Francisella-like endosymbiont in a tick collected from a chicken in southern thailand.

We report here for the first time a novel Francisella-like endosymbiont discovered in a hard-tick (Rhipicephalus sanguineus s.l.) obtained from a chicken (Gallus domesticus) in Thailand. The phylogenetic results indicate the 16S rDNA sequences of this Francisella bacterium form a unique clade with the Francisella-like endosymbiont of the tick species, Amblyomma varanense and Amblyomma helvolum, that have previously been found on snakes in Thailand. This species of Francisella is in a different group from the other Francisella-like endosymbionts previously reported from other countries. No Francisella was detected in Haemaphysalis wellingtoni ticks obtained from chickens in this study. PMID: 27244963 [PubMed - in process]
