This study was conducted to investigate in the infection rate of common internal parasites in dogs in Kwangju area (Korea R.) from January to March, 1982. Dog's stools were collected from veterinary hospitals, houses, intensive dog-rearing places and sidewalks. On the basis of egg counting, of 464 fecal samples, 73.5% were appeared as positive. Dogs from veterinary hospitals and intensive dog-rearing places have higher infection rates than others. Of the parasites detected, Toxocara canis was the most commonly encountered (23.7%). Ascarids, flukes and coccidia were more prevalent in pups than in mature dogs, whereas hookworms were detected less often in young dogs than in older ones. There were significant (p0.01) differences among age categories for all parasites except tapeworms

This study was conducted to clarify the presence or absence of isohemagglutinin and isohemolysin in the formosan deer. Using 4 rabbit immune sera to different deer blood cells following blood types were recognized among 30 heads of deer. These are by hemagglutination test (A: positive to all 4 immune sera (13 heads)), of 1BS and 3BS (8 heads), C: positive to the sera of 3BS, 7BS and 8BS but negative to that of 1BS (9 heads)), by hemolysis test (A: positive to all 4 immune sera (24 heads), B: positive to the immune sera of 7BS and 8BS but negative to those of 1BS and 3BS (3 heads)), C: positive to the sera of 3BS, 7BS and 8BS but negative to that of 1BS (3 heads))

The histopathological changes in the mammary gland of lactating rats and rabbits injected with dexamethasone were observed. In the mammary glands of rats, the microscopic findings encounted were decrease of milk in the alveolar lumina, necrosis and dequamation of epithelial cells, atrophy of alveoli, proliferation of fibroblasts and thickness of alveolar walls, destruction of alveoli, presence of fat droplets within the glandular epithelial cells, infiltration of mononuclear cells and proliferation of adipose tissue, which were relative to the dose and duration of injection

This study was carried out to investigate a case of elk babesiosis in Daegu Korea [R.]. Hematologically, the erythrocyte count was 1.93 million/cu.mm, 11% of which were infected with Babesia. Most (88%) of the protozoa were spherical or vacuolated ring form in shape, resembling B. bovis. The sizes (0.98-2.85) were slightly smaller than the latter. About 7% of the protozoa were vacuolated oval, the size of which varied from 2.06-2.95 x 1.08-1.97 (2.53 x 1.51 in average). The remaining 5% were irregular in shape
