Abstract in another language

In the present study, Rickettsia sp. was detected in four water beetles of the genus Deronectes (Dytiscidae) for the first time. Rickettsiae were found in 100% of examined specimens of Deronectes platynotus (45/45), 39.4% of Deronectes aubei (28/71), 40% of Deronectes delarouzei (2/5) and 33.3% of Deronectes semirufus (1/3). Analysis of 16S rRNA gene sequences revealed a phylogenetic relationship with rickettsial isolates of Limonia chorea (Diptera), tentatively classified as members of the basal ancestral group. Phylogenetic analysis of the gltA (citrate synthase) gene sequences showed that Deronectes symbionts were closest to bacterial symbionts from spiders. Ultrastructural examinations revealed typical morphological features and intracellular arrangements of rickettsiae. The distribution, transmission and localization of Rickettsia sp. in D. platynotus were studied using a diagnostic PCR assay and FISH. Eggs from infected females of D. platynotus were all Rickettsia-positive, indicative of a vertical transmission.
