A survey of 2 horse populations was done to detect the number of asymptomatic faecal excretors of Salmonella sp. 1201 faecal samples from 250 horses hospitalised at the University of Sydney were cultured. Three serotypes, S. typhimurium (4 horses), S. anatum (2) and S. tennessee (1) were isolated from 7 horses (2.8%). None was detected in 75 mares similarly examined at a thoroughbred stud farm. In retrospect, S. typhimurium was also the most common (70%) of the 19 serotypes recovered from 171 horses with clinical salmonellosis seen at Camden, 1969 to 1986. Forty cases occurring since 1983 were reviewed in detail; the mortality rate was high (60%) and an increased proportion was due to S. bovis-morbificans. Five horses developed salmonellosis while hospitalised and it was usually impossible to be certain whether these cases developed from the carrier state into overt disease or resulted from infections acquired in hospital.
对两群马进行了调查，以检测沙门氏菌属无症状粪便排泄者的数量。对悉尼大学收治的250匹马的1201份粪便样本进行了培养。从7匹马（2.8%）中分离出三种血清型，即鼠伤寒沙门氏菌（4匹）、鸭沙门氏菌（2匹）和田纳西沙门氏菌（1匹）。在一个纯种种马场对75匹母马进行类似检查时，未检测到任何沙门氏菌。回顾过去，鼠伤寒沙门氏菌也是1969年至1986年在卡姆登见到的171例临床沙门氏菌病马所分离出的19种血清型中最常见的（70%）。对1983年以来发生的40例病例进行了详细回顾；死亡率很高（60%），且由牛病沙门氏菌导致的病例比例有所增加。有5匹马在住院期间患上了沙门氏菌病，通常无法确定这些病例是从携带状态发展为显性疾病，还是因医院感染所致。
