To characterize antibiotic resistant Escherichia coli and Salmonella isolates in rooks wintering in the Czech Republic.
Three hundred and sixty-three faeces samples from rooks were examined for antibiotic resistant Escherichia coli and Salmonella. Altogether 13.7%E. coli isolates were resistant to antimicrobial agents tested. The dominant type of resistance was to tetracycline. Resistant E. coli isolates were examined for antibiotic resistance genes and class 1 integrons. Five of 29 antibiotic resistant isolates possessed the int1 gene. Nine Salmonella isolates (2.5%) were found in rook faeces. All the isolates belonged to serotype Salmonella enterica serovar Enteritidis phage type PT8 and PT23.
The study suggests that rooks can be infected by antibiotic resistant E. coli and Salmonella isolates, probably reflecting the presence of such isolates in their sources of food and/or water in the environment.
Rooks can serve as reservoirs and vectors of antibiotic resistant E. coli and Salmonella isolates and potentially transmit these isolates over long distances.
对在捷克共和国越冬的白嘴鸦体内的耐抗生素大肠杆菌和沙门氏菌分离株进行特征分析。
对363份白嘴鸦粪便样本进行了耐抗生素大肠杆菌和沙门氏菌检测。总共13.7%的大肠杆菌分离株对所检测的抗菌剂具有抗性。主要的耐药类型是对四环素耐药。对耐药大肠杆菌分离株进行了抗生素耐药基因和1类整合子检测。29株耐抗生素分离株中有5株携带int1基因。在白嘴鸦粪便中发现了9株沙门氏菌分离株（2.5%）。所有分离株均属于肠炎沙门氏菌肠炎亚种噬菌体分型PT8和PT23。
该研究表明白嘴鸦可能会被耐抗生素大肠杆菌和沙门氏菌分离株感染，这可能反映出这些分离株存在于其环境中的食物和/或水源中。
白嘴鸦可作为耐抗生素大肠杆菌和沙门氏菌分离株的储存宿主和传播媒介，并有可能远距离传播这些分离株。
