| francisella-like endosymbiont dna and francisella tularensis virulence-related genes in brazilian ticks (acari: ixodidae). | ticks are vectors of a variety of pathogens, including francisella tularensis. bacteria in the genus francisella have been identified mostly in the northern hemisphere and include tick endosymbionts. francisella has never been described in brazil, where amblyomma spp. ticks are known as the vector of many bacterial zoonotic pathogens. in the present work, we have identified bacterial dna sequences with identity to francisella genes in amblyomma dubitatum neumann dermacentor nitens (neumann), and ... | 2009 | 19351090 |
| applicability of in vitro bioassays for the diagnosis of ivermectin resistance in rhipicephalus microplus (acari: ixodidae). | the applicability of laboratory bioassays to diagnose ivermectin (ivm) resistance in rhipicephalus microplus was evaluated. adult immersion tests (aits), larval immersion tests (lits) and larval packet tests (lpts) were performed to characterise the effects of ivermectin toxicity on adults and larvae of a susceptible reference strain. the ait was determined to be a reasonable assay but requires a large number of individuals to attain interpretable results. the lit and lpt were validated with an ... | 2011 | 21978742 |
