Article Abstract
Nontuberculosis mycobacteria (NTM) are opportunistic pathogens that cause a wide range of illnesses. Here, the species distribution and prevalence of NTM infections in tuberculosis suspects was analyzed. A total of 7,073 specimens from pulmonary and extrapulmonary sites were analyzed, and 709 (10%) were found to be culture positive for mycobacteria. Of these, 85.2% were identified as Mycobacterium tuberculosis complex and 14.8% as NTM (65.7% rapid growers and 34.3% slow growers). Speciation of the NTM isolates (n = 69) identified 19 NTM species. M. abscessus (33.3%) and M. fortuitum (24.6%) were the most dominant NTM species isolated from the patients, followed by M. porcinum (5.8%) and M. parascrofulaceum (4.3%). We also report peritonitis caused by rapidly growing NTM among the patients undergoing continuous ambulatory peritoneal dialysis and a case of M. senegalense peritonitis. A low prevalence but high species diversity of NTM was detected in our study. The high species diversity of NTM necessitates the need to unequivocally identify mycobacterial isolates for appropriate treatment.

Infectious complications in peritoneal dialysis (PD) remain a constant challenge, with atypical pathogens posing significant risks. This case from Thailand highlights the rare occurrence of , an often-overlooked non-tuberculous mycobacterium (NTM), as the causative agent in a catheter-related exit-site infection that progressed to peritonitis. Initially misattributed to from preceding exit-site infections, was ultimately identified as the primary pathogen through multiple effluent cultures and advance polymerase chain reaction sequencing.

Background: Recurrent Non-Tuberculous Mycobacterial Pulmonary Disease (NTM-PD) related to treatment with Secukinumab has not been previously documented.
Case Presentation: Despite adherence to treatment and avoiding hot springs, a plaque psoriasis patient experienced persistent NTM-PD relapses.
Conclusions: There is potential association between Secukinumab, an IL-17A inhibitor, and NTM disease, echoing anti-TNF biologics' NTM risk, indicating the urgent need for further research on pathogenic mechanisms and risk factors.
