The transmission of human strongyloidiasis occurs by penetration of
infective larvae (L3) in intact skin or mucous membranes. A characteristic
of the cycle involves the possibility of autoinfection. This mode of
infection increases the parasitic load of infected individuals, being responsible
for the long maintenance of the parasite in the host and is
characterized as the main factor for the development of severe forms
of strongyloidiasis as hyperinfection. Immunocompromised individuals
by different causes may develop hyperinfection characterized by
pulmonary and gastrointestinal hemorrhage, secondary bacterial and
fungal infections due to larvae spreading from the gut to other organs,
which may lead to a high mortality rate [4].
Studies conducted in the city of Uberlândia, Minas Gerais State,
Brazil, demonstrated that human strongyloidiasis are associated
