Abstract

A cross-sectional survey was conducted on 75 randomly selected dairies in one California county. Salmonella was isolated from 12 (16%) dairies; S newport was isolated from 6 (8%). Chloramphenicol-resistant S newport and S dublin were isolated from 8 (10.7%) dairies. Dairies with Salmonella had higher average calf mortality rates (P = 0.064; odds ratio [OR], 3.8). Dairies with S newport had a greater than expected occurrence of illnesses in adult cows compared with dairies with no S newport (P = 0.048; OR, 6.7) or with no Salmonella serotypes isolated (P = 0.047; OR, 6.9). Dairies with chloramphenicol-resistant Salmonella were more likely to have used chloramphenicol during the preceding 18-month period compared with dairies with chloramphenicol-susceptible Salmonella or no Salmonella (P = 0.023; OR, 9.5).

摘要

在加利福尼亚州的一个县，对75家随机选取的奶牛场进行了横断面调查。从12家（16%）奶牛场分离出了沙门氏菌；从6家（8%）奶牛场分离出了纽波特沙门氏菌。从8家（10.7%）奶牛场分离出了耐氯霉素的纽波特沙门氏菌和都柏林沙门氏菌。有沙门氏菌的奶牛场犊牛平均死亡率更高（P = 0.064；优势比[OR]，3.8）。与没有纽波特沙门氏菌的奶牛场（P = 0.048；OR，6.7）或未分离出任何沙门氏菌血清型的奶牛场（P = 0.047；OR，6.9）相比，有纽波特沙门氏菌的奶牛场成年母牛患病情况高于预期。与有氯霉素敏感型沙门氏菌或无沙门氏菌的奶牛场相比，有耐氯霉素沙门氏菌的奶牛场在之前18个月内更有可能使用过氯霉素（P = 0.023；OR，9.5）。
