The Size Distrition and Health Risk Assessment of Microbe Bacterial Aerosol in Livestock and Poultry House
摘要
Abstract
In order to determine the size distribution of aerodynamic particles of bacterial microbe in livestock and poultry house,and to evaluate the potential health threats,air samples were collected systematically at fixed points by Andersen six stages air sampler,using blood agar medium,Sabouraud agar medium and Gause’s synthetic agar medium no.1 in chicken,pig and cow houses,and tested and analyzed for microbe aerosol size distribution. The re-sults showed that bacterial aerosol in livestock and poultry houses were mostly distributed in stage I. Bacterial aerosol appeared skew distribution in chicken house. The second peak appeared in stageⅢ andⅣ separately in cow and pig houses. The inhalable particles carrying bacteria in chicken house accounted the maximum proportion. The highest dis-tribution peak of fungus aerosol and actinomycetes aerosol appeared in stageⅣ. The ration of fungi and actionomycetes carried by inhalable particles were significantly higher than bacteria(P<0.05). The microbe aerosol size distribution proportions were basically identical at all stages. About 6.1×105CFU、4.7×104CFU and 3.6×104CFU airborne aerobic bacteria in livestock and poultry house could be inhaled into the small bronchia or even directly invaded into alveoli, posing potential threats to human and animals health.关键词
