ABSTRACT:
[b]Introduction and objective.[/b] [i]Toxoplasma gondii [/i]and [i]Neospora caninum[/i] are protozoans involved in reproductive failure especially in ruminant livestock. The objective was to estimate the seroprevalence of both parasites in goats from north-western Spain and to study the influence of some factors on seropositivity. [b]Materials and method.[/b] Blood samples from 638 goats were collected in 50 farms. Presence of [i]T. gondii[/i] and [i]N. caninum[/i] antibodies were detected by direct agglutination and competitiveELISA techniques, respectively. The risk factor analysis was performed using a mixed-effects logistic regression. [b]Results. [/b]Individual (48%) and herd-level (74%) [i]T. gondii [/i]seroprevalence values were high; the within-herd prevalence was 53%. In contrast, 6% of animals tested positive to [i]N. caninum [/i]and 38% of the herds had at least one positive animal, with a true within-herd prevalence of 10%. Mixed infections were limited; 91% of [i]N. caninum[/i] seropositive goats were also positive to [i]T. gondii.[/i] The risk factor analysis showed that [i]T. gondii [/i]seroprevalence is influenced by the presence of sheep in the farm (OR=4.9) and the seropositivity to [i]N. caninum[/i] (OR=16.5); goats from the Central-coastal area, more humid and warm, had a 15.7-fold probability of being seropositive to [i]T. gondii[/i] than those from the Mountainous area. Cross-breed goats (OR=4.5) and the seropositivity to [i]T. gondii [/i](OR= 9.5) were factors associated with [i]N. caninum[/i] seropositivity. [b]Conclusions. [/b]The high [i]T. gondii [/i]seroprevalence in goats constitute a noticeable zoonotic risk. The consideration of the risk factors identified in designing [i]T. gondii[/i] and [i]N. caninum[/i] control programs in goat herds should allow the implementation of more efficient measures, avoiding the appearance of outbreaks of reproductive disorders by both protozoans in goats.
