Enterocytozoon bieneusi, a zoonotic pathogen prevalent in both humans and animals, is the most frequently diagnosed microsporidian species in humans and presents significant public health risks. However, data on the prevalence and genotypes of E. bieneusi in farmed minks (Neovison vison) and raccoon dogs (Nyctereutes procyonoides) in China are limited. Therefore, 275 minks (89 from Hebei Province, 57 from Heilongjiang Province, 109 from Liaoning Province, 20 from Shandong Province) and 235 raccoon dogs (114 from Hebei Province, 27 from Heilongjiang Province, 61 from Liaoning Province, 33 from Jilin Province) were examined for the prevalence and genotypes of E. bieneusi through sequence analysis of the internal transcribed spacer (ITS) region of the rRNA gene. The overall prevalence of E. bieneusi was 18.6% (95/510), with 10.5% (29/275) in farmed minks and 28.1% (66/235) in raccoon dogs. Ten genotypes (CHN-F1, genotype D, Type IV, EbpC, NCF2, NCF5, NCF6, Peru8, Henan V, and MJ5) were identified in minks and raccoon dogs. This study is the first to detect the CHN-F1, NCF2, NCF6, Peru8, and Henan V genotypes in minks and the NCF5, NCF6, and MJ5 genotypes in raccoon dogs. Additionally, the D, Type IV, and Peru8 genotypes, previously identified in humans, were also found in minks and raccoon dogs, suggesting that these animals could be potential sources of human microsporidiosis. These findings expand the understanding of E. bieneusi’s host distribution in China and contribute to the prevention of zoonotic E. bieneusi infections among farmed animals.
Résumé
Enterocytozoon bieneusi, pathogène zoonotique répandu chez les humains et les animaux, est l’espèce de microsporidie la plus fréquemment diagnostiquée chez les humains et présente des risques importants pour la santé publique. Cependant, les données sur la prévalence et les génotypes d’E. bieneusi chez les visons (Neovison vison) et les chiens viverrins (Nyctereutes procyonoides) en élevage en Chine sont limitées. Par conséquent, 275 visons (89 de la province du Hebei, 57 de la province du Heilongjiang, 109 de la province du Liaoning, 20 de la province du Shandong) et 235 chiens viverrins (114 de la province du Hebei, 27 de la province du Heilongjiang, 61 de la province du Liaoning, 33 de la province du Jilin) ont été examinés pour la prévalence et les génotypes d’E. bieneusi par analyse de séquence de la région de l’espaceur interne transcrit (ITS) du gène de l’ARNr. La prévalence globale d’E. bieneusi était de 18,6 % (95/510), avec 10,5 % (29/275) chez les visons d’élevage et 28,1 % (66/235) chez les chiens viverrins. Dix génotypes (CHN-F1, génotype D, Type IV, EbpC, NCF2, NCF5, NCF6, Peru8, Henan V et MJ5) ont été identifiés chez les visons et les chiens viverrins. Cette étude est la première à détecter les génotypes CHN-F1, NCF2, NCF6, Peru8 et Henan V chez les visons et les génotypes NCF5, NCF6 et MJ5 chez les chiens viverrins. De plus, les génotypes D, Type IV et Peru8, précédemment identifiés chez l’homme, ont également été trouvés chez les visons et les chiens viverrins, suggérant que ces animaux pourraient être des sources potentielles de microsporidiose humaine. Ces résultats élargissent la compréhension de la distribution des hôtes d’E. bieneusi en Chine et contribuent à la prévention des infections zoonotiques à E. bieneusi chez les animaux d’élevage.
