Seroprevalence and risk factors associated with seropositivity for equine encephalomyelitis virus in horses in Rio Grande do Norte, Brazil

The present objective was to investigate the presence of anti-equine viral encephalomyelitis (EVE) antibodies and the possible risk factors for its dissemination in horses raised in the East and West Potiguar mesoregions of the state of Rio Grande do Norte, Brazil. Serological diagnosis for neutralizing ...

Rev. bras. ciênc. vet; 28 (4), 2021
A doença gastrintestinal relacionada à areia, também conhecida como enteropatia arenosa, é uma enfermidade gastrintestinal comum nos equinos mantidos a campo em regiões com solo arenoso frouxo resultando em sinais clínicos variáveis incluindo dor abdominal aguda, perda de peso, diarréia intermite...

Serological and molecular detection of Theileria equi in horses from Sinop, Mato Grosso state, Brazil

Rev. bras. ciênc. vet; 28 (3), 2021
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...

Evidence for current circulation of an ancient West Nile virus strain (NY99) in Brazil

Abstract INTRODUCTION: In Brazil, West Nile virus (WNV) was first detected, in 2018, in horses with neurological disease. AIM: We report the first case of WNV infection in a horse from Ceará state and the complete genome sequence of an isolate from Espírito Santo state. Both infections occurred in ...

Sarcocystis neurona, seroprevalence of antibodies in equines and research of oocystis in opossum in Ilhéus - Itabuna microregion, Bahia, Brazil

Abstract The aims of this study were to determine the seroprevalence of Sarcocystis neurona antibodies in equines in the Ilhéus-Itabuna microregion (BA), and identify possible factors associated with infection. The presence of sporocysts/oocysts of Sarcocystis spp. was also verified in Didelphis spp. A ...

Serological evidence of Rickettsia in horses from a semi-arid Brazilian region

Abstract Brazilian spotted fever (BSF) is a common tick-borne disease caused by Rickettsia rickettsii. Horses are the primary hosts of the main vector, Amblyomma sculptum, and are considered efficient sentinels for circulation of Rickettsia. Therefore, the aim of this study was to detect antibodies react...

Sarcocystis neurona and related Sarcocystis spp. shed by opossums (Didelphis spp.) in South America

Abstract Protozoan parasites of the genus Sarcocystis are obligatory heteroxenous cyst-forming coccidia that infect a wide variety of animals and encompass approximately 200 described species. At least four Sarcocystis spp. (S. falcatula, S. neurona, S. lindsayi and S. speeri) use opossums (Didelphis spp...
