Toxigenic C. difficile resides harmlessly in infants, poses risk to adults
Infants and toddlers frequently carry toxigenic Clostridium difficile, usually with no harm to themselves, but can serve as a reservoir and spread the bacteria to adults in whom it can cause severe disease, according to a study by a team of Swedish researchers published ahead of print in the Journal of Clinical Microbiology. (2013-12-03)

New technique identifies pathogens in patient samples faster, in great detail
A team of Danish investigators has shown how to identify pathogens faster, directly from clinical samples. The research, published online ahead of print in the Journal of Clinical Microbiology appears in the journal's Jan. 2014 issue. (2013-12-02)

New tales told by old infections
Retroviruses are important pathogens capable of crossing species barriers to infect new hosts, but knowledge of their evolutionary history is limited. By mapping endogenous retroviruses, retroviruses whose genes have become part of the host organism's genome, researchers at Uppsala University, Sweden, can now provide unique insights into the evolutionary relationships of retroviruses and their host species. The findings will be published in a coming issue of Proceedings of the National Academy of Sciences. (2013-11-25)

Lessons to be learned about influenza A, 4 years after the public alarm
With autumn just around the corner and a new flu strain lying in wait for us, the presentation of a study analyzing the management of the 2009 influenza A crisis could not, if anything, be better timed. The pediatrician Eider Oñate has just read her thesis in which she analyses how the H1N1 virus affected the pediatric population in Gipuzkoa during that period. (2013-11-22)

New method to diagnose sepsis is faster, cheaper
A new method could cut hours off the time it takes to diagnose blood infections while also eliminating the need for complicated manual processing and expensive equipment, according to a new report. The method combines a selective lysis step in which blood cells in the sample are destroyed, a centrifugation step to collect any bacteria or fungi in the sample, and a fluorescence step that analyzes the particular fingerprint of any pathogens present in the sample. (2013-11-19)

Probiotics reduce piglet pathogens
Piglets fed probiotic Enterococcus faecium showed reduced numbers of potentially pathogenic Escherichia coli strains in their intestines, according to a team of German researchers. The research is important, because in 2006 the European Union prohibited the feeding of antibiotics to livestock as growth promoters. Therefore, the research team sought to investigate whether probiotics could substitute for antibiotics, by reducing pathogen populations in the intestines. The study was published ahead of print in the journal Applied and Environmental Microbiology. (2013-11-14)

Small changes in ag practices could reduce produce-borne illness
Researchers from Cornell University have identified some agricultural management practices in the field that can either boost or reduce the risk of contamination in produce from two major foodborne pathogens: salmonella, the biggest single killer among the foodborne microbes, and Listeria monocytogenes. Their findings are published ahead of print in the journal Applied and Environmental Microbiology. (2013-10-21)

Men-only hepatitis B mutation explains higher cancer rates
A team of researchers has identified a novel mutation in the hepatitis B virus (HBV) in Korea that appears only in men and could help explain why HBV-infected men are roughly five times more likely than HBV-infected women to develop liver cancer. Although some women do progress to cirrhosis and liver cancer, the mutation is absent in HBV in women. The research is published ahead of print in the Journal of Clinical Microbiology. (2013-10-17)
