Abstract:
Tuberculosis (TB) remains a major public health problem worldwide due to its high risk of person-to-person transmission, morbidity and mortality [1]. Sudan has a high burden of tuberculosis. Spoligotyping (spacer oligonucleotide typing) a rapid method for genotyping of Mycobacterium tuberculosis using the principle of reverse hybridization. The ecology of the prevalent mycobacteria strain can vary depending on country and region. The aim of this study was to determine the genotyping of Mycobacterium tuberculosis isolated from Sudan using spoligotyping SPOLDB4. A total of 75 Mycobacterium tuberculosis sputum samples were collected from pulmonary Tuberculosis patients attending references Laboratories and diagnostic centers in Khartoum and Eastern Sudan in (2011-2013). The mycobacteria were genotyped using Spoligotyping technique and data obtained were analyzed and compared to the SPOLDB4 database. Among the 75 isolate analyzed, 57(76%) were identified by SPOLDB4 and 18 (24%) could not be matched to any lineages. The most prevalent genotype cluster was MANU2 38 (50.7%) followed by CASI Delhi 8 (10.7%). In the study SIT54 was the most common pattern 37 (49.3%) followed by SIT25 6(8%).

Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
