Cães sororreagentes a Neospora caninum Dubey, Carpenter, Speer, Topper e Uggla, 1988 (Apicompexa: Toxoplasmatinae) na Barra da Tijuca, região metropolitana do Rio de Janeiro

Abstract

A total of 402 serum samples obtained from dogs of a Veterinary Intensive Care Unit (CTI Veterinário), over a period of 18 months, located in Barra da Tijuca, metropolitan region of Rio de Janeiro, RJ., were used to determine the presence of animals seropositive to N. caninum and determine the variables that could be associated with the presence of etiological agent in dogs of the studied region. The presence of seropositive animals to IFAT for N. caninum was 8.46% (34/402) where the age was infection risk factor, given that this in animals with age ranging from three months to 19 years, but with the vast majority of over 10 years, and the animals that lived in the apartment were twice as protective factor. However, the small animals were the most seropositive infection by N. caninum. Although two of the animals show neurological sigs cannot correlate them with the infection by N. caninum seropositive to be positive; indicating that animals with neuropathies necessarily are not linked to neosporosis. By the results observed close relationship between natural infection and the age of the animals, but one should not underestimate the gender and feed in the dispersal of N. caninum among dogs of the studied region, which is the first mention of the presence N. caninum in the State of Rio de Janeiro, Brazil.
