Phylogenetic relationships of 69 neonatal meningitis Escherichia coli strains isolated worldwide were studied. Restriction fragment length polymorphism of rrn operons (rrn RFLP) in these isolates was compared with that of the 72 strains of the ECOR reference collection. Distributions of K1 antigen, of polymerase chain reaction-detected ibe10 gene, pap, afa,(More)
Over a 12-month period, 43 children in eight different wards of our hospital (Hôpital Robert Debré) were infected or colonized with Klebsiella pneumoniae strains producing extended broad-spectrum beta-lactamases. The epidemiology of the outbreak was studied by a molecular approach including the determination of the beta-lactamase physicochemical parameters(More)
During a systematic survey, maternal carriage of Proteus mirabilis was found over a 25-day period in 18 pregnant women admitted to the delivery ward of our hospital maternity. Five neonates born to these mothers were found to be colonized with P. mirabilis. We report here on the use of DNA fingerprinting by the arbitrarily primed polymerase chain reaction(More)
INTRODUCTION Accumulating evidence suggests that, in critically ill patients, a lower hemoglobin transfusion threshold is safe. However, the optimal hemoglobin level and associated transfusion threshold remain unknown in neurocritically ill patients. METHODS We conducted a systematic review of comparative studies (randomized and nonrandomized) to evaluate(More)
Ribotyping with a nonradioactive probing system was used for the epidemiological evaluation of 15 Serratia marcescens nosocomial strains isolated from the stools of 12 children with no apparent illness in five different hospital wards over a 20-day period. Our results indicate that the occurrence of S. marcescens colonization was the result of the spread of(More)
