phylogenetic analysis of the francisella-like endosymbionts of dermacentor ticks.bacterial endosymbionts with significant homology to francisella tularensis (gamma-proteobacteria) have been described from at least five species of ticks in three different genera, including two north american dermacentor species [d. andersoni stiles and d. variabilis (say)]. the evolutionary relationships among the francisella-like endosymbionts (fle) from different hosts and between fle and the arthropod-borne pathogen f. tularensis are not known. a 1,169-base fragment of the 16s rdna and a 7 ...200415185926
prevalence of rickettsia species in dermacentor variabilis ticks from ontario, canada.relatively little is known about the prevalence of rickettsial species in dermacentor ticks in eastern canada. in this study, dermacentor ticks from the province of ontario, canada, were tested for the presence of spotted fever group rickettsial (sfgr) species, coxiella burnetii and francisella tularensis. rickettsia rickettsii was not detected in any ticks tested, but r. montanensis was detected at a prevalence of 2.2% in d. variabilis (17/778). two other sfgr species, r. parkeri and candidatus ...201627318438
a francisella-like endosymbiont in the gulf coast tick evolved from a mammalian pathogen.ticks (order ixodida) vector pathogenic bacteria that cause diseases in humans and other mammals. they also contain bacteria that are closely related to pathogens but function as endosymbionts that provide nutrients that are missing from mammalian blood-their sole food source. for instance, mammalian pathogens such as coxiella burnetii and francisella tularensis, as well as coxiella-like and francisella-like endosymbionts (cles and fles, respectively) occur in ticks worldwide. however, it is not ...201627645766
