In recent years, emerging pathogens have received special attention due to their consequences for public health. Given that Arcobacter has been isolated in Costa Rica from commercial meat poultry samples, the aim of this research was to determine its isolation frequency from laying hens, broilers, ducks, and geese and to compare two types of samples, namely, cloacal swabs and stool collection. Arcobacter was isolated from 22 (11%) of the 200 samples examined. Fifteen (55%), eight (30%), and four (15%) of the isolated strains were identified as A. butzleri, A. cryareophilus, and Arcobacter spp., respectively. Also, there is a statistically significant difference among the isolation frequencies of Arcobacter for the types of samples evaluated, yielding more isolates from stool samples than from cloacal swab collection. This work describes the distribution of Arcobacter in farm animals as potential sources for its spread from animal-derived products.
近年来，新兴病原体因其对公共卫生的影响而受到特别关注。鉴于在哥斯达黎加已从商业肉禽样本中分离出嗜冷栖热菌，本研究的目的是确定其从蛋鸡、肉鸡、鸭和鹅中的分离频率，并比较两种样本类型，即泄殖腔拭子和粪便采集样本。在所检测的200个样本中，有22个（11%）分离出了嗜冷栖热菌。分离出的菌株中，分别有15个（55%）、8个（30%）和4个（15%）被鉴定为布氏嗜冷栖热菌、嗜冷栖热弧菌和嗜冷栖热菌属。此外，在所评估的样本类型中，嗜冷栖热菌的分离频率存在统计学上的显著差异，粪便样本中的分离株比泄殖腔拭子采集样本中的更多。这项工作描述了嗜冷栖热菌在农场动物中的分布情况，这些动物是其通过动物源性产品传播的潜在源头。
