By sequencing the bacterial mRNA that bacteria break down (the degradome) during protein synthesis, a novel approach called 5PSeq was able to analyze how environmental exposure stress, including that of antibiotics, affected bacterial translational dynamics. This is what researchers from the Karolinska Institutet led by Vicent Pelechano have discovered in their study published on May 22, 2023, in Nature Microbiology.
Researchers at NYU Langone Health and Janssen Biotech Inc. have reported on mAbtyrins, bioengineered molecules composed of human monoclonal antibodies and centyrins that are a new way to fight Staphylococcus aureus infection on all fronts.In their experiments, which were published in Cell Host & Microbe on April 24, 2023, the team described mAbtyrin, as “a protein-based therapeutic that targets 10 disease-causing mechanisms employed by S. aureus,” senior author Victor Torres told BioWorld.
Another company has entered the fray in the eternal battle between humans and bacteria. Day Zero Diagnostics Inc. aims to produce whole genome sequencing-based diagnostic technologies that quickly identify the species and antibiotic resistance profile of bacterial pathogens from a blood sample. In a vote of confidence that the company is on the right track, the global non-profit Combating Antibiotic Resistant Bacteria Biopharmaceutical Accelerator (CARB-X) awarded Day Zero another $8.2 million. The latest funding pushes Day Zero’s awards from CARB-X over $16 million.
Scientists from the University of Queensland have created a new antibiotic that can neutralize various gram-positive bacteria in mice, including major threats such as methicillin-resistant Staphylococcus aureus (MRSA). In a recent study, published in the Sept. 14, 2022, issue of Science Translational Medicine, the new compound outperformed the approved antibiotic vancomycin, and destroyed tough-to-eradicate bacterial biofilms while prompting a low rate of resistance.

Antibiotics drugs discovery, Ursula Theuretzbacher told the audience at the 2022 European Congress of Clinical Microbiology & Infectious Diseases (ECCMID), has more than one challenge to overcome.
A team led by researchers from the ETH Zürich and the University of Basel has used a combination of mass spectrometry data and machine learning to predict antibiotic resistance of clinical bacterial samples. The results, which were published in the Jan. 10, 2022, issue of Nature Medicine, could speed the identification of optimal antibiotic regimens for patients.
Combining the metabolites glutamine or inosine with ampicillin (AMP) could represent a new therapeutic approach to antimicrobial resistance that also avoids the development of acquired resistance to next-generation antibiotics, according to a new Chinese study led by scientists at Sun Yat-sen University (SYSU) in Guangzhou.
Selux Diagnostics Inc. has received breakthrough device designation from the FDA for its Next Generation Phenotyping (NGP) platform for positive blood culture and sterile body fluid samples. The NGP technology is a diagnostic platform designed to help with the delivery of personalized antimicrobial therapies within 24 hours. The Boston-based company is hoping the technology can tackle the global antibiotic resistance crisis. According to the World Health Organization, antimicrobial resistance is one of the top 10 global public health threats facing humanity.
A multicenter study has found that a multiplex diagnostic panel developed by Opgen Inc. can reduce the use of inappropriate antibiotic therapy by 45.1%. Opgen’s Unyvero Hospitalized Pneumonia (HPN) panel uses PCR technology that can detect 21 pathogens and 17 antibiotic resistance markers in less than five hours. During the European Respiratory Society conference, Rockville, Md.-based Opgen presented data showing that combined with antibiotic stewardship, its HPN panel decreased time on inappropriate antibiotic therapy in hospitalized patients with pneumonia at risk for Gram-negative rods.
