To determine the prevalence and the morphological identification of two Eimeria species in fecal examinations, a total of 1092 fecal specimens collected during the period of March to December in 1987 was tested by means of flotation technique. The prevalence of two species was revealed as 1.83% and 0.92% in E. bukidnonensis and E. wyomingensis, respectively. The oocysts of E. bukidnonensis measured in range of 41.3 micro m to 49.4 micro m (mean 45.5+-1.7) x 28.8 micro m to 35.3 micro m (mean 32.2 +-1.2), and E. wyomingensis 36.9 micro m to 44.5 micro m (mean 39.8+-1.7) x 26.5 micro m to 29.9 micro m (mean 28.2+-0.9). The oocysts of E. bukidnonensis appeared darker and more robust than those of E. wyomingensis. The striations in the oocyst wall of E. bukidnonensis were more peculiar than in E. wyomingensis. Among the morphological characteristics, the widths could be reliably taken as a differential point of view for two Eimeria species

Some hematological and biochemical indices were assayed in Korean native cattle naturally harbouring Fasciola hepatica infection and compared with uninfected controls. Affected animals revealed reduction in total erythrocyte count and hemoglobin content, and increase in total leukocyte count. Infected cattle had significantly lower levels of serum total protein, serum albumin and magnesium. Significantly higher values were obtained for the serum enzymes asparate aminotransferase and alanine aminotransferase

Samples of feces from 1,080 cattle than in Chonnam area were examined for Buxtonella sulcata. Of these, 231 cattle (21.4%) were found to be infected with the ciliate. The incidence was higher in the dairy cattle in the beef cattle. The cysts of the ciliate were almost spherical or sub-spherical and the mean length of 79.58 +- 11.76 micro m corresponds quite closely with the mean width of 77.29 +- 11.41 micro m. The trophozoite was characterized by the position of the cytostome near the open cytopyge and by the curved groove running down from cytostome to the end of the body

This paper deals with the isolation of Salmonella on 3 herds during the period from May 1984 to May 1985. Isolated Salmonella were examined for serotypes, adhesive fimbriae, antibiotic susceptibility and detection of R plasmid. Of total 1505 cattle, 24 Salmonella were isolated from 18 cattle (1.2%) and their serotypes were S. enteritidis (9 strains), S. derby (4 strains), S. infantis (1 strain), C1 group (8 strains), C2 group (1 strain) and untypable (1 strain). Twelve strains of Salmonella were isolated from 227 cattle with diarrhea and their serotypes were S. enteritidis (4 strains), S. derby (3 strains), S. infantis (1 strain), C1 group (3 strains) and untypable (1 strain)

This paper dealt with the distribution of normal mast cells in the spleen, liver and lung on cattle, horses, pigs and dogs, and also degranulation of mast cells in the dogs injected with Rompun (2% Xylazine HCl). Normal mast cells were distributed in spleen, liver and lung on cattle, horse, pig and dog. Mast cells were observed in both red pulp and surroundings of white pulp of the spleen in horse, in the white pulp of the spleen in cattle, in the trabeculae of the spleen in pigs, and in white pulp and red pulp of the spleen in dogs

Incidence of foot disease of Korean native cattle (231 cases) and Holstein (310 cases) in slaughter house was observed from Jul to Aug, 1984. Incidence rate of foot disease was 9.09%, 12.90% and 11. 27% for Korean native cattle, Holstein and total respectively. Chronic necrotic pododermatitis showed the highest incidence among all foot disease and its incidence rate was 6.47% in all cattle observed
