Mold management of wetted carpet.

This study evaluated the growth and removal of fungi on wetted carpet using newly designed technologies that rely on physical principles of steam, heat, and fluid flow. Sixty samples of carpet were embedded with heat-treated house dust, followed by embedding, wearing with a hexapod, and wetting. Samples were inoculated using a liquid suspension of Cladosporium sphaerospermum prior to placement over a water-saturated foam pad.

Inactivation of dust mites, dust mite allergen, and mold from carpet.

Carpet is known to be a reservoir for biological contaminants, such as dust mites, dust mite allergen, and mold, if it is not kept clean. The accumulation of these contaminants in carpet might trigger allergies or asthma symptoms in both children and adults. The purpose of this study is to compare methods for removal of dust mites, dust mite allergens, and mold from carpet.

Fungi and allergic lower respiratory tract diseases.

Asthma is a common disorder that in 2009 afflicted 8.2% of adults and children, 24.6 million persons, in the United States.

Hypersensitivity pneumonitis secondary to residential exposure to Aureobasidium pullulans in 2 siblings.

Background: Hypersensitivity pneumonitis (HP) is an immune-mediated hypersensitivity reaction to a variety of inhaled particles that may lead to acute, subacute, or chronic interstitial pneumonitis and possibly end-stage lung disease. Avian antigens most commonly cause HP in children, but fungi have also been implicated.

Objective: To describe a 15-year-old girl and her 6-year-old brother who developed HP from residential exposure to Aureobasidium pullulans.
