The main aetiologic agent of Cutaneous tuberculosis is Mycobacterium tuberculosis (Mtb) that belongs to the class Schizomycetes, order Actinomycetales
, family Mycobacteriaceae and genus Mycobacterium.
Actinobacteria consisted primarily of the Class Actinobacteria (>70% within this phylum; data not shown) and the Order Actinomycetales
(>99% within the Class Actinobacteria; data not shown).
Streptomyces, gram -positive bacteria in the order Actinomycetales
are able to produce extracellular secretions with different properties such as antibacterial, antifungal, antiviral, nematicidal, antitumor, and enzyme inhibitory activities (7,8).
The bacteria belong to the order Actinomycetales
, family Nocardiacea and the main species that affect domestic animals are N.
Dermatophilosis (also known as streptothrichosis, or in sheep as 'lumpy wool disease') is caused by bacterium Dermatophilus congolensis, the type species of genus Dermatophilus, which is a member of the order Actinomycetales
(Stewart, 1972 and Msami et al., 2001).
Kocuria rosea belongs to genus Kocuria (Micrococcaceae family, suborder Micrococcineae, order Actinomycetales
) that includes about 11 species of bacteria, characteristically gram positive and aerobic (although some species like Kocuria kristinae, Kocuria marina and Kocuria rhizophila may proliferate in anaerobic conditions).
The two groups are the eumyces, or true fungi, and the actinomyces, filamentous bacteria of the order Actinomycetales
The order Actinomycetales
includes the families Mycobacteriaceae and Nocardiaceae, among others.
Several clinically significant antibiotics as well as widely used drugs against common diseases have been derived from this unique genus affiliated with the order Actinomycetales
