Genomic Insights Into Spatiotemporal Dynamics of Acquired Azithromycin Resistance Genes in Salmonella Strains Worldwide

Food Safety and Health, EarlyView.
ABSTRACT Azithromycin has been used for clinical invasive infections caused by fluoroquinolone‐ and third‐generation cephalosporin‐resistant Salmonella, and mass drug administration with azithromycin has been used to reduce under‐5 mortality in children in some countries.

Antibiotic Remodeling of the Gut Microbiota Impairs Host Resistance to Secondary Infection

iMetaMed, EarlyView.
Gut microbial dynamics induced by four antibiotics, revealed distinct taxonomic and functional shifts. Vancomycin‐perturbed bacteriomes were proven to promote pathogen resistance to antibiotic treatment. Metronidazole‐treated mice showed pronounced Salmonella translocation to hepatic tissue, and altered Enterococcus avium populations modulated host ...

Evaluation of Ceftriaxone as a Monotherapy and Amoxicillin With Clavulanic Acid as Combination Therapy in Surgical Prophylaxis

iNew Medicine, EarlyView.
ABSTRACT Surgical antibiotic prophylaxis (SAP) is crucial in preventing postoperative surgical site infections (SSIs), especially in clean and clean‐contaminated surgeries. It was a prospective comparative observational study that compared the effectiveness and safety of single‐dose ceftriaxone monotherapy with amoxicillin–clavulanic acid as a ...

Bacteriophage-derived endolysins restore antibiotic susceptibility in β-lactam- and macrolide-resistant Streptococcus pneumoniae infections

Streptococcus pneumoniae, the pneumococcus, is a cause of major illness globally. Invasive pneumococcal disease (IPD) is characterized by pneumococci invading blood (bacteremia), lungs (pneumonia), or brain and cerebrospinal fluid (meningitis ...

The Mechanisms of Reactions of β-Lactam Antibiotics

, 1987
This chapter explains that penicillin was the first naturally occurring antibiotic to be characterized and used in clinical medicine. It can be seen as the progenitor of the β-lactam family of antibiotics, which are characterized by the possession of the

Potent monoclonal antibodies against multidrug‐resistant hypervirulent Klebsiella pneumoniae

Interdisciplinary Medicine, EarlyView.
A novel immunization strategy using a low‐virulence, multidrug‐resistant strain yields synergistic monoclonal antibodies against hypervirulent Klebsiella pneumoniae. These antibodies provide cross‐serotype protection through a dual‐mechanism of pathogen clearance and immunomodulation, offering a promising non‐antibiotic therapeutic for resistant ...
