福建省流行病研究所等单位,近两年来对小肠结肠炎耶氏菌病进行了调查研究,发现该病在我省的分布相当广泛,人畜均有发病。目前已从病人、猪、鼠和鸡分离出200余株小肠结肠炎耶氏菌,经过鉴定多数属于生物3型和血清0:3型或与0:3型有共同抗原成分;少数为生物4型和血清0:9型。检出耶氏菌的范围已有14个地区和9个县市,为腹泻病的主要致病菌之一。此外还从病人和猪的粪便分离出耶氏菌噬菌体。对分离的耶氏菌株从多方面进行了致病性研究。
Fujian Institute of Epidemiology and other units, in the past two years, Yersinia enterocolitis disease were investigated and found that the distribution of the disease in our province is quite extensive, both human and animal disease. At present, more than 200 Y. enterocolitica strains have been isolated from patients, pigs, mice and chickens. Most of the identified strains belong to the biological type 3 and the serum type 0: 3 or have common antigenic components with the type 0: 3. A few are biological 4 Type and serum 0: 9 type. The detection of Yersinia has 14 areas and 9 counties, which is one of the major pathogens of diarrhea. In addition, Yersinia phages are also isolated from the patient’s and pig’s faeces. Pathogenicity studies were conducted on isolated Yarrowia strains from various aspects.
