(+info)Lobomycosis is a chronic granulomatous fungal infection that primarily affects the skin and subcutaneous tissue. It is caused by the fungus Lacazia loboi, which is found in aquatic environments and is transmitted to humans through traumatic inoculation of the organism into the skin. The disease is characterized by the formation of warty, nodular or tumor-like lesions that can ulcerate and become secondarily infected. Lobomycosis mainly occurs in tropical and subtropical regions, particularly in Central and South America, and is more common in men than women. The infection often persists for many years and can cause significant disfigurement and disability. Treatment options are limited and include surgical excision, cryosurgery, and chemotherapy with antifungal agents such as itraconazole or posaconazole.
"Lacazia" is not a term that has a widely accepted medical definition in the context of human health. It is a genus of fungi that includes the species Lacazia loboi, which is known to cause a cutaneous infection called lobomycosis in humans and some animals. Lobomycosis is a chronic granulomatous disease that primarily affects the skin and subcutaneous tissue, leading to the formation of nodules, plaques, and scarring. However, it's worth noting that Lacazia loboi infections are rare in humans, and the disease is not well understood.
Onygenales is a taxonomic order of fungi that includes several medically important genera that can cause various infections in humans and animals. The most well-known members of Onygenales are dermatophytes, which are the causative agents of superficial mycoses such as ringworm, athlete's foot, and jock itch. Other medically important genera in Onygenales include Histoplasma, Blastomyces, Coccidioides, and Paracoccidioides, which can cause systemic mycoses that affect the lungs and other organs.
The order Onygenales is characterized by the production of ascomata (sexual fruiting bodies) that are typically covered by a layer of hyphal cells called an ascostroma. The ascomata produce asci, which contain ascospores, the sexual spores of these fungi. Some members of Onygenales also produce asexual spores called conidia, which can be produced in various ways depending on the genus and species.
Overall, Onygenales is an important order of fungi that includes many pathogens with significant medical relevance.
Dermatomycoses are a group of fungal infections that affect the skin, hair, and nails. These infections are caused by various types of fungi, including dermatophytes, yeasts, and molds. Dermatophyte infections, also known as tinea, are the most common type of dermatomycoses and can affect different areas of the body, such as the scalp (tinea capitis), beard (tinea barbae), body (tinea corporis), feet (tinea pedis or athlete's foot), hands (tinea manuum), and nails (tinea unguium or onychomycosis). Yeast infections, such as those caused by Candida albicans, can lead to conditions like candidal intertrigo, vulvovaginitis, and balanitis. Mold infections are less common but can cause skin disorders like scalded skin syndrome and phaeohyphomycosis. Dermatomycoses are typically treated with topical or oral antifungal medications.
