Strongyloidosis is an important health hazard, even in developed countries
due to the possibility of autoinfection leading to hyperinfection and
disseminated infection. Coproparasitological studies of strongyloidosis in
large populations are not easily perfomed, because the isolation of larvae
is better obtained with great amounts of fresh stools, based on the
hydrothropism of live larvae. Since the original description of the
Baermann method in 1917, several adaptations have been reported.
