NewsNovel antibiotic BTZ-043 also reaches tuberculosis bacteria hiding in dead lung tissue
Researchers have shown that the novel antibiotic BTZ-043 effectively penetrates tubercolous lesions and accumulates there in high concentrations. Consequently, the drug can fight Mtb bacteria even in hard-to-reach areas.

NewsEvolutionary tradeoffs: Research explores the role of iron levels in COVID-19 infections
Iron has been found to be essential to both human physiology and pathogen replication. The richer the iron availability, the more likely to be susceptible to infections, such as COVID-19. A balance of iron levels is thus critical for homeostasis and preventing pathogenic infections.
