EFFECT OF DIFFERENT ECOSYSTEMS AND MANAGEMENT PRACTICES ON TOXOPLASMA GONDII AND NEOSPORA CANINUM INFECTIONS IN WILD RUMINANTS IN SPAIN

Toxoplasma gondii and Neospora caninum are two major abortifacient protozoans in domestic small ruminants and cattle, respectively, and they also parasitize a wide range of wildlife. Numerous serosurveys have been conducted in wild ruminants worldwide. However, the potential effect of different ecosystems and management practices on these infections has not been investigated. We studied the prevalence of antibodies to T. gondii and N. caninum in wild ruminants between 2007 and 2012 from four national wildlife reserves: three open space reserves in northwest Spain (Ancares, Mampodre, and Riaño) and a fenced reserve in central Spain (Quintos de Mora). Sera from roe deer (Capreolus capreolus) and chamois (Rupicapra rupicapra) were collected in Ancares (roe deer), Mampodre (both species), and Riaño (both species), whereas red deer (Cervus elaphus) sera were collected only in Quintos de Mora. The results of immunofluorescence antibody tests showed a T. gondii antibody prevalence significantly higher in red deer (13%; 17/131) than in roe deer (2%; 5/228) and chamois (4%; 6/149) (P
