We report the case of a 60-year-old man who was receiving immunosuppressive therapy for a bilateral lung transplant and presented with a crusted, violaceous plaque on the left hand. Based on histopathology and microbiological culture the patient was diagnosed with infection by Alternaria species. Treatment with itraconazole led to complete resolution of the skin lesion. Forty months later he de...

BACKGROUND Fungal infections of self-sealing corneal incisions in cataract surgery are scarce. We report a case of Alternaria keratitis, several weeks after uneventful clear-cornea phacoemulsification. FINDINGS A 42-year-old woman, with a history of retinitis pigmentosa, complained of painful red right eye, 45 days after uneventful self-sealing clear-cornea phacoemulsification. Slit-lamp exam...

A mold survey in and out of the homes of 145 allergy patients was conducted over the course of a year and frequency of mold recovery was correlated with skin test reactivity in 131 of these patients. The highest percentage correlation with positive skin test and finding mold in the home was with Cladosporium. Penicillium and Alternaria, while Helminthosporium, Fusarium, Aureobasidium (Pullulari...

Overview Each year the commercial carrot crop in Wisconsin suffers losses from alternaria leaf blight, cercospora leaf spot, and aster yellows. The first two are diseases caused by fungi (Alternaria dauci and Cercospora carotae). The third is a disease caused by the aster yellows phytoplasma, a parasitic bacterium of carrot phloem tissue and also of the aster leafhopper (Macrosteles quadrilinea...

Alternaria (Hyphomycetes) A common saprobe found on decaying wood, decaying plants, food, soil, and outdoor air. Some species are plant pathogens. Indoors, it can be found in house dust, carpet, damp areas around showers and window frames, and anywhere condensation occurs. Because of its abundance and ubiquity, Alternaria is one of the most important fungal allergens and is recognized as the ch...

The antimicrobial activity and the MIC values of the ethanol, chloroform, diethyl ether, and acetone extracts of the chemical races of Pseudevernia furfuracea (var. furfuracea and var. ceratea) and their physodic acid, chloroatranorin, atranorin, and olivetoric acid constituents have been investigated against some microorganisms. Nearly all extracts of both chemical races showed antimicrobial a...

Alternaria blight is an important foliage disease caused by Alternaria solani. The enzyme Succinate dehydrogenase (SDH) is a potential drug target because of its role in tricarboxylic acid cycle. Hence targeting Alternaria solani SDH enzyme could be efficient tool to design novel fungicides against A. solani. We employed computational methodologies to design new SDH inhibitors using homology mo...

Alternaria leaf blight is a much greater threat to muskmelons than watermelons. The disease is caused by a fungus (Alternaria cucumerina) that can rapidly defoliate plants, causing reductions in bulk yield. Melons on defoliated vines ripen prematurely and result in lower quality fruit compared to melons produced on healthy vines. Yield losses greater than 50% will occur in situations where the ...
