Nidoviruses are increasingly detected in various snake species worldwide, but much remains to be learned about their distribution and the factors influencing their epidemiology.
This retrospective study evaluated the results of routine nidovirus testing, by PCR, of 5210 swab samples from pet snakes from various European countries that were submitted to a commercial veterinary laboratory in Germany between 2016 and 2021.
The overall detection rate was 19.96%. However, the detection rate varied significantly depending on the snake species (p < 0.0001), with the highest rate in Indian pythons (Python molurus) (42.24%). Rates also varied depending on the season of sample collection (p < 0.0001), with the highest rate in winter (24.46%), and the country of sample origin (p < 0.0001), with the highest rate in Austria (36.69%). The detection rate also decreased significantly (p = 0.0003) over the 6-year observation period, from 26.43% to 17.64%.
No information on clinical signs was available for most of the sampled snakes.
The present study supplies new information on the distribution of python nidoviruses (subgenus Roypretovirus) in pet snakes in Europe and indicates a dynamic situation with possible changes in prevalence over time.
冠状病毒在世界范围内的各种蛇种中越来越多地被检测到,但对于它们的分布以及影响其流行病学的因素仍有很多需要了解。
本回顾性研究评估了 2016 年至 2021 年间,从来自不同欧洲国家的 5210 个宠物蛇拭子样本中,通过 PCR 对冠状病毒进行常规检测的结果。这些样本由德国一家商业兽医实验室收集。
总体检测率为 19.96%。然而,检测率因蛇种而异(p < 0.0001),印度蟒蛇(Python molurus)的检测率最高(42.24%)。检测率还因采样季节而异(p < 0.0001),冬季最高(24.46%),因采样国而异(p < 0.0001),奥地利最高(36.69%)。在 6 年的观察期内,检测率也显著下降(p = 0.0003),从 26.43%降至 17.64%。
大多数采样蛇的临床症状信息不可用。
本研究提供了有关欧洲宠物蛇中蟒蛇冠状病毒(属 Roypretovirus)分布的新信息,并表明其流行情况存在动态变化,可能随时间发生变化。
