摘要: 从江西省彭泽县某猪场出现咳嗽、呼吸困难、胸膜有化脓性纤维蛋白渗出物病变的病死猪中分离到4株革兰氏阴性细小杆菌,对其进行培养特性和生化特性鉴定;用副猪嗜血杆菌16S rRNA的特异性PCR引物,通过PCR技术可从分离菌中扩增出821 bp的特异基因片段,表明该分离菌株为副猪嗜血杆菌。药敏试验结果表明,4株分离菌对头孢唑啉高度敏感,对头孢哌酮、氯霉素等敏感,而对复方新诺明、青霉素G等有抵抗力。小白鼠攻毒试验结果显示4株分离株均有致病性。

Abstract: From Pengze county in Jiangxi province, 4 strains of Haemophilus parasuis were isolated from swines which were characterized by a fibrinous polyserositis, based on morphologic characteristics, cultural characteristics and biochemical characteristics of Haemophilus parasuis. According to the sequence of bacterial 16S rRNA, a PCR test to diagnose Haemophilus parasuis was developed, and it was used to identify the isolates. The results suggested that the isolates were Haemophilus parasuis. The mice virulence and drug sensitive tests showed that the strains were lethal to mice, sensitive to cefazolin, cefoperazone, chlormycetin and resistive to chemitrim, penicillin.

Key words: Haemophilus parasuis; isolation; identification; drug sensitive test; pathogenicity
