Resumen
Un estudio complementario a
otro similar que se había realizado
en el 2015 por la Escuela de Medicina Veterinaria de la Universidad
Nacional (UNA), para estudiar la
infección del mal de Chagas en los
perros de los pobladores de Getsemaní, determinó que el ciclo de
transmisión aún se mantiene activo en los perros, por lo que las especialistas hacen un llamado para
reforzar la mitigación de criaderos
del chinche que transmite el parásito causante de la enfermedad en
caninos y humanos.
En el 2015 se diagnosticaron 16
perros infectados con el parásito y
22 seropositivos (con anticuerpos
contra el parásito), de un total de
289 que fueron examinados. Además, de las 177 casas inspeccionadas, en 21 se encontraron vectores
(Triatoma dimidiata) infectados
con el parásito (Trypanosoma cruzi)
y en 14 de estas viviendas se encontró el vector anidando.
Las investigadoras Gaby Dolz,
Andrea Urbina y Marta Bonilla
de los laboratorios de Zoonosis y
Medicina Poblacional de la UNA
manifestaron que, en esta oportunidad, se examinó un total de 55
perros durante 16 meses. De estos,
25 perros vivían en casas en donde
se había determinado previamente
la presencia del chinche y 30 perros
en viviendas en donde no se habían
encontrado chinches. Durante el
periodo de estudio, se encontraron
seis casos de nuevas infecciones en
caninos. Todos los casos nuevos se
detectaron en hogares con antecedentes de presencia del vector
A complementary study to another similar one that had been carried out in 2015 by the School of Veterinary Medicine of the National University (UNA), to study the infection of Chagas disease in the dogs of the inhabitants of Getsemaní, determined that the transmission cycle is still active in dogs, so the specialists call for the reinforcement of the mitigation of bedbug breeding sites that transmit the parasite that causes the disease in canines and humans. In 2015, 16 dogs were diagnosed infected with the parasite and 22 seropositive (with antibodies against the parasite), out of a total of 289 that were examined. In addition, of the 177 houses inspected, vectors (Triatoma dimidiata) infected with the parasite (Trypanosoma cruzi) were found in 21 and in 14 of these houses the vector was found nesting. Researchers Gaby Dolz, Andrea Urbina and Marta Bonilla from the Zoonosis and Population Medicine laboratories of UNA stated that, in this opportunity, a total of 55 dogs were examined during 16 months. Of these, 25 dogs lived in houses where the presence of bedbugs had been previously determined and 30 dogs lived in houses where no bedbugs had been found. During the study period, six cases of new canine infections were found. All new cases were detected in homes with a history of bedbug presence.
