The objective of this study was to use chlamydospores of the fungus Pochonia 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...
