dc.description | Echinostoma paraensei is a trematode of the genus Echinostoma that causes echinostomiasis in humans.
The objectives of this study were to: evaluate the ovicidal activity of the nematophagous fungus Pochonia
chlamydosporia (VC1 and VC4) on a solid medium 2% water–agar (2% WA) against E. paraensei eggs (assay
A); evaluate ovicidal effect (destruction of eggs) of the isolate VC4 in supplemented culture media (assay
B); and evaluate the ovicidal ability of the crude extract (VC4) on E. paraensei eggs (assay C). Eggs of
E. paraensei (assay A) were placed in Petri dishes containing 2% WA with an isolate of the fungus P.
chlamydosporia (VC1 and VC4) grown for 10 days, and without fungus as a control and evaluated regarding
their destruction. In assay B, eggs of E. paraensei were placed in Petri dishes with different supplemented
culture media and with VC4 isolate and the destruction of eggs was examined at the end of 25 days of
interaction. In assay C, effects of the crude extract of P. chlamydosporia (VC4) on eggs were evaluated at the
end of 7 days. In assay A, there was no difference (p > 0.05) in ovicidal activity among the tested isolates
(VC1 and VC4); however, the highest percentage for ovicidal activity (type 3 effect) was demonstrated by
the isolate VC4. In assay B, the culture medium starch–agar showed the best results for the destruction
of the eggs, with a percentage of 46.6% at the end of the assay. In assay C, the crude extract of VC4 was
effective in the destruction of E. paraensei eggs, with a percentage reduction of 53%. The results of this
study demonstrate that a rich culture medium with a greater availability of carbon and nitrogen may
interfere directly in the predatory characteristics of ovicidal fungi. | |
