MEDEROS CUERVO, LM et al. Diagnostic importance of genitourinary infections caused by the genus Mycobacterium from symptomatic patients and living with HIV/AIDS. Rev. CENIC Cienc. Biol [online]. 2021, vol.52, n.2, pp.146-152.  Epub 01-Ago-2021. ISSN 2221-2450.

Genitourinary infections caused by the genus Mycobacterium have a slow evolution, generally due to their late diagnosis. In this study, urine samples from symptomatic patients were analyzed microbiologically looking for the presence of acid-alcohol resistant bacilli. the samples were analyzed according to diagnostic techniques established in the Microbiology Laboratories. A total of 257 urine samples received during the period December 2017-December 2019 were analyzed at the National Reference and Research Laboratory of Tuberculosis / Mycobacteria / Leprosy of the Institute of Tropical Medicine "Pedro Kourí" (IPK), of these 194 (75.48 %) from HIV / AIDS patients. The results obtained were; 30 (11.67%) Mycobacterium tuberculosis (MTB) isolates and 35 (13.61%) of non-tuberculous mycobacteria (NTM). Analyzing the results obtained, we can see that within the non-tuberculous species with the highest percentage of isolation, those belonging to groups III and IV are maintained according to the classification described by Runyon, the non-tuberculous species with the highest percentage of isolation are those belonging to the Mycobacterium avium-intracellulare complex and Mycobacterium fortuitum complex. This study confirmed the importance of the early clinical-microbiological diagnosis in this type of infection, since it will allow the start of specific treatment, especially in patients with some type of deterioration in their immune barrier, to avoid the risk of infectious spread.
