mBiosphere

Convening a session by proposing a topic and expert speakers may seem like a small part of a large conference like ASM Microbe. We spoke with Kathryn (K.T.) Elliott, whose proposal was accepted for ASM Microbe 2018, and whose entire conference experience was improved because of it.

Who Is Spreading Viruses without Knowing it?

Written by
How many adults are asymptomatically infected with a virus that could be passed on to others? A new mSphere study looked systematically at visitors to a New York City landmark to discern who had respiratory disease symptoms, and who tested positive for carrying a respiratory virus.
Can transgenic plants combined with the right microbes improve bioremediation of contaminated soils? A new Applied and Environmental Microbiology report suggests the answer for some organic chemicals is yes.
What's hot in the microbial sciences? ASM summarizes microbiology news and reports in Microbial Minutes, a biweekly news roundup. Watch the YouTube session for summaries and major findings, and read the reports and news stories for yourself below. 
Biological sex can alter infection by influencing the immune response, but what about influencing the microbial side? A new mSphere report shows that Neisseria gonorroheae has different gene expression pattern in males versus females - with implications for antimicrobial resistance gene expression.

Making sense of MRSA mechanisms without mec

Written by
Most methicillin-resistant Staphylococcus aureus (MRSA) strains are resistant because they’ve acquired a mec allele, which makes screening them as easy as a PCR reaction. But what about non-mec MRSA? A new Antimicrobial Agents and Chemotherapy study investigated nearly 300 MRSA isolates, characterizing the genetic diversity of non-mec strains. This characterization may identify common genetic mechanisms to improve molecular screening for all MRSA patients. 
Cytomegalovirus and other opportunistic infections are often thought to only have negative consequences for those experiencing overt disease symptoms. A new Journal of Virology study reports the effect of subclinical CMV infection on the rhesus macaque response to the flu vaccine, suggesting an influence of subclinical infections on host immunity.

Scientific Highlights of ASM Microbe 2018

Written by
We’ve compared ASM Microbe to Las Vegas and a multistage concert, in part because there are so many amazing scientific sessions occurring simultaneously that attendees must prioritize the sessions in their schedule. We’ve aggregated some of the best social media summaries of scientific presentations from the 2018 Microbe sessions.
Dietary fiber plays an important role in gut health, but new research from mSphere shows that not all sources play the same role: researchers found that specific starches select for different microbial communities.

Celebrating Global Health Accomplishments

Written by
Global health is a complex problem requiring collaborations between local, national and international groups. ASM is happy to celebrate its recent accomplishments achieved through the hard work of many collaborative efforts.
Before you start writing your manuscript, here are 5 questions to ask yourself that will help ensure a successful (and ethical!) road to publication.
Does eating more diverse foods increase fitness? The ability to use ethanolamine, a common molecule found in our gut, helps bacterial pathogens like Salmonella to colonize and cause infection. A new mBio report suggests the opposite is true in the commensal bacterium Enterococcus faecalis. 
What's hot in the microbial sciences? ASM summarizes microbiology news and reports in Microbial Minutes, a biweekly news roundup. Watch the YouTube session for summaries and major findings, and read the reports and news stories for yourself below. 
Small amounts of antibiotics used in farm animals may be present in animal manure, which is used as crop fertilizer. A new Applied and Environmental Microbiology report shows these antibiotics can affect the soil microbiome composition, potentially influencing crop growth.
A chlorine wash is used to decontaminate food, including produce, that may carry bacterial pathogens. A new mBio report describes how chlorine treatment may not kill bacteria, but instead induce a viable-but-nonculturable state. This means the bacteria may still be present but not detectable through culture techniques.

Can colistin resistance be reversed?

Written by
Colistin resistance is now a worldwide issue. New ASM Journal articles uncover the molecular mechanism of colistin resistance, and uncover a natural product that may act to reverse resistance and render colistin once more effective.

Join in the Track Hubbub at ASM Microbe-pa-looza!

Written by
The multiple simultaneous events at ASM Microbe mimic a multistage concert with many performing acts. This is exemplified by the Track Hubs, where interactive sessions are vying for your attention. Our Track Leaders talk about their favorite Hub events - which will you be attending?
What happens when uninfected cells meet several virus strains at once? A new Journal of Virology report asks this question using two different HPV strains. The report finds that some HPV strains are better at blocking superinfection with a second strain than others.
A new Antimicrobial Agents and Chemotherapy study reports a novel mechanism of ciprofloxacin resistance in Pseudomonas aeruginosa. Scientists identified a gene that phosphorylates the drug, inactivating its antibacterial activities.
An mBio report describes the first time an insect endosymbiont has been cultured in vitro. Culturing the Drosophila melanogaster endosymbiont bacteria, Spiroplasma poulsonii may allow the organisms to become the first genetically tractable insect-endosymbiont pair.
