NewsEleven genetic variants affect the gut microbiome
In two new studies on 28,000 individuals, researchers are able to show that genetic variants in 11 regions of the human genome have a clear influence on which bacteria are in the gut and what they do there. Only two genetic regions were previously known.

NewsIncreased risk of severe bacterial infection after high teenage BMI
High BMI and poor physical fitness during later adolescence increase the risk of both contracting and dying from sepsis and other severe bacterial infections in adulthood, according to a study.

NewsWastewater from most countries favours non-resistant bacteria
Municipal wastewater contains a large range of excreted antibiotics and has therefore long been suspected to be a spawning ground for antibiotic-resistant bacteria. By testing the potential of untreated municipal wastewater from 47 countries to select for resistant E. coli, researchers show that while some samples indeed do so, most instead suppress them.

NewsNew role of gut bacteria provides hope for a novel IBS treatment
Research clarifies the complex interaction between gut bacteria and IBS, identifying two bacteria that together can produce serotonin: Limosilactobacillus mucosae and Ligilactobacillus ruminis.

NewsRegional differences in antibiotic use in newborns
There are relatively large regional differences in Sweden in the proportion of newborns receiving antibiotics for suspected sepsis, according to a study. The researchers want to call attention to overuse as well as highlight good examples.

NewsInfluenza virus hacks cell’s internal system
The influenza virus manipulates the body’s gene regulation system to accelerate its own spread, according to researchers. Their study shows that an already approved drug could help strengthen immune defenses—though its effect in humans remains to be confirmed.

NewsMulti-resistance in bacteria predicted by AI model
An AI model can predict whether bacteria will become antibiotic-resistant. The study shows that antibiotic resistance is more easily transmitted between genetically similar bacteria and mainly occurs in wastewater treatment plants and inside the human body.

NewsSmall antibody offers broad protection against influenza
Researchers have discovered an antibody-like molecule that can protect mice from various influenza viruses. The findings could pave the way for new treatments and the development of broader influenza vaccines.

NewsSwedish research on antibiotic pollution becomes UN declaration after 17 years
In 2007, researchers at the University of Gothenburg, Sweden published the first in a series of studies showing massive pollution with antibiotics from pharmaceutical factories in India. In connection with the ongoing UN General Assembly in New York, a declaration was approved that underlines the risks and calls for measures ...

NewsScientists reveal how bacteria in lakes fight climate change
Methane is a potent greenhouse gas frequently produced in the sea and in fresh water. Lakes in particular release large quantities of this climate-killer. Fortunately, however, there are microorganisms that counteract this: They are able to utilize methane to grow and generate energy, thus preventing it from being released into ...

NewsThe plague may have caused the downfall of the Stone Age farmers
Ancient DNA from bones and teeth hints at a role of the plague in Stone Age population collapse. Contrary to previous beliefs, the plague may have diminished Europe’s populations long before the major plague outbreaks of the Middle Ages.

NewsModel shows how plankton survive in a turbulent world
A researcher studying how particles move in turbulent fluids has created a model including various hydrodynamic factors to study how these particles handle and even utilise turbulence.

NewsScientists warn of overuse of antibiotics in newborns with suspected sepsis
Newborns in Sweden are given antibiotics for suspected sepsis to an unjustified extent, reveals a study of more than one million newborns. Despite a significant reduction in sepsis rate in the group, the use of antibiotics has not decreased.

NewsYeast and kelp flies can replace fishmeal in feed
Kelp flies and marine yeast cultivated on by-products from the seafood industry can be used in feed for farmed salmon.

NewsBeneficial gut bacterium can be made oxygen-tolerant
One of the beneficial gut bacteria residing in the human gut, which normally cannot survive in an environment with oxygen, can now be made oxygen-tolerant.

NewsFish farm poo can generate biogas
Digesting fish waste can allow circular fish and vegetable farms (aquaponics) to produce biogas that can be fed back into the energy system of these farms.
-
NewsPreviously unknown antibiotic resistance widespread among bacteria
A new study shows that bacteria in almost all environments carry resistance genes, with a risk of them spreading and aggravating the problem of bacterial infections that are untreatable with antibiotics.

NewsScientists find two separate reservoirs of latent HIV in patients
Scientists have shown that, addition to HIV’s ability to lay dormant in the blood/lymphoid system, the virus may also lay dormant in the central nervous system, delineating another challenge in creating a cure.

NewsAntibiotic resistance centre to expand to 150 researchers
The Center for Antibiotic Resistance Research (CARe) in Gothenburg is to expand, incorporating a broader base of partners and funders from January 1 2023, including Chalmers University of Technology, Sahlgrenska University Hospital and Region Västra Götaland.

NewsHolographic microscopy lifts lid on the life of microplankton
Researchers can follow the lives of microplankton at the individual level for the first time by making use of holograms created in digital microscopes and interpreted using artificial intelligence (AI).
