Microsporum spp are dermatophyte fungi that cause cutaneous infections of the nails, hair, and skin, known as dermatophytosis. They are ascomycetous molds producing macroconidial spores which are distinct for these group of dermatophyte, distinguishing them from other dermatophytes such as Trichophyton and Epidermophyton. Microsporum spp are keratolytic i.e they synthesis keratinase enzyme which digests fragments … Read more Microsporum spp
Lactophenol Cotton Blue (LPCB) Staining is a simple histological staining method used for the microscopic examination and identification of fungi. Principle of Lactophenol Cotton Blue (LPCB) Staining Lactophenol Cotton Blue (LPCB) Staining method works on the principle of aiding the identification of the fungal cell walls. Fungi are eukaryotic organisms with both macroscopic and microscopic … Read more Lactophenol Cotton Blue (LPCB) Staining
What is Aspergillus clavatus? Aspergillus clavatus is a pathogenic species of fungi, that produces mycotoxins that cause severe pulmonary disease, an allergic reaction commonly known as malt’s worker’s lung. They produce millions of very tiny spores known as conidia, that circulate freely in the air and when inhaled. they cause allergic reactions which may be … Read more Aspergillus clavatus
Trichophyton is a dermatophyte fungus classified along with Epidermophyton and Microsporum spp. Dermatophytic fungi are known to cause of dermatophytosis, a cutaneous infection of the skin, hair, and nails, in humans and animals. Trichophyton spp specifically causes tinea infections such as tines pedis (Athletes foot), tinea capitis (ringworms), tinea crusi (jock itch), and infections of the … Read more Trichophyton spp
Alternaria spp Alternaria spp are a group of Ascomycete fungi that are known for their saprophytic nature in decomposing soil and plants. They are ubiquitous, found in soil, air, and plants. They have a clinical impact as well as, it is a plant pathogen. There are over 299 species of Alternaria spp with the most … Read more Alternaria alternata
Rhizopus spp are saprophytic fungi found on plants and it is parasitic on animals. They are multicellular fungi, with about 8 species. They are responsible for causing an opportunistic infection known as invasive mucormycosis in humans and animals. Some species are used for industrial importance such as Rhizopus stolonifer which caused bread mold. Rhizopus infections … Read more Rhizopus spp
Epidermophyton floccosum is a filamentous dermatophytic fungus known to cause skin and nail infections in humans. It is an anthropophilic dermatophyte hence it is transmissible from one individual to another. Common infections caused by dermatophytes include tinea pedis (athlete’s foot), tinea crusis, tinea corporis, and onychomycosis. It is the third most common cause of Tinea … Read more Epidermophyton floccosum
Blastomyces dermatitidis is a thermally dimorphic fungus that causes blastomycosis, a chronically invasive fungal infection of the lungs, that disseminates into the skin and bones and it affects both humans and animals. The disease is predominantly endemic in North America (the United States and Canada) hence it has been coined as North America Blastomycosis. It … Read more Blastomyces dermatitidis
Coccidioidomycosis is a systemic infection caused by inhalation of Coccidioides immitis or Coccidioides posadasii spores. It affects both humans and animals. It is also known as Valley fever or cocci or California fever, or desert rheumatism, or San Joaquin Valley fever. The spores of the causative agents are commonly found in soil in endemic areas, where they … Read more Coccidioidomycosis
Fusarium is a large group of filamentous fungi belonging to the hyphomycetes. Commonly distributed widely in the soil they are saprophytic fungi known to associate with plants, causing a wide range of plant diseases. This is because of their ability to produce mycotoxins especially in cereal crops, which can cause disease in human and animal … Read more Fusarium spp
Candidiasis definition Candidiasis is also known as moniliasis, is a fungal disease that is classified under opportunistic fungal infection, because of its occurrence in persons with an immune-suppressed system, especially newborns, HIV/AIDS patients, patients on antibiotic therapies, cancer therapy patients. It usually does not cause disease in healthy individuals. It is an overgrowth in the … Read more Candidiasis and types of Candidiasis
Figure: Penicillium chrysogenum. Image Source: Pinterest, created using biorender.com Penicillium chrysogenum is also known as Penicillium notatum, the first Penicillium fungi used for the isolation of penicillin antibiotics, which is used for the treatment of Gram-positive bacteria. It is also used in the production of other β-lactam antibiotics. It is an allergen and has pathogenic … Read more Penicillium chrysogenum
