Special Issue Information

Dear Colleagues,

Antibiotics targeting Mycobacterium tuberculosis have been around for more than 75 years now. However, treatment of tuberculosis is extremely challenging and mandates the use of multiple drugs in a strict regimen to effect a successful cure.

The main requisites for a candidate new drug against TB are

  • Good cidal activity to be able to rapidly reduce the bacterial population and thereby minimize further transmission;
  • (Better?) activity against the bacteria during the persistent phase to ensure quick and complete cure;
  • Low frequency of drug resistance.

While there have been several promising new compounds that have been added to the pipeline in the last few decades, we still do not have any compound that specifically targets the persistent phase of M. tuberculosis infection. Targeting persistent subpopulations is extremely crucial if we are to achieve the goal of shortening the duration of TB therapy. Recent advances in single-cell biology and imaging have helped us to gain an understanding of some of the challenges to achieving these goals. This Special Issue seeks manuscript submissions that expand our understanding of the mechanisms M. tuberculosis adopts to survive and persist against antibiotics. Submissions on approaches to identify compounds that can specifically target these persisting subpopulations are especially encouraged.

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. Antibiotics 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 2900 CHF (Swiss Francs).

Mycobacterium tuberculosis infection continues to be a major global challenge. All patients with pulmonary tuberculosis are treated with a standard 6-month treatment regimen. Historical data suggest that even with shortened treatment, most patients achieve long-term remission. Risk stratification is a goal for reducing potentially toxic prolonged treatment. This study aimed to determine the factors associated with the early clearance of sputum acid-fast bacilli (AFB). A total of 297 freshly diagnosed patients with pulmonary tuberculosis were included and enrolled in this study. Information related to their ethno-demographic and anthropometric characteristics was collected. We also assessed their complete blood counts, and blood iron, folate, and vitamin B12 levels. We found that the presence of higher levels of acid-fast bacilli (AFB) in diagnostic sputum microscopy was the single most significant prognostic factor associated with early clearance of sputum AFB after 2 months of treatment. All of our patients achieved treatment success after 6 months of treatment and were disease free. Our results support the data obtained from previous studies indicating that AFB clearance at 2 months is unlikely to be a clinically useful biomarker or indicator for therapeutic stratification. Furthermore, demographic, anthropometric, and nutritional factors are not clinically useful biomarkers. Full article
