CANS-seminar with professor Nicholas Feasey from the Liverpool School of Tropical Medicine.

“Antimicrobial resistance is predicted to impact most heavily on sub-Saharan Africa, yet how much is really known about clinical outcomes from drug-resistant infection in this setting? I will present observational data from multiple clinical cohorts recruited from Queen Elizabeth Central Hospital, Blantyre, Malawi and the surrounding communities in the Southern Region of Malawi.

I will describe the burden of AMR and DRI in this setting and the distribution of extended spectrum beta-lactamase producing bacteria in humans, animals and the environment. Lastly I will consider approaches to tackling AMR in Southern Africa.”

Although antibiotics target bacteria, their common side effect is the outgrowth of gut fungi. The use of antibiotics in infancy is connected to the risk of allergic diseases later in life, but the underlying molecular mechanisms remain vague.

Associate professor Veronika K. Pettersen at UiT and CANS has recently reported the consequences of fungal overgrowth in a mice model. While gut bacteria primarily communicate with the immune system via metabolites, gut fungi seemed to modulate the host cells through direct cell contact and fungal proteins in particular.

"Our results suggest that an increased abundance of certain gut fungal species in early life may affect the developing intracellular attributes of epithelial and immune cells."

The results from the study show that antibiotic use can be catastrophic for the maturing immune system by damaging chemical communication between the gut bacteria and immune cells.

The study was done during Veronikas postdoc stay at the University of Calgary in Canada. The paper was published online on Biomedcentral on 22 February 2022.

PhD Student  Jónína Sæunn Guðmundsdóttir has published her first articel in EBioMedicine  - Congratulations! 

Understanding drivers of antibiotic resistance evolution is fundamental for designing optimal treatment strategies and interventions to reduce the spread of antibiotic resistance. Various cytotoxic drugs used in cancer chemotherapy have antibacterial properties, but how bacterial populations are affected by these selective pressures is unknown. Here we test the hypothesis that the widely used cytotoxic drug methotrexate affects the evolution and selection of antibiotic resistance.

Hittil har Norge sluppet unna høye antall dødsfall forårsaket av resistente bakterier. Det skyldes både hell og dyktighet, tror seksjonsoverlege Arnfinn Sundsfjord hos 20-årsjubilanten K-res.

The CAS Board of Directors has selected two Young CAS Fellow projects for the period of January 2022 to December 2023. Veronika Kuchařová Pettersen, associate professor at UiT The Arctic University og Norway (UiT), will lead the Young CAS fellow project: Infant Gut Microbiome Acquisition: Off to a Healthy Start.

Siden 2012 har det vært en markant nedgang i total antibiotikabruk i Norge. Tallene fra NORM 2020 viser en reduksjon på 32 prosent. Les hele artikkelen i Dagens Medisin

Forskerne oppdaget bakterien ved en tilfeldighet. De skulle først og fremst studere hudbakterier som kan føre til alvorlige infeksjoner, spesielt hos fortidligfødte spedbarn.

Så dukket det en ny type bakterie opp i prøveglasset.

Forskerne har gitt den navnet Staphylococcus borealis fordi den er funnet i nord, og fordi den kan være tilpasset et nordlig klima.

Jonina Gudmundsdottir from the MicroPOP group has been selected by European Society of Clinical Microbiology and Infectious Diseases (ESCMID) as  one of “30 outstanding scientists 30 years of age or younger” to celebrate the 30th European Congress of Clinical Microbiology & Infectious Diseases (ECCMID) in Paris this April. Selected articipants will actively participate on social media, especially Twitter, during the congress, and they are also invited to submit a scientific abstract for inclusion in the ECCMID 2020 Abstract Programme. The congress is expected to gather more than 13000 participants. Congratulations, Jonina.
