Washington, DC – July 29, 2016 - Many deadly diseases that afflict humans were originally acquired through contact with animals. New research published in ASM’s Applied and Environmental Microbiology shows that pathogens can also jump the species barrier to move from humans to animals. The study, that will publish July 29, shows that green monkeys in The Gambia acquired Staphylococcus aureus from humans.
Washington, DC – July 18, 2016 - Most bacteria cannot survive in the acidic environment of the human stomach, but Helicobacter pylori, a major cause of ulcers, thrives under such circumstances. Now research has shown that one of that bacterium’s regulatory proteins that helps it adapt to these stressful conditions also regulates the formation of biofilms. Biofilms, a group of bacteria that adhere together on a surface, are often much harder to kill than bacteria in their normal, disaggregated state, and can cause major medical problems. The research is published in the Journal of Bacteriology, a publication of the American Society for Microbiology.
Washington, DC – July 12, 2016 – Ebola and Marburg filovirus disease outbreaks have typically occurred as isolated events, confined to central Africa. However, the recent Ebola epidemic spread to several African countries, and caused 11,000 deaths. That epidemic underscored the need to develop vaccines and therapeutics that could be used to fight future disease outbreaks. Now new research suggests that antibodies to filoviruses from individuals who have survived these diseases may offer protection—not only against the particular filovirus that infected an individual, but against other filoviruses, as well. The research is published in Clinical and Vaccine Immunology, a journal of the American Society for Microbiology.
Washington, DC – July 11, 2016 - Five percent of adults from a cohort of 400 people reported using antibiotics without a prescription during the previous 12 months. Twenty-five percent said they would use antibiotics without contacting a medical professional. These findings demonstrate yet another factor abetting the spread of antibiotic resistance. The research is published ahead of print July 11 in Antimicrobial Agents and Chemotherapy, a journal of the American Society for Microbiology.
Washington, DC – July 11, 2016 - The editors-in-chief of ASM journals and ASM leadership have decided to no longer advertise the impact factors of ASM journals on the journals’ websites. This decision was made in order to avoid contributing to a distorted value system that inappropriately emphasizes high IFs. High-IF journals limit the number of accepted articles to create a perception of exclusivity, and individuals receive disproportionate rewards for articles in high IF journals, while science as a whole suffers from a distorted values system and delayed communication of research.
Colistin-Resistant Gene Detected in the U.S. for the Second Time: Investigators Alert to Its Possible SpreadWritten by Joanna Urban
Washington, DC - July 11, 2016 - For the second time, a clinical isolate of a bacterial pathogen has been detected in humans in the United States which carries the colistin resistance gene, mcr-1. This may also be the first case to show up in the US. That would be concerning because plasmids, genetic elements that are independent of the host genome, often jump between different bacterial species, spreading any resistance genes they carry. The research, the most comprehensive and contemporary surveillance data for mcr-1 to date, is published July 11 in Antimicrobial Agents and Chemotherapy, a journal of the American Society for Microbiology.
Washington, DC – July 11, 2016 – A team of Italian investigators has discovered a new variant of an emerging antibiotic resistance mechanism. The new variant, dubbed mcr-1.2, confers resistance to colistin, a last-resort antibiotic against multidrug-resistant Gram-negative pathogens. The research is published July 11, in Antimicrobial Agents and Chemotherapy, a journal of the American Society for Microbiology.
Washington, DC - July 1, 2016 - The American Society for Microbiology is excited to announce the new officers whose terms will begin July 1st, 2016.
Washington, DC – June 28, 2016 – Boston’s subway system, known as the T, might be just as bacteria-laden as you’d expect but organisms found there are largely from normal human skin and incapable of causing disease, according to a study published June 28 in mSystems, an open access journal of the American Society for Microbiology.
Washington, DC - June 28, 2016 - Researchers have discovered how the bacteria Group B streptococcus (GBS) avoids detection by the immune system during pregnancy. The findings, reported in the journal mBio, could lead to the development of new drugs and strategies for treating GBS infection, which is a leading cause of neonatal morbidity and mortality.
