This study aimed to verify the prevalence of anti-Neospora caninum antibodies in dairy cows from municipalities of Resende and Rio Claro, both located at sulfluminense dairy belt. A total of 29 farmsExpand
Neospora caninum seropositivity in cattle breeds in the South Fluminense Paraíba Valley, state of Rio de Janeiro
TLDR
The hypothesis that there is a close association between cattle breeds and the frequency of infection by N. caninum is supported, as well as a high association between seropositivity and racial patterns was found. Expand
Coccidia of New World passerine birds (Aves: Passeriformes): a review of Eimeria Schneider, 1875 and Isospora Schneider, 1881 (Apicomplexa: Eimeriidae)
TLDR
The coccidia of 83 eimeriid species were organised and grouped according to the family of the host, following the widely recognised concept of family-specificity and the updated systematics of the class Aves. Expand

A new coccidian species (Protozoa: Apicomplexa: Eimeriidae) obtained from masked yellowthroat Geothlypis aequinoctialis (Gmelin) is reported from Brazil, the first description of an isosporoid cocCidian infecting a bird of the family Parulidae. Expand
Risk factors associated with Toxoplasma gondii infection in dairy cattle, state of Rio de Janeiro
TLDR
Univariate analysis of risk factors showed that cats in contact with cattle, cats incontact with drinking water, and number of cats were associated with T. gondii seroprevalence, and the presence of chickens was a protective factor. Expand
Oocyst shedding by green-winged-saltator (Saltator similis) in the diagnostic of coccidiosis and Isospora similisi n. sp. (Apicomplexa: Eimeriidae).
TLDR
It was concluded that the sampling in the late afternoon provided greater reliability for the diagnosis of coccidiosis in green-winged-saltators and a new isosporoid coccidium infecting S. similis was observed and is herein described. Expand
