摘要

背景:弯曲杆菌是一种重要的食源性细菌,因为受污染的禽肉消费。目的:研究从生禽肉样品中分离的弯曲杆菌的发病率和耐药情况。材料与方法:采集695份禽肉样品,采用培养技术进行鉴定。采用聚合酶链反应(PCR)鉴定细菌种类。采用纸片扩散法(DDM)进行耐药性评价。结果:弯曲杆菌的污染率为44.75%,其中野鸭(84%)、雁(83.33%)、白骨顶(78.26%)、鸡(67.78%)和野鸡(66.66%)的污染率较高。空肠弯曲菌和大肠杆菌分别占84.24%和15.76%。空肠梭菌在鹌鹑(95.45%)、鹌鹑(95%)、野鸡(92.31%)和野鸭(90.48%)肉类样品中的感染率最高。大肠杆菌在火鸡(52.63%)和野鸡(22.22%)中感染率最高。其中,空肠梭菌对四环素(76.34%)、萘啶酸(65.65%)、环丙沙星(58.78%)、恩诺沙星(39.69%)和氨苄西林(38.55%)的耐药性最高。大肠杆菌对萘啶酸(48.99%)、环丙沙星(40.82%)和恩诺沙星(38.78%)的耐药性最高。结论:禽肉是弯曲杆菌的主要传播源,尤其是鹧鸪、鹌鹑、野鸡、火鸡和野禽。此外,空肠梭菌的发病率和耐药性也较高。正确烹调禽肉和监测抗生素处方可减少耐药弯曲杆菌在禽肉中的发生。

Incidence and Antibiotic Resistance Properties of Campylobacter Species Isolated From Poultry Meat
Background: F Campylobacter species are imperative foodborne bacteria because of the contaminated poultry meat consumption. Objectives: This study was conducted to recognize the incidence and antimicrobial resistance profile of Campylobacter species recovered from raw poultry meat samples. Materials and Methods: A total of 695 poultry meat samples were collected and assessed by culture technique. Bacterial species were identified by polymerase chain reaction (PCR). Antimicrobial resistance was assessed by disk diffusion method (DDM). Results: The contamination rate of samples with Campylobacter spp. was 44.75% with higher contamination rate of wild duck (84%), wild goose (83.33%), coot (78.26%), chicken (67.78%), and wild pheasant (66.66%), respectively. Campylobacter jejuni and C. coli bacteria were found in 84.24% and 15.76% of Campylobacter spp., respectively. The highest incidence of C. jejuni was obtained in partridge (95.45%), quail (95%), pheasant (92.31%), and wild duck (90.48%) meat samples, respectively. The highest incidence of C. coli was found in turkey (52.63%) and wild pheasant (22.22%) meat samples, respectively. Moreover, C. jejuni had the highest resistance to tetracycline (76.34%), nalidixic acid (65.65%), ciprofloxacin (58.78%), enrofloxacin (39.69%), and ampicillin (38.55%), respectively. C. coli had the highest resistance to nalidixic acid (48.99%), ciprofloxacin (40.82%), and enrofloxacin (38.78%), respectively. Conclusion: Poultry meat, particularly partridge, quail, pheasant, turkey, and wild avian are the main sources of Campylobacter transmission. Furthermore, higher incidence and antibiotic resistance of C. jejuni was found. Proper cooking of poultry meat and monitoring the antibiotic prescription can lessen the occurrence of antibiotic-resistant Campylobacter spp. in poultry meat.
