The research was published this week in mBio, an open-access journal of the American Society for Microbiology.
Media Advisory: Commentary: FDA’s Ban on Triclosan Will Improve the State of Antimicrobial Resistance
Washington, DC – October 10, 2016 – The FDA recently released a final rule to ban triclosan and 18 other antimicrobials from household soaps. It is unfortunate that these chemicals have become common household products and have ended up as environmental contaminants. The ban is a move to correct that damage that has already been done, resulting from years of ticlosan and triclocarban usage, which will likely exert negative effects for years to come. Dr. Stuart Levy, a physician and researcher at Tufts University, and President of the Alliance for the Prudent Use of Antibiotics, says in a commentary that he applauds the rule because of the risks that triclosan poses to the spread of antibiotic resistance throughout the environment. The commentary is published October 10, 2016 in Antimicrobial Agents and Chemotherapy, a journal of the American Society for Microbiology.

The β-lactamase gene, blaVEB-2, has never before been found in V. parahaemolyticus, and in fact, has been found almost exclusively in non-marine pathogens. The research is published Monday, September 19, 2016 in Antimicrobial Agents and Chemotherapy, a journal of the American Society for Microbiology.
Protein Synthesis, ATP Unnecessary for Bacterial Spore Germination
Washington, DC - September 19, 2016 - Spores of Bacillus bacteria can survive for years in a dormant state, and then germinate in minutes. But it has long been unclear whether germination required protein synthesis, or cellular energy packets, which are known as ATP. Now, a team from UConn Health, Farmington, CT, has shown that neither is necessary. The research is published online September 19 in the Journal of Bacteriology, published by the American Society for Microbiology.
Microbes Corrode Steel in Ships, Marine Infrastructure
Washington, DC - September 16, 2016 - Rust is the bane of steel, whether on cars, on ships and boats, or as part of marine infrastructure. Now, contrary to previous thinking, it turns out that the ocean-dwelling, steel-corroding species, Mariprofundus sp. DIS-1, can thrive under aerobic conditions, rather than being limited to “micro-aerobic” or anaerobic conditions. That means steel in marine environments is more vulnerable to bacterial depredations than previously thought. The research is published on Friday, September 16th in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.
Molecules Released by Klebsiella pneumoniae Bacterium Pave the Way for Invasive Infection
Washington, DC – September 13, 2016 – It’s been known that the bacterium Klebsiella pneumoniae secretes small molecules called siderophores that enable it to acquire iron from a host and fuel its spread. Now, Michigan researchers have found that these molecules play additional roles in helping the organism invade. Their report is published this week in mBio®, an online open-access journal of the American Society for Microbiology.
Media Advisory: Longer Contact Times Increase Cross-Contamination of Enterobacter aerogenes from Surfaces to Food; Is the Five Second Rule Real?
Washington, DC – September 6, 2016 – Bacterial cross-contamination from surfaces to food can contribute to foodborne disease. Researchers from Rutgers University evaluated the cross-contamination rate of Enterobacter aerogenes using scenarios including four different surface types, (stainless steel, tile, wood, and carpet) four food types, (watermelon, bread, bread with butter, and gummy candy) four contact times, (<1, 5, 30 and 300 seconds), and two bacterial preparation methods. The researchers found that more bacterial transfer occurred during the longer contact times, but the type of food and surface type also significantly impacted cross-contamination from surface to food, with some transfers taking place instantaneously.
Chinese Investigators Characterize the World of Resistance Gene Exchange Among Bacteria
Washington, DC – September 9, 2016 – Certain antibiotic resistance genes are easily transferred from one bacterial species to another, and can move between farm animals and the human gut. A team led by Chinese researchers has characterized this “mobile resistome,” which they say is largely to blame for the spread of antibiotic resistance. They found that many antibiotic resistance genes that are shared between the human and animal gut microbiome are also present in multiple human pathogens. These findings are published September 9 in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.

