摘要:

为评估不同养猪场猪圈环境卫生质量,采用ANDERSEN-6级和 AGI-30(All Glass Impinger,AGI)空气微生物样品收集器分别对5个不同养猪环境中微生物气溶胶的含量与构成成分予以监测。结果表明,猪舍空气中气载需氧菌含量介于0.466×104~2.585×104 CFU•m-3,气载厌氧菌含量介于0.060×104~2.025×104 CFU•m-3,气载真菌含量介于0.265×103~1.490×103  CFU•m-3,气载内毒素含量介于0.114×103~0.533×103 EU•m-3,气载阴性菌含量介于0.014×103~0.840×103 CFU•m-3,气载阴性菌在需氧菌含量中的比例为0.30%~3.2%。需氧革兰阴性菌群主要有肠杆菌属、假单胞菌属、莫拉菌属。气载肠杆菌属中大肠杆菌、成团肠杆菌和克雷伯菌为主要菌种;气载假单胞菌属中嗜麦芽窄食单胞菌为主要菌种;莫拉菌属在各猪场环境只检测到腔隙莫拉菌。此外,只在猪场C、D分别分离到了不动杆菌菌属和根瘤菌属。通过该研究,对猪场舍环境的微生物含量及成分有了一个全面的认识,为评估环境质量奠定基础,对环境卫生控制有指导意义。

Abstract:

 In order to evaluate the hygiene quality of different swine houses,air samples from five swine farms was collected using ANDERSEN-6 and the AGI-30 (All Glass Impinger,AGI),and microbial concentration and air constituents of the breeding environment were measured.The results showed that swine airborne aerobic content ranged from 0.466×104 to 2.585×104 CFU•m-3 air,airborne anaerobic content ranged from 0.060×104  to 2.025×104 CFU•m-3 air,airborne fungal content ranged from 0.265×103 to 1.490×103 CFU•m-3 air,the airborne endotoxin content ranged from 0.114×103 to 0.533×103 EU•m-3 air,airborne gram-negative bacteria content ranged from 0.014×103 to 0.840×103 CFU•m-3 air,and on average only 0.30% to 3.2% of the total number of culturable aerobic bacteria were identified as gram-negative bacteria.In the airborne gram-negative bacterial flora the following bacterial families dominated:the Enterobacteriaceae,the Pseudomonadaceae and Morexella.Within the family of the Enterobacteriaceae the species Escherichia coliEnterobacter agglomerans and Klebsiella were predominant.Stenotrophomonas maltophilia is primary in airborne genus Pseudomonas; only Moraxella osloensis detected in each pig farm environment.In addition,Acinetobacter and Rhizobium were only strains isolated from farm C and D.The results of this study will provide more information about microbial content and composition of the breeding environment and lay the foundation for environmental quality assessment,which is significant and instructive for environment hygiene control.

Key words: swine houses environment, microbiological aerosol, bacterial flora, airborne endotoxin, airborne gram-negative bacteria
