Frequência de anticorpos anti-Neospora caninum em cães nos municípios de Salvador e Lauro de Freitas, Estado da Bahia - Brasil

Abstract

A freqüência de anticorpos IgG anti-Neospora caninum foi estudada em 415 amostras séricas de cães domiciliados e errantes, procedentes dos municípios baianos de Salvador e Lauro de Freitas, utilizando-se a técnica de imunofluorescência indireta, com ponto de corte igual a 1:50. Anticorpos da classe IgG anti-N. caninum foram detectados em 13,3% (22/165) dos cães domiciliados e em 11,2% (28/250) dos errantes. As freqüências de soropositivos machos e fêmeas foram 8,0% (6/75) e 18,4% (14/76) nos cães domiciliados e 12,6% (17/135) e 9,6% (11/115) nos errantes, respectivamente. Não houve diferenças estatisticamente significativas entre sexo, idade, raça e a freqüência de soropositividade ao N. caninum dos cães domiciliados e errantes.

Seroprevalence of antibodies to Neospora caninum in dogs in the state of Alagoas, Brazil

“…According to the statistical analysis, there was also no significant difference (P = 0.749) between defined and undefined animal breeds, even when the defined breed presented 1.46 times more chances of becoming infected than the undefined breed. These results corroborate the findings of Romanelli et al (2007) and Jesus et al (2006), who also did not find any statistically significant difference in relation to breed among the animals studied, thus indicating that all breeds are equally susceptible to the agent.…”

“…With regard to sex, five males (4.0%) and five females (4.5%) were positive, and there was no statistically significant difference between the sexes, as was also described in the studies carried out by Oliveira et al (2004), Jesus et al (2006), Romanelli et al (2007), Benetti et al (2008) and Moraes et al (2008). Moreover, when this variable was subjected to univariate analysis (P = 0.859), there was no association with occurrences of anti-N. caninum antibodies, thus demonstrating that in this region, males and females can be equally stricken and are subject to the same risks of infection (BOAVENTURA et al, 2007;CUNHA FILHO et al, 2008).…”

Neospora caninum antibodies and risk factors in dogs from Lages and Balneário Camboriú, SC

“…Coskun et al (2000), in Turkey; Oliveira et al (2004), in Campo Grande, Brazil, and Haddadzadeh et al (2007), in Teheran, Iran, also did not observe association between gender and the prevalence of anti-N. caninum antibodies. Jesus et al (2006), in Bahia State, Brazil, did not find statistical difference among gender, age, and breed and the frequency of antibodies anti-N. caninum. Patitucci et al (2001), in Chile, observed higher positivity in dogs feed on domestic food.…”

“…Cañón-Franco et al (2003), studying urban dogs from Monte Negro, RO, observed 8.3% of positivity; while Oliveira et al (2004), in Campo Grande, MS, observed a seroprevalence of 26.5%. Jesus et al (2006), in the cities of Salvador and Lauro de Freitas, BA, found frequencies of 13.3% and 11.2% in domiciled and stray dogs, respectively. Teixeira et al (2006), in São Luís, MA, reported a frequency of 45% in dogs captured by the Centre for Control of Zoonoses.…”

Anticorpos para Leptospira spp., Toxoplasma gondii e Neospora caninum em cães errantes albergados em canil privado

“…Jesus et al (2006), ao trabalharem com cães domiciliados e errantes de Salvador e Lauro de Freitas, na Bahia, pela RIFI, detectaram 22 (13,3%) de positividade em animais domiciliados e 28 (11,2%) em animais errantes. A possibilidade de transmissão horizontal entre cães errantes na zona urbana e na zona rural pode ser maior devido à facilidade de ingestão de roedores, pássaros e outros animais que podem ser fontes de infecção.…”
