[Endocellular pathogenic bacteria in the monogenean Euzetrema knoepffleri]. / Mise en évidence de bactéries endocellulaires pathogènes chez le Monogène Euzetrema knoepffleri

ABSTRACT

Intracellular bacteria (Rickettsia) are found in the Monogenean Euzetrema knoepffleri, vesicular endoparasite of the Amphibian Euproctus montanus (Urodela). In some conditions, they cause cytoplasmic damage in the host tissues, which demonstrates their pathogenicity. These bacteria are present during all the stages of the life-cycle of E. knoepffleri. Their transmission from one generation to the next occurs through the gametes.
