Clemson University researchers Anna Seekatz, PhD, and PhD candidate Sophie Millard uncover how functional mismatches between donor microbes and recipient gut environments could limit the success of microbiome-based therapies.

Findings from a multicenter US study confirm that RBL is a safe and effective microbiota-based therapy with sustained remission in a high-risk population with comorbidities.

Use of an AI-guided infection prevention bundle did not significantly reduce CDI incidence but was associated with increased antimicrobial stewardship.

Paul Feuerstadt, MD, FACG, AGAF, offers a glimpse of patients dealing with this and insights on improving patients’ quality of life, post-treatment with fecal microbiota, live-jslm (Rebyota [RBL]).

At ASM Microbe 2025, researchers underscored the role of NAAT in outpatient CDI diagnosis and raised concerns over PPI-related risk in older, health care–associated cases.

A study presented at ASM Microbe 2025 questions the clinical value of adding enzyme immunoassays to PCR-based CDI diagnostics amid sensitivity concerns.

Multiple studies highlight fidaxomicin’s effectiveness across high-risk populations despite cost and access challenges, underscoring the need for education and stewardship to improve guideline adherence.

At MAD-ID 2025, Jiye Park, PharmD, presents findings showing once-daily dosing is effective, with no added benefit from extended vancomycin use after antibiotics.

At MAD-ID 2025, Dakota Rorie, PharmD, highlights cost and access barriers to uptake of preferred CDI therapy.

At MAD-ID 2025, Rachel M. Kenney, PharmD, discusses treatment shifts, microbiome innovations, and pharmacists' roles in optimizing outcomes.

Environmental contamination plays a larger role than previously recognized, prompting calls for updated infection control strategies.

Lumen Bioscience’s LMN-201 was considered safe and well tolerated, and there were no severe dose-related or serious adverse events reported.

Study found that VRE colonization is linked to higher mortality, increased need for mechanical ventilation, and renal replacement therapy, while MRSA and C diff colonization showed less impact.

This week, a Mayo Clinic study found that removing C diff from gastrointestinal pathogen panels reduced unnecessary treatments, a Salmonella outbreak was linked to cucumbers, and a hepatitis C therapy achieved a 98% sustained virologic response in non-cirrhotic patients, among other developments.
