Abstract

BACKGROUND

Foodstuffs with animal origins, particularly meat, are likely reservoirs of .

PURPOSE

An existing survey was accompanied to assess phenotypic and genotypic profiles of antibiotic resistance and genotyping of , and alleles amongst the bacteria recovered from raw meat.

METHODS

Six-hundred raw meat samples were collected and cultured. isolates were tested using disk diffusion and PCR identification of antibiotic resistance genes and genotyping.

RESULTS

Fifty-two out of 600 (8.66%) raw meat samples were contaminated with . Raw ovine meat (13.07%) had the uppermost contamination. bacteria displayed the uppermost incidence of resistance toward tetracycline (82.69%), erythromycin (80.76%), trimethoprim (65.38%), levofloxacin (63.46%), and amoxicillin (63.46%). All bacteria had at least resistance toward one antibiotic, even though incidence of resistance toward more than eight antibiotics was 28.84%. Total distribution of , and antibiotic resistance genes were 59.61%, 51.92%, 69.23%, and 65.38%, respectively. (84.61%), (76.92%), (50%), (39.13%), (38.46%), and (55.76%) were the most generally perceived alleles. (63.46%), (53.84%), (51.92%), and (42.30%) were the most generally perceived genotyping patterns. Frequency of , -, and - genotypes were 44.23%, 73.07%, and 80.76%, respectively. A total of 196 combined genotyping patterns were also perceived.

CONCLUSION

The role of raw meat, particularly ovine meat, in transmission of virulent and resistant bacteria was determined. and genotypes had the higher incidence. -, and bacteria had the higher distribution. Supplementary surveys are compulsory to originate momentous relations between distribution of genotypes, antibiotic resistance, and antibiotic resistance genes.

摘要

背景

动物性食品,尤其是肉类,可能是……的储存宿主。

目的

开展一项现有调查,以评估从生肉中分离出的……细菌的抗生素耐药性表型和基因型特征以及……、……和……等位基因的基因分型。

方法

收集600份生肉样本并进行培养。对分离菌株进行纸片扩散法检测以及抗生素耐药基因的PCR鉴定和基因分型。

结果

600份生肉样本中有52份(8.66%)被……污染。生羊肉(13.07%)的污染率最高。……细菌对四环素(82.69%)、红霉素(80.76%)、甲氧苄啶(65.38%)、左氧氟沙星(63.46%)和阿莫西林(63.46%)的耐药率最高。所有……细菌至少对一种抗生素耐药,尽管对八种以上抗生素的耐药率为28.84%。……、……、……和……抗生素耐药基因的总分布分别为59.61%、51.92%、69.23%和65.38%。……(84.61%)、……(76.92%)、……(50%)、……(39.13%)、……(38.46%)和……(55.76%)是最常见的等位基因。……(63.46%)、……(53.84%)、……(51.92%)和……(42.30%)是最常见的基因分型模式。……、……和……基因型的频率分别为44.23%、73.07%和80.76%。还发现了总共196种组合基因分型模式。

结论

确定了生肉,尤其是羊肉,在传播有毒和耐药……细菌中的作用。……和……基因型的发生率较高。……、……和……细菌的分布较广。必须进行补充调查,以确定基因型分布、抗生素耐药性和抗生素耐药基因之间的重要关系。
