Resumo

An in vitro experiment was carried out to assess the effect of fungal isolates of the genus Arthrobotrys, Duddingtonia, Monacrosporium and Nematoctonus on infective Strongyloides papillosus larvae. A suspension of 1,000 infective S. papillosus larvae was dripped on to Petri dishes containing fungi grown in agar-water. There was a statistically significant difference (p<0.05) among all the isolates and the fungus-free control. Comparing the results between isolates, difference was observed in some isolates of the genus Arthrobotrys (CG 719, I40, A1, A2, C1, B1), D. flagrans (CG722), Monacrosporium (CGI, SF53, NF34A) and N. robustus (D1) that showed a better capture and destruction results and consequently a greater decrease in the average of the uncaptured larvae recovered. The results showed that there may be variations in the predatory capacity of different species and among fungal isolates of the same species on Strongyloides papillosus and indicated that nematophagous fungi may be used for the biological control of this helminth.(AU)
