Presencia de Babesia canis en perros del sector urbano Mata de Cacao de la Parroquia Febres Cordero del Cantón Babahoyo, Los Ríos, Ecuador

Canine babesiosis is a parasitic condition caused by Babesia canis and B. gibsoni, with B. canis being the most relevant species (Galindo, 2020), whose vector of this disease is the brown tick (Rhipicephalus sanguineus). Babesia protozoa live within cells that are intracellular, they feed on blood that is, they are hematophilic, they change shape pleomorphic (the most common, similar to a pear), bacillary (comma-shaped) oval-rounded (shaped oval or round) and annular (ring-shaped), there is also reproduction where there is binary fission (they divide into two daughter cells) and schizogony (they divide into multiple daughter cells within a mother cell). Babesia canis multiply in blood vessels, either inside or outside red or white blood cells, these parasites cause adverse impacts on the health of animals causing acute, subacute, chronic or latent infections, has a high rate of morbidity and mortality worldwide, most of the reported cases are in Europe and North America (ESSCCAP, 2012), in Ecuador there were some shortages. of data on this hemoparasite, however, the first cases of babesia canis were recorded in Guayaquil, Manabí, Chimborazo, Los Ríos and Santa Elena according to (Balao da Silva, Orlando Narvaez, & Campos Quinto, 2011 - 2014). For this research work, the objective will be to determine the presence of Babesia canis in dogs from the Mata de Cacao urban sector of the Febres Cordero Parish of the Babahoyo Los Ríos Canton, Ecuador. 80 animals were used to take the samples, where 1 ml was extracted directly from the cephalic vein and then placed in a lilac-topped tube to prevent coagulation. In the laboratory, the blood smear was taken and fixed with Giemsa and for a better view in the microscope used immersion oil. Prior to the results obtained in this research work, it was found that there is a higher prevalence of Babesia canis in males with (53%, 16 males) compared to females, which only had (47%, 14 females). This indicates that males are more likely to contract this hemoparasite.

La babesiosis canina es una afección parasitaria originada por Babesia canis y B. gibsoni siendo B. canis la especie más relevante (Galindo, 2020), cuyo vector de esta enfermedad es la garrapata marrón (Rhipicephalus sanguineus). Los protozoos de la babesia viven dentro de las células que son intracelulares,se alimentan de la sangre es decir son hematófilos, cambian de forma pleomórficos (la más común, similar a una pera), bacilar (forma de coma)Oval-redondeada (forma ovalada o redonda) y anular (forma de anillo), también está la reproducción en donde está la fisión binaria (se dividen en dos células hijas) y la esquizogonia (se dividen en múltiples células hijas dentro de una célula madre). La babesia canis se multiplican en los vasos sanguíneos, ya sea dentro o fuera de los glóbulos rojos o blancos, estos parásitos provocan impactos adversos en la salud de los animales causando infecciones agudas, subagudas, crónicas o latentes, presenta altas tasa de morbilidad y mortalidad a nivel mundial, la mayoría de los casos reportados son en Europa y Norte América (ESSCCAP, 2012), en Ecuador existía unos escases de datos en este hemoparásito, sin embargo, los primeros casos de la babesia canis fueron registrados en Guayaquil, Manabí, Chimborazo, Los Ríos y Santa Elena según (Balao da Silva y otros, 2011 - 2014). Para presente trabajo de investigación se realizará como objetivo determinar la presencia de Babesia canis en perros del sector urbano Mata de Cacao de la Parroquia Febres Cordero del Cantón Babahoyo Los Ríos, Ecuador. Se utilizaron 80 animales para tomar las muestras, donde se extrajo 1 ml directamente de la vena cefálica luego se colocó en un tubo tapa lila para evitar su coagulación, en el laboratorio se realizó el frotis sanguíneo se fijó con Giemsa y para una mejor visión en el microscopio se utilizó el aceite de inmersión. Previo a los resultados obtenidos en este trabajo investigativo se obtuvo que hay una mayor prevalencia de babesia canis en machos con un (53%, 16 machos) en comparación con las hembras que solo hubo un (47%, 14 hembras). Esto indica que los machos tienen mayor probabilidad de contraer este hemoparásito.
