Colistin Does Not Potentiate Ceftazidime-Avibactam Killing of Carbapenem-Resistant Enterobacteriaceae In Vitro or Suppress Emergence of Ceftazidime-Avibactam Resistance [PDF]

Antimicrobial Agents and Chemotherapy, 2018
We tested ceftazidime-avibactam and colistin against 24 carbapenem-resistant Enterobacteriaceae (CRE) isolates by time-kill studies. Ceftazidime-avibactam at 0.25×, 1×, and 4× the MIC was bactericidal against 8%, 21%, and 88% of the isolates, respectively.

Emergence and Genomic Characterization of a Hypervirulent Klebsiella pneumoniae Isolate From a New Clone in Brazil

Microbiology and Immunology, Volume 70, Issue 5, Page 261-267, May 2026.
ABSTRACT Hypervirulent Klebsiella pneumoniae (hvKp) has emerged globally as a major public health concern, often associated with severe community‐acquired and healthcare‐associated human infections. Despite alerts from PAHO/WHO on convergent hvKp strains with multidrug resistance in Latin America, comprehensive data from Brazil, the region's largest ...

Ceftolozane–tazobactam- and ceftazidime–avibactam-resistant Pseudomonas aeruginosa mastoiditis

Access Microbiology, 2020
Pseudomonas aeruginosa is an important bacterial cause of a variety of infections and is associated with high morbidity and mortality. Infections caused by this bacterium are becoming more difficult to treat due to increasing resistance to many of the available antibiotics. Ceftolozane–tazobactam and ceftazidime–avibactam are two new

Antibiofilm activity of a chionodracine‐derived peptide by NMR‐based metabolomics of cell‐free supernatant of Acinetobacter baumannii clinical strains

FEBS Open Bio, Volume 16, Issue 4, Page 751-765, April 2026.
KHS‐Cnd peptide is able to impair biofilm formation and disaggregate mature biofilms in Acinetobacter baumannii clinical isolates. Differences in extracellular metabolites reflect changes in biofilm metabolism due to KHS‐Cnd treatment. Among the differentially represented extracellular metabolites upon KHS‐Cnd treatment, the significantly altered ...

An Unusual Case of Citrobacter koseri Infection During Pregnancy at 27 Weeks: A Case Report and Literature Review

Clinical Case Reports, Volume 14, Issue 4, April 2026.
ABSTRACT Early prenatal screening at 26 + 6 weeks detected Citrobacter koseri vaginal colonization in an asymptomatic high‐risk gravida. Culture‐guided IV ceftazidime (susceptible per CLSI testing) eradicated the pathogen without maternal/fetal compromise.

Ceftazidime/avibactam alone or in combination with aztreonam against colistin-resistant and carbapenemase-producing Klebsiella pneumoniae [PDF]

, 2017
The spread of carbapenemase-producing Klebsiella pneumoniae is a major public health concern since such isolates are basically resistant to most available antibiotics, including β-lactams, fluoroquinolones and aminoglycosides.1 Infections due to ...

Clinical Outcome Associated With Beta‐Lactam Allergy Labels in Hospitalized Patients in Belgium

Clinical and Translational Allergy, Volume 16, Issue 4, April 2026.
ABSTRACT Background In the United States, beta‐lactam allergy labels (BLAL) are documented in 9%–16% of hospitalized patients and associated with worse clinical outcomes such as increased mortality, length of hospital stay (LOS), intensive care unit (ICU) admission, and use of alternative antibiotics, providing an incentive for broad delabeling ...
