김봉환,박후열,장인호 경북대학교 농업과학기술연구소 1984 慶北大農學誌 Vol.2 No.-

1984년(年) 10월(月)부터 1985년(年) 8월말(月末)사이에 대학부속가축병원(大學附屬家畜病院)에 검진의뢰(檢診依賴)된 대구(大邱) 경북지방(慶北地方)에서 발생(發生)한 83례(例)의 만성(慢性) 유방염(乳房炎)의 원인균(原因菌)을 분리(分離) 동정(同定)하고 이 분리균(分離菌)의 각종(各種) 항생제(抗生劑)에 대한 감수성(感受性)을 disc diffusion technique로 조사(調査)하였다. 대구(大邱) 경북지방(慶北地方)에서 문제되는 만성(慢性) 유방염(乳房炎)은 포도구균성 유방염(乳房炎)이 전체의 48.2%(83례중(例中) 40례(例))로 가장 많았으며 그 다음은 대장균군(大腸菌群) 유방염(乳房炎)으로 18.1%(83례중(例中) 15례(例))를 차지하였다. 효모양진균에 의한 유방염(乳房炎)도 10.8%(83례중(例中) 9례(例))나 되었다. Corynebacterium spp.에 의한 유방염(乳房炎)은 8.4%였으나 연쇄구균성 유방염(乳房炎)은 3.6%에 지나지 않았다. Bacillus spp.와 pseudomonad에 의한 것은 각각 3.6%와 8.4%이었으며 만성(慢性) 유방염(乳房炎)의 원인균(原因菌)을 밝힐 수 있었던 것은 4.8%(83 례중(例中) 4례(例))이였다. 만성(慢性) 유방염(乳房炎)에 관여한 포도구균과 대장균(大腸菌)은 공시(供試)한 항상제(抗生劑)에 대하여 내성(耐性)을 나타내는 경향이 뚜렷하였다. 포도구균은 penicillin, methicillin, linocomycin, novobiocin, ampicillin, tetracycline에는 각각 87.2%, 78.7%, 68.1%, 61.7%, 57.4%가 내성(耐性)인 반면에 gentamicin, cephalothin, chloramphenicol, erythromycin 등에는 각각 78.7%, 76.6%, 74.5%, 63.7%가 감수성(感受性)이었다. 대장균(大腸菌)은 streptomycin과 cephalothin에는 72.2%, tetracycline에 66.7%, ampicillin에 61.1%가 내성(耐性)인 반면에 colistin, gentamicin, chloramphenicol, neomycin에는 각각 83.3%, 77.8%, 66.7%, 55.6%가 감수성(感受性)이었다. Corynebacterium spp.는 ampicillin, chloramphenicol, erythromycin, gentamicin, oleandomycin, tetracycline에는 감수성(感受性)이었으나 novobiocin과 penicillin 등에는 내성(耐性)이었다. 한편 pseudomonas aeruginosa는 공시(供試)한 모든 항생제(抗生劑)에 내성(耐性)이었다. Some investigations on chronic mastitis in dairy cattle in Taegu-Kyungpook Provinces from the beginning of October, 1984 till the end of August, 1985 were conducted with the particular regard to the causative agents and their drug susceptibility. Milk samples from 83 isolated cases of chronic mastitis cattle were investigated bacteriologically and the causative organisms recovered were examined for their antibiotic susceptibility by using disc diffusion susceptibility technique against the major antibiotics of current veterinary use. Major causative agents involved in chronic mastitis in Taegu-Kyungpook Provinces were in order of prevalence Staphylococcus spp. (48.2 %), Escherichia coli (18.1 %), Candida spp. (10.8 %) and Corynebacterium spp. (8.4 %), Streptococcus agalactiae (3.6 %), Bacillus cereus (3.6 %) and Pseudomonas aeruginosa (2.4 %) were found to be one of the minor agents. The majority of staphylococcal isolates and E. coli were highly resistant to the most antibiotics tested. The percentages of staphylococcal cultures resistant to penicillin, methicillin, lincomycin, novobiocin, ampicillin and tetracycline were 87.2 %, 78.7 %, 68.1 %, 61.7% and 57.4 %, respectively, while the majority of them were susceptible to gentamicin(78.7 %), cephalothin(76.6 %) and chloramphenicol (74.5%). E. coli isolates were found to be highly resistant to streptomycin, cephalothin, tetracycline and ampicillin while the majority of them were susceptible to colistin (83.3 %), gentamicin (77.8 %) and chloramphenicol (66.7 %). Corynebacterium spp. were susceptible to ampicillin, chloramphenicol, erythromycin, gentamicin, oleandomycin and tetracycline although they showed resistance to novobiocin and penicillin. Two cultures of Pseudomonas aeruginosa recovered from mastitis milk were highly resistant to the antibiotics employed in the present study.

돼지 흉막폐렴(胸膜肺炎)의 발생(發生)

이현범,이근우,박후열,권오덕,Lee, Hyun-beom,Lee, Keun-woo,Park, Hoo-yeol,Kwon, Oh-deog 대한수의학회 1984 大韓獸醫學會誌 Vol.24 No.1

Authors observed an outbreak of porcine pleuropneumonia at a piggery in Gyeongbug, Korea, which were diagnosed on the ground of clinical and pathological findings with the following results. 1. One hundred and forty weanlings out of 200 ones died suddenly without noticiable signs during the period of 15 days. All of the dead pigs showed formy, blood-tinged discharge from the nose and mouth. 2. Main clinical findings observed from 60 alive pigs from group consisted of fever, cyanosis severe degree of dyspnea and pleuritic friction rub. 3. On hematological observation for typical 5 cases leukocytes showed marked degenerative left shift with leukopenia (10500-13070/cmm), neutropenia (7-13%) and increase in the number of band neutrophils (6-27%). 4. The most prominent and constant pathological changes observed at necropsy for dead or alive pigs consisted of fibrinous pleurisy with partial adhesion, overlying of the pulmonary surface with fibrinous menbrane and necrotic pneumonic lesions with marked edema and congestion of lung parenchyma. 5. From these results the outbreak was considered to be typical porcine pleuropneumonia, although no bacteriological isolation was attempted.
