가토(家兎)의 Pasteurella성폐염(性肺炎) (Snuffles)에 관(關)한 병리학적(病理學的) 검색(檢索)
권영방,임창형,Kwon, Young Bang,Lim, Chang Hyeong 대한수의학회 1968 大韓獸醫學會誌 Vol.8 No.1
Pathological studies on the Enzootic Pasteurellosis of domestic rabbits were performed and discussed. The chief pathological findings were as follows: Grossly, pneumonic lesions were located mainly in apical and cardiac lobes. The lesions were well demarcated with unaffected surrounding tissue. The pleural surface of pneumonic lesions were usually appeared as yellowish~white fibrinous exudate and, in some cases, abscesses were also shown. Microscopically, various cellular exudates composed mainly of neutrophils, large monocytes and lymphocytes were observed in the alveolar spaces. Some alveolar spaces were filled mostly with fibrinous exudates. Occasionally, thrombosis accompanied with infarcts were encountered in pneumonic lesions. There were deposition of purulo-fibrinous exudates on the visceral pleura.

The effects on CTC (T1) and CTC, Sulfathiazole and Penicillin Combination (T2) medication in feed through one life cycle of pigs, namely, weaning, mating, farrowing, lactation, growing, finishing and slaughter, were tested under local condition. In sow phase, productivity and the number of microflora in urine before and after medication of CTC were studied and average daily gain and feed conversion rate were checked during growing and finishing period. All pigs reached at 155 days old were slaughtered for pathological examination. 1. Litter size, farrowing rate and survival rate at birth were improved by CTC medication from weaning to 21th day after mating and mortality of piglet at weaning, 25 days after farrowing, was reduced in the CTC medication group, but no siginificant. 2. The number of microflora in the sow urine was changed with the medication at 200ppm of CTC in feed. In particular, the number of E coli, Samonella and Staphylococci were reduced by CTC medication. 3. The average daily gain and feed conversion rate of grower and finisher pigs was improved significantly in both treated groups, most in the high level CTC (T1) medicated group and was lowest in the control group. 4. The number of infected lungs was reduced not significant by both treatments (as % pneumonic lesions Co 66.7%, T1 47.1%, T2 31.4%) and the severity of lung lesions was significantly reduced by both high level of CTC and CTC combination medication in feed. 5. Although there were no statistical differences in atrophic rhinitis based on turbinate scores among the 3 groups, the number of mild and moderate (Grade 2 and 3) infections was higher in the control group (9/36) than in the treated groups (T1 2/34 & T2 4/35).

The outbreak of hepatosis dietetica from 2 different herds of pigs was diagnosed for the first time in Korea. The livers from 5 affected pigs showed yellow atrophy, necrotic foci and ecchymotic hemorrhages anatomically, and hemorrhagic necrotic hepatitis histopathologically.

Severe ulcerative colitis and cecitis by Balantidium coli was studied pathologically in a 40 day old male pig. Grossly, many variable-sized ulcers were diffusely scattered on the mucosa of the cecum and the colon. Microscopically, numerous balantidia pene

1. The sixty raised shepherd and sixty-five inhoused pet dogs in the regions of Daejon and Cheongju were subjected to investigate the TB infection by means of BCG and X-ray diagnosis. The 5 out of 65 inhoused pet and 7 out of 60 shepherd dogs were observed to be infected with TB, respectively. However, none of Mycobacterium species were detected from lung tissues of 4-slaughtered dogs showing BCG positive reaction. 2. The rats were first inoculated with 0.1ml BCG, and then 0.1ml M bovis suspended solution($1{\times}10^5$ organisms/0.2ml) 3weeks later. After 5 months, the animals were killed. The pathohistological results from both groups, TB inoculated and BCG treated groups, were observed on the surface of lung. Furthermore, the severe pathological lesion in the Iung was observed in M bovis inoculated group compared to BCG treated group. 3. The slight macrophage invasion and granuloma formation in the lung from BCG treated group were observe individually. However, it was confirmed that the lung from M bovis treated group was invaded by the macrophages and neutrophils combined with the granuloma formation. 4. When the numbers of the total cells taken from broncho-alvealar fluid in each of mouse from both groups were differentially counted, the number of total cell, neutrophils, and lymphocytes from M bovis treated group were significantly increase compared with those of BCG treated group. 5. Although there were nearly no response of the alveolar macrophages to CSF in serum obtained from control group, those from M boris treated group were significantly proliferated.

Johne's disease로 추정된 한우를 병리학적으로 검사한 결과, 병리해부소견으로는 장점막의 비후와 장벽의 비대 그리고 병리조직학적으로는 점막고유층과 점막층, 점막하직에 다량증식되어 있는 유상피세포와 그 세포질에 탐식되어 있는 항산성균을 관찰하였기에 Johne's disease로 확인되었다. Pathological study on the Johne's disease of Korean native bull was conducted at August 1983 in Kyunggi province. 5 years old bull was continued with watery, odourless diarrhea for 6 month and appetite was within normal. Clinicohematological examination o
