The book "Ovicidal Effect of Soil Fungi on Toxocara canis Eggs" offers a comprehensive investigation of the ovicidal properties of saprotrophic soil fungi on the eggs of Toxocara canis. The research focuses on samples taken from public parks in La Plata, Argentina. The authors, María Laura Ciarmela, Angélica M. Arambarri, and Marta Cecilia Minvielle, isolated various fungal species and examined their effects on T. canis eggs over a period of 28 days under controlled conditions. The results indicate that certain fungal species, such as Chrysosporium merdarium and Fusarium oxysporum, exhibit significant ovicidal activity, laying the groundwork for future studies on the mechanisms of egg destruction by these fungi. These findings could potentially contribute to the development of biological control methods against Toxocara canis, which is significant for public health.
