Resumo: The objective of this study was to use chlamydospores of the fungusPochonia chlamydosporia (isolates VC1 and VC4) against Toxocara canis eggs in a 15-day in vitro assay. One thousand T. canis eggs were placed in Petri dishes containing 2% water agar medium with different concentrations of chlamydospores (1,000, 10,000 or 100,000) of each fungal isolate of P. chlamydosporia (treated groups) and 1,000 eggs in Petri dishes without fungus (control group). Egg counts were performed to determine the ovicidal activity, which was classified as three effect levels: type 1, type 2 and type 3. Significant differences (P < 0.01) in egg destruction were found in comparison with the control group. The highest percentage of egg destruction was found in plates containing 100,000 chlamydospores (68.5% for VC1 and 70.5% for VC4). Chlamydospores of P. chlamydosporiawere effective in destroying T. canis eggs and may contribute in the future towards combating the eggs of this parasite.
