Seminal Fluid Increases Gonorrhea Infectivity
WASHINGTON, DC – March 4, 2014 – Researchers have come a step closer to understanding how gonorrhea infections are transmitted. When Neisseria gonorrhoeae, the bacteria responsible for gonorrhea, are exposed to seminal plasma, the liquid part of semen containing secretions from the male genital tract, they can more easily move and start to colonize. The research, led by investigators at Northwestern University in Chicago, appears in mBio®, the online open-access journal of the American Society for Microbiology.

Bacterial Toxin a Potential Trigger for Multiple Sclerosis
WASHINGTON, DC – January 28, 2014 – Researchers from Weill Cornell Medical College have added to the growing body of evidence that multiple sclerosis may be triggered by a toxin produced by common foodborne bacteria. The presented their research at the 2014 ASM Biodefense and Emerging Diseases Research Meeting.
Intranasal Vaccine Protects Mice against West Nile Infection
WASHINGTON, DC – January 28, 2013 – Researchers from Duke University have developed a nasal vaccine formulation that provides protective immunity against West Nile virus (WNV) infection in mice after only 2 doses. They present their findings at the 2014 American Society for Microbiology Biodefense and Emerging Diseases Research Meeting.
Salmonella Infection Mitigates Asthma: Research Could Lead to Treatments
WASHINGTON, DC – January 23, 2014 – Researchers from Germany have identified the mechanism by which Salmonella infections can reduce the incidence of asthma in mice. The research,which appears ahead of print in the journal Infection and Immunity, opens up new avenues of research that could lead to treatments.
Pathogenic Plant Virus Jumps to Honeybees
WASHINGTON, DC – January 21, 2014 – A viral pathogen that typically infects plants has been found in honeybees and could help explain their decline. Researchers working in the U.S. and Beijing, China report their findings in mBio®, the online open-access journal of the American Society for Microbiology.
ASM Statement on the FY 2014 Omnibus Appropriations Bill
WASHINGTON, DC – January 17, 2014 – The American Society for Microbiology (ASM), the largest single life sciences Society with 39,000 members, commends Congress on the passage of the omnibus spending bill funding the federal government through the rest of the fiscal year 2014. The passage of this bill represents a step in the right direction although funding for life sciences research is far from ideal, given the abundance of scientific opportunities and programs that cannot be funded and pursued.
Special Yeast Reduce Alcohol, Improve Wine
WASHINGTON, DC – January 16, 2014 – A team of Australian researchers has taken a giant step towards controlling a growing problem in the wine community. They have identified special yeast that produce a lower level of alcohol, helping to preserve the flavor. Their research is published ahead of print in the journal Applied and Environmental Microbiology.
Food Processors Beware: Salmonella Biofilms Incredibly Resistant to Powerful Disinfectants
WASHINGTON, DC – January 15, 2014 – Once Salmonella bacteria get into a food processing facility and have an opportunity to form a biofilm on surfaces, it is likely to be extraordinarily difficult, if not impossible, to kill it, according to research published ahead of print in the journal Applied and Environmental Microbiology.
Little But Lethal: Small RNAs Coordinate Bacterial Attack on Epithelial Cells
WASHINGTON, DC – January 14, 2014 -Two small RNAs (sRNAs) working in concert enable the deadly enterohemorrhagic Escherichia coli (EHEC) 0157:H7 to attach to and initiate infection in epithelial cells that line the digestive tract, according to a study published in mBioâ, the online open-access journal of the American Society for Microbiology.
