Increase and diversity of carbapenemase-producing isolates, Italy.

This study reports on a surveillance in an Italian hospital focused on carbapenemase-producing (CP-Ec). Eighteen isolates (nine from clinical specimens and nine from rectal swab) were characterized for antibiotic susceptibilities, typing features, main carbapenemase, extended-spectrum ß-lactamases (ESBLs) and other genes, and their transferability by conjugation and transformation. An increase in CP-Ec isolates was observed during 3-year surveillance period.

Efficacy of carvacrol against resistant rapidly growing mycobacteria in the planktonic and biofilm growth mode.

Rapidly growing mycobacteria (RGM) are environmental bacteria found worldwide with a propensity to produce skin and soft-tissue infections. Among them, the most clinically relevant species is Mycobacterium abscessus. Multiple resistance to antibiotics and the ability to form biofilm contributes considerably to the treatment failure.

Chemical composition of Pistacia vera L. oleoresin and its antibacterial, anti-virulence and anti-biofilm activities against oral streptococci, including Streptococcus mutans.

Objective: The aim of this study was to characterize the chemical composition of oleoresin of Pistacia vera L. and to determine its antimicrobial and anti-virulence activity versus selected oral streptococci.

Design: A gaschromatografic analysis of the oleoresin was performed.

Attenuation of Virulence by L. Essential Oil.

Anti-virulence strategies are being explored as a novel approach to combat pathogens. Such strategies include inhibition of surface adhesion, tissue invasion, toxin production, and/or interference with the gene regulation of other virulence traits. , the causative agent of listeriosis, is a facultative intracellular food pathogen characterized by a wide distribution in the environment.

Breast milk oligosaccharides: effects of 2'-fucosyllactose and 6'-sialyllactose on the adhesion of and to Caco-2 cells.

It is well known that human milk oligosaccharides play an important role as prebiotics, anti-inflammatory, and anti-infective agents. In the last few years, several studies have been performed using specific oligosaccharides, such as 2'-fucosyllactose and 6'-sialylactose, to evaluate their biological functions. The aim of the present study is to evaluate the anti-adhesive effect of the above oligosaccharides on and .
