ABSTRACT
El objetivo de este trabajo fue determinar la prevalencia a Neospora caninum (Nc) y Toxoplasma gondii (Tg) y conocer el periodo reproductivo de la liebre europea (Lepus europaeus) en la provincia de La Pampa (Argentina). Para ello se muestrearon 106 liebres procedentes de acopiadores de la provincia de La Pampa. Los sueros fueron analizados por un ensayo inmunoenzimático de competición para determinar anticuerpos a Nc y para Tg se realizó una prueba de hemaglutinación indirecta. Se encontraron 66 hembras, de las cuales 13 estaban preñadas, y 40 machos (p=0,01). Sobre un total de 44 sueros analizados para Nc, 5 (11,4%) dieron positivo. De los 106 sueros estudiados para Tg ninguno fue positivo.
The objective of this study was to determine the prevalence of these diseases and to know the reproductive season of the European hare (Lepus europaeus) in the Province of La Pampa (Argentina). To that aim, 106 hares coming from different places from La Pampa province were sampled. .Nc antibody diagnosis was performed by means of a competitive enzimoimmunoassay (ELISA-c), and an hemo-agglutination indirect assay (HAI) for Tg were carried out to know the disease status. From the total of hares sampled, 40 were male, 66 female (p=0.01) and 13 (19.7%) of them were detected as pregnant. Nc sero-prevalence was 11.4% over a total of 44. From 106 sera analyzed by HAI no one was positive for Tg.

Presence of T. gondii in meat from several sources was determined by traditional methods and by a new simplified method in wich animals are fed meat directly without any previous treatment with artificial gastric fluid. Tissues are ground and the animals ingest them naturally. Determination of Toxoplasma in lungs or brain (as well as by specific antibody test), showed no statistically significant differences between both methods.
