随着给水工业现代化及疫苗的推行使用,伤寒、副伤寒的大流行已基本得到控制。但非伤寒副伤寒沙门氏菌感染却仍然是一个遍及全球的腹泻原因。其抗原结构复杂,依菌体抗原分群,依鞭毛抗原分型,目前已发现1000个以上血清菌型。它们绝大部分可使动物致病或成为保存宿主。其中以鼠伤寒(S Typhimurium)分布最广,动物带菌者最多,耐药性最严重,如
With the modernization of the water supply industry and the introduction and use of vaccines, the typhoid and paratyphoid pandemics have basically been brought under control. However, non-Typhoid Salmonella typhi infection is still a cause of diarrhea throughout the world. Its antigen structure is complex, according to bacterial antigen grouping, according to flagella antigen typing, has been found in more than 1000 serum strains. Most of them can cause disease or become hosts for conservation. Among them, Typhimurium is the most widely distributed and has the highest number of carriers and the most drug-resistant species. For example,
