| 摘 要： | 为分析家禽屠宰场存在的水体、地面和与鸡肉接触的屠宰器械表面的菌群结构及其耐药基因携带状况,在浙江省某大型屠宰场的挂禽间、宰杀沥血间、浸烫间、脱毛间、净膛间区域取存在水体,用无菌纱布擦拭各区域的地面和器械表面采集微生物,采用基于16S rRNA基因V3-V4的Illumina 高通量测序方法分析其菌群结构多样性,并用PCR对细菌的9大类24种耐药基因进行检测分析。结果表明,屠宰场不同区域水体、地面和屠宰器械表面微生物均以变形菌门(Proteobacteria)、厚壁菌门(Firmicutes)和放线菌门(Actinobacteria)为主,其相对丰度分别为27.55%~88.99%、3.45%~59.78%和4.35%~31.78%;优势菌属为不动杆菌属(Acinetobacter)、嗜冷杆菌属(Psychrobacter)、栖热菌属(Thermus)、假单胞菌属(Pseudomonas)和希瓦氏菌属(Shewanella),约占总类群46%。共检测到21种耐药基因分布在这些样品中,其中sulⅠ、sulⅡ和qnrS的检出率为100%,blaTEM、tetB和aadA1的检出率为94.4%,floR和mecC的检出率为88.9%。由此反映出屠宰场不同区域的水体、地面和屠宰器械表面存在一些条件性致病菌和腐败菌,且携带的耐药基因种类较多。 |

| Abstract: | The aim of this study is to investigate the microbial community structure and resistance genes on water, surface of floor and slaughtering equipment. The water and the bacteria collected on floor and surface of slaughtering equipment by sterile gauze swab were sampled in hanging, slaughtering, scalding, dehairing, eviscerating rooms of a large-scale poultry slaughterhouse in Zhejiang Province. The microbial community structure was analyzed based on 16S rRNA V3-V4 by Illumina Hiseq 2500, while the nine major categories of 24 resistance genes were tested by PCR method. The results showed that Proteobacteria, Firmicutes and Actinobacteria were the predominant phyla on water and the surface of floor and slaughtering equipment in the different areas of the slaughterhouse, their relative abundance were 27.55%-88.99%, 3.45%-59.78%, 4.35%-31.78%, respectively. The dominant genera included Acinetobacter, Psychrobacter, Thermus, Pseudomonas and Shewanella, accounting for 46% of the total taxa. The drug resistance gene detection rate of sulⅠ, sulⅡ and qnrS was 100%, while blaTEM, tetB and aadA1 was 94.4%, and floR and mecC was 88.9%. It was concluded that there were some conditional pathogenic bacteria and spoilage bacteria with many kinds of bacterial resistance genes on water and the surface of ground and slaughtering equipments in different areas of the slaughterhouse. |
