Clinical Relevance of Type II Fatty Acid Synthesis Bypass in Staphylococcus aureus.

The need for new antimicrobials to treat bacterial infections has led to the use of type II fatty acid synthesis (FASII) enzymes as front-line targets. However, recent studies suggest that FASII inhibitors may not work against the opportunist pathogen , as environmental fatty acids favor emergence of multi-anti-FASII resistance. As fatty acids are abundant in the host and one FASII inhibitor, triclosan, is widespread, we investigated whether fatty acid pools impact resistance in clinical and veterinary isolates.

Transfer between an Algerian and a French hospital of four multi-drug resistant bacterial strains together via a single patient.

A 5 years-old girl, seriously burnt with fire, was first hospitalized during four days in an hospital at Alger, and then transferred to our hospital at Paris. Admitted in our intensive care burns unit, she was third degree burnt on 78% of total body surface area, already treated with imipenem and vancomycin at her arrival. Clinical aggravation was rapidly observed and death occurred within 24 hours.

Escherichia coli virulence patterns may help to predict vesicoureteral reflux in paediatric urinary tract infections.

Aim: Ultrasound and biological tools are used to predict high-grade vesicoureteral reflux, but other markers are needed to better select patients who need voiding cystography. Our aim was to determine whether studying Escherichia coli virulence factors would help to predict vesicoureteral reflux in patients with their first acute pyelonephritis.

Methods: We included children presenting with E.

A novel Pseudomonas aeruginosa bacteriophage, Ab31, a chimera formed from temperate phage PAJU2 and P. putida lytic phage AF: characteristics and mechanism of bacterial resistance.

A novel temperate bacteriophage of Pseudomonas aeruginosa, phage vB_PaeP_Tr60_Ab31 (alias Ab31) is described. Its genome is composed of structural genes related to those of lytic P. putida phage AF, and regulatory genes similar to those of temperate phage PAJU2.
