Special Issue Information
Dear Colleagues,
Tuberculosis (TB) remains a significant global public health challenge, particularly in resource-limited regions. It consistently ranks among the top ten causes of mortality worldwide and is currently the leading cause of death from a single infectious agent, surpassing previous years’ statistics, even during the Covid-19 pandemic. Furthermore, over 100 countries are severely affected by TB and HIV co-infection. In recent decades, there has been a documented increase in the global prevalence and incidence of non-tuberculous mycobacterial (NTM) infections. The prevalence of NTM in adults with non-cystic fibrosis bronchiectasis from 2006 to 2021 is estimated to be approximately 10%, with significant geographical variations.
Combating TB requires a comprehensive strategy that extends beyond traditional control measures. The World Health Organization’s End TB Strategy emphasizes research and development, innovative diagnostics, and effective treatments. Although two new molecules for TB treatment were recently introduced, their adoption has been limited due to high costs. Therapeutic approaches for NTM infections face significant challenges, including drug resistance, lengthy treatment durations requiring strict patient adherence, and the risk of adverse drug reactions. Effective management necessitates continuous monitoring, potential surgical interventions, and comprehensive non-pharmacological support, underscoring the need for a multidisciplinary approach.
Recent research indicates substantial delays in TB diagnosis. Obtaining a mycobacterial culture, the gold standard for diagnosis, can take up to eight weeks, which is impractical for high-burden countries due to the need for advanced laboratory infrastructure. The detection of acid-fast bacilli (AFB), a diagnostic test for pulmonary TB, has limited accuracy. Automated PCR assays offer a faster alternative but are costly and require specialist personnel and equipment. Diagnostic approaches for NTM infections also face several challenges, including non-specific clinical presentations, difficulties in distinguishing true infections from environmental contamination, and limitations in culturing and advanced molecular diagnostics. These issues necessitate comprehensive diagnostic workups, repeated testing, and specialist consultation, highlighting the need for improved diagnostic tools and protocols. Therefore, there is a pressing need to develop new diagnostic tools in microbiology, genetics, immunology, omics, and biomedicine. These tools should facilitate the rapid and precise diagnosis of antimycobacterial diseases, considering comorbidities and autoimmune conditions. Our goal is to improve diagnostic pathways and support timely and effective treatment interventions.
This Special Issue invites contributions that explore biomarkers, diagnostic innovations, and therapeutic approaches for mycobacterial diseases. We seek research articles, reviews, and case studies that present new insights and advancements in these areas.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Tropical Medicine and Infectious Disease is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs).
