La prevalencia de infecciones transmitidas por garrapatas se desconoce en la mayor\u00eda de los pa\u00edses latinoamericanos, incluyendo a Venezuela. Objetivo. Estimar la prevalencia de infecciones transmitidas por garrapatas en humanos y en perros en Puerto Ordaz, estado Bol\u00edvar, Venezuela.Materiales y m\u00e9todos. Se realiz\u00f3 un estudio exploratorio, descriptivo y prospectivo. Se evaluaron 181 individuos que aceptaron participar en forma voluntaria y dieron su consentimiento informado por escrito, y 10 perros llevados por sus due\u00f1os. Se aplic\u00f3 una encuesta cl\u00ednico-epidemiol\u00f3gica y se tomaron muestras de sangre venosa y capilar. Se hizo un frotis de capa blanca y una extensi\u00f3n sangu\u00ednea, que luego fueron te\u00f1idos con Giemsa. Resultados. Se observaron infecciones transmitidas por garrapatas en el 85,1 % (n = 154) de los individuos. La m\u00e1s frecuente fue por Ehrlichia spp. (n = 153; 84,5 %), seguida de Babesia spp. (n = 39; 21,5 %) y Anaplasma spp. (n = 39; 21,5 %). Las mujeres fueron las m\u00e1s afectadas (n = 117; 64,6 %), con un rango de edad entre los 5 y los 97 a\u00f1os. El 29,3 % (n = 53) de los individuos infectados present\u00f3 coinfecci\u00f3n de Ehrlichia spp. y Babesia spp., mientras que el 6,4 % (n = 12) tuvo coinfecci\u00f3n por los tres agentes pat\u00f3genos estudiados. Todos los perros, diez en total, presentaron infecciones transmitidas por garrapatas: 10 por Ehrlichia spp., 5 por Anaplasma spp. y 5 por Babesia spp. Se encontr\u00f3 una asociaci\u00f3n estad\u00edsticamente significativa entre la presencia de garrapatas peridomiciliares \u2013favorecida por la falta de paseos a la mascota y la tenencia de perros enfermos o de edad avanzada \u2013y las infecciones transmitidas por garrapatas (p &lt; 0,05).Conclusiones.
