Alternaria fruit rot

Alternaria tenuissima is a cosmopolitan species, common on an array of various plant hosts in many countries spanning a range of environmental conditions. It often colonizes blueberries, tomatoes, grapevine, and strawberries. It has also been found on several cereal grain species. Optimal growth occurs between 25–30 °C (77–86 °F). Although A. tenuissima is normally an opportunistic pathogen of plants, rare cases of skin infections in immunocompromised people have been reported.
