数据表明，人类食源性疾病中肠道沙门氏菌特定血清型的患病率与其在饲料中的患病率无关。鉴于饲料是S的次优环境。因此，在家禽饲料中的存活率可能是与沙门氏菌特定血清型的毒力无关的独立因素。此外，S.肠道菌血清型似乎具有不同的宿主特异性，并且在这些宿主中引起疾病的能力也依赖于血清型。血清型之间的这些差异可能与基因的存在或缺失以及这些基因的表达水平有关。随着对血清型特异性的更好理解，可以实施缓解方法来控制收获前和收获后水平的沙门氏菌。
Data indicate that prevalence of specific serovars of Salmonella enterica in human foodborne illness is not correlated with their prevalence in feed. Given that feed is a suboptimal environment for S. enterica, it appears that survival in poultry feed may be an independent factor unrelated to virulence of specific serovars of Salmonella. Additionally, S. enterica serovars appear to have different host specificity and the ability to cause disease in those hosts is also serovar dependent. These differences among the serovars may be related to gene presence or absence and expression levels of those genes. With a better understanding of serovar specificity, mitigation methods can be implemented to control Salmonella at preharvest and postharvest levels.
