Abstract:
Klebsiella pneumoniae poses significant global health challenges due to its increasing antimicrobial resistance (AMR). The emergence of multidrug-resistant (MDR) and carbapenem-resistant strains has limited treatment options, making infections difficult to control. This pathogen utilizes several mechanisms, including extended-spectrum β-lactamase (ESBL) production and efflux pumps, contributing to its resistance. Novel therapeutic approaches, such as bacteriophage therapy, CRISPR-Cas systems, and antimicrobial peptides, are being explored to combat AMR. Additionally, targeting virulence factors and biofilm formation holds promise for developing alternative strategies, providing a new frontier in tackling this formidable pathogen.

Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...
