Salmonella Prevalence and Persistence in Companion Animals

项目总结 沙门氏菌感染是中国人因食源性疾病死亡的主要原因。 美国。尽管人类沙门氏菌病通常与摄入 受污染的食物，宠物可能是另一个感染源。狗和猫并不常见 沙门氏菌被认为是沙门氏菌的携带者，但沙门氏菌在这些宠物中的感染是众所周知的。 猫狗沙门氏菌感染的危险因素包括食用生肉饮食 以及受污染的食物，如猪耳朵。还有沙门氏菌的暴发。 饲喂干商业饲料的宠物感染。人们在接触沙门氏菌时会接触到沙门氏菌 受污染的宠物食品和零食。尽管认识到这些情况和潜在的风险 对于狗和猫的沙门氏菌病，沙门氏菌培养在这些物种中并不是常规的。 我们建议研究狗和猫的沙门氏菌脱落，因为1)沙门氏菌感染是 狗和猫是公认的；2)狗和猫与人密切相关， 特别是儿童；3)宠物食品和食品的污染是众所周知的，并已造成 人类沙门氏菌病病例；以及4)狗和猫没有进行沙门氏菌常规筛查 尽管认识到狗和猫感染沙门氏菌的风险，但仍在脱落。我们会 测量有症状和无症状狗的沙门氏菌脱落率，并 猫通过粪便培养。

PROJECT SUMMARY Salmonella infection is the leading cause of human death due to foodborne illness in the United States. Although human salmonellosis is usually associated with the consumption of contaminated food, pets can be another source of infection. Dogs and cats are not commonly thought of as carriers of Salmonella, but Salmonella infection is well-recognized in these pets. Risk factors for Salmonella infection in dogs and cats include consumption of raw meat diets and contaminated treats such as pig ears. There have also been outbreaks of Salmonella infection in pets fed dry commercial diets. People can be exposed to Salmonella when handling contaminated pet food and treats. Despite recognition of these cases and the potential risk of salmonellosis in dogs and cats, Salmonella culture is not routinely performed in these species. We propose to study Salmonella shedding in dogs and cats because 1) Salmonella infection is well-recognized in dogs and cats; 2) dogs and cats live in close association with people, particularly children; 3) contamination of pet foods and treats is well-recognized and has caused cases of human salmonellosis; and 4) dogs and cats are not routinely screened for Salmonella shedding despite recognition of the risk of Salmonella infection in dogs and cats. We will measure the prevalence of Salmonella shedding in symptomatic and asymptomatic dogs and cats through fecal culture.
