Small RNAs as emerging regulators of commensal adaptation in the mammalian gut
The commensal bacteria of the intestinal microbiota inhabit one of the most densely populated and dynamic microbial ecosystems known, where fluctuations in nutrient availability, host-derived stresses, and microbial competition require h...

Ecological drivers of Clostridioides difficile disease severity
Clostridioides difficile infection (CDI) is a common cause of antibiotic-associated diarrhea and arises from disruption of the resident microbiota in the gastrointestinal tract. Despite being a major cause of morbidity and mortality worl...

Efficient colonic colonization by Campylobacter jejuni requires the heme receptor ChuA
Previous research demonstrated that Campylobacter jejuni encodes a heme utilization system that facilitates heme-dependent growth under iron-limiting conditions, and that transcription of this system is induced during human infection. De...

PgaR is a positive regulator of the pgaABCD biosynthetic operon in Klebsiella pneumoniae
The biosynthetic locus encoding the exopolysaccharide poly-N-acetyl-glucosamine (PNAG) is widely conserved across bacteria, including the World Health Organization critical-priority pathogen Klebsiella pneumoniae (Kp). In Kp, PNAG synthe...

An intranasal bivalent vaccine induces antigen-specific humoral and Th1/Th17 cellular immunity and protects young and aged mice against MRSA and Pseudomonas aeruginosa skin and soft tissue infections
Staphylococcus aureus (SA) and Pseudomonas aeruginosa (PA) are ESKAPE pathogens that are responsible for severe skin and soft tissue infections (SSTIs), particularly in the elderly and those with immunocompromising conditions. Rising rat...

The interface of biofilm and immune system for Gram-negative ESKAPE pathogens
The ESKAPE group of pathogens comprises Enterococcus faecium , Staphylococcus aureus , Klebsiella pneumoniae , Acinetobacter baumannii , Pseudomonas aeruginosa , and Enterobacter spp., which are capable of developing profound biofilms wh...

Modulating innate immune responses to curli fibers through protein engineering
Curli fibers produced by Escherichia coli are functional amyloids that activate Toll-like receptor 2 (TLR2), initiating innate immune responses at mucosal surfaces. While microbiome-derived curli contribute to host-microbe interactions, ...

Flagellar regulation in enterotoxigenic E. coli modulates innate immune activation
Enterotoxigenic Escherichia coli (ETEC) remains a leading cause of diarrheal disease in low- and middle-income countries, yet vaccine efforts have struggled to achieve broad and durable protection. To better understand early steps in hos...

Host- and pathogen-regulated exocytosis facilitates dynamic distribution of endolysosomal content during infection by the vacuolar pathogen Coxiella burnetii
Coxiella burnetii is an obligate intracellular bacterial pathogen that causes the zoonotic disease Q fever. Coxiella extensively subverts host vesicle traffic and replicates within lysosome-derived, spacious vacuoles by secreting a suite...

Carbon and nitrogen sources can fuel fungal virulence
For all pathogenic microbes, metabolic processes are essential for growth, development, and survival during infection. However, host niches are dynamic environments where nutrient availability can vary, and host defense mechanisms often ...
