摘　　要：为掌握贵州省规模化养猪场主要疫病发生发展与环境微生物的关系,通过细菌计数与分离鉴定对2个规模化养猪场周围环境的空气、饮用水、污水、粪便和土壤样本细菌总数和优势细菌进行了监测。结果表明,猪场空气、饮用水、污水、粪便和土壤的细菌总数分别为0.215×104～24.9×104 CFU/m3、0.15×102～10×102CFU/m3、2.84×107～79.30×107 CFU/m3、8.96×106～295×106 CFU/m3和0.213×105～14.5×105CFU/m3;优势菌群为葡萄球菌、链球菌、大肠埃希氏菌、沙门氏菌、芽孢杆菌和志贺氏菌等。Total bacterial count and dominant bacterial flora of air,drinking water,sewage,dung and soil samples from the surrounding environment of two scale pig farms were monitored by bacterial counting,isolation and identification to master the relationship between occurrence and development of main diseases and environmental microbial in the scale pig farm in Guizhou.The results showed that total bacterial count of air,drinking water,sewage,dung and soil samples from the surrounding environment of two scale pig farms was 0.215×104～24.9×104CFU/m3,0.15×102～10×102CFU/m3,2.84×107～79.30×107CFU/m3,8.96×106～295×106CFU/m3 and 0.213×105～14.5×105CFU/m3 and the dominant bacterial flora was Staphylococcus,Streptococcus,Escherichia coli,Salmonella,Bacillus and Shigella separately.
