ABSTRACT
Enterocytozoon bieneusi is the most common microsporidian species in humans and can affect over 200 animal species. Considering possible increasing risk of human E. bieneusi infection due to close contact with pet dogs and identification of zoonotic E. bieneusi genotypes, 589 fresh fecal specimens of pet dogs were collected from Yunnan Province, China to determine the occurrence of E. bieneusi, characterize dog-derived E. bieneusi isolates, and assess their zoonotic potential at the genotype level. Enterocytozoon bieneusi was identified and genotyped by PCR and sequencing of the internal transcribed spacer (ITS) region of the ribosomal RNA (rRNA) gene. Twenty-nine specimens (4.9%) were positive. A statistical difference was observed in occurrence rates of E. bieneusi in pet dogs among 11 sampling sites by Fisher's exact test. Fifteen genotypes were identified and all of them phylogenetically belonged to zoonotic group 1, including four known genotypes (EbpC, D, Peru 8, and Henan-III) and 11 novel genotypes. Genotype Henan-III was reported in dogs for the first time. The finding of known genotypes found previously in humans and novel genotypes falling into zoonotic group 1 indicates that dogs may play a role in the transmission of E. bieneusi to humans in the investigated areas.
Title Occurrence et caractérisation génétique d'Enterocytozoon bieneusi chez les chiens de compagnie dans la province du Yunnan, Chine. Abstract Enterocytozoon bieneusi est l'espèce de microsporidies la plus répandue chez l'homme et peut affecter plus de 200 espèces animales. Compte tenu du risque accru possible d'infection humaine à E. bieneusi en raison d'un contact étroit avec des chiens de compagnie et de l'identification de génotypes zoonotiques d'E. bieneusi, 589 échantillons fécaux frais de chiens de compagnie ont été collectés dans la province du Yunnan, en Chine, pour déterminer la présence d'E. bieneusi, caractériser les isolats obtenus de chiens, et évaluer leur potentiel zoonotique au niveau du génotype. Enterocytozoon bieneusi a été identifié et génotypé par PCR et séquençage de la région d'espacement transcrit interne (ITS) du gène de l'ARN ribosomal (ARNr). Vingt-neuf échantillons (4,9%) étaient positifs. Une différence statistique a été observée dans les taux de présence d'E. bieneusi chez les chiens de compagnie parmi 11 sites d'échantillonnage par le test exact de Fisher. Quinze génotypes ont été identifiés et tous appartenaient phylogénétiquement au groupe zoonotique 1, dont quatre génotypes connus (EbpC, D, Peru 8 et Henan-III) et 11 nouveaux génotypes. Le génotype Henan-III est signalé pour la première fois chez le chien. La découverte de génotypes connus précédemment trouvés chez l'homme et de nouveaux génotypes appartenant au groupe zoonotique 1 indique que les chiens peuvent jouer un rôle dans la transmission d'E. bieneusi aux humains dans les zones étudiées.
