Objective: Tuberculosis (TB) is a bacterial, infectious disease caused by Mycobacterium Tuberculosis complex. TB causes a wide range of clinical infections affecting many parts of the body. Multi-drug resistant tuberculosis (MDR-TB) is caused by bacteria that are resistant to both isoniazid and rifampicin, the most effective anti- TB drugs, or more. MDR-TB presents a major concern in many countries and continues to threaten TB control. Methods: A retrospective cohort study carried out from 5 Jan 2020 to 30 March 2020 at the Specialized Chest and Respiratory Disease Center in Baghdad. The records of the patients who received multidrug treatment were included in the study. On the other hand, all the records that not contain full information about the socio-demographic characteristics, history of travelling or other disease, type and duration of treatment, and drug culture sensitivity excluded from the study. Results: From the 650 patients whom there records were reviewed, 130 patients had single or multi-drug resistance mainly to rifampicin and isoniazide. Comparing the presence of drug resistance according the gender showed that the number of males who had resistance to drugs was higher than that of females. Conclusion: Tuberculosis affects mainly the productive age group. It affects males more than females. Resistance to anti TB drugs was found in one fifth of patients who received treatment.
