| 摘 要： | 为了给北京地区不同类型养鸡场空气环境中生物气溶胶的危害评价提供基础数据,对蛋鸡和肉鸡两种养殖方式下,鸡舍内外空气环境中生物气溶胶的浓度和粒径分布进行检测,并对大肠菌群和抗生素抗性菌进行了分析。结果表明,北京郊区(县)蛋鸡舍内,所调查的五种生物气溶胶(细菌、真菌、大肠菌群、四环素和红霉素抗性菌)浓度高于同地区肉鸡舍(P<0.05)。蛋鸡舍内空气中约50%的细菌气溶胶分别具有四环素和红霉素抗性;大肠菌群、四环素抗性大肠菌群和红霉素抗性大肠菌群的平均浓度分别为7.32×103、2.87×103CFU·m-3和3.31×103CFU·m-3。两种养殖方式下细菌和真菌气溶胶粒径分布规律有所差异,导致其在细颗粒物中所占比例不同。

| Abstract: | The objective of this study was to examine concentrations, size distribution and antimicrobial resistance bacteria(ARB) of bioaerosols from layer and broiler buildings in the suburbs of Beijing. The results indicated that the concentrations of investigated bioaerosols(airborne bacteria, airborne fungi, airborne coliform bacteria and antimicrobial resistance bacteria) in the air environment of the layer were significantly higher than those of the broiler(P<0.05). The percentages of airborne tetracycline-resistant bacteria and erythromycin-resistant bacteria were about 50% in both types of chicken house. The concentrations of airborne coliform bacteria, tetracycline-resistant coliform bacteria, and erythromycin-resistant coliform bacteria in the air of the layer were 7.32×103, 2.87×103 CFU·m-3 and 3.31×103 CFU·m-3, respectively. The size distribution characteristics of both airborne bacteria and fungi in the layer were different from those of the broiler, leading to a difference in the percentages of bioaerosols attached to fine particles. This study provides basic data for evaluation of potential health risk from bioaerosols to both livestock and human beings in poultry environment. |
