Spread of S. aureus Aerosols Carrying Antibiotic-Resistant Genes (Including MRSA) from Chicken Farms to Their Neighborhood Residents Environment
There is a rather limited understanding concerning the antibiotic-resistance of the airborne S.aureus and the transmission of the antibiotic-resistant genes it carries Therefore,we isolated 149 S.aureus strains from the samples collected from the feces,the indoor air and the outdoor air of 6 chicken farms,and performed the research on them with 15 types of antibiotics and the REP-PCR trace identification.The 100%homologous strains were selected to conduct the research on the carrying and transmission status of the antibiotic-resistant genes.The results revealed that 5.37% strains(8/149) were resistant to methicillins (MRSA),and 94% strains (140/149) were resistant to compound sulfamethoxazole,etc.In addition,these strains displayed a resistance to multiple antibiotics (4,5 or 6 types) and there were also 3 strains resistant to 9 antibiotics.the strains with the same REP-PCR trace identification result carried the same type of antibiotic-resistant genes.The results showed that airborne transmission not only causes the spread of epidemic diseases but also exerts threats to the public health of a community.
