Nearly 100 mycobacterium belong to rapidly growing mycobacterium (RGM), the most common pathogens being M. chelonae M. abscessus groups and M. fortitum complex, M. abscessus is more resistant to antibiotic and disinfection. Nontuberculosis mycobacteria have been isolated from various sites viz., cutaneous and soft tissue infection, after skin injury following inoculation and after surgical procedures and also, known to cause systemic infection in AIDS and immunocompromised patients. Surgical site infection due to atypical mycobacterium usually has a long incubation period.
Material and Method
Swaps from infected wound surgical were collected randomly from 40 patients, the bacterial DNA were extracted from the samples by using the CTAB method. The different primer designed to detect M. abscessus, M. chelonae, and M. fortitum complex. Were used DNA amplification was performed under different optimization PCR condition for different nontuberculosis mycobacteria species. The PCR products were separated by electrophoresis using 2% agarose and the products were visualized in gel documentation system. A 100pb ladder was used for comparison of product length.
The prevalence of NTM infection among patients with post-operative wounds was 17.5% for M. abscessus, 15% for M. fortitum and 0% for M. chelonae. Infection was higher in males (17.5%) in comparison to females (7.5%). NTM organism were detected in all delayed healing periods from 7 days to two years.


Our result shows that the M. abscessus and M. fortitum infection were found among patient with post operative wounds in Sudan. The infection are higher in males than females. Further investigation is needed to identify strains of NTM found in hospitals for proper control it and to study whether this microorganism can cause (nosocomial infection).
