This study investigated the effects of Kudoa septempunctata genotype ST3 spores on ddY suckling mice. Purified Kudoa septempunctata spores were administered into the stomachs of the mice at 5 × 106 or 5 × 107 spores/mouse, with inactivated Kudoa (5 × 106 spores/mouse) or vehicle as controls. No abnormal clinical symptoms were observed and there were no variations in fluid accumulation ratio and cytokine gene expression in all groups. In addition, intact Kudoa spores and the 18S rDNA gene were only detected (by microscopy and quantitative PCR, respectively) in the groups administered such spores. This study thus confirms that spores from the ST3 strain of Kudoa septempunctata were excreted in the faeces without infecting the gastrointestinal tract in ddY suckling mice.
Résumé
Cette étude a examiné les effets des spores de Kudoa septempunctata, de génotype ST3, sur des souriceaux à la mamelle de race ddY. Les spores purifiées de Kudoa septempunctata ont été administrées dans les estomacs des souris à 5 × 106 ou 5 × 107 spores/souris, avec comme témoins des Kudoa inactivés (5 × 106 spores/souris) ou un véhicule. Dans tous les groupes, aucun symptôme clinique anormal n’a été observé et il n’y avait pas de variation dans les taux d’accumulation de fluide ni dans l’expression des gènes de cytokines. De plus, des spores de Kudoa intactes et le gène d’ADNr 18S de Kudoa ont été détectés uniquement (par microscopie et PCR quantitative, respectivement) dans les groupes auxquels ont été administrées ces spores. Cette étude confirme donc que les spores de la souche ST3 de Kudoa septempunctata ont été excrétées dans les fèces sans infecter le tractus gastro-intestinal chez les souriceaux ddY à la mamelle.
