Bacteria associated with Amblyomma cajennense tick eggs
Ticks represent a large group of pathogen vectors that blood feed on a diversity of hosts. In the Americas, the Ixodidae ticks Amblyomma cajennense are responsible for severe impact on livestock and public health. In the present work, we present the isolation and molecular identification of a group of culturable bacteria associated with A. cajennense eggs from females sampled in distinct geogra...
متن کاملAmblyomma cajennense infestation on horses in two microregions of the state of Rio de Janeiro, Brazil Infestação por Amblyomma cajennense em equinos de duas microrregiões do estado do Rio de Janeiro, Brasil
The objective of this study was to evaluate factors associated with infestation by Amblyomma cajennense on horses in two microregions of the state of Rio de Janeiro. Horses on 62 farms in the municipalities of the Itaguaí and Serrana microregions were evaluated between January and May 2009.

متن کاملComparison of Two Methods to Quantify 2,6-Dichlorophenol from Tick Amblyomma cajennense by GC/MS-SIM
Amblyomma cajennense (Acari: Ixodidae) é um carrapato de grande importância sócioeconômica no subcontinente Sul-Americano. Apesar disso, pouco se conhece acerca de sua ecologia química, cuja informação é crucial para o seu controle. Nesse estudo, 2,6-diclorofenol (2,6-DCP), o feromônio sexual de A. cajennense foi quantificado por cromatografia gasosa acoplada a espectrometria de massas no modo ...
متن کاملInduction of complete courtship ritual in Amblyomma cajennense using 2,6-dichlorophenol at female-equivalent quantities Indução dos comportamentos de cortejo em Amblyomma cajennense pelo 2,6-diclorofenol em quantidades equivalentes às das fêmeas
In order to clarify the role of 2,6-dichlorophenol (2,6-DCP) in the courtship of Amblyomma cajennense, sexually mature males that had previously fed on rabbits were tested in bioassays. The males were released onto dummies treated with whole female extract or synthetic 2,6-DCP at a concentration of two female equivalents, or with hexane (control), and their responses were observed. In the prese...
متن کاملEquine Piroplasmosis Associated with Amblyomma cajennense Ticks, Texas, USA
We report an outbreak of equine piroplasmosis in southern Texas, USA, in 2009. Infection prevalence reached 100% in some areas (292 infected horses). Amblyomma cajennense was the predominant tick and experimentally transmitted Theileria equi to an uninfected horse. We suggest that transmission by this tick species played a role in this outbreak.
