| Abstract: |
| Bioaerosols emitted from confined animal feeding operations may pose health risks to workers and animals. In this study, content of culturable airborne bacteria was detected in the atmospheric environments of both layer and broiler houses. In addition, corresponding microbial communities were analyzed using denatured gradient gel electrophoresis(DGGE). Results indicated that both content and microbial diversity of airborne bacteria in the layer houses were higher than those in the broiler ones. Under the same farming mode, microbial diversity decreased with increasing age of poultry. The main bacteria in atmospheric environment of confined poultry houses were Bacteroidetes,Proteobacteria and Firmicutes. Enterobacter and Escherichia were the predominant genus of airborne bacteria in layer and broiler houses, respectively. |
