Prevalencia de microfilaria spp. en caninos mayores de 6 meses en la ciudad de huaquillas

Abstract

It is called Dirofilaria immitis to a parasitic nematode of the dog, which affects several species both domestic and wild, even in rare cases it can affect humans. Filariae can be located in the blood, in the subcutaneous tissue and in cavities. These nematodes when taking larval form become Microfilaria, the same that when ingested by hematophagous mosquitoes infect animals and people through their bite. Detection of microfilariae provides definitive evidence of filarial infection. Furthermore, the size and morphology of the microfilariae can be used to differentiate between different species of filariae. However, many patients with microfilaremia do not have symptoms or signs of clinical filariasis, and many patients with clinical filariasis do not have microfilaremia. Furthermore, the size and morphology of the microfilariae can be used to differentiate between different species of filariae. However, many patients with microfilaremia do not have symptoms or signs of clinical filariasis, and many patients with clinical filariasis do not have microfilaremia. Furthermore, there is no relationship between blood microfilariae counts and disease severity. Microfilariae are usually present in the hydrocele fluid, and sometimes they are also present in urine or other body fluids. The life cycle begins when a female mosquito bites an infected dog and ingests the microfilariae during a blood meal. The microfilariae further develop for 10 to 30 days in the mosquito's gut and then enter its mouthparts. At this stage, they are infective larvae and can complete their maturation when they enter a dog. The infective larvae enter the dog's body when the mosquito bites it. When a dog is infected, adult female heartworms release their young, called microfilariae, into the dog's bloodstream. Microfilariae must pass through a mosquito to develop into infective larvae. When the infected mosquito bites another dog, the mosquito transmits the infective larvae to the dog through the bite wound. The present study was carried out in order to determine the prevalence of microfilaria sp. in domestic dogs from the main neighborhoods of the city of Huaquillas, where 230 dogs of both sexes, small, medium and large breeds, from 6 months of age onwards were examined in the five parishes of this city. The study was carried out in the months of July to December. Method: For this field study, the observational descriptive method was used since each of the variables selected in the investigation will be described and observed. Results: The samples were analyzed using the fresh drop and microcapillary method, where it was possible to show that there is a prevalence of microfilaria sp. of 6%, and it was also possible to determine that the variables of sex, origin, race and age do not influence in any way the acquisition of the disease. As a recommendation in this project, it is suggested that to avoid infestation in pets it is preferable that they be kept under surveillance when they are in external areas, that they live inside the home or that the development of the vector is controlled in situ, and that the owners carry out a Check your pets at least once a year.
