Isolation and molecular identification of pathogens causing sea turtle egg fusariosis in key nesting beaches in Costa Rica

mycolabadmin

Scientists discovered that two harmful fungi, Fusarium falciforme and Fusarium keratoplasticum, are present on sea turtle nesting beaches across Costa Rica. These fungi can infect turtle eggs and cause high mortality rates in developing embryos. The researchers used advanced genetic techniques to accurately identify these pathogens and found them widespread at important nesting sites, highlighting the need for monitoring and protection strategies to prevent this emerging disease from becoming a major threat to sea turtle populations.

Trachemys scripta Eggs as Part of a Potential In Vivo Model for Studying Sea Turtle Egg Fusariosis

mycolabadmin

Sea turtles around the world face a serious threat from a fungal disease called fusariosis that destroys their eggs before they hatch. Scientists wanted to study how this fungus causes disease, but working with endangered sea turtles in tropical regions is difficult and heavily regulated. They discovered they could use eggs from red-eared slider turtles, an invasive species, as a substitute model to understand how the fungus infects eggs. The research showed that the fungus is highly virulent and modifies the acidity of egg surfaces to help it grow, providing valuable insights that could help protect endangered sea turtles.
