An adult male rhesus monkey (Macaca mulata) developed anorexia, ataxia, dullness, coughing, and some elevated body temperature and ided a week after the initiation of such symptoms. Body weight was 18.3 kg and the only notable gross lesion was the appearance of acute pneumonia with multiple nodules. Histopathologic observation of the tissues obtained from this animal revealed the features of acute primary pulmonary blastomycosis

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))

Pathological studies on 6 milk goats administered with urea were carried out to determine the effects of acute and chronic poisoning on the animal. Clinical signs appeared about 10 minutes after ingestion of the urea and they consisted chiefly in dullness, staggering, uncontrolled urination, dyspnoea, frothy salivation, bloating, muscular tremor, humping of back and tetanic spasms. Macroscopic lesions were failure of blood clot, frothy and bloody contents in the highly congested respiratory tract, pulmonary edema, rumenitis and abomatitis accompanying with petechiation of the upper small intestine. Microscopically, the liver showed vacuolar degeneration, fatty change and areas of necrosis and partial proliferation of the interlobular connective tissues in chronic cases. The renal epithelium displayed vacuolar degeneration, necrosis and hyaline casts in their lumens. In the lungs, there were hyperemia, edema, hemorrhages, and acute catarrhal bronchitis. Neuronal degeneration and necrosis in the central nervous system, cattarhal rumenitis, abomatitis, doudenitis and myocaridal hemorrhage were also demonstrated

Biochemical and antimicrobial susceptibility tests were conducted on 40 strains of Pseudomonas aeruginosa which originated from diseased chicken. An extensive study of the biochemical properties revealed that the tested strains can be identified with Pseudomonas aeruginosa. Antibiogram showed that all the strains were susceptible to gentamicin, colistin and amikacin but resistant to nitrofurantion, trimethoprim plus sulfamerthoxasole, ampicillin, methicillin and kanamycin and had varying degrees of resistance to other antimicrobials including carbenicillin, sulfomamides, neomycin, streptomycin, tetracycline and chloramphenicol. Three of the most frequent resistance patterns observed were FM (Nitrofurantoin) SXT (Sulfamethoxasole) AM (Ampicillin) ME (Methicillin) KM (Kanamycin) CM (Chloramphenicol) TC (Tetracycline) SM (Streptomycine) NE (Neomycine) SSS Pattern, FM SXT AM ME KM CM TC SM NE SSS CB (Carbenicillin) Pattern and FM SXT AM ME KM CM TC SM Pattern, and these resistance patterns contained 72.5% of the tested strains

This paper dealt with histopathological observations of the nephroblastoma in the pregnant pig which died 8 days before parturition day. In the necropsy findings the pregnant pig died of circulative and respiratory disturbance by compression of fetus and renal tumor weighing about 12 kg. In the microscopical findings of the renal tumor it was composed of well differentiated tumor cells and connective tissue elements. As differentiation of the neoplastic epithelial cells progressed, tubular and cystic structures, and papillary structures resembling glomeruli appeared. This tumor was regarded as nephroblastoma

A total of 136 dairy cows were subjected to test for bovine mastitis by AHI mastitis detector, microbiological test (MT) and California mastitis test (CMT). MT indicated that the most important causative microorganisms isolated from mastitis milk were Staphylococcus aureus (59.3%), Staphylococcus epidermidis (16.4%), Streptococcus agalactiae (12.4%) and Streptococcus uberis (4.4%). In Holstein breed, the critical threshold of electrical conductivity values of normal and mastitic milk were found to be less than 6,900 S and above, 7, 700 S, respectively. Although there was good agreement (92.0%) between AHI mastitis, the diagnostic efficiency of AHI mastitis detector (80.0%) was higher than that of CMT (74.0%) when compared with microbiological findings. In addition, handiness and objectivity of AHI mastitis detector for the detection of mastitic milk suggested that this could effectively be used for the diagnosis of both clinical and subclinical bovine mastitis in field

This experiment was conducted to compare six serological tests for diagnosing bovine brucellosis standard plate agglutination test (SPT), standard tube agglutination test (STT), complement fixation test (CFT), Rivanol test (RT), agar gel precipitation test (AGP) and counter immunoelectrophoresis (CIEP) in using 38 sera from brucella reactors and 222 sera from cattle. The SPT gave 1.6% apparent false negative reactions and 15.4% apparent false positive reactions when compared with STT which is an official test for bovine brucellosis in this country. The distribution of antibody titers determined by STT showed that 37.5% of 38 reactors had antibody titers of 400 or higher. When 38 reactors judged by STT were tested by CFT and RT, 32 cattle (82.4%) were positive by CFT and 33 catlle (86.8%) were positive by RT respectivily. This results suggest that Rt is comparable to CFT in the diagnosis of bovine brucellosis. The results also indicated that both AGP and CIEP were insensitive to detect brucella infection in cattle

A seroepidemiological survey on bovine leucosis virus was conducted. Serological studies were analyzed by age groups and the sizes of herds. The number of reactors increased gradually with the advance in the age of cattle and the herd size. The highest rate of BIV carriers was found in the ages between 6 and 8 years, and in the size of herds with 20 to 50 heads. Two out of 6 specimens (33.3%) from the reactors showed the typical type C virus with the size of 90 to 110 nm around microvilli and in intracytoplasmic vacuoles

This experiment was carried out to know the 133 isolates of yeast-like fungi. The antifungal agents tested were nystatin, griseofulvin, cycloheximide, 5-fluorocytosine, miconazol, clorimazole and tolnaftate. In general, clotrimazole, miconazol and 5-fluorocytosine were more effective in antifungal activity in vitro against the test organisms than the rest of the agents tested. However, some of the isolates showed higher resistance to certain antifungal agents compared to the other isolated of the same species. They were: 1C. albicans isolate to 5-fluorocytosine: 1 C. albicans to 5-fluorocytosine, miconazol and clotrimazole: 1 c. krusei to 5-fluorocytosine and cycloheximide; and 11 C. tropicalis isolates to cycloheximide. The minimum inhibitory concentrations (MIC) of clotrimazole were 12.5 mg/ml or lower for all isolates tested except one C. albicans isolate, for which MIC of the drug was 100 g/ml. On the other hand, the MIC's of cycloheximide were 6.5 mg/ml or lower for all isolates except the following: all isolates of C. albicans (100 mg/ml), 11 C. pseudotropicalis (200 mg/ml) and Rhodotorula sp. (25-50 mg/ml), 11 C. tropicalis isolates (100 mg/ml) and 1 C. Krusei isolate (200 mg/ml)

In order to know the morphology and the function of the fat-storing cells (FSC) of the squirrels which were captured at the Pal-Gong mountain near Taegu, Korea [R.] in December, 1980 (Group A) and May, 1981 (Group B), respectively, light and electron microscopic observations were conducted on the liver of the squirrels. Light microscopically, the size of the lipid droplets in the FSC of group A was uniformly larger than those in the cells of group B, and number of the droplets in the FSC of group A was less than those in the cells of Group B. The distribution of the FSC of group A was mainly perilobular area while those of group B were centrolobular and midzonal areas. In this method, the FSC of the squirrels was similar to those cells of the hamsters. Electron microscopically, general morphology of the squirrel's FSC was accorded with those of the other mammals. However, the rough surfaced endoplasmic reticulum in the FSC of group B was more dilated than those in the cells of group A, and more lipid droplets and pinocytotic vesicles were observed in the FSC of group B than those in the cells of group A. From those evidences, it could be suggested that the metabolic rates in the FSC of the squirrels collected in the spring were higher than those in the cells of the animals collected in the winter.
