合肥地区类志贺邻单胞菌的动物贮存宿主调查

An Investigation of Animal Hosts for Plesiomonas Shigelloides in Hefei Area,Anhui Province

为探讨合肥地区类志贺邻单胞菌的动物贮存宿主，采用二次增菌分离培养法，对１５种２２８份标本进行检测，结果１２处３６份样品检出此菌，总阳性检出率为１５．７９％，鱼类、观赏水禽、家鸭、猪和清摘工，阳性检出率分别为２３．２９％、１７．８６％、１３．０４％、６．６７％和１０％，表明该菌具有广泛动物贮存宿主，尤其是淡水鱼类，同时对３６株阳性菌的血清分群，其中１７株可分群，分群率为４７．２２％，共分布于７个血清型。

gut content samples from 15 animals species including healthy human were examined bacteriologically with cultivation. 36 samples from 12 species were found to have Plesionmonas Shigelloides,with postive rates 15.79%.The carrier rates among fishes,ornamental fowls,domestic ducks,pigs and healthy human were 23.29%、17.86%、13.04%、6.67% and 10% respectively.The study exhibited that natural hosts of Plesiomonas Shigelloides were widespread and main source of infection hid in fishes.In the 36 samples,17 strains had been grouped sucessfully,with grouping rate 47.22% and distributed in the 7 serum groups.The common group from human and animal sources were O 19 .
