“…Several studies are showing that infected dogs constitute a major domestic reservoir of T. cruzi and a risk factor for domestic transmission throughout Latin America (Gürtler et al, 2005Crisante et al, 2006;Estrada-Franco et al, 2006). Consequently, the regular screening of domestic dog populations for T. cruzi infection can be used to identify houses or clusters with infected dogs and high risk of transmission.…”

Impact of community-based vector control on house infestation and Trypanosoma cruzi infection in Triatoma infestans, dogs and cats in the Argentine Chaco

The relative impact of two community-based vector control strategies on house infestation by Triatoma infestans and Trypanosoma cruzi infection in bugs, domestic dogs and cats was assessed in two neighboring rural areas comprising 40 small villages and 323 houses in one of the regions most endemic for Chagas disease in northern Argentina. The prevalence and abundance of domestic infestation were 1.5-and 6.5-fold higher, respectively, in the area under pulsed, non-supervised control actions operating under the guidelines of the National Vector Control Program (NCVP) than in the area under sustained, supervised surveillance carried out jointly by the UBA research team and NCVP. The prevalence of infestation and infection varied widely among village groups within each area. In the pulsed control area, the prevalence of infection in bugs, dogs and cats was two-to three-fold higher than in the area under sustained surveillance, most of the infected animals qualified as autochthonous cases, and evidence of recent transmission was observed. Infection was highly aggregated at the household level and fell close to the 80/20 rule. Using multiple logistic regression analysis clustered by household, infection in dogs was associated positively and significantly with variables reflecting local exposure to infected T. infestans, thus demonstrating weak performance of the vector surveillance system. For high-risk areas in the Gran Chaco region, interruption of vectormediated domestic transmission of T. cruzi requires residual insecticide spraying that is more intense, of a higher quality and sustained in time, combined with community participation and environmental management measures.

“…In addition, in some regions, domestic animals such as dogs, have been found to play an important role as reservoir of the parasite and its transmission to human. [11][12][13][14] Control of infection in these animals has thus been proposed as an important complementary strategy to vector control, for example using insecticide-impregnated collars. 15 However, a veterinary vaccine, either preventive or therapeutic, would thus also greatly contribute to Chagas disease control by reducing infectiousness of the main domestic reservoir …”

“…Los perros en el domicilio fueron los responsables de una mayor infestación de los vectores recolectados. Asimismo, Estrada, et al (47), reportaron en la municipalidad de Tejupilco en el estado de México (México), una correlación directa (r 2 =0,955) de resultados positivos entre la infección por T. cruzi en humanos y perros. Esos resultados sugieren que puede haber una trasmisión bidireccional de perros a humanos y de humanos a perros, cuando hay vectores en los domicilios o peridomicilios.…”

No significant statistic association was found between the T. cruzi infection in dogs and the evaluated epidemiological variables: hunting dogs that slept oudoors roaming freely in the populated center, sex of the animal and eating habits. The T. cruzi infection was associated to the age of canines, being significantly higher in the group of 0 to 3 years, when compared with older dogs. ARTÍCULO ORIGINAL
