Assessing the carriage of in animal reservoirs is essential to better understand epidemiology. Here, we evaluated the prevalence of thermophilic . in dogs and cats, hereafter defined as pets, and characterized ( isolates to assess their genetic diversity and their potential link with isolates from other animals or human cases. During a 6-month period, 304 feces samples were collected from pets. A significantly higher prevalence of thermophilic . was found in dogs compared with cats, as well as in dogs ≤ 1-year-old compared with older dogs. was the predominant species found in pets, and its genomic characterization revealed a high genetic diversity. Genotypes comparison with previously characterized isolates revealed a partial overlap between isolates from pets, chicken, cattle, and clinical cases. This overlap suggests the potential role of livestock and humans in pets' exposure to , or vice versa. The isolation of pets' specific profiles may suggest the existence of other sources of pet contamination or imply that pets may constitute a reservoir for . Because of the proximity between humans and pets, along with their frequent carriage of , human exposure to from pets can be more important than previously thought.
评估动物宿主中[具体微生物名称缺失]的携带情况对于更好地了解[具体微生物名称缺失]的流行病学至关重要。在此，我们评估了嗜热[具体微生物名称缺失]在犬和猫（以下定义为宠物）中的流行情况，并对[具体微生物名称缺失]分离株进行了特征分析，以评估它们的遗传多样性以及它们与其他动物或人类病例分离株的潜在联系。在6个月的时间里，从宠物中收集了304份粪便样本。与猫相比，犬中嗜热[具体微生物名称缺失]的流行率显著更高，并且与年龄较大的犬相比，1岁及以下的犬中流行率也显著更高。[具体微生物名称缺失]是在宠物中发现的主要物种，其基因组特征显示出高度的遗传多样性。与先前特征分析的分离株进行基因型比较发现，来自宠物、鸡、牛和临床病例的[具体微生物名称缺失]分离株之间存在部分重叠。这种重叠表明家畜和人类在宠物接触[具体微生物名称缺失]方面可能发挥的作用，反之亦然。宠物特定谱型的分离可能表明存在其他宠物污染来源，或者意味着宠物可能构成[具体微生物名称缺失]的宿主。由于人类与宠物的密切接触，以及宠物频繁携带[具体微生物名称缺失]，人类从宠物接触[具体微生物名称缺失]的情况可能比以前认为的更为重要。
