ENZYMATIC ACTIVITY OF THE FUNGUS Pochonia chlamydosporia (SORDARIOMYCETES: HYPOCREALES) AND ITS OVICIDAL POTENTIAL ON EGGS OF Toxocara canis (NEMATODA: ASCARIDIDA)

Biological control is considered one of the most used alternative measures to combat helminths relevance in veterinary medicine and public health. Among these parasites, Toxocara canis stands out for its high prevalence worldwide distribution, addition being main cause visceral larva migrans man. The present work aimed fungus Pochonia chlamydosporia (isolate Pc-10) on eggs T. canis. In order do this, fertile nematode were obtained by dissection adult females fertilized specimens. After obtaining eggs, they inserted into 24 well plates previously À lled with different concentrations enzymatic extract (100, 200, 400 500 ?L). addition, behavior P. hyphae was also observed 2% wateragar medium (2% WA+ fungal isolate) when compared group WA + water). It veriÀ ed ovicidal activity at ?L. At same time, after 12 days exposure mycelia it possible observe action eggshells, including penetration colonization egg inside. results conÀ rm potential suggest applicability toxocariasis programs.
