ABSTRACT
The seropositivity and risk factors for Trypanosoma cruzi infection in dogs from a municipality of Cundinamarca, a central state of Colombia were studied. A total of 356 client-owned dogs from urban, peri-urban and rural areas of La Mesa municipality, (Cundinamarca, Colombia) were randomly selected. Blood samples were collected by venipuncture. Anti-T. cruzi antibodies were determined using the enzyme-linked immunosorbent assay (ELISA) method. Reactive ELISA sera were processed by indirect immunofluorescence to confirm the presence of anti-T. cruzi antibodies. Chi-square tests were conducted for statistical analysis. Serologic tests for T. cruzi infection showed a prevalence of 29.49% (105/356), the rural area show a highest T. cruzi infection pattern in comparison with the other zone locations. Two triatomine species were found through the study: Panstrongylus geniculatus (53.4%) and Rhodnius colombiensis (46.6%). The prevalence of positive vectors for parasite was of 52.1% (38/73). Additionally, a very close relation between triatomine bugs and dogs in the rural zone (1:3.1) was observed. These results are the first report of natural infection by T. cruzi in domestic dogs in La Mesa municipality. In conclusion, the presence of anti-T. cruzi antibodies in dogs in this area suggest vector transmission. There is a need for active surveillance programs throughout the La Mesa municipality and vector control strategies should also be implemented.

En el presente trabajo se evaluó el efecto del uso de un producto inmunomodulador, preparado con Lipopolisacárido de E. coli y células inactivas de Propionibacterium granulosum, y aplicado a yeguas en la última fase de la gestación. Se evaluó en los potros las concentraciones de IgG e IgM depués del consumo de calostro y se determinaron los parámetros de morbimortalidad neonatal y pesos al nacimiento y al destete. Se obtuvo un efecto positivo general con el uso del producto bajo las condiciones en las que se realizó el estudio...
