Weighing balances are used to measure the weight of objects (particularly powdered agar and reagents) in the microbiology laboratory. Several weighing balances exist for measuring media and other substances in the microbiology laboratory and they include mechanical weighing balance and chemical or analytical weighing balances amongst others. They provide accurate readings or values of material […]
Thermocycler or thermal cycler is a piece of equipment is used for the copying or amplification of specific sequences of nucleotides through a controlled timing and temperature regulation. It is an important tool in the molecular biology laboratory. Thermocycler allows reaction mixtures in specialized tubes known as Eppendorf tubes (PCR tubes) to be heated and

Systemic mycoses are fungal infections that affect deep tissues and organs of the body; and they generally start off as pulmonary infections in affected individuals. They are the most disseminating, deadly and severe forms of mycoses out of all the known fungal mycoses in humans. Systemic mycoses generally involve the internal body organs of humans
Subcutaneous mycoses are fungal infections that affect the subcutaneous tissues below the skin, and the bone and other tissues occasionally. The subcutaneous tissue or layer is the part of the skin that lies beneath the skin and it contain large deposits of fats (e.g. in the buttocks and thigh regions). Apart from affecting the subcutaneous

Cutaneous mycoses are fungal infections of the skin, nails and hairs; and they are mainly caused by dermatophytes. While superficial mycoses involves the outermost layers of the skin; cutaneous mycoses generally affects the epidermis layer of the skin i.e. the layer of the skin that underlies the outer skin surface. Cutaneous mycoses can also be
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 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

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

There are various forms of halitosis (bad breath) that an individual can experience at different points in their life time. While some forms of bad breath may be caused by the type of food the individual consumed or ate; other forms of halitosis may warrant clinical investigation in order to remedy the situation. Morning breath

Microbiology of Oral Infection
Bad breath is clinically known as halitosis. Halitosis is an oral health condition that affects the oral hygiene of humans, and it is mostly experienced as mouth odour i.e. the release of foul smell from the buccal cavity (mouth). The phrase “halitosis” is derived from the Latin word “halitus” which means breath and the Greek
