A species of bacterium of the family NOCARDIACEAE, producing pulmonary infections in man.

Infections with bacteria of the genus NOCARDIA.

A genus of gram-positive, aerobic bacteria whose species are widely distributed and are abundant in soil. Some strains are pathogenic opportunists for humans and animals.

Bacterial variants, unable to form a complete cell wall, which are formed in cultures by various bacteria; granules (L bodies) appear, unite, and grow into amorphous bodies which multiply and give rise to bacterial cells morphologically indistinguishable from the parent strain.

Mycolic acids are complex, long-chain fatty acids that are a major component of the cell wall of Mycobacterium species, including the causative agents of tuberculosis and leprosy, providing them with unique characteristics such as resistance to acid-alkali stability, pigmentation, and protection against host immune responses.

An anti-infective agent that is used topically to treat skin infections and orally for urinary tract infections.

Bacterial infections of the brain, spinal cord, and meninges, including infections involving the perimeningeal spaces.

The dry cells of any suitable strain of SACCHAROMYCES CEREVISIAE or CANDIDA. It can be obtained as a by-product from the brewing of beer or by growing on media not suitable for beer production. Dried yeast serves as a source of protein and VITAMIN B COMPLEX.

Accumulation of purulent material in tissues, organs, or circumscribed spaces, usually associated with signs of infection.
