Article Synopsis
  • The study investigates the genetic relationship between Mycobacterium tuberculosis (MTB) cultures and diagnostic samples from TB cases, challenging the idea that culturing leads to loss of genomic diversity.
  • Researchers developed an advanced workflow for sequencing sputum samples and performed a detailed bioinformatics analysis to examine discrepancies between sputum and culture results.
  • Findings show a high agreement of 97% in genetic variants between sputum and culture pairs, suggesting that culturing reflects the genomic makeup of MTB accurately across various TB epidemic settings.

The world health organization's global tuberculosis (TB) report for 2022 identifies TB, with an estimated 1.6 million, as a leading cause of death. The number of new cases has risen since 2020, particularly the number of new drug-resistant cases, estimated at 450,000 in 2021.

Antimicrobial peptides (AMPs) have emerged as promising candidates in combating antimicrobial resistance - a growing issue in healthcare. However, to develop AMPs into effective therapeutics, a thorough analysis and extensive investigations are essential. In this study, we employed an approach to design cationic AMPs , followed by their experimental testing.

In 2021, the World Health Organization recommended new extensively drug-resistant (XDR) and pre-XDR tuberculosis (TB) definitions. In a recent cohort of TB patients in Eastern Europe, we show that XDR TB as currently defined is associated with exceptionally poor treatment outcomes, considerably worse than for the former definition (31% vs. 54% treatment success).

Antiviral peptides (AVPs) are bioactive peptides that exhibit the inhibitory activity against viruses through a range of mechanisms. Virus entry inhibitory peptides (VEIPs) make up a specific class of AVPs that can prevent envelope viruses from entering cells. With the growing number of experimentally verified VEIPs, there is an opportunity to use machine learning to predict peptides that inhibit the virus entry.
