AIM
Antimicrobial resistance is a global health threat. This study investigated the prevalence of in imported 1-day-old chicks, ducklings, and turkey poults.
MATERIALS AND METHODS
The liver, heart, lungs, and yolk sacs of 148 imported batches of 1-day-old flocks (chicks, 45; ducklings, 63; and turkey poults, 40) were bacteriologically examined for the presence of .
RESULTS
We isolated 38 strains from 13.5%, 6.7%, and 5.4% of imported batches of 1-day-old chicks, ducklings, and turkey poults, respectively. They were serotyped as O91, O125, O145, O78, O44, O36, O169, O124, O15, O26, and untyped in the imported chicks; O91, O119, O145, O15, O169, and untyped in the imported ducklings; and O78, O28, O29, O168, O125, O158, and O115 in the imported turkey poults. The isolates were investigated for antibiotic resistance against 16 antibiotics using the disk diffusion method and were found resistant to cefotaxime (60.5%), nalidixic acid (44.7%), tetracycline (44.7%), and trimethoprim-sulfamethoxazole (42.1%). The distribution of extended-spectrum β-lactamase (ESBL) and β-lactamase genes was (52.6%), (28.9%), (39.5%), (13.1%), and (28.9%).
CONCLUSION
Imported 1-day-old poultry flocks may be a potential source for the dissemination of antibiotic-resistant and the ESBL genes in poultry production.
目的
抗菌素耐药性是对全球健康的一种威胁。本研究调查了进口1日龄雏鸡、雏鸭和小火鸡中[具体细菌名称未给出]的流行情况。
材料与方法
对148批进口的1日龄鸡群（雏鸡45批、雏鸭63批和小火鸡40批）的肝脏、心脏、肺和卵黄囊进行细菌学检查，以检测[具体细菌名称未给出]的存在情况。
结果
我们分别从13.5%的进口1日龄雏鸡、6.7%的进口1日龄雏鸭和5.4%的进口1日龄小火鸡批次中分离出38株[具体细菌名称未给出]菌株。在进口雏鸡中，它们的血清型为O91、O125、O145、O78、O44、O36、O169、O124、O15、O26以及未分型；在进口雏鸭中为O91、O119、O145、O15、O169以及未分型；在进口小火鸡中为O78、O28、O29、O168、O125、O158和O115。使用纸片扩散法对分离出的[具体细菌名称未给出]菌株进行了针对16种抗生素的耐药性调查，发现它们对头孢噻肟（60.5%）、萘啶酸（44.7%）、四环素（44.7%）和甲氧苄啶 - 磺胺甲恶唑（42.1%）耐药。超广谱β - 内酰胺酶（ESBL）和[具体β - 内酰胺酶基因名称未给出]基因的分布情况为[具体基因名称未给出]（52.6%）、[具体基因名称未给出]（%）、[具体基因名称未给出]（39.5%）、[具体基因名称未给出]（13.1%）和[具体基因名称未给出]（28.9%）。
结论
进口1日龄家禽群体可能是家禽生产中耐抗生素[具体细菌名称未给出]和ESBL基因传播的一个潜在来源。
