Abstract

This study on the microbiology of chicken assessed a total of 97 live birds from three selected farms and 87 carcasses/chicken parts from two supermarkets, two open markets and one wholesale outlet (cold store) in the Accra metropolis. Campylobacter spp. were isolated from 14 (14.4%) gut contents of live birds from three farms. None of the frozen birds were positive for Campylobacter spp. These isolates were sensitive to most common antibiotics but not to ampicillin and tetracyclines. Salmonella spp. were isolated from 7 (7.2%) gut contents and 13 (6.8%) carcasses and were resistant to erythromycin. cefotiam, penicillin, ampicillin and cefadroxil. Samonella spp. had varied susceptibilities to nalidixic acid, chloramphenicol and minocyclin. No Shigella spp. was isolated from any of the live birds but 6 (6.9%) of imported chicken samples from the cold store and two markets were positive. Fosfomycin and chloramphenicol were the only antibiotics effective against these isolates. Twelve different Escherichia coli serovars were identified from the total of 21 positive samples. These, in order of magnitude isolated, are E. coli 0158 (14.3%), 0125 (14.3%), 025 (9.5%), 028ac (9.5%), 0159 (9.5%). 015 (9.5%), 0126 (9.5%), 063 (4.8%), 0143 (4.8%), 026 (4.8%), 078 (4.8%), 0164 (4.8%). Cefadroxil, ampicillin, penicillin, cefotiam, tetracycline and erythromycin were ineffective against all strains of E. coli isolated. Minocyclin was effective against all strains with the exception of E. coli 0159, 025, 0164 and 063, which were moderately susceptible. All strains with exception of E. coli 0164 were susceptible to fosfomycin. Nalidixic acid, chloramphenicol, kanamaycin, ceftrioxone and amoxycillin all showed varied effectiveness against the strains isolated. It is concluded that imported and locally produced chicken is a potential source of multiple-antibiotic-resistant enteropathogenic bacteria. Measures to improve the microbial quality of chicken are discussed.

摘要

这项关于鸡肉微生物学的研究评估了来自阿克拉大都会三个选定农场的97只活禽以及来自两家超市、两个露天市场和一个批发店(冷藏库)的87具鸡胴体/鸡肉部分。从三个农场的14只(14.4%)活禽的肠道内容物中分离出弯曲杆菌属。冷冻禽中没有弯曲杆菌属呈阳性。这些分离株对大多数常见抗生素敏感,但对氨苄青霉素和四环素不敏感。从7只(7.2%)肠道内容物和13具(6.8%)鸡胴体中分离出沙门氏菌属,且它们对红霉素、头孢替安、青霉素、氨苄青霉素和头孢羟氨苄耐药。沙门氏菌属对萘啶酸、氯霉素和米诺环素的敏感性各不相同。从任何活禽中均未分离出志贺氏菌属,但冷藏库和两个市场的6份(6.9%)进口鸡肉样本呈阳性。磷霉素和氯霉素是仅对这些分离株有效的抗生素。从总共21份阳性样本中鉴定出12种不同的大肠杆菌血清型。按分离数量多少依次为大肠杆菌O158(14.3%)、O125(14.3%)、O25(9.5%)、O28ac(9.5%)、O159(9.5%)、O15(9.5%)、O126(9.5%)、O63(4.8%)、O143(4.8%)、O26(4.8%)、O78(4.8%)、O164(4.8%)。头孢羟氨苄、氨苄青霉素、青霉素、头孢替安、四环素和红霉素对所有分离出的大肠杆菌菌株均无效。米诺环素对所有菌株有效,但大肠杆菌O159、O25、O164和O63为中度敏感。除大肠杆菌O16外,所有菌株对磷霉素敏感。萘啶酸、氯霉素、卡那霉素、头孢曲松和阿莫西林对分离出的菌株均显示出不同程度的有效性。结论是进口和本地生产的鸡肉是多重耐药性肠道病原菌的潜在来源。文中讨论了提高鸡肉微生物质量 的措施。
