non-tuberculosis mycobacteria (ntm), as certain species of mycobacteria, can affect human in several ways. in the preceding years, the rate of ntm detection has risen in both immunocompromised and immunocompetent patients. on the other hand, several reports have debated the possibility of co-infection of both mycobcateriu tuberculosis (mtb) and ntm in individuals that puts the role of ntm in di...
BACKGROUND Several nontuberculous mycobacteria (NTM) were previously isolated from diverse environments such as water, soil, sewage, food and animals. Some of these NTM are now known to be opportunistic pathogens of humans. OBJECTIVE The main purpose of the study was to identify NTM isolates stored at the National Microbiology Reference Laboratory (NMRL) and were previously isolated from huma...
BACKGROUND Non-Tuberculous Mycobacteria (NTM) are emerging around the world due to a higher prevalence of immunosuppressive illness and therapy. Saudi Arabia is not an exception as there have been novel mycobacterial species also identified. In addition, several published case reports from different parts of the country suggest a growing pathogenic potential of NTM. As the first nationwide stud...

The use of high-performance liquid chromatography (HPLC) revealed four previously unreported profiles within a group of mycobacteria consisting of 14 clinical isolates. These mycobacteria, whose identification by conventional tests appeared problematic, mostly resembled Mycobacterium avium complex or Mycobacterium simiae. Genetic analysis revealed, within this group, six different nucleic acid ...
Mycobacteria are an important cause of morbidity in humans. Rapid and accurate mycobacterial identification is important for improving patient outcomes. However, identification of Mycobacterium species is not easy, due to the slow and fastidious growth of mycobacteria. Recently, biochemical, sequencing, and probing methods have come to be used for identification. This study compared the perform...
'Mycobacterium sherrisii' is an undescribed species that appears to be emerging, in particular, among HIV-positive patients originating from Africa. To describe 'M. sherrisii', to ensure that the species name is validly published and to define its phylogenetic position, we collected 11 of these strains reported in five previous studies, and subjected them to biochemical identification, cell-wal...
