Species of Helminthosporium are best known as parasites of cereals and grasses. It is frequently isolated from grains, grasses, sugar cane, soil and textiles.

Clinical Experience

Of 110 pediatric patients, in the Washington D.C., USA area with symptoms of rhinitis and/or asthma, 38% had positive skin test to Helminthosporium (Howard in 1 p150). Collins-Williams and coworkers reported on nasal provocation testing with molds in 150 children with perennial rhinitis and found that positive reactions were obtained in 32% to Helminthosporium (Reviewed in 1 Kozak & Hoffrnan, p170). Allergic bronchopulrnonary mycosis with Helminthosporium has also been reported (2).
