The 2025 ATS guidelines for community-acquired pneumonia update recommendations on imaging, antibiotic use, treatment duration, and corticosteroid use, emphasizing lung ultrasound as an alternative diagnostic tool, more selective empiric antibiotic prescribing, shorter courses of antibiotics for stable patients, and limited use of corticosteroids to severe inpatient cases.

A CDC report links the rapid growth of NDM-CRE to testing gaps and urges the prompt use of carbapenemase testing, mechanism-guided therapy, and stronger infection prevention measures.

This week, OPAT for gram-negative infections expands to outpatients amid infusion complexity and stability limits, HHS and CDC add five ACIP members days before meeting, and more.

Bordetella bronchiseptica is a rare human respiratory pathogen that can be initially confused for Bordetella pertussis, leading to potentially inadequate treatment. This article reviews the organism and recent literature on the successful treatment of B bronchiseptica.

In the second installment of an interview with Jacinda Abdul-Mutakabbir, PharmD, MPH, she continues the discussion around limited to no health care engagement due to these factors, and the importance of translating data from the bench to bedside when looking at disease and infection prevention.

Jacinda Abdul-Mutakabbir, PharmD, MPH, provides insights on her recently published study on this topic and how the 2 are connected.

In the midst of many changes surrounding aminoglycosides over the past several years, clinicians may be left wondering if these agents still have a role in modern clinical practice. This article summarizes changes impacting aminoglycosides, discusses where these agents may still have a role in the context of gram-negative infections, and explores future areas of study.

Compared to culture/sensitivity results (C/S) results, ICU-based PCR testing of hospital-acquired pneumonia was associated with lower treatment costs and better antibiotic stewardship, but not higher cure rates.
