NewsScientists reveal how deadly Marburg virus enters human cells, identify therapeutic vulnerability
Researchers found that the Marburg virus, one of the world’s deadliest pathogens, is unusually efficient at getting inside human cells. They also showed that the virus’s entry protein contains structural features that explain this efficiency and point to a strategy for blocking infection.

NewsEveryday foods could hide fungal risks for mothers and children
A collaborative, multi-institutional project will examine how exposure to zearalenone – a mycoestrogen produced by mold with estrogen-like activity – may affect pregnancy outcomes and children’s growth.

NewsHow one flu virus can hamper the immune response to another
Prior exposure to one strain of influenza virus may weaken children’s ability to mount an effective antibody response against their subsequent exposure to a different flu strain, according to a study.

NewsThe gut can drive age-associated memory loss
Scientists have discovered that the aging gastrointestinal tract produces specific molecules that blunt the activity of a key gut-brain neuronal pathway, leading to age-related cognitive decline in mice.

NewsResearch guides response to unprecedented 2023 E. coli outbreak affecting Calgary kids
Protocols developed by scientists informed care when hundreds of children were sick due to a severe strain of E. coli. Overall, 40 children were hospitalized, 21 developed HUS and nine required dialysis. The number of children who developed HUS was less than half of what would typically occur in an outbreak of this size.

NewsTicks carrying more than one pathogen are on the rise in US Northeast
Tick-borne diseases are on the rise in the northeastern US, with many ticks carrying more than one pathogen. Most commonly found together were Borrelia burgdorferi and Babesia microti. Co-infection with these two pathogens was more frequent than expected, approaching 11% by the end of the study.

NewsWebinar: Unraveling periprosthetic joint infection
The free ‘Unraveling Periprosthetic Joint Infection’ webinar on March 25 explores one of the most challenging complications in modern orthopedic medicine, sitting at the intersection of microbiology, surgery, and patient care.

NewsSevere COVID-19 and flu facilitate lung cancer months or years later, new research shows
Severe COVID-19 and influenza infections prime the lungs for cancer and can accelerate the disease’s development, but vaccination heads off those harmful effects, new research indicates.

NewsDengue vaccine remains 80.5% effective against severe cases after five years
The tetravalent dengue vaccine was 80.5% effective against severe dengue cases with warning signs over a five-year period. Overall, the vaccine was 65% effective in preventing symptomatic dengue (caused by any serotype) during the five years of monitoring.

NewsScientists design metal-enhanced biochar to boost clean hydrogen production from agricultural waste
A new study reports that specially engineered biochar made from agricultural waste could significantly increase biohydrogen production by improving the way microbes transfer electrons during fermentation.

NewsResearchers uncover how bacteria suppress immune defences in stubborn wound infections
A common bacterium can suppress the body’s early warning system in wounds, causing infections to persist and create an environment that allows other bacteria to take hold. Enterococcus faecalis releases large amounts of lactic acid in the wound, which lowers pH, weakens immune cells and prevents them from fighting an infection.

NewsIsland birds reveal surprising link between immunity and gut bacteria
Scientists have uncovered a hidden link between gut health and the immune system, all thanks to a tiny island bird. They collected the poo of the Seychelles warbler to analyse their gut bacteria – and found that their immune genes influence which gut microbes thrive.

NewsSeaweed has the potential to create a shield to block norovirus infection
Seaweed has certain properties which have the ability to create a shield within the human body, effectively blocking norovirus infection. Fucoidan, from brown seaweed, showed the strongest and most consistent blocking activity against two major norovirus strains, GII.4 and GII.17.

NewsAntibiotics can affect the gut microbiome for several years
Researchers have found strong links between a person’s history of antibiotic use and the composition of their gut microbiome, including the diversity of bacterial species.
-
NewsLow-cost preventive measures could mitigate spread of bacteria causing neonatal mortality
A new study found that a multifaceted infection prevention and control intervention could at least temporarily thwart outbreaks of infections from the Klebsiella pneumoniae bacterium.
-
NewsSpecific gut bacteria species linked to muscle strength
A species of gut bacteria called Roseburia inulinivorans is specifically associated with human muscle strength and improved muscular performance in mice, finds new research. R inulinivorans changes certain metabolic processes in muscle, and converts muscle fibres to ‘fast-twitch’ (type II).

NewsNew African species confirms evolutionary origin of magic mushrooms
A long-standing debate about the evolutionary origin of the world’s most widely cultivated ’magic mushroom’ – Psilocybe cubensis – may now have been settled. Scientists describe the discovery of a new species of magic mushroom from the grasslands of South Africa and Zimbabwe.

NewsBuilding protection against infectious diseases with nanostructured vaccines
Researchers have leveraged a recently developed highly versatile DNA origami nanotechnology that is both vaccine and adjuvant, named DoriVac, as an alternative to current vaccine platforms.

NewsGut bacteria drive process that protects colon tissue
Researchers have shown that the identity of distinct regions of the colon are regulated by the gut microbiome. They identified nicotinic acid, a molecule produced by certain bacteria in the gut microbiome, as a main driver of these regional differences in the colon’s sections.
