A cross-sectional investigation was conducted concerning prevalence, antimicrobial resistance, multidrug resistance patterns, and serovar diversity of Salmonella in chicken meat sold at retail in Yangon, Myanmar. The 141 chicken meat samples were collected at 141 retail markets in the Yangon Region, Myanmar, 1 November 2014 to 31 March 2015. Information on hygienic practices (potential risk factors) was retrieved via checklists. Salmonella was isolated and identified according to International Organization for Standardization methods (ISO 6579:2002) with minor modifications. Twelve antimicrobial agents belonging to eight pharmacological groups were used for antimicrobial susceptibility testing (disk diffusion method). Salmonella was recovered from 138 (97.9%) of the 141 samples. The isolates were most frequently resistant to trimethoprim-sulfamethoxazole (70.3% of isolates), tetracycline (54.3%), streptomycin (49.3%), and ampicillin (47.1%). Resistance was also found to chloramphenicol (29.7%), amoxicillin-clavulanic acid (17.4%), ciprofloxacin (9.4%), tobramycin (8.7%), gentamicin (8%), cefazolin (7.2%), lincomycin-spectinomycin (5.8%), and norfloxacin (0.7%). Among the 138 Salmonella isolates, 72 (52.2%) were resistant to three or more antimicrobial agents. Twenty-four serovars were identified among the 138 Salmonella-positive samples; serovars Albany, Kentucky, Braenderup, and Indiana were found in 38, 11, 10, and 8% of samples, respectively. None of the potential risk factors were significantly related to Salmonella contamination of chicken carcasses. This study provides new information regarding prevalence and antimicrobial resistance and Salmonella serovar diversity in retail markets in Yangon, Myanmar.
对缅甸仰光零售的鸡肉中沙门氏菌的流行情况、抗菌药物耐药性、多重耐药模式和血清型多样性进行了横断面调查。2014年11月1日至2015年3月31日期间，在缅甸仰光地区的141个零售市场采集了141份鸡肉样本。通过清单获取了卫生操作（潜在风险因素）方面的信息。沙门氏菌的分离和鉴定按照国际标准化组织方法（ISO 6579:2002）进行了微小修改。使用属于八个药理学组的12种抗菌药物进行抗菌药敏试验（纸片扩散法）。141份样本中有138份（97.9%）检出沙门氏菌。分离株最常对甲氧苄啶-磺胺甲恶唑（70.3%的分离株）、四环素（54.3%）、链霉素（49.3%）和氨苄西林（47.1%）耐药。还发现对氯霉素（29.7%）、阿莫西林-克拉维酸（17.4%）、环丙沙星（9.4%）、妥布霉素（8.7%）、庆大霉素（8%）、头孢唑林（7.2%）、林可霉素-大观霉素（5.8%）和诺氟沙星（0.7%）耐药。在138株沙门氏菌分离株中，72株（52.2%）对三种或更多种抗菌药物耐药。在138份沙门氏菌阳性样本中鉴定出24种血清型；分别在38%、11%、10%和8%的样本中发现了奥尔巴尼、肯塔基、布伦德鲁普和印第安纳血清型。没有一个潜在风险因素与鸡胴体的沙门氏菌污染显著相关。本研究提供了有关缅甸仰光零售市场沙门氏菌流行情况、抗菌药物耐药性和血清型多样性的新信息。
