Neorickettsial endosymbionts of the digenea: diversity, transmission and distribution.

TL;DR: In this paper, the authors summarized the current knowledge on the transmission ecology of neorickettsiae, both for pathogenic species and for unknown pathogenicity, as well as their possible evolutionary associations with various groups of digeneans.
Journal ArticleDOI

The Beringian coevolution project: Holistic collections of mammals and associated parasites reveal novel perspectives on evolutionary and environmental change in the North

TL;DR: The Beringian Coevolution Project (BCP) has been a field program underway in the high northern latitudes since 1999, which has focused on building key scientific infrastructure for integrated specimen-based stud...

Large Scale Screening of Digeneans for Neorickettsia Endosymbionts Using Real-Time PCR Reveals New Neorickettsia Genotypes, Host Associations and Geographic Records

TL;DR: The results of screening 771 digenean samples for Neorickettsia collected from various vertebrates in terrestrial, freshwater, brackish, and marine habitats in the United States, China and Australia suggest that further surveys from broader geographic regions and wider selection ofDigenean taxa are likely to reveal new Neoricksettsia lineages as well as new digenesan host associations.

Transmission rates of the bacterial endosymbiont, Neorickettsia risticii, during the asexual reproduction phase of its digenean host, Plagiorchis elegans, within naturally infected lymnaeid snails.

TL;DR: This study quantified the transmission of Neorickettsia during the asexual reproductive phase of a digenean parasite, Plagiorchis elegans, developing within naturally parasitized lymnaeid pond snails, and indicates that, unlike the Wolbachia-filaria relationship, the NeorICKettsia-digenean relationship is not obligatory mutualism.
