20世纪80年代初，人类感染沙门氏菌亚种的病例有所增加。在过去的5年里，英国的肠炎发病率有所下降，尤其是血清型肠炎感染病例的下降。这种下降是与蛋鸡接种血清型肠炎疫苗同时发生的。其他因素，如蛋鸡群生物安全性的提高、其他动物免疫力的增强以及牲畜感染适应宿主的沙门氏菌血清型数量的增加，很可能也在这种下降中发挥了作用。虽然人类沙门氏菌病例目前处于1987年以来的最低水平，但重要的是要记住，肠炎菌在人类感染中占主导地位的原因尚不清楚，其他血清型可能具有类似的特性，根除肠炎菌可能会为它们留下一席之地。
After rising in the early 1980s, the number of recorded human cases of Salmonella enterica subsp. enterica in the UK has fallen in the last 5 years, with a particular decline in cases of infection with serovar Enteritidis. This decline has been concomitant with the introduction of vaccination of egg-laying hens against serovar Enteritidis. It is likely that other factors such as improved biosecurity in egg-laying flocks, a build-up of immunity in other animals and the rise in the number of livestock infections with host-adapted serovars of Salmonella have also played a part in this decline. Although human Salmonella cases are currently at their lowest level since 1987, it is important to remember that the reasons for the dominance of Enteritidis in human infection are poorly understood and it is possible that other serovars could share similar properties and the eradicaion of Enteritidis may leave a niche for them to fill.
