We used microscopy and molecular biology to provide the first documentation of infections of Myxobolus cerebralis (Myxozoa: Myxobolidae), the etiological agent of whirling disease, in trout (Salmonidae) from North Carolina (USA) river basins. A total of 1085 rainbow trout Oncorhynchus mykiss, 696 brown trout Salmo trutta, and 319 brook trout Salvelinus fontinalis from 43 localities across 9 river basins were screened. Myxospores were observed microscopically in pepsin-trypsin digested heads of rainbow and brown trout from the Watauga River Basin.

- An emergent fungal disease called lethargic crab disease (LCD) has significantly harmed the mangrove crab populations in Brazil since 1997, impacting both the ecosystem and local economies.
- Research suggests the black yeast Exophiala cancerae is responsible for these outbreaks, potentially dispersing through marine currents.
- Experimental results indicate that while salinity levels don't greatly affect its growth, prolonged exposure increases colony growth, and extreme temperatures negatively impact it, highlighting the importance of monitoring this fungus in coastal environments for better understanding of its spread.
