Seroprevalence of Toxoplasma gondii and Neospora caninum in feral cats (Felis silvestris catus) in Majorca, Balearic Islands, Spain.

Felids are important in the epidemiology of Toxoplasma gondii infection because they are the only hosts that can excrete environmentally resistant oocysts. Antibodies to T. gondii and Neospora caninum were determined in serum samples from 59 feral cats (Felis silvestris catus) captured in baited traps during authorized predator control campaigns in Majorca, Balearic Islands, Spain.

Low seroprevalence of Neospora caninum infection associated with the limousin breed in cow-calf herds in Andorra, Europe.

Neospora caninum seroprevalence and risk factors affecting seroprevalence in beef cattle in Andorra were investigated. Antibodies to N. caninum were evaluated by enzyme-linked immunosorbent assay performed on a yearly basis in 1,758 animals older than 6 mo, belonging to 26 herds.

First report of Neospora caninum abortion in a beef cow-calf herd from Andorra, Europe.

Neospora caninum-associated abortion was diagnosed in a 7-mo gestational age beef cow fetus from Andorra. The fetus had a multifocal necrotizing encephalitis and nonpurulent multifocal myocarditis. The diagnosis was confirmed by demonstration of N.
