When a drug prevents bacteria from synthesizing their own folate, an essential compound for their survival, they take it directly from the host. This antibiotic resistance mechanism had not been detected until now because bacteria behave differently in the laboratory than they do in vivo during an infection.

Researchers from the University of Queensland have published preclinical data on the novel glycopeptide antibiotic MCC-5145, being developed for the treatment of gram-positive bacterial infections.
Forge Therapeutics Inc. has synthesized new UDP-3-O-(R-3-hydroxymyristoyl)-N-acetylglucosamine deacetylase (LpxC) (bacterial) inhibitors reported to be useful for the treatment of Gram-negative bacterial infections.
Executives of Spero Therapeutics Inc. evaded analysts’ attempts to clarify “deficiencies” noted by the U.S. FDA in its ongoing review of the company’s NDA seeking approval of oral carbapenem antibiotic tebipenem HBr for complicated urinary tract infections (cUTIs), emphasizing instead that they have three months to work with the regulator ahead of a June 27 PDUFA date assigned to the application.
Researchers at the Peter Doherty Institute for Infection and Immunity, the University of Queensland, Griffith University, the University of Adelaide and St. Jude Children's Research Hospital have unlocked a key to making existing front-line antibiotics work again against Streptococcuspneumoniae, the bacteria that cause pneumonia.
An international study led by scientists at the University of Exeter in the U.K. suggests how to combine antibiotic and bacteriophage therapy optimally, in order to reduce antibiotic use and potentially prevent multidrug resistance in bacteria.
Even as antimicrobial resistance is expected to continue to grow, the development of much-needed novel antibiotics and antifungals remains trapped in a catch-22 in which funding is available for early stage research but not necessarily for the translational work necessary to bring the drugs to market.
Attaching a modified bacterial-derived formyl peptide chemoattractant to an antibiotic enhanced recruitment of neutrophils and improved their bactericidal ability in mouse models, according to a study led by European Molecular Biology Laboratory Australia researchers at Monash University in Melbourne.
Top-line results of a phase III trial testing sulbactam-durlobactam, a combination beta-lactam antibiotic and beta-lactamase inhibitor, in patients with carbapenem-resistant Acinetobacter baumannii infections, found the novel combo to be statistically noninferior to colistin in 28-day all-cause mortality, the study's primary endpoint.
