dc.descriptionThe presence of Ehrlichia canis was detected in 1935, by Donatien and Lestoquard of the Pasteur Institute of Algeria, because they visualized organisms similar to rickettsiae in monocytes from febrile and anemic dogs, which is why they were classified as Rickettsia canis. In 1945, Moshovski reclassified them as Ehrlichia canis in honor of Paul Ehrlich, a German bacteriologist, establishing a genus different from Rickettsia. The etiological agent of Ehrlichia is an obligatory intracellular, gram-negative, coccoid-shaped bacteria that requires a mammal as a reservoir and an arthropod as a vector, which affects blood cells. Its main vector is the Brown Tick or Rhipicephalus sanguineus. The objective of this research work was to determine the presence of Ehrlichia through blood smears in the dogs of the La Mascota Campus, which is located in the Montalvo Canton, Los Ríos Province. 50 blood samples from the study dogs were used, according to age, sex and breed, in order to find out how many animals have the disease. A blood sample of 1 to 2 ml is taken directly from the cephalic vein, then it is placed in a tube with EDTA to prevent coagulation, then a blood smear is taken to be stained with Wright's stain. to finally be observed under the microscope. After observing the 50 samples, 22 positive cases for Ehrlichia were obtained, where the mixed breed was more susceptible, as were adult males.es_ES

dc.description.abstractLa presencia de Ehrlichia canis se detectó en 1935, por Donatien y Lestoquard del Instituto Pasteur de Argelia, debido a que visualizaron en monocitos de perros febriles y con anemia, organismos semejantes a rickettsias, por lo que fueron clasificados como Rickettsia canis. En 1945, Moshovski los reclasificó como Ehrlichia canis en honor a Paul Ehrlich, bacteriólogo alemán, con lo que se estableció un género diferente a Rickettsia. El agente etiológico de la Ehrlichia es una bacteria intracelular obligatoria, gram-negativa, de forma cocoide que requiere de un mamífero como reservorio y de un artrópodo como vector, que afecta a las células sanguíneas, su principal vector es la Garrapata Marrón o Rhipicephalus sanguineus. El presente trabajo de investigación tuvo como objetivo determinar la presencia de Ehrlichia mediante frotis sanguíneo en los perros del Recinto La Mascota, la misma que se encuentra en el Cantón Montalvo, Provincia Los Ríos. Se utilizaron 50 muestras sanguíneas de los perros de estudio, de acuerdo a la edad, sexo y raza, con el fin de averiguar cuantos animales presentan la enfermedad. Se procede a tomar una muestra de sangre de 1 a 2 ml, directamente de la vena cefálica, luego se procede a ubicar en un tubo con EDTA para evitar la coagulación, después se realiza un frotis sanguíneo para ser teñidas con la Tinción de Wright, para finalmente ser observadas en el microscopio. Después de observar las 50 muestras se obtienen 22 casos positivos a Ehrlichia en donde la raza mestiza fue más susceptible al igual que los machos adultos.es_ES
