Marginal Zone B Cells Unveiled as Key Players in TB Vaccine Strategy

An "unconventional" immune response now identified by scientists from the Hackensack Meridian Center for Discovery and Innovation (CDI) is a potential new pathway for developing new vaccines for tuberculosis (TB), according to a new publication.

Researchers Uncover Bacterial Alarm Mechanism Against Antibiotics

When confronted with an antibiotic, toxic substance, or other source of considerable stress, bacteria are able to activate a defense mechanism using cell-to-cell communication to 'warn' unaffected bacteria, which can then anticipate, shield themselves and spread the warning signal.

Selfish No More: Genetic Elements Give Phages a Competitive Edge

Curious bits of DNA tucked inside genomes across all kingdoms of life historically have been disregarded since they don't seem to have a role to play in the competition for survival.

Water-Soluble Bacterial Enzyme Could Enable Rapid Screening of Potential Antibiotics

A bacterial enzyme called histidine kinase is a promising target for new classes of antibiotics. However, it has been difficult to develop drugs that target this enzyme, because it is a "hydrophobic" protein that loses its structure once removed from its normal location in the cell membrane.

Novel Lipopeptide from Serratia marcescens Shows Promise Against Staphylococcus aureus Infections

A novel antibacterial lipopeptide produced by the bacterium Serratia marcescens has been shown to be highly effective in killing Staphylococcus aureus – one of the most important pathogens occurring in humans.

"Cervix-on-a-Chip" Offers Promise for New Bacterial Vaginosis Treatments

Bacterial Vaginosis (BV) has been identified as one of the many unmet needs in women's health and affects more than 25% of reproductive-aged women.

Plectasin's Velcro-Like Binding Holds Promise for Fighting Antimicrobial Resistance

A small antibiotic called plectasin uses an innovative mechanism to kill bacteria. By assembling into large structures, plectasin latches onto its target on the bacterial cell surface comparable to how both sides of Velcro form a bond.

Rice University Develops AI-Powered Tools for Unraveling Microbial Genomes

Since the first microbial genome was sequenced in 1995, scientists have reconstructed the genomic makeup of hundreds of thousands of microorganisms and have even devised methods to take a census of bacterial communities on the skin, in the gut, or in soil, water and elsewhere based on bulk samples, leading to the emergence of a relatively new field of study known as metagenomics.
