Over half a billion people a year get some type of bacterial intestinal infection. By building their own intestines, so-called organoids, Mikael Sellin and his colleagues at IMBIM, Uppsala University can study how these infections occur.
Antibiotic resistance from random DNA sequences
An important and still unanswered question is how new genes that cause antibiotic resistance arise. In a new study, Swedish and American researchers have shown how new genes that produce resistance can arise from completely random DNA sequences. The results have been published in the journal PLOS Genetics.
Genome sequencing for more sustainable herring fishery
An international team of Swedish, Norwegian, Danish and Irish scientists has used whole genome sequencing to characterise 53 herring populations from the Atlantic Ocean and the Baltic Sea. They have developed genetic markers that make it possible to better monitor herring populations and avoid overfishing. The study is published in the journal eLife.

Rapid testing for antibiotic resistance
In cases of severe infection, identifying the correct antibiotic – and doing so quickly – can be a matter of life and death. At Uppsala University a very fast test for antibiotic resistance is being developed. The goal is to reduce the time from taking a sample to getting a result from one day to under four hours.
240 mammals help us understand the human genome
A large international consortium led by scientists at Uppsala University and the Broad Institute of MIT and Harvard has sequenced the genome of 130 mammals and analysed the data together with 110 existing genomes to allow scientist to identify which are the important positions in the DNA. This new information can help both research on disease mutations in humans and how best to preserve endangered species. The study is published in Nature.

The new method is simple for laboratories to use and can provide greater scope for customising treatment of bacterial infections. The study is published in PLOS Biology.
Genomic Analysis Reveals Many Animal Species May Be Vulnerable to SARS-CoV-2 Infection
För att i framtiden snabbt kunna hejda utbrott av covid-19 som orsakas av viruset SARS-CoV-2 och för att redan nu kunna skydda utrotningshotade arter som riskerar att drabbas, behövs kunskap om vilka djur som är tänkbara smittbärare av viruset. Professor Kerstin Lindblad-Toh vid Uppsala universitet och hennes kollegor har identifierat ett stort antal däggdjur som potentiellt kan smittas.

Intensive hunt for drugs to fight COVID-19
The entire world is currently waiting for a vaccine against COVID-19. Intensive research is ongoing to develop useful drugs against the novel coronavirus SARS-CoV-2. At Uppsala Biomedical Centre (BMC), substances are being tested that attack the same type of enzyme as drugs against HIV and hepatitis C.
Tests provide new picture of the spread of the virus
Two recent studies testing for antibodies against the coronavirus SARS-CoV-2 provide a new picture of the spread of virus in Sweden. “To gain a more realistic picture of the spread of the virus in Sweden, we need to perform more tests,” says Åke Lundkvist, professor of virology at Uppsala University.
How gene flow between species influences the evolution of Darwin’s finches
Despite the traditional view that species do not exchange genes by hybridisation, recent studies show that gene flow between closely related species is more common than previously thought. A team of scientists from Uppsala University and Princeton University now reports how gene flow between two species of Darwin’s finches has affected their beak morphology. The study is published today in Nature Ecology and Evolution.

“Lethal” mutation makes tuberculosis bacteria resistant to antibiotic
Antibiotic-resistant tuberculosis is a common and serious problem globally. In a new article, researchers from Uppsala University describe how tuberculosis bacteria that carries a mutation that in theory should kill them manages to stay alive. The researchers discovered that the same trick that kept the bacteria alive also made them resistant to a very important type of antibiotic.
Maria Letizia Di Martino has been awarded an ESCMID Research Grant 2020
Maria Letizia Di Martino has been awarded 20,000 € by ESCMID (European Society for Clinical Microbiology and Infectious Diseases). The project - Revealing the Shigella flexneri epithelial invasome in a human enteroid infection model - will provide a global map of the Shigella virulence factors required for infection of the human “mini-intestine” model. This will form a solid basis for future molecular studies of human shigellosis, a research field thus far hampered by the lack of physiological infection models.

High levels of hyaluronan polysaccharide in serum from patients infected with dengue virus predict severe disease and contribute to increased blood vessel leakage
Dengue virus infection is transmitted by mosquitoes and is increasing rapidly in the world due to global warming and travel abroad. The infection causes suffering, consumes medical care resources, and can sometimes develop into a deadly disease that, among other things. manifests itself in a greatly increased leakage in the blood vessels that leads to fluid loss. There is no effective dengue virus vaccine and no specific treatment for patients with dengue fever.
Bacterial Persisters Promote the Spread of Antibiotic Resistance Plasmids in the Gut
Antibiotic therapy of bacterial infections may fail either because the microbe becomes genetically resistant to the administered drug, or because it enters a slow growing antibiotic-tolerant state – a phenomenon known as ”persistence”.
How the herring adapted to the light environment in the Baltic Sea
The evolutionary process that occurs when a species colonizes a new environment provides an opportunity to explore the mechanisms underlying genetic adaptation,which is essential knowledge for understanding evolution and the maintenance of biodiversity. An international team of scientists, led by researchers from Uppsala University, Uppsala, Sweden, reports that a single amino acid change in the light-sensing rhodopsin protein played a critical role when herring adapted to the red-shifted light environment in the Baltic Sea. Remarkably about one third of all fish living in brackish or freshwater carry the same change. The study is published today in PNAS.

Svårdetekterad antibiotikaresistens underskattat kliniskt problem
I de flesta fall när en bakterie behandlas med antibiotika som den är känslig emot så fungerar behandlingen. Men ibland fungerar inte det valda antibiotikat och en av förklaringarna till detta är heteroresistens, ett fenomen som forskare vid Uppsala universitet tillsammans med kollegor vid Emory University i USA klarlagt i detalj i en ny studie.
