The high frequency of ‘wine-type’ alleles in these regions is probably due to the arrival of wine immigrant strains introduced from Europe. However, in North and North-Eastern states, regions less suited for winemaking, wine-type alleles are much less frequent because ‘mestizo’ strains with intermediate or higher proportions of ‘native-type’ alleles are predominant.

Getting thirsty...

Green tea health benefits Green tea is a popular drink worldwide. Its consumption has been suggested to prevent the development of a variety of diseases, including diabetes, hypertension, cancer and cardiovascular diseases. Its effects are attributed to its abundant and biologically active catechin, epigallocatechin3-gallate (EGCG), which has antioxidative and antiinflammatory effects.

Studies have indicated that chronic inflammatory responses and oxidative stress conditions for example chronic infection with a periodontal pathogen, such as Porphyromonas gingivalis, is associated with an increased risk of atherosclerosis.

This Translational Research study demonstrates the ability of EGCG, apolyphenol extract from green tea, to protect against Porphyromonas gingivalis-induced atherosclerosis.

Highlighted article FEMS Ecology Bacterial invasion potential in water In drinking water (DW) and the distribution systems, bacterial growth and biofilm formation have to be controlled both for limiting taste or odour development and preventing clogging or biocorrosion problems.

After a contamination with undesired bacteria, factors like nutrient availability and temperature will influence the survival of these invaders. Invasion experiments with P. putida in oligo- to eutrophic waters showed the requirement of both a carbon and phosphate source for survival of P. putida. Experiments in surface water indicated the concomitant importance of the present indigenous microbial community of the specific water sample on the survival of P. putida.

The Swedish Society of Microbiology The Swedish Society for Microbiology (Svenska föreningen för mikrobiologi, SFM) is a life science membership organisation for individuals interested in microbiological sciences. The mission of SFM is to support the progress and growth of microbiology in Sweden.

SFM has currently about 280 members, located at universities, university colleges, research institutes and industry. The members of SFM represent a broad spectrum of subdisciplines, including general microbiology, molecular biology, microbial genetics, microbial ecology, microbial engineering, medical and veterinary microbiology, virology and immunology.

In order to fulfill the demands of all the different fields, SFM makes an effort to have a representation in the board from most of the various subdisciplines and universities in Sweden. The present board consists of Åsa Sjöling (Gothenburg), Ulrika Lustig (Uppsala), Magnus Evander (Umeå), Anders Bergqvist (Uppsala), Claes von Wachenfeldt (Lund), Staffan Svärd, (Uppsala), Öjar Melefors (Stockholm) and suppleants Nora Ausmees (Lund), Jonas Warringer (Gothenburg), Stefan Roos (SLU Uppsala) and Per-Eric Lindgren (Linköping).

SFM is also supporting other research conferences and workshops as well as travel stipends to national and international meetings for graduate students. SFM represents Sweden in IUMS, FEMS, EFB and other international societies.

SFM was founded in the early 1960s and joined FEMS in November 1974 on the first Council meeting where FEMS was founded. The second FEMS president was the Swedish professor Örjan Ouchterlony (1914-2004), professor at University of Gothenburg 1952-1980 where he founded the Department of Microbiology and Immunology.

Since then many famous Swedish microbiology researchers have been, or are, members of SFM and the society is aiming to continue to attract scientists in the field of microbiology and to be a vehicle for development of high quality fundamental and applied research among Swedish microbiologists.

The main activity of SFM is the annual research meeting “mikrobiologiskt vårmöte” (Microbiology Spring Meeting) that is arranged together with the other two major microbiology societies in Sweden, the National Society for Microbiology (RFM) and the Society for Medical Microbiology (FMM).

The spring meeting alternates between the Universities of Stockholm, Uppsala, Lund, Gothenburg, Umeå and Linköping and some of the newer universities and University colleges in Sweden.

The meeting facilitates national collaborations between the members of the different societies and universities as well as with local hospitals. SFM, RFM and FMM share a common website where information about the societies can be found.

FEMS-ESCMID Joint Fellowship FEMS and the European Society of Clinical Microbiology and Infectious Diseases (ESCMID) have a joint initiative to foster outstanding research in microbiology by young European scientists. Every year each organization selects one individual among the recipients of their respective research fellowship programmes to receive an additional amount of € 1000.

The fellows are chosen by the Boards of both organizations upon a two-way review process and are rewarded by this sum for their excellent research proposals. Due to its nature as a supplementary acknowledgement of excellent research, it is not possible to apply for this grant.

About ESCMID ESCMID is registered in Switzerland with offices in Basel. Since its founding in Germany in 1983, ESCMID has evolved to become Europe’s leading society in clinical microbiology and infectious diseases with members from all European countries and all continents. For more than 25 years, ESCMID has been an influential component in the professional lives of microbiologists and infectious disease specialists and now reaches more than 33’000 members and affiliated members around the world.

If all goes to plan a new injection would stop the need for annual flu jabs and could save thousands of lives every year. It could prevent highly dangerous forms of the disease, like the Spanish Flu. The universal vaccine works by attacking proteins hidden within the virus which are common throughout harmful strains. After testing, the vaccine could be available from 2018.
