Tuberculosis (TB) is a chronic infection disease caused by Mycobacterium tuberculosis (MTB), as an intracellular pathogen. Various cytokines (TNF-alpha, IL's,GSF etc.) and other factors play important preventing roles and are secreted during the infection. It may cause changes in the metabolism of neutrophils. Production of superoxide anion and antioxidative enzymes activities, such as glutathione reductase (GSSGR) and catalase (CAT) may be changed during MTB infection in the host.
