modified one-step silver staining technique as a method for detection of the argyrophilic nucleolar organizer region(AgNOR) with or without conventional Giemsa stain in the slide from CB method. Compared with the conventional Giemsa stain, the preparation processed with this method are especially useful for the accurate analysis of MN of cultured lymphocyte with cytochalasin B. This method will be a useful technique for automated calculation of MN.

  • Dogs with canine babesiosis may present with wide variation in the severity of clinical signs, ranging from a hyperacute, shock-associated, hemolytic crisis to an inapparent, subclinical infection. Dogs typically present with the acute form of babesiosis, which is characterized by general findings such as pyrexia, weakness, mucous membrane pallor, depression, hemorrhagic anemia. This study was conducted to investigate the prevalence of babesia spp. infection in dogs of Seogwipo-si. A survey of canine babesia spp. infections among 173 dogs in Seogwipo-si was performed from July 2008 to August 2008. Blood samples were collected from dogs raised outdoors through cephalic or jugular vein and Babesia spp. was diagnosed by examination of blood smear stained with Giemsa stain. Of 173 dogs, 9 dogs (5.2%) were infected with the babesia spp. This result was a little lower than the prevalence of Babesia spp. in dogs of other areas.

  • Application of a commercial Diff-Quick kit for fish hematology was evaluated. Diff-Quick stain was incomplete in staining not only the nucleus and cytoplasm but also granules of leucocytes that were stained in soluton I and II for five seconds. However, when the staining time changed to 5 seconds in solution I and 10 seconds in solution II, followed by washing with deionized distilled water, the kit showed the similar results as in May-Grunwald Giemsa stain. The results indicate that the kit can be used in fish hematology for rapid staining.
