A nation-wide survey was conducted to estimate the prevalence of Salmonella enteritidis and other salmonellas among Canadian commercial broiler flocks. Environmental (litter and/or water) samples from 226 of 294 (76.9%) randomly selected flocks were contaminated with salmonellas. Litter samples were more often contaminated with salmonellas than water samples (47.4 v. 12.3%). Fifty different salmonella serovars were isolated. The most prevalent serovars were S. hadar, S. infantis, and S. schwarzengrund; they were isolated from samples of 98/294 (33.3%), 26/294 (8.8%), and 21/294 (7.1%) flocks, respectively. Feed samples of 39/290 (13.4%) flocks were contaminated with salmonellas. Salmonella enteritidis was isolated from the environmental samples of 9/294 (3.1%) flocks. Salmonella enteritidis phage type (PT) 8 was isolated from seven flocks, and PT 13a from two flocks.
开展了一项全国性调查，以估计加拿大商业肉鸡群中肠炎沙门氏菌和其他沙门氏菌的流行情况。在随机选取的294个鸡群中，有226个（76.9%）鸡群的环境（垫料和/或水）样本被沙门氏菌污染。垫料样本比水样更常被沙门氏菌污染（47.4%对12.3%）。分离出了50种不同的沙门氏菌血清型。最常见的血清型是哈达尔沙门氏菌、婴儿沙门氏菌和施瓦岑贝格沙门氏菌；它们分别从98/294（33.3%）、26/294（8.8%）和21/294（7.1%）的鸡群样本中分离出来。39/290（13.4%）鸡群的饲料样本被沙门氏菌污染。从9/294（3.1%）鸡群的环境样本中分离出肠炎沙门氏菌。从7个鸡群中分离出肠炎沙门氏菌噬菌体分型（PT）8，从2个鸡群中分离出PT 13a。
