Fungal
Fungi are a diverse group of organisms that include yeasts, molds, and mushrooms. From a medical perspective, these microorganisms are significant because they can cause a wide range of infections in humans, known as mycoses. These infections may range from superficial, affecting the skin, nails, or hair, to systemic, affecting internal organs or the bloodstream. Superficial fungal infections are relatively common and include conditions like athlete's foot, ringworm, and yeast infections. More serious systemic infections, like histoplasmosis or cryptococcal meningitis, can occur, particularly in individuals with weakened immune systems, including those with HIV/AIDS or who are taking immunosuppressive medications.
Fungi reproduce by releasing spores that can be inhaled or come into contact with the skin, leading to infection. Diagnosis of fungal infections often involves microscopic examination, culture of specimens, or serological tests to identify fungal antigens or antibodies in the blood. Treatment varies depending on the type and severity of the infection, with antifungal medications being the mainstay of therapy. These medications can be topical, oral, or intravenous. Antifungal resistance, similar to antibiotic resistance in bacteria, is an emerging concern, urging the medical community to continuously research and develop new treatment strategies.
