SPECIFIC FUNCTIONS OF LICHEN ACIDS (SECONDARY METABOLITES)

Lichens produce two types of metabolites: primary metabolites (e.g. carbohydrates and amino acids) and secondary metabolites (e.g. alkaloids and lichen acids). Primary metabolites (which are intracellularly secreted) are critical to the survival of the lichens while secondary metabolites are rarely involved in the metabolism or growth of the lichenized fungi. Secondary metabolites of lichens are […]

LICHEN METABOLISM

DrChika

All microorganisms carry out two modes of metabolism during their lifetime, and these are mainly primary metabolism and secondary metabolism. Primary metabolism is very indispensable to the survival of all microbial cells as it is during this metabolic activity that important compounds (known as primary metabolites) such as nucleic acids, amino acids, vitamins and enzymes

LICHENS AND THEIR BIOLOGICAL SIGNIFICANCE

DrChika

Lichen is simply a symbiotic association of slow-growing microorganisms that is composed mainly of a fungus and cyanobacteria or green algae. They are a composition of twin or double organisms, and are very rich in chemical compounds as expressed by the varying colours that they produce on the surfaces where they form. Lichens grow on

TREATMENT & PREVENTION OF FUNGAL INFECTIONS

DrChika

Fungal infection is treated using antifungal drugs. Some of the drugs used for the treatment of mycoses in humans include: PREVENTION AND CONTROL OF FUNGAL INFECTIONS The prevention and control of mycoses is largely dependent on avoiding exposure to fungal spores or conidia and limiting contact with natural reservoirs of most fungal organisms. An intact

MYCOTOXINS

DrChika

Mycotoxins are exotoxins produced by fungi. The area of microbiology that studies fungi and the toxins they produce (i.e. mycotoxins) is known as mycotoxicology. The disease condition provoked by the intake of mycotoxins in human or animal hosts is generally known as mycotoxicoses. Mycotoxins are pharmacologically active secondary metabolites produced by toxin-producing fungi in food,

ORAL THRUSH (ORAL CANDIDIASIS)

DrChika

Oral thrush (oral candidiasis) is a localized fungal infection caused by C. albicans in the oral cavity of humans such as the tongue, lips and gums. Oral thrush is a fungal infection of the mouth; and thrush or oral thrush is an infection of the mouth caused by the Candida fungus which is a yeast

SUPERFICIAL MYCOSES

DrChika

Superficial mycoses are fungal infections which are only limited to the keratinized outer layer of the skin, hair and nails. Superficial mycoses unlike other forms of mycoses rarely result in inflammatory reactions in the host but it is usually characterized by intense itching and peeling or scaling of the affected body sites. They are self-limiting

MYCOSES – fungal infections

DrChika

Mycoses are infections caused by pathogenic fungi. And they include superficial mycoses, cutaneous mycoses, subcutaneous mycoses, systemic or deep-seated mycosis and opportunistic mycoses depending on the affected tissue or parts of the body. However, other forms of fungal infections which are not directly caused by pathogenic fungi but their toxic products and the untoward reactions

STRUCTURES OF FUNGI

DrChika

The spores (conidia) are produced in dry chains from the tips of the phialides, with the youngest spore at the base of the chain (Figure 1). Penicillium is found in the soil, decaying vegetation, air and they are common contaminants on various substances. Penicillium causes food spoilage, and it colonizes leather objects. It is an

Candida glabrata

DrChika

Biology of Candida glabrata Candida glabrata is a fungus species of haploid yeast of the genus Candida, previously known as Torulopsis glabrata. Despite the fact that no sexual life cycle has been documented for this species, C. glabrata strains of both mating types are commonly found. Vaginal yeast infection, caused mainly by Candida albicans (and
