环卫工人鼻粘膜细菌检出率调查研究

本文检验了垃圾清理工人鼻粘膜含菌分布,与对照人群比较,其中细菌总数相差不显著;溶血菌的检出率环卫工人高于对照人群,相差非常显著;并从环卫工人鼻粘膜分离出了致病的肺炎双球菌和大量存在于外环境中的蜡样芽孢杆菌。表明环卫作业环境对环卫工人的健康带来一定的影响。

Investigation of Detective Rates of Bacteria on Nasal Mucous Membranes of Environmental Health Workers

The bacteria distribution on nasal mucous membranes of refuse cleaning workers was examined. There was no significant difference as to the plate count between environmental health workers and the control group. Whereas the detective rate of haemolytic bacteria was significantly higher in the former than in the latter. Pathogenic Streptococcus pneumoniae and Bacillus cereus abundantIy existing in ambient environment were also isolated from the nasal mucous membranes of the workers. It was shown that the working environment would bring about certain influence on the health of environmental health workers.