Washington, D.C.—June 28, 2016—Researchers determined that two bacterial species commonly found in the human mouth and in abscesses, cooperate to make the pathogenic bacterium, Aggregatibacter actinomycetemcomitans, more infectious. Key to the cooperation is that the harmless partner provides the pathogen with an oxygen-rich environment that helps it flourish. The findings, published this week in mBio, an online open-access journal of the American Society for Microbiology, could lead to better ways to fight the majority of bacterial infections that play out within complex communities of bacteria.
Washington, DC - June 24, 2016 - Shiga toxin-producing Escherichia coli (STEC) are foodborne pathogens spread largely by cattle, that can cause hemorrhagic colitis and kidney failure. In an effort to find ways of reducing this problem, Michigan State University investigators show that stress, and the negative energy balance associated with lactation appear to encourage the shedding of STEC, especially in summer. The research is published ahead of print June 24 in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.
Washington, DC - June 24, 2016 - Bacteria that have the potential to abet breast cancer are present in the breasts of cancer patients, while beneficial bacteria are more abundant in healthy breasts, where they may actually be protecting women from cancer, according to Gregor Reid, PhD, and his collaborators. These findings may lead ultimately to the use of probiotics to protect women against breast cancer. The research is published in the ahead of print June 24 in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.
Weekly Injections Could be used as a Standalone Treatment for Human Immunodeficiency Virus (HIV) PatientsWritten by Joanna Urban
Boston, MA – Monday, June 20, 2016, 9:00 am EST – Research being presented at the ASM Microbe meeting looks at a humanized monoclonal antibody, PRO 140, as a standalone treatment for patients with an HIV infection. Data from a phase 2b trial of PRO 140 will be presented that suggests an alternative to the current standard of care, which is antiretroviral therapy or ART.
A Novel Therapy for Genital Herpes Engages Immune Cells to Provide Significant Patient Benefits for at Least a YearWritten by Joanna Urban
Boston, MA – 12:30 pm, Monday, June 20, 2016 – A phase II clinical trial demonstrated that a new type of treatment for genital herpes, an immunotherapy called GEN-003, may reduce the activity of the virus and the number of days with recurrent herpes. This effect of treatment, given by a series of three injections, appears to last for up to at least one year. The research is presented at the ASM Microbe research meeting in Boston.
Washington, DC - June 20, 2016 - Lychnopholide, a substance isolated from a Brazilian plant, and formulated as part of “nanocapsules” cured more than half of a group of mice that had been infected experimentally with Chagas disease parasites. “Chagas disease affects millions of people, mainly in poor rural areas of 21 Latin American countries,” said Marta de Lana, PhD. The research is published in online ahead of print June 20 in Antimicrobial Agents and Chemotherapy, a journal of the American Society for Microbiology.
Boston, MA – 12:30 pm, Sunday, June 19, 2016 – Research at the ASM Microbe research meeting in Boston presents a sediment Microbial Fuel Cell (sMFC) system for remotely investigating the physiology and ecology of electrically active microbes in submerged field sites. Depending on the depth at which device components were submerged, scientists observed variation in start-up time and electricity generation.
Boston, MA – 5:00 pm, Sunday, June 19, 2016 – Research being presented at the ASM Microbe research meeting provides clear evidence that the gloves of healthcare workers contaminate hospital surfaces with bacteria. The researchers’ data also suggest that types of bacteria may affect cross-transmission rates among contaminated gloves and the hospital surfaces.
Boston, MA – 12:30 pm EST, Sunday, June 19, 2016 – Research presented at the ASM Microbe research meeting demonstrates a new way bacteria can cause dramatic morphological changes in human cells. Specifically, the researchers discovered that a common bacterial contaminant of contact lenses and cases can cause the formation of large bubble-like membrane structures on human ocular cells, which can contribute to contact lens wear complications and inflammation.
Boston, MA – 12:30 pm, Friday, June 17, 2016 – Research presented at the ASM Microbe research meeting provides compelling evidence that children acquire Streptococcus mutans, the bacterium most frequently associated with dental caries, from intra- and extra-familial sources besides their mother.
