NewsCOVID-19 vaccination significantly reduces risk to pregnant women and baby
Pregnant women who received a COVID-19 vaccine were far less likely to experience severe illness or deliver their babies prematurely, according to a major new study.

NewsStrategic advancement of second-generation fungal vaccine VXV-01 through Phase 1 trials
The Lundquist Institute (TLI) and its start-up company Vitalex Biosciences (Vitalex) have announced that the second-generation fungal vaccine candidate known as VXV‑01 is poised to move forward in development up to and including Phase 1 clinical evaluation.

NewsA testing paradox for sexually transmitted infections
Surveillance evidence shows an increase in people infected with other STIs after initiating PrEP. A new study provides a counterintuitive explanation revealing a testing paradox: even when the observed cases increase, the true numbers of STIs can decrease.

NewsModulating key interaction prevents virus from entering cells
Researchers have found a way to modulate a common virus protein to prevent viruses from entering cells where it can cause illness. They were able to find and block an important interaction at the molecular level that allows the herpes virus to enter cells.

NewsImmune system keeps mucosal fungi in check
Researchers investigating the mechanisms that keep the fungus under control on our mucosa shed light on how homeostasis is maintained through the fine-tuned interplay between Candida albicans and the epithelial barrier on the one hand, and the immune system on the other hand.

NewsStreptococcus suis serotype 2 collagenase-like protease promotes meningitis by increasing blood-brain barrier permeability
Streptococcus suis serotype 2 (SS2) is an emerging zoonotic pathogen that causes meningitis in humans and pigs. Researchers have investigated the role and mechanism of the SS2 Clp in promoting the passage of the bacterium across the blood-brain barrier (BBB).

NewsMutated baker’s yeast at the forefront of petroleum substitute tech
Researchers engineering Saccharomyces cerevisiae to produce 2,3-butanediol (2,3-BDO) introduced mutations into the genomic DNA. The researchers engineered four altered strains and subjected them to ethanol, heat, and low pH stressors.

NewsSmarter tools for peering into the microscopic world
In a pair of new studies, researchers introduce powerful tools that make it easier, more accurate and more scalable to figure out how microbes are related. One tool improves how scientists build microbial family trees. The other provides a software foundation used worldwide to analyze biological data.

NewsHarmless Klebsiella strain shows powerful protection against gut infections in Inflammatory Bowel Disease (IBD) model
A new study demonstrates that a harmless strain of Klebsiella can eliminate infections and reduce gut inflammation in mouse models of inflammatory bowel disease (IBD).

NewsSwedish freshwater bacteria give new insights into bacterial evolution
Researchers analyzing the DNA of all known Caulobacterales species, including newly collected samples from Swedish and Finnish forest lakes, discovered that several freshwater species lacked more than a hundred genes typically linked to the group’s complex lifecycle.

NewsNovel kirkovirus may be associated with colitis in horses
In a pilot study, researchers have found a novel kirkovirus that may be associated with colitis – and potentially small colon impactions – in horses. The study could offer a route to new therapies for horses with colitis symptoms from unknown causes.

NewsFecal tests reveal active termite attacks
Termite pellets can linger long after the insects that dropped them have disappeared. By testing for microbes in the excrement, researchers can distinguish old droppings from fresh, and whether a colony is actively chewing its way through a home.

NewsStudy links gut bacteria to bloodstream infections in newborns within sub-Saharan Africa for the first time
New research has shown gut and bloodstream infections are caused by the same bacteria giving hope of better prevention and diagnosis of deadly neonatal sepsis.

NewsCould hidden infections be fueling long COVID?
For millions suffering from long COVID, their persistent breathlessness, brain fog and fatigue remain a maddening mystery, but microbiologists think they may have cracked the case. The review argues that co-infections acquired before or during COVID could cause symptoms to persist indefinitely for many people.

NewsEngineering oncolytic bacteria as precision cancer therapeutics
A new review summarizes recent advances in the design and application of synthetic biological strategies that enhance bacterial precision, safety, and efficacy in tumor therapy.

NewsApplications of AI in antimicrobial resistance prevention and control
Researchers have published a review shedding light on how AI is revolutionizing the prevention and control of AMR. The article illustrates how machine learning and deep learning are transforming surveillance, diagnosis, treatment optimization, and drug discovery.

NewsBacteria double as Trojan horse for artificial amino acids
Researchers have hijacked a natural transport system of the bacterium E. coli to develop a solution that allows artificial amino acids to be introduced into bacteria efficiently. This means the “amino acid toolbox” can be expanded for widespread use in medicine and the biotech industry.

NewsPersistent antibiotic resistance of cholera-causing bacteria in Africa revealed
In 2024, representatives from 14 African countries came together for a five-day intensive workshop on a whole-genome sequencing method called Oxford Nanopore Technology (ONT) aimed at strengthening cholera surveillance capabilities across the continent.
