P>本研究的目的是确定可能与沙门氏菌属存在相关的宠物相关管理因素。志愿者家庭的宠物狗的粪便中。从2005年10月到2006年5月，来自安大略省84个家庭的138只狗被招募来参加一项横断面研究。每天从每只狗身上连续采集五个粪便样本，并进行沙门氏菌富集培养。被执行。至少有一份粪便样本呈沙门氏菌阳性的狗数量（23.2%；32/138）高于预期，25%（21/84）的家庭至少有一只狗排出沙门氏菌。肠沙门氏菌亚种的十二种血清型。已鉴定出肠杆菌，主要血清型为鼠伤寒菌（33.3%；13/39）、肯塔基菌（15.4%；6/39）、勃兰登堡菌（15.4%；6/39）和海德堡菌（12.8%；5/39）。创建单变量逻辑回归模型，对家庭施加随机效应，以解释聚类。狗检测呈阳性的统计显着风险因素包括与牲畜接触、在过去 30 天内接受益生菌、喂养商业或自制生食、喂养生肉和鸡蛋、喂养自制熟食以及家里养多于一只狗。在控制生食喂养的双变量模型中，非饮食变量不再具有统计显着性。这些结果凸显了在犬类饮食中加入生动物产品的潜在公共健康风险。
P>The purpose of this study was to determine pet-related management factors that may be associated with the presence of Salmonella spp. in feces of pet dogs from volunteer households. From October 2005 until May 2006, 138 dogs from 84 households in Ontario were recruited to participate in a cross-sectional study. Five consecutive daily fecal samples were collected from each dog and enrichment culture for Salmonella spp. was performed. A higher than expected number of the dogs (23.2%; 32/138) had at least one fecal sample positive for Salmonella, and 25% (21/84) of the households had at least one dog shedding Salmonella. Twelve serotypes of Salmonella enterica subsp. enterica were identified, with the predominant serotypes being Typhimurium (33.3%; 13/39), Kentucky (15.4%; 6/39), Brandenburg (15.4%; 6/39) and Heidelberg (12.8%; 5/39). Univariable logistic regression models were created with a random effect for household to account for clustering. Statistically significant risk factors for a dog testing positive included having contact with livestock, receiving a probiotic in the previous 30 days, feeding a commercial or homemade raw food diet, feeding raw meat and eggs, feeding a homemade cooked diet, and having more than one dog in the household. In two-variable models that controlled for feeding raw food, the non-dietary variables were no longer statistically significant. These results highlight the potential public health risk of including raw animal products in canine diets.
