Blood samples were collected from 153 animals and analyzed using molecular and s...
Equine piroplasmosis is the most important tick-borne disease to affect horses in Brazil. Theileria equi is one of the causative agents of equine piroplasmosis. Chronic cases are expected, in which the animals show no apparent signs of infection and remain asymptomatic but constitute a source of the infe...
Ehrlichiosis is a tick-borne disease highly prevalent in Brazil, and is relevant in canine clinical practice due to
its high morbidity and mortality. Its clinical signs are nonspecific and its phases are acute, lasting 2 to 4 weeks; subclinical,
i.e., asymptomatic; and chronic, resembling an autoimmune d...
The causes of death of cattle kept in pre-export feedlots (PEFs) and in feedlot for finishing for slaughter are described. Two studies were conducted: a retrospective study of mortality cases in feedlots from 2000 to 2017 registered at the “Laboratório Regional de Diagnóstico” of the “Faculdade d...
Abstract Tick-borne rickettsial pathogens (TBRP) are important causes of infections in both dogs and humans. Dogs play an important role as a biological host for several tick species and can serve as sentinels for rickettsial infections. Our aim was to determine the presence of TBRP in dogs and in dog-as...
