摘要

We tested for plague (Yersinia pestis) in a puma population in the Greater Yellowstone Ecosystem (GYE) over 9 years, overlapping a case when a boy in the area became infected with plague. Antibodies to Y. pestis were detected in 8 of 17 (47%) pumas tested by complement-enzyme-linked immunosorbent assay, and the organism itself was detected in 4 of 11 (36%) pumas tested after necropsy. Neither puma sex nor age was significantly associated with Y. pestis exposure or mortality, although our sample size was small. The overall prevalence of exposure we recorded was similar to that found along the western slope of Colorado, which is adjacent to the Four Corners region, a known plague hotspot in the USA. This suggests that: (1) Y. pestis may be present at higher levels in the GYE than previously assumed; (2) plague is a significant source of mortality for local pumas (6.6% of sub-adult and adult mortality); and (3) pumas may be a useful sentinel for potential risk of plague exposure to humans throughout the West. We would also emphasize that hunters and others handling pumas in this region should be made aware of the possibility of exposure.

Pestis暴露或死亡率显着相关。我们记录的曝光的总体流行性与沿着科罗拉多州的西部坡度发现的普遍存在，它与四个角落区相邻，这是美国的已知瘟疫热点。这表明：（1）y.PETIS可能存在于GYE的较高水平，而不是以前假设; （2）瘟疫是当地彪马的主要死亡来源（次成人和成人死亡率的6.6％）; （3）PUMA可能是一个有用的哨兵，用于潜在的瘟疫暴露于整个西方人类的风险。我们还会强调猎人和其他处理该地区的披露的处理露口，意识到暴露的可能性。
