In Vitro Development of Toxocara canis Nematode Eggs

This study aims to describe the morphological changes of the embryo inside the developing egg during incubation in vitro at 30 °C, as well as to study the differences in the viability of the eggs during the incubation period. T. canis eggs were placed in a thermostat for incubation at 30 °C in an isotonic solution of 0.9% sodium chloride for eleven days. Development, morphological changes and viability of 100 eggs were observed. No significant differences were found in recorded viability from day first to day eleventh of incubation.
