A new Applied and Environmental Microbiology report characterizes the ability of a bacterial compound to inhibit M. grisea growth, a characteristic that may prove useful in biocontrol of fungal infection of crops.

Microbiology Resource of the Month: ZetaHunter

Written by
"Some of the most impactful papers have been those describing resources," says Microbiology Resource Announcements EIC Irene Newton. Here, we introduce our Microbiology Resource of the Month, highlighting the ZetaHunter software made available by Clara Chan's lab at University of Delaware.
A new mBio article reports on a feature of C. auris that may contribute to its ability to cause serious disease: its ability to evade the innate immune system.
By day, Dr. Jeanne Jordan is a clinical virologist working in the School of Public Health at the George Washington University. But for 8 hours each month, she dons a safari-style vest to answer questions in the Smithsonian National Museum of Natural History’s newest exhibit, Outbreak: Epidemics in a Connected World. Learn about her science outreach experience in our interview.
What's hot in the microbial sciences? ASM summarizes microbiology news and reports in Microbial Minutes, a biweekly news roundup. This week: plants fix atmospheric nitrogen (with the help of microbes), the gut microbiome influences rotavirus vaccine efficacy, and a specific strain of Wolbachia blocks viral transmission in mosquitos - plus updates on measles and Florida's red tide!
Helicobacter pylori can survive the harsh environment of the stomach, where it uses its urease enzyme to neutralize stomach acid. A new Journal of Bacteriology study reports that urease plays double duty for the bacterium, and can also act as an antioxidant against reactive oxygen species.

E. coli maybe be associated with disease, but they are also an important component of the healthy human gut microbiome. Scientists used human volunteers to ask: what happens when resident, nonpathogenic E. coli meet pathogenic E.coli? Their results, in a new mSystems report, show a surprising resilience of the resident E. coli.
There is an acceptable range in microorganism concentration in cultures inoculated for antibiotic susceptibility testing. Could variability within this small range produce differences in susceptibility tests? A new Antimicrobial Agents and Chemotherapy report suggests it can.

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.

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.
