Antibodies against Ehrlichia canis were detected, through a descriptive study, of cross and observational type, in 35 canine specimens of different breeds, with a history of infestation by Rhipicephalussanguineus, in the main town of Acayucan, Veracruz; situated in 17°56’55’’N and the 94°54´54´´W at 301 ft. above sea level. Complete blood samples were obtained for the detection of antibodies using the quick immune-migration test (Witness® Erlichis, Laboratory Symbiotic). 10 diseased animals were tested (Group 1), with at least one clinical sign associated to E. canis, cared for in two clinics of the same town and at simple random 25 healthy animals (Group 2). In the group of the diseased specimens 30% were detected positive and in the group of healthy animals an 8% was observed. In the total population, 14% was found positive to E. canis. The statistical analysis executed by the means of a software Epi-Info™, with data of Odds ratio, and of Χ2, demonstrated as a relative risk factor associated to E. canis, the size of the breeds in group one (OR 1.5, X2<1) and to the phase by their age, in both groups (Group one OR 1.667, X2<1 and Group two OR 1.36, X2<1). There were no significant differences (P≥0.05), regarding the breed, age, gender, habitat, or previous clinical condition, diseased or healthy specimens.
Se detectaron anticuerpos contraEhrlichia canis, mediante un estudio descriptivo, de tipo transversal y observacional, en 35 ejemplares caninos de diferentes razas, con antecedentes de infestación por Rhipicephalussanguineus, en la cabecera municipal de Acayucan, Veracruz; situada entre los 17°56’55’’N y los 94°54´54´´O a 92 msnm. Se obtuvieron muestras de sangre completa para la detección de anticuerpos por la prueba de inmuno-migración rápida (Witness® Erlichis, Laboratorio Synbiotics). Se muestrearon 10 animales enfermos (Grupo 1), con al menos un signo clínico asociado a la E. canis, atendidos en dos clínicas veterinarias de la misma localidad y en forma aleatoria simple 25 animales sanos (Grupo 2).En el grupo de enfermos se detectó el 30% de positivos y en el de animales sanos se observó un 8%. En la población total, el 14% se encontraron positivos a E. canis. El análisis estadístico efectuado mediante el programa Epi-Info™, con las pruebas de Odds ratio, y de Χ2, demostró como factores de riesgo relativo asociado a E. canis, a la talla de la raza en el grupo uno (OR 1.5, X2<1) y a la etapa por edad, en ambos grupos(Grupo uno OR 1.667, X2<1 y Grupo dos OR 1.36, X2<1). No hubo diferencias significativas (P≥0.05), respecto a raza, edad, sexo, hábitat o condición clínica previa, enfermos o sanos.
