Detection and Genetic Diversity of Heritable Bacterial Symbionts in Human Lice Based on 16S-rRNA Gene.

ABSTRACT: Human lice are obligate bloodsucking ectoparasites harbouring endosymbiotic bacteria essential for their survival. Despite the medical significance of human lice, their endosymbionts remain understudied, and knowledge about their species identity, prevalence and genetic diversity is largely limited. Head, body and pubic louse specimens' collection from infested patients of various origins between 2019 and 2023 enabled molecular screening for distribution and genetic diversity of bacterial endosymbionts through conventional PCR targeting two fragments of 16S-rRNA. A total of 209 louse specimens isolated from infested patients, including 186 head lice, 11 body lice and 12 pubic lice were examined with 77.5%, 41.7% and 94.3% of the specimens found to be infested with Candidatus Riesia pedicul
