Determinación del estatus actual de la distribución geográfica de la Dirofilaria immitis en Canis lupus familiaris en la zona noroeste de la ciudad de Guayaquil en el año 2021.

Abstract

The objective of this study was to determine the current status of Dirofilaria immitis in the northwestern sector of the city of Guayaquil in the year 2021. Through various diagnostic techniques to determine microfilariae and dirofilariae, such as direct observation of blood smear, SNAP 4Dx test, Woo test, Knott test, echocardiography and buffy coat, it was possible to determine the seropositivity of the 105 dogs treated in the period from May to July 2021 in veterinaries in the northwestern sector of the city of Guayaquil, in order to sectorize the place of origin of the 18 positive cases, and, therefore, determine and define the epidemiological risk area of dirofilariasis. The age and sex variables were representative, since 10 of the 18 % of the positive cases were aged 7 years and older, and 62 % of those confirmed with dirofilariasis were males. It was proved that the origin of the dogs parasitized with Dirofilaria, lived in an area close to mosquito breeding sites where the vector population was found.
