1981年11月至1982年9月间，作者等在福建省南部选三个养猪场，调查不同季节猪中小肠结肠炎耶氏菌的带菌动态。
两个养猪场仅在冬、春两季有检出，阳检率在春季显著提高，分别从1.69%与0.79%升至28.57%与10.14%，表明该两猪群中出现过较严重的流行。福建省人群耶氏菌病亦在其时流行。另一养猪场四季皆有检出，阳检率稽留在1.52%与2.87%间，仅为散在发生。猪群间流行强度似与饲养方式有重要关系，严重流行的猪场，猪多为放养或定期放养，猪活动范围大，感染机会多；散在发生猪场则为圈养，猪活动限制在极小范围内，感染机会少。 |
| English Abstract: |
| The seasonal variation in the carriage rates of Yersinia enterocolitica (Ye) in pig fed in 3 pig farms in the south of Fujian Province was investigated throughout the 4 seasons between Nov. 1981 and Sep. 1982. In 2 of the pig farms, Ye strains were only isolated in winter and spring, and the carriage rates were significantly raised in spring from 1.69% and 0.79% to 28.57% and 10.4% respectively, which showed that serious outbreaks of Ye occurred. And the prevalence among human beings in Fujian Province happened in the same seasons too. In the other pig farm, Ye strains were isolated throughout the 4 seasons, and the carriage rates remained within a range of 1.52 to 2.87%. which showed that only sporadic infections occurred. A significant relation may exist between the seriousness of prevalence in pigsand the forms of feeding, i.e., the wider the feeding-ground, the higher the infection. |
