Salmonella carriage in 5888 gulls sampled by cloacal lavage was found to be 7.8%. Marked geographical and seasonal differences in carriage rates were found. These differences appeared to be associated with human population density and seasonal differences in the reported incidence of human salmonellosis. The maximum duration of salmonella excretion in 17 laboratory-maintained gulls was 4 days and the number of salmonellae excreted was never more than 170 per gram of faeces. On the basis of this study it is suggested that gulls are not important factors in the aetiology of human salmonellosis.
通过泄殖腔灌洗对5888只海鸥进行采样，发现沙门氏菌携带率为7.8%。研究发现携带率存在显著的地理和季节差异。这些差异似乎与人口密度以及报告的人类沙门氏菌病发病率的季节差异有关。17只实验室饲养的海鸥中，沙门氏菌排泄的最长持续时间为4天，每克粪便中排泄的沙门氏菌数量从未超过170个。基于这项研究，有人认为海鸥并非人类沙门氏菌病病因中的重要因素。
