Francisella is a genus of bacterial pathogens potentially lethal to humans. 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 e...

From January 1998 through September 1999, 324 dogs in three northwestern Georgia counties were examined for ticks. Six species of ticks were recovered. The three most commonly collected ticks were the American dog tick, Dermacentor variabilis (Say) (310 male male, 352 female female; prevalence, 97%; mean intensity 2.1); the brown dog tick, Rhipicephalus sanguineus (Latreille) (118 male male, 11...

Introduction Ticks are non-permanent obligate parasites that have considerable medical-veterinary and zoonosis importance. In this regard a study designed to investigate the distribution and fauna of ticks in the Alashtar county in Iran from April and March 2014. Methods Ticks were collected from livestock farms and facilities from selected rural and geographically location in the Alashtar co...

Ticks were collected at monthly intervals for 16 consecutive months from individual dogs by their owners in or close to the town of Stellenbosch, Western Cape Province. They were also collected for 27 consecutive months from dogs presented for a variety of reasons at three veterinary clinics in Stellenbosch, and from dogs upon admission to an animal welfare shelter. At one of the veterinary cli...

During 2006-2008, a total of 260 adult ticks were collected from domestic and wild animals in different regions of the state of Santa Catarina (SC), Brazil, including areas where human cases of Brazilian spotted fever have been reported. Collected ticks belonging to nine species (Amblyomma aureolatum, Amblyomma cajennense, Amblyomma dubitatum, Amblyomma longirostre, Amblyomma ovale, Amblyomma t...

Blood specimens from clinically normal military dogs and their trainers, in Lara, Venezuela were screened for Anaplasma platys, A. phagocytophilum, or Ehrlichia ewingii using 16S rRNA PCR tests. Sixteen percent (7/ 43) of dog specimens were positive by A. platys PCR test followed by sequencing of the PCR products, and all human blood specimens [25] were negative. All specimens from these dogs a...
