Abstract

Background: Canine dirofilariasis, is a vector-borne disease caused by the parasitic filarial nematode Dirofilaria immitis. Cardiopulmonary dirofilariasis is a worldwide distributed disease, affecting domestic as well as wild canines and felines and also causing pulmonary or cutaneous infections in humans. In recent years, scientists have reported the importance of investigating human cases of dirofilariasis since it can be easily confused with lung disease. Guatemala has a high density of canine population. Few studies have reported a high prevalence of canine dirofilariasis nevertheless, knowledge in Guatemala of Dirofilaria immitis is scarce and practically inexistent. Because of the previous reason, the decision to explore the circulation of antibodies against D. immitis in dogs in the southern part of Guatemala was made. Material and Methods: Data was recollected from 110 dogs above one year old of various races and both sexes, from the village “El Brito”, Escuintla. One milliliter of blood was collected from each dog; the samples were analyzed by ELISA test looking for the presence of antibodies of the adult warm. The data collected was registered in Excel 2016. Categorical variables were analyzed with frequencies and percentages. Results: The prevalence determined for antibodies against Dirofilaria immitis circulating the bloodstream of sampled canines was 2.7%, the most frequent age of the canines were 1-3 years old (85%). Conclusions: According with the data the prevalence of canine dirofilariasis in a southern region in Guatemala was low.
