Detección de anticuerpos contra Anaplasma spp. en el perro “Ganacho” del Bosque Seco del Sur del Ecuador

Anaplasmosis is an infectious disease caused by bacteria of the genus Anaplasma, which can affect canines through vectors such as ixodid ticks. It leads to hematological changes like anemia and thrombocytopenia, as well as immunological alterations. This condition can also develop asymptomatically and slowly decimate a canine population, thus becoming a relevant problem in the health of “Ganachos” dogs in the dry forest of southern Ecuador. The present study was carried out in several cantons belonging to the seasonal dry forest ecosystem within the province of Loja (Zapotillo, Calvas, Gonzanamá, Paltas, Chaguarpamba, and Olmedo), whose general objective was to estimate the frequency of antibodies against Anaplasma spp. through the ELISA laboratory test (ANAVT0850 Test - 96 Determinations), The sample extracted was a total of 88 Creole canines that were dedicated to grazing goats, sheep, and cattle. Variables such as age, sex, size, coat color, and altitude were analyzed. Based on these data, a statistical analysis was made for the association of variables with the help of the exact Chi-square test, where 42 of the 88 samples analyzed were positive, obtaining a prevalence of canine anaplasmosis in this population of dogs of 47.7%. The results indicate that, among the incidence factors, only the size of the animal is statistically significant (p=0.042), with medium-sized canines being the most predisposed to this hemotropic disease.
