Multi-omics identification of molecular signatures of S. aureus adaptation to serum.
Metabolic versatility in carbon source usage, iron transport and resistance to oxidative stress is interlinked and central to S. aureus fitness in serum, representing potential S. aureus vulnerabilities that could be exploited therapeutically. #mSystems; asm.social/2Q8

ASM board members spent yesterday on Capitol Hill meeting with members of Congress and their staff, emphasizing the need for stable, full-year funding for science and public health agencies. See ASMโs FY2027 funding requests: asm.social/2Q4 #ASMAdvocacy
Had a really cool day advocating for microbiology research with @asm.org on the hill today. Staffers and the politicians I met with were very open and welcoming. Iโm remain hopeful we can make a difference.
Interaction of C. glabrata wild type and C. albicans yeast-locked efg1ฮฮ/cph1ฮฮ mutant cells with macrophages.
Should I stay or should I go? Research in #mBio suggests the fungus Candida glabrata may actively prolong the part of its life spent inside macrophages, which could contribute to immune evasion, antifungal resistance and potential recurrence of infection. asm.social/2Q2
Changes in body weight and temperature of guinea pigs in direct-contact and fecal exposure groups. Three guinea pigs were orally inoculated with 3 ร 105 TCID50/300 ฮผL of IDV D/CA.
Identified in 2011, respiratory influenza D virus (IDV) has been detected globally in bovine populations. This #ASMAnimalMicro article suggests IDV replicates in the GI tract but has limited ability for fecal-oral transmission in a guinea pig model. asm.social/2PZ

As editor in chief of @asm.org #mSphere sometimes I need to work at home on papers submitted to the journal. Knowing that we have a dedicated scientists who read our papers makes all the work worth it. Here's one of our dedicated readers
JB Editor's Pick: Westlake, Criss et al. show that the neuroendocrine hormone norepinephrine depresses the Fur operon of Neisseria gonorrhoeae, perhaps via direct demetalation of Fur, resulting in increased survival of this microbe.

Phage therapy offers a powerful tool against AMR infectionsโbut only if we move from isolated cases to coordinated systems. The first initiative of the ASM Health Unit, led by Colleen Kraft and Dev Mittar, will tackle this. Delighted by this scientific leadership, join us!

Barcode diversity is maintained in the URT but declines with increased distance from and branching of the main airways.
In a guinea pig model, H5N1 replicated in the nose, trachea and lungs when delivered intranasally, by aerosol or by transmission. In contrast, H3N2 stayed mostly in the nose, suggesting mode of exposure modulates within-host spatial dynamics. #JVirology: asm.social/2PE

Environmental microbiology connects climate change, the bioeconomy, and One Healthโbut not in the way most people think. Microbes control carbon, enable sustainable technologies, and shape health across ecosystems. Brian Badgley, Ph.D., explains why that matters now. www.youtube.com/watch?v=0fXq...
JB Editor's Pick: Iglesias, Mongiardini et al. show that loss of the Tad pili of B. diazoefficiens results in enhanced biofilm formation - they propose a regulatory role, perhaps via cdG, for Tad impacting biofilms in this bug.

Summary of host protease subversion by viruses to escape the antiviral activities of antibodies. Yellow background shows the role of soluble decoys in luring neutralization, promoting immune dysfunction, or revealing epitopes, which generate non-neutralizing antibodies. Blue background illustrates how protease-induced conformational changes modify/hide neutralizing epitopes. Green background summarizes how viral subversion of host proteases lowers effector functions against viruses or infected cells.
#MicrobiologyMonday: Viral infections can hijack host proteases to reduce antibody effectiveness. These proteases lob off viral antigens expressed on host cell membranes, creating soluble decoys that bind antibodies & reduce neutralization. #JVirology: asm.social/2Pn

Effect of IgM, IgG, and IgA on Cn morphology. (A) Scanning electron microscopy of Cn incubated for 48 h with (A and B) PBS (control), (C and D) IgA, (E and F) IgM, and (G and H) IgG. (B) Total cellular size of Cn after 48 h and (C) concentrations of Cn GXM shed (exo-GXM) into culture supernatant after 24 and 48 h. Statistical analysis was performed using a one-way ANOVA matched pairs and a Bonferroni multiple-comparisons test. Graphs show means ยฑ SD from at least three independent experiments. *Pโ<โ0.05 and **Pโ<โ0.03.
IgA has major effects on Cryptococcus neoformans (Cn) growth, morphology & protein synthesis, lending plausibility to the hypothesis that reported reductions in IgA levels in HIV-associated cryptococcal meningitis may influence Cn pathogenesis. #mBio: asm.social/2OV

Pregnancy-associated shifts in maternal microbiota across multiple body sites can signal to the placenta, influencing its function and fetal development.
Maternal microbial ecosystems are key in shaping reproductive physiology and pregnancy outcomes. While the gut microbiota has been extensively studied, the roles of microbes in other body regions are less clear. This #IAIJournal review provides insights: asm.social/2OQ
