摘要

Salmonella contamination of chickens introduced to farms was examined. The feces in the litter of chick boxes and on the chicken transport vehicles were tested. Salmonella was detected from ten boxes and four vehicles from a total of 94 introduced chicken flocks. Of the Salmonella detected, one type from litter material was Salmonella Enteritidis (SE) and others were S. Montevideo, S. Worthington, S. Senftenberg, S. Hadar, S. Infantis, S. Agona, S. Havana, O 7, O 8, O 13 and 035 serotypes. Chickens from positive flocks were reexamined after introduction. Salmonellea was reisolated from seven out of eight chick flocks and two out of four grower flocks. In the SE-positive flock, 32 out of 5,250 chicks died. SE was isolated from remnant yolk of all five dead chicks examined. Histopasologically small necrotic foci in the liver and epicarditis were observed. This contaminated chick flock was taken back by the breeder farm. The contaminated chicken house was thoroughly disinfected to prevent the spread of SE and has been kept clean since. DHL and MLCB agar plate cultur media were compared to determine the efficiency in isolating Salmonella. Of the 94 flocks examined, Salmonella in 8 flocks was detected by both DHL and MLCB, in six flocks by MLCB alone and 0 flock by DHL alone.

Havana，O 7， O 8，O 13和035血清型。在引言后重新审视来自正羊群的鸡。 Salmonellea从八个小鸡群中的七个重新坐出，并从四个种植者羊群中的两个。在SE阳性羊群中，5250只小鸡中的32个死亡。 SE从所有五只死雏鸡的残余蛋黄中分离出来。观察到肝脏和心膜膜炎中的组织学上小坏死病灶。这种受污染的小鸡群被饲养场被送回。受污染的鸡舍被彻底消毒，以防止SE的扩散，并以来一直保持清洁。比较DHL和MLCB琼脂平板培养基，以确定分离沙门氏菌的效率。在94群羊群中，DHL和MLCB检测到8个羊的沙门氏菌，单独使用MLCB的六个羊群，单独的DHL群。
