摘要
Cryptosporidium is a significant zoonotic parasite with broad distribution in both humans and rodents. In this study, 510 fecal samples were collected from nine species of wild rodents across Guangxi, Yunnan, and Hunan Provinces in China. Nested PCR analysis targeting the SSU rRNA gene revealed an overall Cryptosporidium infection rate of 1.8% (9/510) among rodents in these provinces. The highest positivity rate was observed in Guangxi Province at 4.9% (5/103), followed by Yunnan Province (2.3%, 2/88), and Hunan Province (0.6%, 2/319). Notably, Rattus losea exhibited the highest prevalence rate at 9.8% (4/41), while Rattus flavipectus and Niviventer lotipes showed rates of 5.1% (2/39) and 4.4% (1/23), respectively. Various genotypes/species were identified, including Cryptosporidium viatorum, Cryptosporidium muris, Cryptosporidium vole genotype VII, and Cryptosporidium ratti, rat genotypes II, and IV. The study also found that wild rodents inhabiting mountainous areas had a higher prevalence rate at 4.9% (5/103) compared to those residing in fields and lake beaches, where prevalence rates were 2.1% (2/95) and 0.6% (2/312), respectively. This study provides new insights into Cryptosporidium infection rates among wild rodents and identifies two zoonotic species, C. viatorum and C. muris. These findings underscore the potential risk posed by Chinese wild rodent populations in transmitting zoonotic Cryptosporidium, which could significantly impact public health. Therefore, effective control strategies are needed to prevent transmission between humans and rodents. Cryptosporidium est un parasite zoonotique important avec une large distribution chez l'homme et les rongeurs. Dans cette & eacute;tude, 510 & eacute;chantillons f & eacute;caux ont & eacute;t & eacute; collect & eacute;s de neuf esp & egrave;ces de rongeurs sauvages dans les provinces du Guangxi, du Yunnan et du Hunan en Chine. L'analyse par PCR imbriqu & eacute;e ciblant le g & egrave;ne ARNr SSU a r & eacute;v & eacute;l & eacute; un taux global d'infection par Cryptosporidium de 1,8 % (9/510) parmi les rongeurs de ces provinces. Le taux de positivit & eacute; le plus & eacute;lev & eacute; a & eacute;t & eacute; observ & eacute; dans la province du Guangxi avec 4,9 % (5/103), suivie de la province du Yunnan (2,3 %, 2/88) et de la province du Hunan (0,6 %, 2/319). Notamment, Rattus losea a pr & eacute;sent & eacute; le taux de pr & eacute;valence le plus & eacute;lev & eacute; & agrave; 9,8 % (4/41), tandis que Rattus flavipectus et Niviventer lotipes ont affich & eacute; des taux de 5,1 % (2/39) et 4,4 % (1/23), respectivement. Divers g & eacute;notypes/esp & egrave;ces ont & eacute;t & eacute; identifi & eacute;s, notamment Cryptosporidium viatorum, Cryptosporidium muris, Cryptosporidium de campagnol g & eacute;notype VII et Cryptosporidium ratti, g & eacute;notypes de rats II et IV. L'& eacute;tude a & eacute;galement r & eacute;v & eacute;l & eacute; que les rongeurs sauvages habitant les zones montagneuses avaient un taux de pr & eacute;valence plus & eacute;lev & eacute;, de 4,9 % (5/103), par rapport & agrave; ceux r & eacute;sidant dans les champs et les bords de lacs, o & ugrave; les taux de pr & eacute;valence & eacute;taient respectivement de 2,1 % (2/95) et de 0,6 % (2/312). Cette & eacute;tude apporte de nouvelles perspectives sur les taux d'infection & agrave; Cryptosporidium chez les rongeurs sauvages et identifie deux esp & egrave;ces zoonotiques, C. viatorum et C. muris. Ces r & eacute;sultats soulignent le risque potentiel pos & eacute; par les populations de rongeurs sauvages chinois dans la transmission des Cryptosporidium zoonotiques, ce qui pourrait avoir des cons & eacute;quences importantes sur la sant & eacute; publique. Par cons & eacute;quent, des strat & eacute;gies de contr & ocirc;le efficaces sont n & eacute;cessaires pour pr & eacute;venir la transmission entre les humains et les rongeurs.
