Ninety-eight samples of pig slurry from 54 farms were examined for the presence of salmonellas, porcine enteropathogenic strains of haemolytic Escherichia coli and mycobacteria. Salmonellas were isolated from 12 farms (22%) and enteropathogenic E. coli from 13 farms (24%). Pathogenic mycobacteria were not isolated. Salmonellas were isolated from 7 of 16 farms (44%) stocked with 'minimal disease' pigs compared with only 5 of 38 farms (13%) stocked with conventionally reared pigs. Conversely enteropathogenic coliforms were isolated from 3 of 16 farms (19%) stocked with 'minimal disease' pigs compared with 10 of 38 farms (26%) stocked with conventionally reared pigs.
对来自54个农场的98份猪粪样本进行了检测,以确定其中是否存在沙门氏菌、猪溶血性大肠杆菌肠道致病菌株和分枝杆菌。从12个农场(22%)分离出沙门氏菌,从13个农场(24%)分离出肠道致病大肠杆菌。未分离出致病性分枝杆菌。在饲养“低疾病”猪的16个农场中,有7个(44%)分离出沙门氏菌,而在传统饲养猪的38个农场中,只有5个(13%)分离出沙门氏菌。相反,在饲养“低疾病”猪的16个农场中,有3个(19%)分离出肠道致病大肠菌,而在传统饲养猪的38个农场中,有10个(26%)分离出肠道致病大肠菌。
