Code: m16
Latin name: Curvularia lunata
Source material: Spores and mycelium
There appears to be extensive cross-reactivity between Stemphylium and Curvularia and Alternata (3).

Allergen Exposure

Curvularia is a facultative pathogen and may cause leaf spots and seedling blight. It is also seen on castor beans, cotton, rice, barley, wheat, and corn.

Potential Cross-Reactivity

There appears to be extensive cross-reactivity between Stemphylium and Curvularia and Alternata (3).

Clinical Experience

Curvularia is a mold which is associated with allergy in the literature and frequently reported in mold spore counts. Chapman & Williams (1) reported 7.3% of the atopic patients being hypersensitive to Curvularia. Allergic bronchopulmonary disease caused by Curvularia has been reported (2).
 
Review
C. lunata is reported from numerous, mostly monocotyledonous host plants in many tropical countries but also from Canada, the British Isles, France and the Netherlands. Curvularia is a facultative pathogen and may cause leaf spots and seedling blight. It is also seen on castor beans, cotton, rice, barley, wheat, and corn.
