| 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 |
| detection of theileria and babesia in brown brocket deer (mazama gouazoubira) and marsh deer (blastocerus dichotomus) in the state of minas gerais, brazil. | intraerythrocytic protozoan species of the genera theileria and babesia are known to infect both wild and domestic animals, and both are transmitted by hard-ticks of the family ixodidae. the prevalences of hemoprotozoa and ectoparasites in 15 free-living mazama gouazoubira, two captive m. gouazoubira and four captive blastocerus dichotomus from the state of minas gerais, brazil, have been determined through the examination of blood smears and the use of nested polymerase chain reaction (npcr). t ... | 2010 | 21354704 |
