Antibiotic resistance can vary depending on where the bacteria live

Research shows that bacteria harbor resistance genes may respond differently to antibiotics under non-standard conditions. This affects treatment efficacy and contributes to understanding antimicrobial resistance development and spread. Understanding these variations is crucial to combat global public health threats.

Rhododendron-derived drugs now made by bacteria

Kobe University scientists have engineered bacteria to produce a group of compounds with promising pharmacological activities. The breakthrough uses a rational design strategy to create a platform for industrial production of drug candidates.

Molecular knitting machine for bacterial capsules in 3D

Scientists at HZI have developed a new technique to visualize the complex process of bacterial capsule production. They used cryo-electron microscopy to study the Wza-Wzc transport channel, which is responsible for knitting the sugar cloak that protects bacteria from the environment and immune cells.

Bacterial hitchhikers can give their hosts super strength

A Dartmouth study found that plasmids can form tight clusters within bacterial communities, making them resistant to antibiotics and clinical treatments. This phenomenon introduces a new avenue for bacterial infections to become more difficult to treat.

Multiresistant intestinal bacteria: Displacement through food competition

A study by HZI researchers showed that specific strains of E. coli can displace multi-resistant bacteria from the gut, potentially preventing infections and containing their spread. The strains, which were tested in a mouse model, also proved effective against other resistant strains when combined with Klebsiella oxytoca.

Scientists reveal new toxin that damages the gut

Researchers at La Trobe University have discovered how enteropathogenic E. coli (EPEC) bacteria use a molecular toxin called EspC to destroy gut cells. This breakthrough could lead to the development of targeted drugs to combat EPEC infections and their devastating consequences, including severe dehydration and death.

Extreme rain heightens E. coli risks for communities of color in Texas

Research led by the University of Michigan reveals that extreme rainfall disproportionately increases E. coli concentrations in recreational waters of communities of color in Texas, particularly those with higher percentages of Black residents in the north and east, and predominantly Latino communities in the south and west.

Tiny dancers: Scientists synchronise bacterial motion

Researchers at Delft University of Technology discovered that E. coli bacteria can synchronise their movements by trapping individual cells in micro-engineered cavities and coupling them through narrow channels. The team observed coordinated bacterial motion and found that the synchronized movement adhered to universal mathematical rules.

Enterococcus helps E. coli ‘armor up’ in dog, poultry co-infections

A new study finds that Enterococcus faecalis produces protective capsular slime when present with certain strains of pathogenic Escherichia coli, making E. coli more resistant in low-iron environments. This discovery could lead to the development of targeted therapies for specific dog and poultry infections.

Bacteria ditch tags to dodge antibiotics

Researchers found that bacteria like E. coli assemble new ribosomes with altered tags, making them more resistant to antibiotics streptomycin and kasugamycin. This novel mechanism of antibiotic resistance could have significant implications for the fight against global antimicrobial resistance.
