Ocorrência e fatores de risco associados às infecções por Toxoplasma gondii e Neospora caninum em cães no município de Natal, Estado do Rio Grande do Norte, Nordeste do Brasil

Abstract: O objetivo do presente trabalho foi determinar a frequência de anticorpos anti-Toxoplasma gondii e anti-Neospora caninum, bem como identificar fatores de risco em cães do município de Natal, Estado do Rio Grande do Norte, Nordeste do Brasil. Para tanto, foram colhidas amostras de sangue de 476 cães atendidos em clínicas veterinárias no período de março de 2011 e maio de 2012. Para o diagnóstico sorológico das infecções, foi utilizada a reação de imunofluorescência indireta (RIFI), adotando-se como pontos de co… Show more

“…The IFAT results show clearly that there was a higher risk of infection with increasing age, especially among dogs older than 2 years, even though there was no statistical association. These results emphasize that the likelihood of infection increases with the dogs' ages and is in agreement with previous studies (CÃNÓN-FRANCO et al, 2004;DANTAS et al, 2013;LANGONI et al, 2013). In the present study, there was a significant difference regarding dogs seropositive for T. gondii between those with and without a defined breed (p<0.05), which was in agreement with Moura et al (2009).…”

“…The high frequency of anti-T. gondii antibodies in dogs (63.7% according to ELISA and 57.4% from IFAT) observed in this study corroborates other Brazilian findings: Minervino et al (2012) in Mato Grosso (52%), Valadas et al (2010) in Pará (69.8%) and Cañón-Franco et al (2004) in Rondônia (76.4%). However, lower values for anti-T. gondii antibodies were observed in other Brazilian states, by Dantas et al (2013) in Rio Grande do Norte (11.5%) and Lopes et al (2011) in Piauí (18%). The data corresponding to the frequency of T. gondii in Brazil are discordant, which may be related to different serological tests, sample sizes, types of dog population (DUBEY & SCHARES, 2011).…”

“…Contact with soil and pets was regarded as an important risk factor for T. gondii infection, which also affects about 65% of pregnant women in this region [16][17][18]. These data are consistent with reports from other Brazilian regions [5,[19][20][21].…”

“…Estudos recentes no Brasil mostram uma variação na frequência de soropositividade para T. gondii em cães de 11,50% a 88,52% (16)(17)(18)(19)(20)(21) . Essa variação de resultados pode estar relacionada às diferentes técnicas utilizadas e pontos de corte.…”
