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.
本研究旨在确定与宠物犬粪便中存在沙门氏菌相关的宠物管理因素。2005 年 10 月至 2006 年 5 月，从安大略省 84 户家庭中招募了 138 只犬参与横断面研究。从每只犬连续采集 5 份粪便样本，进行沙门氏菌富集培养。结果显示，出乎预料的是，有 23.2%（32/138）的犬至少有一份粪便样本呈沙门氏菌阳性，25%（21/84）的家庭至少有一只犬排出沙门氏菌。鉴定出 12 种血清型的沙门氏菌肠亚种，其中主要血清型为肠炎沙门氏菌（33.3%；13/39）、肯塔基沙门氏菌（15.4%；6/39）、勃兰登堡沙门氏菌（15.4%；6/39）和海德堡沙门氏菌（12.8%；5/39）。建立了带有家庭随机效应的单变量逻辑回归模型，以解释聚类现象。犬检测呈阳性的统计学显著风险因素包括与家畜接触、在过去 30 天内服用益生菌、食用商业或自制生食、食用生肉和鸡蛋、食用自制熟食以及家庭中养有多只犬。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学意义。这些结果突出了在犬类饮食中添加生动物产品可能带来的公共卫生风险。
