Salmonella causes an estimated 1·2 million illnesses annually in the USA. Salmonella enterica serotype Javiana (serotype Javiana) is the fourth most common serotype isolated from humans, with the majority of illnesses occurring in southeastern states. The percentage of wetland cover by wetland type and the average incidence rates of serotype Javiana infection in selected counties of the Foodborne Disease Active Surveillance Network (FoodNet) were examined. This analysis explored the relationship between wetland environments and incidence in order to assess whether regional differences in environmental habitats may be associated with observed variations in incidence. Findings suggest that environmental habitats may support reservoirs or contribute to the persistence of serotype Javiana, and may frequently contribute to the transmission of infection compared with other Salmonella serotypes.
在美国，沙门氏菌每年估计导致120万例疾病。肠炎沙门氏菌雅维阿纳血清型（雅维阿纳血清型）是从人类分离出的第四常见血清型，大多数疾病发生在东南部各州。研究了食源性疾病主动监测网络（FoodNet）选定县的湿地类型覆盖的湿地百分比以及雅维阿纳血清型感染的平均发病率。该分析探讨了湿地环境与发病率之间的关系，以评估环境栖息地的区域差异是否可能与观察到的发病率变化相关。研究结果表明，环境栖息地可能支持储存宿主或有助于雅维阿纳血清型的持续存在，并且与其他沙门氏菌血清型相比，可能经常导致感染传播。