Washington, DC – August 16, 2016 – A trio of researchers at the University of Texas Health Science Center, School of Public Health in Houston, have identified the location of the genes that control production of toxins that harm people infected by Clostridium difficile bacteria. The gene locus, agr1, forms part of a signaling communication system that produces a small molecule that, in turn, tells the rest of the population to turn on their toxin genes.
Investigators Chart Microbial Ecology of Gingivitis, Periodontitis
Washington, DC – August 12, 2016 – Gingivitis, a common and mild form of gum disease can progress to periodontitis, a more serious infection that damages the soft tissue of the gums and sometimes even destroys the bone supporting the teeth. An international team of researchers and clinicians has charted the microbial ecology of the mouth at all stages of this progression, in nearly 1,000 women in Malawi. This work is laying a foundation of knowledge that could lead to better oral health. The research is published August 12 in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.
New Model Sheds Light on Secondary Bacterial Pneumonia
Washington, DC – August 9, 2016 – For years, researchers have known that the bacteria Staphylococcus aureus (S. aureus) can trigger severe, sometimes deadly secondary bacterial pneumonia, in some people who are subsequently infected with influenza A virus, but scientists have not known exactly how this happens. Now, scientists have developed a new model for studying this phenomenon, which could lead to new treatments designed to prevent secondary bacterial infections. The findings were published this week in mBio, an online open-access journal of the American Society for Microbiology.
Mcr-1 Gene Isolated from Human for the First Time in Brazil
Washington, DC – August 8, 2016 – For the first time in Brazil, a particular antibiotic resistance mechanism conferring resistance to the important antibiotic, colistin, has been detected in a human. It was in a strain of Escherichia coli that was isolated from a diabetic patient’s foot infection. The mechanism, called MCR-1, was incorporated into a plasmid, a short piece of DNA that exists independent of the genome, which can jump from one bacterium to another, spreading the resistance. The research is published ahead of print August 8 in Antimicrobial Agents and Chemotherapy, a journal of the American Society for Microbiology.
ASM Urges Public Health Actions and Funding to Combat Zika Emergency
Washington, DC – August 5, 2016 – Current events linked to the Zika virus make aggressive public health actions and funding to combat this emerging infectious disease more crucial than ever. Newly reported Zika cases in Florida are the first examples of US infection spread by local mosquitos. On August 1 the Centers for Disease Control and Prevention (CDC) warned pregnant women and their partners against visiting a specific area with multiple cases in downtown Miami, an unusual federal advisory concerning a US community. Today Zika is so prevalent in Puerto Rico that only drastic measures will be able to control the epidemic. The 2016 Summer Olympics begin today in Rio de Janeiro, attracting large numbers of US athletes and spectators to a nation struggling with significant case numbers of Zika infection.
Additives to Boost Vaccine Responses Not Sufficient to Protect Obese Mice From Influenza
Washington, DC – August 2, 2016 – Adjuvants – ingredients added to vaccinations for influenza and other viruses to help boost their effectiveness – can increase a host’s immune response but not enough to protect the obese against the ill effects of the flu, according to a mouse study published this week in mBio®, an online open-access journal of the American Society for Microbiology.
Antibiotic Resistance Appears to Persist in Bacteria, Even Absent Selection Pressure From Antibiotics
Washington, DC – August 1, 2016 – Plasmids are pieces of independent DNA that often carry multiple antibiotic resistance genes. Plasmids can jump from one bacterium to another, spreading that resistance. A team of French investigators now shows that bacteria that acquire plasmids containing resistance genes rarely lose them. The research is published in Antimicrobial Agents and Chemotherapy, a journal of the American Society for Microbiology.
Green Monkeys Acquired Staphylococcus aureus From Humans
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.
Genes Found in H. pylori that Influence Biofilm Formation
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.
Progress Towards Protection from Highly Lethal Ebola, Marburg Viruses
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.
Self-Prescribing Antibiotics is a Big Problem
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.
New Resistance Gene Found in "High Risk" Multidrug-Resistant Pathogen
Washington, DC – July 11, 2016 – A team of Italian investigators has discovered a new variant of an emerging antibiotic resistance mechanism.

The research is published July 11, in Antimicrobial Agents and Chemotherapy, a journal of the American Society for Microbiology.
ASM Media Advisory: ASM No Longer Supports Impact Factors for its Journals
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 Spread
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.
Media Advisory: ASM Announces New President and Officers
Washington, DC - July 1, 2016 - The American Society for Microbiology is excited to announce the new officers whose terms will begin July 1st, 2016.

Cross-respiration Between Oral Bacteria Leads to Worse Infections
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.
Michigan Researchers Investigate What Causes Cattle to Shed STEC: Food Safety Could Benefit
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.
Beneficial Bacteria May Protect Breasts From Cancer
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.
