For the First Time, Researchers Identify the Secret Genetic Weapon of Clostridium difficile

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.

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

New Compound Shows Promise Against Malaria

Washington, DC - June 6, 2016 - Malaria parasites cause hundreds of millions of infections, and kills hundreds of thousands of people annually, mostly in Africa. And in recent years the most dangerous malaria parasite, Plasmodium falciparum, has become increasingly resistant to the main anti-malarial drugs. Now, an international team of researchers shows that some members of a class of compounds called oxaboroles, which contain the element, boron, have potent activity against malaria parasites. The research is published ahead of print June 6 in Antimicrobial Agents and Chemotherapy, a journal of the American Society for Microbiology.

Crowds of Crows Spread C. jejuni: Are Humans Vulnerable?

Washington, DC - June 3, 2016 - Crows are smart, highly social animals that congregate in flocks of tens of thousands. Such large, highly concentrated populations can easily spread disease—not only amongst their own species, but quite possibly to humans, either via livestock, or directly. On the campus of the University of California, Davis, during winter, approximately half of the 6,000 American crows that congregated at the study site carried Campylobacter jejuni, which is the leading cause of gastroenteritis in humans in industrialized countries, which could contribute to the spread of disease.  The research is published ahead of print June 3 in Applied and Environmental Microbiology.

Study Shows How Bacteria Evolve in the Lungs of Cystic Fibrosis Patients

Washington, DC – May 24, 2016 – The bacterium Burkholderia multivorans evolves and adapts in bursts to survive in the lungs of cystic fibrosis patients, according to a study published this week in mSystems, an open access journal from the American Society for Microbiology. The work, believed to be the first retrospective look at the evolution of this microorganism, indicates that B. multivorans directly or indirectly targets adherence, metabolism and changes to the cell ‘envelope’ to stick around and evade antibiotics.

Temperature Influences Gene Expression, Life Cycle in Vibrio cholerae

Washington, DC – May 20, 2016 – Vibrio cholerae infects roughly four million people annually, worldwide, causing severe diarrheal disease, and killing an estimated 140,000 people. Its success as a pathogen belies the challenges this bacterium faces. The waters this bacterium inhabits when it’s not infecting H. sapiens can be 40 degrees Fahrenheit cooler than our normal body temperature. Now a team of investigators from the University of California, Santa Cruz provides new insights into how different temperatures in the bacterium’s environment control expression of genes required for life at those temperatures. The research is published ahead of print May 20 in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.

Mothers' Milk and the Infant Gut Microbiota: An Ancient Symbiosis

Washington, DC – April 15, 2016 – Nursing infants’ gastrointestinal tracts are enriched with specific protective microbes. Mother’s milk, itself, guides the development of neonates’ gut microbiota, nourishing a very specific bacterial population that, in turn, provides nourishment and protects the child. Now a team from the University of California, Davis, has identified the compound in the milk that supplies this nourishment, and has shown that it can be obtained from cow’s milk. This work could result in using cow’s milk to provide that compound as a prebiotic for infants. The research is published ahead of print on April 15th in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.

Cause of Maryland Food Poisoning Outbreak Traced to Asia

Botulism in Waterbirds: Mortality Rates and New Insights into How it Spreads

Washington, DC – March 25, 2016 – Outbreaks of botulism killed large percentages of waterbirds inhabiting a wetland in Spain. During one season, more than 80 percent of gadwalls and black-winged stilts died. The botulinum toxin’s spread may have been abetted by an invasive species of water snail which frequently carries the toxin-producing bacterium, Clostridium botulinum, and which is well adapted to wetlands polluted by sewage. Global warming will likely increase outbreaks, said corresponding author Rafael Mateo, PhD. The research was published March 25th in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.
