Ticks harbour diverse microbial communities, but opportunistic and environmentally associated bacteria within these systems remain poorly understood. During attempts to establish primary cell cultures from surface-sterilized embryos of the dog tick Rhipicephalus linnaei , we detected the presence of Stenotrophomonas maltophilia , a multidrug-resistant environmental bacterium and emerging opportunistic pathogen. Microscopic exa...

Midichloria spp. are intracellular bacterial symbionts of ticks. Representatives of this genus colonise mitochondria in the cells of their hosts. To shed light on this unique interaction we evaluated the presence of an intramitochondrial localization for three Midichloria in the respective tick host species and generated eight high‐quality draft genomes and one closed genome, showing that this trait is non‐monophyletic, either...
