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

The modified drug sensitivity test for the shortening of detection time and clinical application was evaluated. Inhibitory zone in 6 strains of Staphylococcus and Escherichia coli tested to sensitivity test were reached at 100% between 2 and 6 hrs. The sensitivity test of Staphylococcus A.B and E. coli No. 2, No. 3 to antibacterial injection drugs in 6hrs after treatment were strongly positive (+++), and Staphylococcus A. A. and E. coli No. 1 were moderately positive (++). This modified method detected 86% degree of sensitivity between 7-12hrs after treatment

The histopathological changes on the cardiac and skeletal muscles, and liver of rabbits fed commercial ration were observed. In the skeletal muscle, light microscopic changes observed were cloudy swelling, hyaline degeneration, atrophy, fragmentation and coagulative necrosis of muscle fibers, and proliferation of fibroblasts and infiltration of mononuclear cells. In the myocardium, loss of muscle fibers with necrosis and vacuolization, hyaline degeneration, hemorrhage and congestion were noted

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
