Virulence Factors and Antibiotic Resistance of Strains Isolated From Neonates With Sepsis.

is one of the most important infectious agents in neonates. There are "classic" and hypervirulent strains of . The "classic" non-virulent strain of , producing extended-spectrum beta-lactamases (ESBLs), is associated with nosocomial infections.

Case of Meningitis in a Neonate Caused by an Extended-Spectrum-Beta-Lactamase-Producing Strain of Hypervirulent .

is one of the most important infectious agents among neonates. This pathogen has a potential to develop an increased antimicrobial resistance and virulence. The classic non-virulent strain of , producing an extended-spectrum beta-lactamases (ESBL), is associated with nosocomial infection mainly in preterm neonates.
