We looked for Salmonella in all 278 apparently healthy pigs slaughtered between September 2004 and May 2005 at the only pig-slaughtering slaughterhouse in Addis Ababa, Ethiopia. We used standard methods and tested caecal contents, mesenteric lymph nodes, and carcass swabs from each pig (missing only one carcass swab). Of the 278 pigs, 120 (43%) were positive; of the 833 samples 173 (21%) were positive. Thirty-three percent of the isolates were multi-resistant (including 46/48 isolates of S. Hadar, but none of the 39 isolates of S. Eastbourne or of the 37 of S. Saintpaul). Resistance to streptomycin (32.4%), tetracycline (31.8%) and nitrofurantoin (27.2%) was relatively high. The most common pattern of MDR observed was to nitrofurantoin, streptomycin and tetracycline (Resistance type NitStrTet). Our results indicate that salmonellae are prevalent in pigs slaughtered at Addis Ababa abattoir and a large proportion of the isolates were multi-drug resistant.
我们在2004年9月至2005年5月期间于埃塞俄比亚亚的斯亚贝巴唯一的生猪屠宰场宰杀的278头看似健康的猪中检测沙门氏菌。我们采用标准方法，检测了每头猪的盲肠内容物、肠系膜淋巴结和胴体拭子（仅缺失一份胴体拭子）。在这278头猪中，120头（43%）呈阳性；在833份样本中，173份（21%）呈阳性。33%的分离株具有多重耐药性（包括48株哈达尔沙门氏菌中的46株，但伊斯特本沙门氏菌的39株分离株和圣保罗沙门氏菌的37株分离株均无耐药性）。对链霉素（32.4%）、四环素（31.8%）和呋喃妥因（27.2%）的耐药性相对较高。观察到的最常见多重耐药模式是对呋喃妥因、链霉素和四环素耐药（耐药类型为NitStrTet）。我们的结果表明，沙门氏菌在亚的斯亚贝巴屠宰场宰杀的猪中普遍存在，且很大一部分分离株具有多重耐药性。
