NewsStandard methodologies failing to accurately quantify fecal contamination across the globe, study warns
Standard risk assessment methodologies are significantly underestimating fecal indicator bacteria (FIB) loads in contaminated water, including recreational waters used for the 2024 Olympics, a new study reveals.

NewsPathogens that cling to microplastics may survive wastewater treatment
Wastewater treatment fails to kill several human pathogens when they hide out on microplastics in the water, reports a new study.

NewsNew bacterial toxins discovered: A key to fighting infections
Researchers have discovered a new group of bacterial toxins that can kill harmful bacteria and fungi, opening the door to potential new treatments. Found in over 100,000 microbial genomes, they can destroy the cells of bacteria and fungi without harming other organisms.

NewsChemical trick activates antibiotic directly at the pathogen
Scientists have seen promising results after experimenting with a click-to-release approach that deploys a masked form of colistin to the site of an infection so that it is no longer as damaging to the kidneys while maintaining its high antibiotic efficacy.
-
NewsBacteria thrive by playing nice before going their own way
A study tackles the question of how multiple bacterial species coexist in biofilms.
-
NewsBacterium becomes a permanent resident in a fungus
Researchers developed an innovative method for the precise implantation of bacteria into fungal cells and used evolutionary experiments to show how the symbiosis can be stabilised.
-
NewsGut bacteria engineered to act as tumor GPS for immunotherapies
Cancer researchers have engineered gut derived E. coli bacteria to express immune-activating cytokines on their surfaces, with the idea that the bacteria would move into tumors and induce potent immune responses.
-
NewsZooplankton go ‘Eew!’ to cleaning feces-contaminated water
Scientists were recently surprised to find that the natural community of zooplankton — tiny, aquatic animals known to graze on bacteria — present in freshwater and saltwater do not clean water that is contaminated with fecal microorganisms.
-
NewsScientists study how a bacterium becomes a permanent resident in a fungus
To study the beginnings of endosymbiosis between two organisms, a team of researchers initiated such partnerships in the laboratory and observed what exactly happens at the beginning of a possible endosymbiosis.
-
NewsRole of hydrogen sulfide in the expression of iron uptake genes is unveiled
Researchers have established the role of YgaV, a hydrogen sulfide dependent transcription factor, in regulating iron uptake dynamics in Escherichia coli.
-
NewsBioinformatics accurately detects short, fat antibiotic-resistant bacteria
Antibiotic-resistant bacteria exhibit characteristic morphological changes that can be detected microscopically in the absence of antibiotics using a bioinformatics approach.
-
NewsInnovative implant material combines osteogenic and antibacterial properties for superior bone repair
A new study introduces a novel polyetheretherketone (PEEK)-based implant material that not only promotes bone growth but also possesses potent antibacterial capabilities.

NewsStudy on E. coli outbreak in the UK demonstrates increasing impact of climate change on public health and food security
A study to investigate an UK E. coli outbreak identified contaminated lettuce as the most likely source of the infection, and determined that heavy rainfall and flooding may have carried STEC from animal feces to the lettuce crops.
-
NewsHydrometeorology and location affect hospitalizations for waterborne infectious diseases in the US
An analysis of 12 years of data collected from over 500 hospitals in 25 different states shows that weather, geographic location, and urban or rural location all appear to influence hospitalizations for waterborne infectious diseases.

NewsRaw meat based diets for pets are carrying multi-drug resistant pathogens
Raw meat-based diets for pets can serve as a vehicle for multi-drug resistant pathogens, posing significant risks to their owners, a new study has found.
-
NewsCoinfecting viruses impede each other’s ability to enter cells
Scientists researching phage infection at the level of a single cell investigated whether the number of infecting phages that bind to the bacterial surface corresponds to the amount of viral genetic material that is injected into the cell.
-
NewsCopper oxide nanoparticles to counter pathogens are synthesized from mango
Researchers have synthesized green copper oxide nanoparticles from Mangifera indica leaf extract. They showed potent activity against gram-positive and negative bacteria, as well as fungicidal effects on persimmon fruit pathogens.
-
NewsScientists uncover the microbial connection between urinary bladder and vagina
A new study highlights the association between urinary and vaginal pathogenic Escherichia coli in recurrent cystitis in postmenopausal women.
-
NewsEngineered nanovesicles from activated neutrophils show promise in treating infected wounds
A recent study has developed nanovesicles (NVs) from activated neutrophils, showcasing their ability to perform molecular debridement and accelerate healing in infectious wounds.
