| 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. |
