(2018-11-13) WHO uppmärksammar antibiotika i november med den pågående World Antibiotic Awareness Week. Svenska forskare bidrar i år till ”World Antibiotic Awareness” med en avancerad kurs, 26-30 november, för framtidens forskare och läkare i Sverige. Kursen äger rum i Hindås, utanför Göteborg.
Under den första kursdagen, 26/11, är vetenskapsjournalister/representanter för media välkomna till information om den senaste forskningen kring antibiotikaresistens!
Antibiotikaresistens betraktas som ett av de största hoten mot människors hälsa och matförsörjningen världen över. I allt snabbare takt uppstår resistenta bakteriestammar och behandlingen av infektionssjukdomar så som tuberkulos, lunginflammation, gonorré och blodförgiftning blir allt svårare och ibland även tyvärr utan resultat. Befintliga antibiotika verkar inte längre, och flera multiresistenta bakterier kan spridas med resenärer till nya miljöer. Långa behandlingstider och svårare sjukdomsförlopp som kräver fler dödsoffer, resulterar i högre kostnader för sjukvården. Bara i Europa dör varje år 33 000 människor som en direkt följd av antibiotikaresistens, enligt en studie som nyss publicerades i tidskriften The Lancet.
MIMS and UCMR Researchers are funded by the Swedish Research Council for their participation in International research collaborations in two research consortia funded within the European Joint Programming Initiative on Antimicrobial Resistance (JPIAMR).
[2018-10-30] MIMS Group Leader and UCMR Researcher Vasili Hauryliuk, Department of Molecular Biology, is part of the project “Development of novel ribosome-targeting antibiotics” with collaborators in Germany, France, Czech Republic and Italy. Under the lead of Daniel Wilson at the University of Hamburg, the collaborating laboratories will focus on discovering novel antibiotics which are targeted towards the ribosome, the cellular protein fabric, which is one of the major target of existing antibiotics.
[2018-06-21] Scientists affiliated with MIMS and UCMR describe their findings about a new toxin and its secretion mechanism from the major bacterial pathogen Vibrio cholerae in a recent publication in the journal Communications Biology (7 June 2018).
The bacterium Vibrio cholerae was discovered more than 150 years ago but remains as one of the main causes of bacterial infectious disease globally, especially in low-income nations where it occurs endemic, and outbreaks of cholera disease can lead to major epidemics.
In addition to causing cholera disease characterized by very severe watery diarrhea, different variants of V. cholerae can cause, for example, wound infections and infections in the ear canal (ear inflammation). If the infection is reaching the bloodstream, it can lead to blood poisoning. Such variants of Vibrio bacteria are common in brackish water, but can be found both in freshwater and saltwater and are also present in such environments in our country.
Scientists from Umeå University have now discovered and characterised the structure and function of a so far unknown Vibrio toxin. A team led by Professor Sun Nyunt Wai at Department of Molecular Biology and MIMS used the worm Caenorhabditis elegans as a predatory host for the bacteria and identified by molecular genetic analysis the V. cholerae genes required for production and release of the new protein toxin, now called MakA.
World Antibiotic Awareness Week (WAAW) aims to increase awareness of global antibiotic resistance and to encourage best practices among the general public, health workers and policy-makers to avoid the further emergence and spread of antibiotic resistance.
Researchers (ca 50 research groups) at MIMS and UCMR work on the understanding of molecular mechanisms of microbial infections. The knowledge could be used to develop new antimicrobial strategies for future treatment of infections and to avoid antibotic resistance.
MIMS Deputy Director Maria Fällman will give a popular science lecture in Swedish language in the series of popular science lectures "lärande luncher" organised by the Norrland University Hospital.
Title: "Nya vapen mot seglivade bakterier"
Place: Frälsningsarméen, Umeå, Kungsgatan 47, 90326 Umeå

MIMS- scientist publish in the high-impact Journal of the International Society for Microbial Ecology, ISME.
An important survival strategy in bacteria is the release of toxic substances, which can attack and kill cells and other bacteria. One of these substances are D-amino acids, which are secreted to the environment at high concentrations by very diverse bacteria. D-amino acids interfere with the growth of neighboring competitors thereby improving the chances of producer species to colonize an specific niche. Felipe Cava's research group at The Laboratory for Molecular Infection Medicine Sweden (MIMS) studied the biological effects caused by distinct D-amino acids released by the causative agent of cholera, Vibrio cholerae. The study was performed in collaboration with Miguel A de Pedro, a former visiting professor at Umeå University and investigator at the Centro de Biología Molecular ‘Severo Ochoa’, CSIC in Madrid, Spain.
The scientists found that D-Arginine is a very potent and very broad growth inhibitor of many diverse bacterial species, including pathogenic ones such as Burkholderias, well known for their implication in pulmonary infections and their broad antibiotic resistance.
"We found that D-Arginine is a key environmental factor that controls both fitness and survival of bacterial subpopulations and therefore can modulate the existing biodiversity within an ecological niche" explains Laura Alvarez, postdoctoral researcher who conducted the study.
Alvarez and colleagues found, too, that although all the members of the Vibrionaceae family were resistant to D-arginine, not all of them produce this effector. This behavior suggests that a few vibrios may have evolved to help members of the family in an altruistic cooperation to facilitate prevalence of the entire vibrio in a particular ambient.
MIMS is looking for research-interested physicians in infectious medicine to join the MIMS Clinical Research Fellows Programme.
The Laboratory of Molecular Infection Medicine Sweden (MIMS) and Umeå Center for Microbial Research (UCMR) at Umeå University, are strong research areas, which are with the support of the Swedish Research Council (VR) strengthening career development in the microbiological and infection research field. Researchers at MIMS-UCMR combine strong research in molecular infection biology with, e.g. chemical biology or structural biology research to study molecular mechanisms of infections.
In order to further strengthen the link between clinical research on a national level, MIMS has initiated the Clinical Research Fellows (MIMS-CRF) programme http://www.mims.umu.se/clinical-research-fellows/about-mims-crf.html) that offers research resources to clinically active doctors.
We are now looking for research-interested physicians.
[2017-02-01] Major technical advances has enabled cryo-EM to become a mainstream technique in visualization of macromolecules, which provides the most definitive way to describe their mechanisms of action. The first international cryo-EM symposium in Sweden will take place in Stockholm and Umeå, and present the developments that are shaping this scientific breakthrough. Topics covered include central discoveries in cryo-EM, the most recent methodological developments and applications to central biological questions.
Note: the 1st day of the Symposium takes place on 8th of May 2017 at SciLifeLab, Stockholm.
Everybody is welcome!
Jubilee symposium to celebrate Knut and Alice Wallenberg Foundation's 100 years anniversary
To celebrate 100 years in support of excellent Swedish research and education, the Knut and Alice Wallenberg Foundation arranges, in collaboration with the Royal Swedish Academy of Sciences and the Swedish universities, a series of symposia in areas where the Foundation has provided substantial financial support throughout the years.
The six symposia have different focus and are organised in Lund (4 April), Umeå (June 19), Linköping (13 September), Stockholm (15 September), Uppsala (21 September), and Gothenburg (28 September).
The symposium in Umeå "Infection Research to Meet current and Future Challenges" will take place on:
19 June 2017, 08.45 - 17.20
