猪场环境中主要病原菌耐药性分析

对贵州省6个规模养猪场圈舍内外空气、污水、粪便和土壤样本进行细茵总数测定,并对不同环境样本中分离的大肠杆菌、沙门氏菌、葡萄球菌和链球菌进行药敏试验,以了解规模猪场环境细菌污染状况及主要病原菌的耐药性.结果显示,猪场环境细菌污染严重,其总教均一定程度地超出国家规定的卫生标准.其中,粪便样本含菌量最高,其次为污水、土壤样本...

Monitoring and Drug Tolerance Analysis of Bacteria in Scaled Pig Farm

In the present study, total number and drug tolerance of bacteria （ Escherichia, Salmonella, Staphylococcus, Streptococcus） in air, sewage water, faecal and soil sample were investigated among six-scale pig farms. The result showed that bacteria amount in faecal ranked the first, followed by that in sewage water and soil, and the amount from abovementioned surrounding sites were higher than those in the air （0.01 〈 P≤ 0. 05 ）. Drug sensitive test proved that no remarkable effect of antibiotics on Penicillin, Tetracycline, and Lincomyeinthe was obtained. The tolerance rate of bacteria from sewage water and faecal were higher than that from the air. Therefore, the numbers of bacteria exceeded the requirement of national regulation for livestock and poultry farms, and the bacteria existed wide-spectrum drug tolerance.
