Antimicrobial Resistance of Serratia marcescens Recovered From Aquatic Environments: A Review

Environmental Microbiology Reports, Volume 18, Issue 4, August 2026.
Serratia marcescens is a gram‐negative bacillus forming biofilms and showing multidrug resistance. Review (2019–2024) included 13 studies, 90 aquatic isolates. High resistance to β‐lactams, including carbapenems. Genes: blaOXA‐48, blaTEM‐1, aac(6′)‐Ic. Aquatic environments are reservoirs, requiring monitoring and control to prevent spread.

Enterococcus faecalis and Endodontic Treatment Failure: A Qualitative Systematic Review of Its Role and Elimination Strategies

Australian Endodontic Journal, Volume 52, Issue 2, Page 585-605, August 2026.
ABSTRACT The aim of this study was to synthesize evidence on the influence of Enterococcus faecalis on endodontic treatment failure and strategies for its elimination. This study followed the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) guidelines and was registered in PROSPERO (CRD420251022741).

Probable sepsis‐associated encephalopathy as a component of multiple organ dysfunction syndrome in a cat with pyothorax

Australian Veterinary Journal, Volume 104, Issue 8, Page 523-531, August 2026.
A 2‐year‐old male neutered domestic shorthair cat with bacterial pyothorax was referred to a tertiary hospital for treatment of sepsis. He met criteria for multiple organ dysfunction syndrome and developed new‐onset neurological dysfunction subsequent to the development of sepsis.

Rational Design, Synthesis, and Biological Evaluation of New Substituted Dihydropyrimidinones as Antibacterial Agents and β‐Lactamase Inhibitors

Chemical Biology &Drug Design, Volume 108, Issue 2, August 2026.
Novel 1,6‐dihydropyrimidinones act as antibacterial agents and beta‐lactamase inhibitors. Compounds 3d, 3i, and 7b demonstrated enhanced beta‐lactamase inhibition relative to the standard reference, clavulanic acid, demonstrating significant potentiation effects to restore antibiotic efficacy and combat resistant bacterial strains.

Hybrid Funnel Technique Reduces Marginal Bone Loss Versus Conventional Drilling: A 3‐Year, Prospective, Non‐randomized, Controlled Clinical Trial

Clinical Implant Dentistry and Related Research, Volume 28, Issue 4, August 2026.
ABSTRACT Purpose This study aimed to compare marginal bone loss (MBL) associated with Hybrid Funnel Technique (HFT) and conventional drill osteotomy for implant site preparation when bioactive implants are used, testing the null hypothesis that no significant differences occur at 1‐ and 3 years.
