摘要
本试验随机采集30份藏猪腹泻物样本,通过细菌的分离培养、形态学观察、PCR扩增测序等,鉴定得出两种主要细菌:大肠杆菌和变形杆菌。药敏试验分析表明,混合菌对头孢曲松极度敏感,对丁胺卡那霉素高度敏感,对恩诺沙星、新霉素、氟苯尼考、庆大霉素、强力霉素、四环素低度敏感,对复方新诺明、链霉素、氨苄西林、青霉素耐药。
30 samples of the Tibetan pig diarrhea were collected randomly in this experoment, two main bacteria(Escherichia coli and Proteus) had been identified by bacterial isolation,morphological observation, PCR amplification and sequencing. According to the drug sensitive test, mixed bacteria were extremely sensitive to ceftriaxone,highly sensitive to amikacin,less sensitive to enrofloxacin,neomycin,florfenicol, gentamicin, doxycycline and tetracycline, resistant to compound sulfamethoxazole, streptomycin,ampicillin and penicillin.
