Ascogregarina culicis (apicomplexa: lecudinidae) en Aedes aegypti naturalmente infectado

Abstract

As activity surveillance system for controlling Aedes in the country, potential breeding sites were reviewed in several locations. By manual capture of mosquito larvae in 15 locations in five states of Venezuela, the infection was detected in 26.8% of a total of 750 larvae collected and identified as Aedes aegypti, using the taxonomic keys. Dissecting infected larvae allowed exposure tubes Malpii ghian and inside the digestive cavity, on a glass slide, it was possible to identify the presence of a microorganism of 90µm long and 24µm wide with a core located slightly the posterior pole of the organism, and mucron, easily distinguishable in the previous pole. Comma-shaped and has presented a very slow moving, they allowed identifying characteristics as a Ascogregarina culisis, parasitizing the digestive tract of Aedes aegypti, with possible pathogenic potential for your guest. It was possible to have more than two hundred parasites within one larva. In the same it was possible to observe several of the developmental stages of the parasite and to dissect tubes malpigio infected adults, it was possible to identify large numbers of spores or oocytes, which are the infectious form, completing the observation of the life cycle of the parasite.
