天津某规模化猪场一例仔猪水肿病的诊断分析

Diagnostic Analysis of Piglet Edema Disease from a Large Scale Pig Farm in Tianjin

2015年9月于天津某规模化猪场发现疑似仔猪水肿病病例,经无菌采集病变明显的组织器官,通过细菌分离与培养、镜检、生化鉴定、病毒培养等实验室检测方法进行综合诊断,同时结合病猪的流行病学调查、临床症状和病理剖检变化,最终确诊为仔猪水肿病。药敏试验结果表明,该分离株大肠杆菌对头孢唑啉、多西环素等药物高度敏感。该结果为仔猪水肿病的临床快速诊断和用药提供了借鉴。

In septemper 2015, the obvious lesion tissues and organs were isolated under sterile conditions from suspicious piglet edema disease from a large scale pig farm in Tianjin. Comprehensive diagnoses which included bacteria separation and culture, microscopy, biochemical tests and viral culture were performed. Considering the epidemiological investigation, clinical symptoms and pathological changes, it was confirmed that infected pigs suffered from piglet edema disease caused by Escherichia coIi. The drug sensitivity test revealed that the isolated bacterial strain was highly sensitive to cefazolin and doxycycline. The diagnosis results provide the reference for rapid diagnosis and clinical medication of the piglet edema disease.
