What are the mycetoma agents?

What are the mycetoma agents?

The etiologic agents of mycetoma are aerobic and anaerobic bacteria (actinomycetoma) and fungi (eumycetoma). In the tissue, these organisms are found in compact aggregates of filamentous bacterial colonies or fungal hyphae, which will characterize the grains.

What disease does mycetoma cause?

Mycetoma is a chronic, granulomatous disease of the skin and subcutaneous tissue, which sometimes involves muscle, bone, and neighboring organs. It is characterized by tumefaction, abscess formation, and fistulae. It typically affects the lower extremities, but it can occur in almost any region of the body.

What is mycetoma disease also called as?

Diagnostic method. Ultrasound, fine needle aspiration. Mycetoma is a chronic infection in the skin caused by either bacteria (actinomycetoma) or fungi (eumycetoma), typically resulting in a triad of painless firm skin lumps, the formation of weeping sinuses, and a discharge that contains grains.

Which of the following is the causative agent of Black grain mycetoma?

Abstract. A new species of nonsporulating fungus, isolated in a case of black-grain mycetoma in Sudan, is described as Madurella fahalii.

What is the causative agent of sporotrichosis?

Sporotrichosis (also known as “rose gardener’s disease”) is an infection caused by a fungus called Sporothrix. This fungus lives throughout the world in soil and on plant matter such as sphagnum moss, rose bushes, and hay. People get sporotrichosis by coming in contact with the fungal spores in the environment.

What is the causative agent of histoplasmosis?

Histoplasmosis is an infection caused by a fungus called Histoplasma. The fungus lives in the environment, particularly in soil that contains large amounts of bird or bat droppings.

What kind of infection is mycosis?

A fungal infection, also called mycosis, is a skin disease caused by a fungus. There are millions of species of fungi. They live in the dirt, on plants, on household surfaces, and on your skin. Sometimes, they can lead to skin problems like rashes or bumps.

Why is it called Madura foot?

The first modern description of Madura foot was made in 1842 from Madurai (the city after which the disease was named Madura-mycosis) in India, by Gill. The fungal cause of the disease was established in 1860 by Carter.

What is the causative agent of blastomycosis?

Blastomycosis is an infection caused by a fungus called Blastomyces. The fungus lives in the environment, particularly in moist soil and in decomposing matter such as wood and leaves.

What causes dermatophytes?

Dermatophytes are fungi that require keratin for growth. These fungi can cause superficial infections of the skin, hair, and nails. Dermatophytes are spread by direct contact from other people (anthropophilic organisms), animals (zoophilic organisms), and soil (geophilic organisms), as well as indirectly from fomites.

What causes mycetoma under skin?

The resulting infection causes firm, usually painless but debilitating masses under the skin that can eventually affect the underlying bone. Mycetoma can be caused by bacteria (actinomycetoma) or fungi (eumycetoma).

What is mycetoma of the foot?

Mycetoma is a chronic disease usually of the foot but any part of the body can be affected. Infection is most probably acquired by traumatic inoculation of certain fungi or ‎bacteria into the subcutaneous tissue. The disease commonly affects young adults, mostly males aged between 15 and 30 years in developing countries.

What are the different types of mycetoma?

Fungal mycetoma (also known as eumycetoma) is the most common type in Africa. Bacterial mycetoma (sometimes referred to as actinomycetoma) causes most cases in South and Central America and some Asian countries.

What is eumycetoma and what causes it?

Mycetoma is categorized according to etiology: Those caused by filamentous aerobic Actinomyces, such as Nocardia, Actinomadura, and Streptomyces, are referred to as actinomycetoma. Those caused by true fungi that named eumycetoma.
