Meslinger har vært en fryktet og hyppig forekommende sykdom opp gjennom historien. I moderne tid og med effektiv vaksine falt forekomsten – men i senere år har man sett stadig flere tilfeller (og utbrudd), inkludert i Europa og USA. Ingrid, Jørgen og Nikolai snakker seg gjennom meslinger «fra tidenes morgen» og frem til i dag. Bli med på reisen!

Og - for infeksjonsmedisinsk helsepersonell som lytter til episoden våren 2025 - her er lenke til påmelding NSCMID: Home - NSCMID 2025.

Tyfus har satt sitt preg på både litteratur og historie - og Europakartet kunne kanskje sett annerledes ut var det ikke for denne vektorbårne bakterien.

Jørgen, Nikolai og Ingrid drar på reise igjen, denne gang for å finne ut av mer om tyfus om dens slektninger, rickettsiosene.

VI har dykket ned i flaggermusens underlige verden. Hvordan kan det ha seg at flaggermusen er bærer av (og tilsynelatende lever uaffisert med) en så lang rekke livsfarlige infeksjonssykdommer? Vi har fordypet oss i litteraturen og har dessuten snakket med forsker og virolog Irene Ørpetveit ved Veterinærinstituttet. Velkommen til en episode om flaggermusens mysterier!

Jonathan Stokes and his colleagues are discovering novel antibiotics through artificial intelligence (AI) - among others Halicin and Abaucin. This AI-driven research was named one of the years top discoveries by The New York Times in 2023. Stay tuned for a very futuristic - and inspiring - interview with a very interesting researcher!

Vi har vært på konferanse og intervjuet professor Jan Kristian Damås om gentamicin – et effektivt og i skandinavisk sammenheng hyppig brukt antibiotikum - men internasjonalt også mye debattert legemiddel.

Endokarditt er en sykdom som oftest krever intravenøs antibiotikabehandling i mange uker. De siste årene har imidlertid flere skandinaviske land innført tablettbehandling som et alternativ - og fra august er dette også kommet inn som et alternativ i de norske retningslinjene. Jørgen og Ingrid snakker med professor og endokardittforsker Magnus Rasmussen fra Lund om både om erfaringer med dette i praksis - og litt også om pågående forskning innen endokardittfeltet.
