NewsBacterial villain behind Lake Erie’s ‘potent toxin’ unveiled by study
In Lake Erie, cyanobacteria can proliferate out of control, creating algal blooms that produce toxins that can harm wildlife and human health. Researchers have IDed the organism responsible for the toxins: a cyanobacteria called Dolichospermum.

NewsProtein sources change the gut microbiome – some drastically
A new study shows that protein sources in an animal’s diet can have major effects on both the population and function of the gut microbiome. The two largest effects of dietary protein were on amino acid metabolism and complex sugar degradation.

NewsBacteria deployed as living test tubes to study human gene mutations
Bioengineers have developed a new simple approach to rapidly check on human gene changes and also screen chemicals as potential drugs by turning everyday bacteria into living test tubes.

NewsNew AI technique can uncover antiviral compounds using limited data
Artificial intelligence algorithms have been combined with traditional laboratory methods to uncover promising drug leads against human enterovirus 71 (EV71), the pathogen behind most cases of hand, foot and mouth disease.

NewsHerpesvirus protein mimics host enzyme to balance infection and latency
Researchers have uncovered a novel regulatory mechanism of CDK mimicry that may help herpesviruses coexist and expand within host cells while balancing host survival with viral persistence throughout the host’s lifespan.

NewsLong COVID biomarkers found – associated with respiratory problems
Researchers have identified biomarkers in the blood associated with symptoms of long COVID, particularly severe respiratory disorders. The discovery can pave the way for future diagnosis and treatment.

NewsCutting off parasite’s energy supply could help fight malaria
Once inside the body of an infected person, the malaria parasite relies on a process called glycolysis to produce energy and stay alive. Blocking the enzymes involved in this process could cut off the parasite’s primary energy source and kill it.

NewsNew study reveals emerging cases of babesiosis in Mid-Atlantic region
A newly published study provides critical insights into the emergence of babesiosis in the Mid-Atlantic region, documenting human cases and the presence of Babesia microti in local tick populations.

NewsChiral phytovirucide targets viral Nia protein to inhibit proliferation
A new study focuses on the search for small molecules to target the Nia protein of Potato virus Y (PVY), one of the most economically destructive viruses affecting Solanaceous crops such as potatoes, peppers, and tomatoes.

NewsResearchers reveal how human genetics and intratumoral microbiota affect colorectal cancer
A study shows that the single-nucleotide polymorphism (SNP) rs2355016—a tiny DNA change that some people carry—affects how intratumoral microbiota adhere to tumor cells, promoting colorectal cancer progression.

NewsBroader antibiotic use could change the course of cholera outbreaks, research suggests
Disease modeling research suggests that, for some cholera outbreaks, prescribing antibiotics more aggressively could slow or stop the spread of the disease and even reduce the likelihood of antibiotic resistance.
-
NewsNational-level actions effective at tackling antibiotic resistance
National-level policies can reduce the impact of antibiotic resistance across diverse countries, according to a new study. The comparison of countries found that national action was consistently associated with improved indicators of antibiotic resistance.

NewsA hidden control center: How bacteria regulate their attack strategies
Researchers have discovered that a key bacterial protein, CsrA, gathers in a droplet-like structure inside cells to control when and how bacteria activate their disease-causing genes.

NewsHuman protein HSF2 helps wake up sleeping cancer-linked viruses
A new study demonstrates the ability of the human protein HSF2 to remodel the viral DNA to enable the transition from dormant viral latency to active lytic reactivation.

NewsCOVID-19 vaccinations are metabolically safe, research finds
New research confirms that multiple doses of COVID-19 vaccines do not cause significant metabolic changes, offering reassurance for those concerned about potential long-term side effects of vaccination.

NewsNow is the time to strengthen infection prevention and control (IPC) programs in healthcare facilities
A joint position paper urges United States healthcare facilities to elevate the standards and effectiveness of their Infection Prevention and Control (IPC) programs.

NewsMeasles may be making a comeback in the US, research finds
If immunization rates drop further over a prolonged period of time, measles and even other wiped-out diseases — such as rubella and polio — could one day make a comeback in the United States, according to a new study.

NewsBacteria’s mysterious viruses can fan flames of antibiotic damage, according to new model
Researchers built a model that allows them to diminish phage communities from a mouse gut microbiome — and then bring them back — without affecting the bacteria. A test run found evidence that phages may increase gut bacteria’s sensitivity to antibiotics.
