Press Releases

Welcome to ASM's Newsroom, a resource for journalists seeking information relating to the microbiological sciences. Members of the media and the general public can access current and archived press releases highlighting the latest research published in ASM's journals or presented at our meetings.

Antibiotic use on people or pets, and use of biocidal cleaning products such as bleach, are associated with multidrug resistance in methicillin-resistant Staphylococcus aureus (MRSA) in the home. This contamination of the home environment may contribute to reinfection of both humans and animals with MRSA, and to subsequent failure of treatment. The research is published September 22nd  in Applied and Environmental Microbiology, a journal of the American Society for Microbiology. 

Researchers in the United Kingdom have discovered that the mix of microorganisms that inhabit a person’s saliva are largely determined by the human host’s household. The study, published this week in mBio®, shows that early environmental influences play a far larger role than human genetics in shaping the salivary microbiome—the group of organisms that play a crucial role in oral and overall health.

A mother and infant in Malawi have the same repertoire of antibodies to Plasmodium falciparum, the malaria parasite. That suggests that boosting the mother’s immune response to malaria, as via vaccination, will result in better protection for the infant. The research is published August 23rd in Clinical and Vaccine Immunology.

Researchers have demonstrated a new, improved version of the Xpert  MTB/RIF assay, a test for Rifampicin-resistance (RIF-R). The Xpert “Ultra” assay overcomes the shortcomings of the current Xpert assay to significantly improve tuberculosis detection.

Nearly 20 percent of women aged 15-29 are diagnosed with a urinary tract infection (UTI). Now, investigators have uncovered a rare mutation that renders a UTI-causing pathogen resistant to levofloxacin, a quinolone antibiotic used to treat UTIs. The research is published August 21st in Antimicrobial Agents and Chemotherapy, a journal of the American Society for Microbiology.

Epigenetic Drugs Show Promise as Antivirals

Written by

Some epigenetic pharmaceuticals have the potential to be used as broad spectrum antivirals, according to a study reported in a recent issue of the journal mBio. The study demonstrated that histone methyltransferases EZH2/1 inhibitors, which are being used in cancer clinical trials, have activity against a variety of viruses, including herpes simplex virus (HSV).

Specially designed plastic films can prevent bacterial contamination in the food and biomedical industries, according to research published August 11 in Applied and Environmental Microbiology.

A team of US researchers has discovered that three different species of Klebsiella bacteria can cause life-threatening infections in hospital patients and that all three share genes that confer resistance to the most commonly used antibiotics. 

For the first time, researchers have used whole genome sequencing to identify the cause of a zoonotic infection that sparked a national epidemic.

This week in mBio, an international group of scientists report on laboratory experiments suggesting that a novel LpxC inhibitor can treat multi-drug resistant bacterial infections, including many that originate in hospitals.

Couples who live together share many things: Bedrooms, bathrooms, food, and even bacteria. Microbial ecologists at the University of Waterloo, in Canada, found that people who live together significantly influence the microbial communities on each other's skin.

Researchers have found that the microbes inhabiting a hydraulically fractured shale formation produce toxic, corrosive sulfide through a poorly understood pathway. The team’s findings, published this week in mSphere®, an open-access journal of the American Society for Microbiology, reveal that the oil and gas industry may need new ways to monitor and mitigate sulfide-producing bacteria in fractured shales.

Pregnant women with a previous history of herpes simplex virus type 1 (HSV-1) infection maintain active antibodies against the virus, and researchers have found that this protection can pass to the nervous systems of their offspring.

Researchers have now discovered a new mobile colistin resistance gene, mcr-3, in E. coli of pig origin.

Toxins produced by three different species of fungus growing indoors on wallpaper may become aerosolized, and easily inhaled. The findings, which likely have implications for “sick building syndrome,” were published in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.

Canadian researchers have generated both novel and existing antibiotic resistance mechanisms on experimental farmland, by exposing the soil to specific antibiotics. 

Using high magnification imaging, a team of researchers has identified several never before seen structures on bacteria that represent molecular machinery. 

The pathogen, Vibrio cholerae can colonize the surfaces, as well as the intestines of soft shelled turtles. This finding is strong evidence that soft shelled turtles in China, where they are grown for human consumption, are spreading cholera. The research is published in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.  

University of Florida researchers may have come a step closer to finding a treatment for a disease called Huanglongbing, or citrus greening, that has been decimating citrus trees in the state.

Research presented at the ASM Microbe 2017 meeting showed a new Zika virus vaccine that gives 100% protection in mice.
