Salmonellosis is an important zoonotic disease but little is known about the role that free-living animals play as carriers of this pathogen. Moreover, the primary route of infection in the wild needs to be elucidated. The aim of this study was to determine the source and the route of transmission of Salmonella enterica serovar Albany (S. Albany) infection in captive zoo wild animals in the Culiacán Zoo. A total of 267 samples were analyzed including 220 fecal samples from zoo animals, 15 fecal samples from rodents, 5 pooled samples each of two insects (Musca domestica and Periplaneta americana), and 22 samples of animal feed. We detected S. Albany in 28 (10.5%) of the samples analyzed, including in samples from raw chicken meat. Characterization of isolates was performed by serotyping and pulsed-field gel electrophoresis. All isolates shared a single pulsed-field gel electrophoresis profile, indicating a possible common origin. These data suggest that the infected meat consumed by the wild felines was the primary source of infection in this zoo. It is likely that the pathogen was shed in the feces and disseminated by insects and rats to other locations in the zoo.
沙门氏菌病是一种重要的人畜共患病，但关于自由生活的动物作为这种病原体携带者所起的作用，人们知之甚少。此外，还需要阐明野生动物的主要感染途径。本研究的目的是确定库利亚坎动物园圈养野生动物中肠炎沙门氏菌奥尔巴尼血清型（S. Albany）感染的来源和传播途径。共分析了267份样本，包括220份动物园动物的粪便样本、15份啮齿动物的粪便样本、两种昆虫（家蝇和美洲大蠊）各5份混合样本以及22份动物饲料样本。在分析的28份（10.5%）样本中检测到了S. Albany，包括来自生鸡肉的样本。通过血清分型和脉冲场凝胶电泳对分离株进行了鉴定。所有分离株共享单一的脉冲场凝胶电泳图谱，表明可能有共同来源。这些数据表明，野生猫科动物食用的受感染肉类是该动物园感染的主要来源。很可能病原体通过粪便排出，并由昆虫和老鼠传播到动物园的其他地方。
