犬瘟热肠道菌群的变化及药敏试验

Changes and Drug Sensitiveness of Microbial Population in Intestinal Tract of Canine Distemper

犬瘟热是引起犬科动物的一种高致死性疾病,极大的危害着养犬业的发展。本试验对云南农业大学动物医院患犬瘟热肠炎型的病犬进行血常规检测、细菌的分离培养及初步鉴定、药敏试验,发现该病在白细胞上升时存在较重继发感染,而白细胞下降也同样存在感染,在感染菌中以大肠杆菌和沙门氏菌为主,它们对头孢噻肟、头孢噻吩、丁胺卡那等药物敏感,可用作治疗。

Canine distemper is a kind of highly fatal disease of caninidae, which prevent the development of canine breeding seriously. This experiment includes blood normal detection, bacterial isolated culture and initial identification, susceptibility test,the materials were gained from canine of yunnan agricultural university animal hospital, which was infected with coninedistemper enterites, the results showed that count of RBC increase will lead to seriousinfection, and count of WBC drop off also exist infection. The Esherichia coli and Salmoella were major pathogenic bacterium,they were sensitive to most medicine drug, such as cefotaxime, cefalotine and so on, so cant be used for treating.
