本文对某部军事作业坑道内空气中细菌总数及致病性链球菌调查结果:两项指标超标率分别为82％、35.29％,平均超标2.47倍和27.62倍;通道及大厅內人员走动少、气温低且湿度较大的方位细菌总数及致病性链球菌生长少、繁殖慢。各工作间及电机房、风机房等人员活动多、气温较温暖,细菌总数及溶血型链球菌生长多、繁殖快;实验室还发现在普通营养琼脂及羊血琼脂培养基上同时有多种致病菌生长。在条件适宜时,有一定的致病性。
In this paper, the number of bacteria in the air and pathogenic streptococcus in the tunnel of a military operation were investigated. The exceeding rates of the two indexes were 82% and 35.29% respectively, with an average of 2.47 times and 27.62 times respectively. Low temperature and humidity of the total number of azimuthal bacteria and pathogenic Streptococcus less growth, reproduction slow. The workroom and the motor room, the wind room and other personnel activities, the temperature is warmer, the total number of bacteria and hemolytic streptococcus growth and rapid reproductive; laboratory also found in ordinary nutrient agar and sheep blood agar medium at the same time a variety of Pathogen growth. When conditions are right, there is a certain pathogenicity.
