[The influence of the Metarhizium fungi on the embryonic development of Ascaris suum].
OBJECTIVE
The present study focused on the effect of two fungal species Metarhizium flavoviride and Metarhizium anisopliae on the embryonic development and viability of Ascaris suum larvae.


RESULTS
Microscope examination revealed that the presence of the mycelium inhibited the egg development, compared to control. The fungus-exposed eggs featured zygote vacuolisation, irregular blastomere cleavage, and morphological disturbances in the stages of blastula, gastrula, and larva. The embryopathies were significantly more frequent in the eggs incubated with M. flavoviride. Also the mortality of the developed larvae was significantly higher after 60-day culture with M. flavoviride.
