Antimicrobial resistance is one of the major problems in current practical medicine. The
spread of genes coding for resistance determinants among bacteria challenges the use of …

The β-lactams retain a central place in the antibacterial armamentarium. In Gram-negative
bacteria, β-lactamase enzymes that hydrolyze the amide bond of the four-membered β …

ABSTRACT β-Lactamases, the major resistance determinant for β-lactam antibiotics in Gram-
negative bacteria, are ancient enzymes whose origins can be traced back millions of years …

Klebsiella pneumoniae is a Gram-negative opportunistic pathogen responsible for a variety
of community and hospital infections. Infections caused by carbapenem-resistant K …

Klebsiella oxytoca is actually a complex of nine species—Klebsiella grimontii, Klebsiella
huaxiensis, Klebsiella michiganensis, K. oxytoca, Klebsiella pasteurii, Klebsiella …

It is well established that antibiotic treatment selects for resistance, but the dynamics of this
process during infections are poorly understood. Here we map the responses of …

The Enterobacteriales order consists of seven families including Enterobacteriaceae,
Erwiniaceae, Pectobacteriaceae, Yersiniaceae, Hafniaceae, Morganellaceae, and …

Carbapenemase producing Gram-negative pathogen is of great concern for physician. The
challenging aspects are treatment option and infection control. Monitoring of respective …

El mecanismo más importante de resistencia a carbapenémicos en enterobacterias es la
producción de carbapenemasas, aunque dicha resistencia también puede deberse a la …

A metagenomics approach was applied to explore the presence of antibiotic resistance
genes (ARGs) in bacteriophages from hospital wastewater. Metagenomic analysis showed …
