Abstract

From August 1983 to February 1984, sampling was conducted on 200 slaughtered sows for Salmonella . The sampling was to determine the presence of Salmonella in cull sows at a Minnesota slaughtering establishment. The weight range of the sows varied from 300 to 400 lb. Two samples (mesenteric lymph nodes and cecal contents) were collected from each sow. Conventional methods, using enrichment and plating onto selective media followed by biochemical and serological analyses, were used to isolate and identify Salmonella serotypes. Salmonellae were isolated from the mesenteric lymph nodes and cecal contents of 167/200 (84%) sows. Nine Salmonella serotypes were identified. The four most frequently identified Salmonella serotypes ( S. agona , S. anatum , S. derby , S. java ) accounted for 71% (141/200) of the Salmonella -positive sows. Salmonella were isolated from 131/200 (66%) of the mesenteric lymph nodes examined and 60/200 (30%) of the cecal contents examined.

摘要

1983年8月至1984年2月，对200头屠宰母猪进行了沙门氏菌采样。此次采样旨在确定明尼苏达州一家屠宰场淘汰母猪中沙门氏菌的存在情况。母猪体重范围在300至400磅之间。从每头母猪采集了两个样本（肠系膜淋巴结和盲肠内容物）。采用传统方法，先进行增菌培养，然后接种到选择性培养基上，接着进行生化和血清学分析，以分离和鉴定沙门氏菌血清型。从167/200（84%）头母猪的肠系膜淋巴结和盲肠内容物中分离出了沙门氏菌。鉴定出了9种沙门氏菌血清型。四种最常见的沙门氏菌血清型（阿哥纳沙门氏菌、鸭沙门氏菌、德尔卑沙门氏菌、爪哇沙门氏菌）占沙门氏菌阳性母猪的71%（141/200）。在所检查的131/200（66%）个肠系膜淋巴结和60/200（30%）份盲肠内容物中分离出了沙门氏菌。
