Corynebacterineae

Corynebacterineae is a suborder of bacteria that belongs to the order Actinomycetales. This suborder includes several important genera such as Corynebacterium, Mycobacterium, and Nocardia. These bacteria are Gram-positive and are known for their high GC content in their DNA.

Taxonomy

The suborder Corynebacterineae is divided into several families, including:

• Corynebacteriaceae
• Mycobacteriaceae
• Nocardiaceae
• Dietziaceae
• Gordoniaceae
• Tsukamurellaceae
• Williamsiaceae

Each of these families contains several genera and species, many of which are significant in human and animal health.

Characteristics

Members of the Corynebacterineae are generally Gram-positive, rod-shaped bacteria. They are known for their high GC content in their DNA, which can be as high as 65%. Many species are aerobic, but some can also grow under anaerobic conditions.

Medical significance

Several genera within the Corynebacterineae are of medical importance. For example, Corynebacterium diphtheriae is the causative agent of diphtheria, a serious respiratory illness. Mycobacterium tuberculosis causes tuberculosis, a major global health problem. Nocardia asteroides can cause nocardiosis, a rare but serious infection.
