Description d’un sérogroupe (0103) d’Escherichia coli entéropathogène chez le lapin au sevrage

A partir de huit souches d'Escherichia coli (sérogroupe 0103) isolées de lapins atteints de diarrhée au sevrage, sept provoquent une dilatation de l'anse intestinale du lapin comparée à celle d'une souche positive humaine de contrôle n° 14 du CDC. Les auteurs inoculent l'estomac de 38 lapins, de 4 à 9 semaines, avec 10 x 1010 à 10u d'une souche du sérogroupe 0103. Diarrhée et mortalité (22 à 66 %) surviennent 4 jours après l'infection. L'autopsie révèle une typhlite grave, une multiplication excessive d'Escherichia coli de la flore, une élévatio� du pH au-dessus de 6,5, phénomènes observés dans la maladie naturelle. Au contraire, ils n'obtiennent aucun signe de maladie aux mêmes concentrations et par la même voie, avec une souche saprophyte de lapin et avec trois souches entéropathogènes du porc.
