(Greek: mucus; a protective secretion from the mucous membranes in the nose, throat, and lungs; a thick fluid produced by the linings of some tissues of the body and is secreted as a protective lubricant coating by cells and glands of the mucous membranes)

Don't confuse this myco- meaning "mucus" with another myco- meaning "fungus, fungi".

actinomyces (s) (noun), actinomyces (pl)
One of several saprophytic, filamentous, anaerobic bacteria of the genus Actinomyces, certain species of which are pathogenic for humans and animals: Actinomyces are known for causing diseases in humans and for the important role they play in soil ecology.

Actinomyces produce a number of enzymes that help degrade organic plant material, lignin and chitin. As such, their presence is important in the formation of compost.

actinomycosis (s) (noun), actinomycoses (pl)
An inflammatory bacterial disease of cattle and other animals, sometimes caught by humans, that resembles a fungus and causes swelling of the abdomen, chest, and especially the jaw: Actinomycosis, a chronic disease of cattle, swine, and humans, is characterized by hard granulomatous masses, usually in the mouth and jaw.

It is also distinguished by deep, lumpy abscesses that extrude a yellow, granular pus through multiple sinuses.

This disease occurs worldwide, but is seen most frequently in those who live in rural areas.

Pertaining to, or characteristic of, fungi of the class Basidiomycetes; a fungus that produces its spores in a characteristic club-shaped cell basidium.

Mushrooms, puffballs, rusts, bracket fungi, and smuts are basidiomycotes.

1. A fungal infection causing lesions on the lungs, skin, or mucous membranes.
2. Infection with a fungus called Blastomyces dermatitidis.

It usually presents a flu-like illness with fever, chills, productive cough, myalgia, arthralgia, and pleuritic chest pain.

Some patients fail to recover and develop chronic pulmonary infection or widespread disseminated infection; affecting the skin, bones, and genitourinary tract. It occasionally affects the meninges which cover the brain and spinal cord.

People who are at an elevated risk for the disease are those in areas with endemic disease with exposures to wooded sites; such as, farmers, forestry workers, hunters, and campers. The disease can leave permanent lung damage.

1. A fungal infection characterized by itchy warty nodules (bumps) on the skin.
2. A long-term fungal infection of the skin and subcutaneous tissue.
Fungus dust.
1. A superficial infection of the skin or its appendages by fungi.
2. A fungal infection of the skin; especially, of moist parts of the body that are covered by clothing.
One of the great divisions of fungi, containing species which have naked spores carried on free or only fasciculate (small bundles or clusters) of threads.
