Mycobacterium orygis is a species of the tuberculosis complex of the genus Mycobacterium. It causes tuberculosis in Oryx, Rhinos, dairy cattle, rhesus monkeys, and humans.
Morphology[edit]
Mycobacterium orygis is similar in morphology to species in the tuberculosis complex of Mycobacterium. It is a non-motile, acid fast bacteria. The cell walls are composed primarily of Mycolic acids. The cells are irregular rods, 0.3-0.5 um in diameter and 2-3 um in length.[1]
Metabolism[edit]
Mycobacterium orygis is an obligate aerobe, and a facultative intracellular pathogen. It has a doubling time of 15-20 hours within cells, and longer when outside cells. Mycobacterium orygis uses the host's cells internal fatty acids for both a carbon source and an energy source. These molecules include cholesterol, triacylglycerides, and glycosphingolipids. The optimum growing range for this sepcies is 32 degrees celcius.
Genome[edit]
Strain 51145, obtained from a human diagnosed with tuberculosis meningitis in 1997, has a 4.4 Mbp genome, 4032 genes and a GC content of 65.6%.
