World Antibiotics Awareness Week, 13-19 November 2017

AMR Stamp 2WHO campaign 2017: Antibiotics: Handle with care

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.

Lessons from bacteria: Novel antimicrobial strategies based on interspecies metabolic cooperation

20171017 Aliashkevich Cava Alvarez 562 2MIMS- 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 Clinical Research Fellows Programme - new recruitments

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 that offers research resources to clinically active doctors.

We are now looking for research-interested physicians.

Exploring the Complexity of Life by Cryo-Electronmicroscopy

[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!

Infection Research to Meet Current and Future Challenges

J17 kaw 100ubilee 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:

Group picture UREM 2017 1More than 140 scientists started the new year with the UCMR DAY 2017, on 12th of January. In lively discussions the microbiologists spent the day not only with talks but also with mingling at the posters, during coffee and lunch breaks, updating themselves and guests about ongoing research projects.

Per Sunnerhagen, CARe Therapeutics, University of Gothenburg, and Linus Sandegren, Uppsala Antibiotics Center (UAC), presented the organisation an focus of their new Antibiotics Centres.

How the bacterial protective shell is adapted to challenging environments

Illustration JACS Publication Cavalab[2016-07-07] Researchers at Umeå University in Sweden have published new findings on the adaptation of the bacterial cell wall in the Journal of the American Chemical Society. The study reveals novel bacterial defence mechanisms against the immune system and how they can become resistant to antibiotics.

Bacteria are surrounded by a mesh-like structure which, similar to an external skeleton, defines the cell shape and provides protection against external attacks. This remarkable polymer cell wall called peptidoglycan, given its basic composition of sugars and amino acids, is well known for being a major target of beta-lactam antibiotics such as Penicillin.

Despite this structure having been the focus of extensive investigations on the long-lasting battle against bacterial pathogens (i.e. bacteria that cause infectious diseases), there is currently little understanding of its natural variability and the consequences of such changes on the ability of bacteria to adapt and survive in a threatening environment.
