从1996年到2004年，在美国国家主动食源性疾病监测项目FoodNet中，Javiana沙门氏菌感染的发病率增加。与两栖动物的接触和西红柿的消费与贾维纳葡萄球菌感染的暴发有关。为了生成和测试与散发性S.javiana感染相关的风险因素的假设，我们采访了2004年8月至10月在佐治亚州和田纳西州确认的实验室确认的S.javiana感染的患者。我们从病例中收集了有关食物和水的消耗、动物接触和环境暴露的数据。将答复与基于人群的调查暴露数据进行比较。对117名确诊的S.Javiana病例患者中的72名进行了采访。饮用井水[调整优势比(AOR)4.3，95%可信区间(CI)1.6~11.2]和接触爬行动物或两栖动物(AOR 2.6，95%，CI 0.9~7.1)与感染有关。食用西红柿(AOR 0.5，95%CI 0.3-0.9)和家禽(AOR 0.5，95%CI 0.2-1.0)是有保护作用的。我们的研究表明，环境因素与佐治亚州和田纳西州的S.Javiana感染有关。
From 1996 to 2004, the incidence of Salmonella Javiana infections increased in FoodNet, the U.S. national active foodborne disease surveillance programme. Contact with amphibians and consumption of tomatoes have been associated with outbreaks of S. Javiana infection. To generate and test hypotheses about risk factors associated with sporadic S. Javiana infections, we interviewed patients with laboratory-confirmed S. Javiana infection identified in Georgia and Tennessee during August-October 2004. We collected data on food and water consumption, animal contact, and environmental exposure from cases. Responses were compared with population-based Survey exposure data. Seventy-two of 117 identified S. Javiana case-patients were interviewed. Consumption of well water [adjusted odds ratio (aOR) 4.3, 95% confidence interval (Cl) 1.6-11.2] and reptile or amphibian contact (aOR 2.6, 95%, CI 0.9-7.1) were associated with infection. Consumption of tomatoes (aOR 0.5, 95% CI 0.3-0.9) and poultry (aOR 0.5, 95 % CI 0.2-1.0) were protective. Our study suggests that environmental factors are associated with S. Javiana infections in Georgia and Tennessee.
