Salmonella belonging to 47 serotypes was isolated from animals at the University of California Veterinary Medical Teaching Hospital during the years 1974 to 1983. Salmonella belonging to 12 serotypes accounted for 89% of the 725 isolates. Salmonella typhimurium (including var copenhagen) was the most commonly isolated serotype, but during 1981 to 1983, S krefeld and S saint-paul were predominant. Certain serotypes seemed to be isolated more frequently from extraintestinal sources (S typhi-suis, S dublin). Although resistance to ampicillin, kanamycin, neomycin, streptomycin, and sulfonamides was common (greater than 60% of the isolates were resistant), resistance to chloramphenicol, gentamicin, and trimethoprim-sulfonamides was infrequent, except for isolates of S krefeld and S saint-paul.
1974年至1983年间，从加利福尼亚大学兽医学院教学医院的动物中分离出了属于47种血清型的沙门氏菌。属于12种血清型的沙门氏菌占725株分离菌的89%。鼠伤寒沙门氏菌（包括哥本哈根变种）是最常分离出的血清型，但在1981年至1983年期间，克雷费尔德沙门氏菌和圣保罗沙门氏菌占主导地位。某些血清型似乎更常从肠外来源分离出来（猪伤寒沙门氏菌、都柏林沙门氏菌）。虽然对氨苄青霉素、卡那霉素、新霉素、链霉素和磺胺类药物的耐药性很常见（超过60%的分离菌耐药），但除了克雷费尔德沙门氏菌和圣保罗沙门氏菌的分离菌外，对氯霉素、庆大霉素和甲氧苄啶-磺胺类药物的耐药性很少见。
