Shapeshifting behavior of E. coli may offer clues to combat urinary tract infections

Urinary tract infections are both very common and potentially very dangerous. More than half of all Australian women will suffer from a UTI in their lifetime, and nearly one in three women will have an infection requiring treatment with antibiotics before the age of 24.

Highly antibiotic-resistant strain of MRSA on pigs is capable of rapidly adapting to human hosts

A new study has found that a highly antibiotic-resistant strain of the superbug MRSA – methicillin resistant Staphylococcus aureus – has emerged in livestock in the last 50 years, probably due to widespread antibiotic use in pig farming.

Study opens a door to better understanding the role of viruses in ecology

The first discovery of viruses infecting a group of microbes that may include the ancestors of all complex life has been found, researchers at The University of Texas at Austin report in Nature Microbiology.

Study discovers microbial link between Western-style diet and colorectal cancer risk

New research builds the case that a Western-style diet - rich in red and processed meat, sugar and refined grains/carbohydrates - is tied to higher risk of colorectal cancer through the intestinal microbiota. Investigators from Brigham and Women's Hospital with collaborators looked at data from more than 134,000 participants from two U.S.-wide prospective cohort studies.

UC San Diego scientists report on the molecular impact of life indoors

Within and upon every human being reside countless microorganisms - the microbiota that help shape and direct the lives of their hosts. A similar phenomenon occurs between people, microbes and the homes they share.

CDC continues investigation of meningococcal disease outbreak among gay and bisexual men in Florida

The Centers for Disease Control and Prevention (CDC) continues its collaboration with the Florida Department of Health to investigate one of the worst outbreaks of meningococcal disease among gay and bisexual men in U.S. history.

Bacterium discovery helps to solve the puzzle of what factors limit cell size

On sunken leaves in the waters of a Caribbean mangrove swamp, researchers discovered a bacterium that challenges the prevailing view of bacterial cell size; counter to the notion that microbes are only visible with a microscope, this one – named Thiomargarita magnifica – is larger than all other known giant bacteria by ~50-fold, and can be seen by the naked eye, the study's authors say.

Study links post-COVID symptoms with alterations in gut microbiota

A team of scientists has recently highlighted the significance of gut microbiota alterations induced by SARS-CoV-2 in triggering post-COVID-19 symptoms.

New perspectives on C-section and microbiota in newborns

A new study pinpoints key questions and knowledge gaps that must be addressed in order to define microbiome deficits and their link to health outcomes in infants born by Cesarian section, but also to evaluate adequate clinical intervention strategies in this population.

New technology can revitalize the bactericidal effects of conventional antibiotics in MDR E.coli infections

A research team led by Professor Kelvin Yeung Wai-kwok from the Department of Orthopaedics and Traumatology, School of Clinical Medicine, LKS Faculty of Medicine, The University of Hong Kong (HKUMed) has designed a non-invasive technology to revitalize the bactericidal effects of conventional antibiotics in multidrug-resistant (MDR)Escherichia coli (E. coli)-associated deep tissue infections, such as urinary tract and peritoneal infections.

Bacteria causing typhoid fever are highly developing antibiotic resistance

Bacteria causing Typhoid fever are becoming increasingly resistant to some of the most important antibiotics for human health, according to a study published in The Lancet Microbe journal. The largest genome analysis of Salmonella enterica serovar Typhi (S. Typhi) also reveals that resistant strains - almost all originating in South Asia - have spread to other countries nearly 200 times since 1990.

Lack of biodiversity in the gut or elevated metabolites associated with heart failure severity

Some people who experience heart failure have less biodiversity in their gut or have elevated gut metabolites, both of which are associated with more hospital visits and greater risk of death, according to a systematic review of research findings led by Georgetown University School of Nursing & Health Study researchers and colleagues.
