What is Candida parapsilosis? Candida parapsilosis has been classified under the emerging pathogens in the recent past, causing invasive candidal disease. It was first discovered in Puerto Rico by Ashford in 1928 from a diarrheal stool and later discovered to be a pathogenic agent in causing sepsis among intravenous drug users. It was initially named Monilia parapsilosis and later renamed to …
What is Chromoblastomycosis (Chromomycosis)? Chromoblastomycosis that is also known as chromomycosis is a chronic fungal infection of the skin and the subcutaneous tissue, caused by different groups of dematiaceous fungi. It is one of the most encountered subcutaneous fungal infections besides sporotrichosis and mycetoma. Dermateciuos fungi are fungi that are pigmented, producing brown pigmentations. The disease is associated with slow-growing, …
What is Sporothrix schenckii? Sporothrix schenckii is a dimorphic fungus that is widely distributed in soil and in and on living and dead decaying environments. It is a pathogenic fungus that causes an infection known as sporotrichosis, in both animals and humans. Sporotrichosis is a chronic mycotic infection that affects the cutaneous and subcutaneous tissues. The fungal infection is associated …
What is Candida tropicalis? Candida tropicalis is a yeast form of fungi known to be pathogenic in neutropenic hosts and disseminating through the bloodstream to peripheral organs. It is closely related to Candida albicans in pathogenicity and clinical features. It is a common systemic fungus, affecting persons with immune-compromised and immune-suppressed systems. The common treatment therapies for invasive infection of …
What is Candida glabrata? Candida glabrata was previously known as Torulopsis glabrata, belongs to the class of Fungi Imperfecti, the order of Moniliaes and family of Cryptococcaceae. C. glabrata is one of the most common candida species, living commensally in the human host. It does not cause disease in healthy individuals. However, it has been found to also cause candidiasis in persons …
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 of the skin, hair, and …
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 characteristics. The fungal spore cell …
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 severe in immune-compromised patients. The …
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 nails, beards, skin, and scalp. …
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 commonly known species including: A. …
