In this study, the recombinant gut protein rRa92A produced in Pichia pastoris yeast cells was used to immunize cattle in two experiments, one in Brazil and the other in Uganda. In both experiments, the animals were intramuscularly (IM) injected with 200 µg of recombinant protein in Brazil on days 0, 30 and 51 and in Uganda on days 0, 30. Blood samples for sera separation were collected from different days in bo...

The majority of these substances are expressed by the parasite salivary gland and secreted in tick saliva. It is known that ...
The fatal cases of spotted fever reported in some Brazilian municipalities are generally associated with the presence of ticks and capybaras (Hydrochoerus hydrochaeris). The urban forest fragments where this rodent is present are of great concern. We investigated the diversity of free ticks as well as the occurrence of ticks infected by Rickettsia in one of these fragments, in Campo Grande city, Mato Grosso do ...

However, in some areas of Brazil where sand flies do not occur, this disease is found in humans and dogs. There has been speculation that ticks might play a role in transmission of canine visceral leishmaniasis and the DNA o...
Cattle ticks are responsible for great economic losses in cattle farming worldwide, and their main control method, chemicals, has been showing problems, whether resulting from the development of resistant strains of ticks or environmental contamination. Research studies directed toward developing vaccines against ticks are emerging. One way to evaluate those vaccines is to calculate the percentage of efficacy. ...
