兔支气管败血波氏杆菌的分离与鉴定

为鉴定从临床获得的病死成年兔中分离到的一株革兰氏阴性杆菌,应用VITEK 2 Compact全自动微生物分析系统仪完成细菌生化鉴定及药敏试验,并对16S rRNA基因测序鉴定,通过MegAlign（Lasergene7.1）及Phylogenetic（Lasergene7.1）绘制进化树及同源性比较以了解该株细菌的遗传进化关系。结果表明此株细菌是支气管败血波氏杆菌,并与BX640428等序列同源性高达100%。生化试验及药敏试验结果表明谷氨酰芳胺酶pNA试验、L-脯氨酸芳胺酶试验、酪氨酸芳胺酶试验、尿素酶试验、柠檬酸盐（钠）试验、L-乳酸产碱试验、琥珀酸盐产碱试验为阳性,对头孢替坦、头孢唑啉、呋喃妥因具有耐药性。     

兔源支气管败血波氏杆菌和肺炎克雷伯菌的分离鉴定及其对抗菌药物的敏感性分析

兔感染支气管败血波氏杆菌(Bordetella bronchiseptica)和肺炎克雷伯菌(Klebsiella pneumoniae)后,常引起兔多发性呼吸道疾病,严重危害家兔养殖业.作者剖检河南省某兔场疑似病死兔,并采集组织分离鉴定病原菌,然后进行药敏试验,以期确定引起兔呼吸困难、腹泻的病原.结果 显示,经细菌分...     

福建省部分地区兔波氏杆菌病和巴氏杆菌病的流行病学调查

为了解福建省兔群中波氏杆菌和巴氏杆菌的流行情况,通过细菌分离鉴定,对2017年10月-2018年11月期间采集自福建省福州市、南平市和龙岩市9个兔场的243份病死兔肺脏进行支气管败血波氏杆菌(Bb)和多杀性巴氏杆菌(Pm)检测。结果显示:9个兔场均有Bb和Pm感染,Bb阳性样品占54.73%(133/243),Pm阳性样品占38.68%(94/243),双阳性样品占14.81%(36/243)。说明Bb和Pm在福建省的兔群中普遍存在,且还存在混合感染。     

Bordetella bronchiseptica in a paediatric cystic fibrosis patient: possible transmission from a household cat

Bordetella bronchiseptica is a zoonotic respiratory pathogen commonly found in domesticated farm and companion animals, including dogs and cats. Here, we report isolation of B. bronchiseptica from a sputum sample of a cystic fibrosis patient recently exposed to a kitten with an acute respiratory illness. Genetic characterization of the isolate and comparison with other isolates of human or feline origin strongly suggest that the kitten was the source of infection.

兔支气管败血性波氏杆菌fimN基因的原核表达

应用PCR方法扩增兔支气管波氏杆菌(Bb)的菌毛蛋白基因( fimN),将fimN基因克隆到表达载体pET-28a(+)中,获得重组质粒pET28a-fimN。将此重组质粒转化受体菌BL21后,用IPTG进行诱导表达,SDS-PAGE结果显示表达蛋白分子量大小约为27 kD,与理论预期值相符。用Western-blot试验分析纯化的表达产物,结果表明,该重组蛋白能与Bb阳性血清发生特异性反应。     

兔支气管败血波氏杆菌的分离鉴定及耐药基因检测

本试验旨在了解近年来浙江省兔支气管败血波氏杆菌的感染情况及耐药状况,指导合理用药,检测细菌的耐药基因,探究其耐药机理.根据细菌形态、培养特性、生化试验,结合PCR法对分离菌株进行鉴定;K-B纸片扩散法检测细菌对18种常用抗生素的耐药率;设计耐药基因特异性引物,PCR法扩增耐药基因,并进行测序分析.结果显示,分离鉴定出2012-2014年22株兔支气管败血波氏杆菌;药敏结果显示,分离菌对青霉素G、头孢拉定、链霉素、林可霉素、克林霉素、甲氧嘧啶耐药严重,对多黏菌素B、左氟沙星、强力霉素、四环素等药物敏感,耐β-内酰胺类药物的细菌中检测到耐药基因bla_TEM.结果表明,兔支气管败血波氏杆菌是引起兔呼吸道疾病的主要病原菌,分离菌多重耐药,耐药率较高,检测到的耐药基因与耐药表型相符.     

禽波氏杆菌病原性研究及防治初探

本文介绍了禽波氏杆菌的培养特性、药物敏感性及生化特性，重点进行了禽波氏杆菌对雏鸡的致病性研究，结果证明本菌主要引起雏鸡的急性死亡，主要病变为肺脏出血，肝脏出血、边缘坏死，肾脏出血，腺胃、肌胃浆膜出血，肠道出血。不同日龄的雏鸡对禽波氏杆菌的抵抗力不同，与日龄成正相关。同时还用不同来源的8株禽波氏杆菌制成蜂胶灭活苗，并分别免疫1日龄和11日龄雏鸡，结果发现本疫苗对雏鸡的保护率低。     

The recovery of Bordetella bronchiseptica strains by means of smears from the nasal cavities of pigs

The paper presents results obtained from a study on the recovery of Bordetella bronchiseptica strains from the nasal cavities of pigs by means of tampon smears. There are several important factors influencing the reliability of recovery: restraining of animals, thorough disinfection of the snout about the nostrils prior to the taking of samples, correct method of sample collection using suitable tampons, suitable culture media for cultivation, correct cultivation method and diagnostic procedure for the isolation and identification of grown cultures.
