| Abstract: |
| In order to provide base data on the pollution status of methicillin-resistant Staphylococcus aureus(MRSA) in poultry farms and reveal its transmission between humans and livestock, in this research, an FA-Ⅰ sampler was used to collect total bacteria, Staphylococcus aureus, and methicillin-resistant MRSA in the air layer, and feces samples were collected at the same time. In order to analyze the variation trend and its possible influencing factors as a function of time(days), the concentrations of bacteria in the air and the corresponding feces were examined. The results showed that the average concentrations of MRSA in the air and feces were(4.31×102±4.56×102)CFU·m-3 and (3.37×104±4.83×104)CFU·m-3, respectively, with ratios in the Staphylococcus aureus of 41.99%±26.99% and 22.11%±20.06%. The total bacteria concentration increased linearly with increasing age in both the air and feces samples. The concentration of Staphylococcus aureus and MRSA in the air increased with time and was affected by both temperature and particle concentration. The variation of MRSA concentration in PM2.5 was similar to that of total MRSA in the air. The average concentration of the PM2.5 portion was(1.51×102±1.7×102)CFU·m-3, which accounted for 38.13%±20.17% of the total MRSA. |
