Flowering relies on signaling networks that integrate endogenous and external cues. Normally, plants flower at a particular season, reflecting day length and/or temperature cues. However, plants can surpass this seasonal regulation and show precocious flowering under stress environmental conditions. Here, we show that UV-C light stress activates the(More)
Two strains of Enterobacteriaceae, Escherichia coli and Klebsiella pneumoniae, producing VIM-1 were isolated for the first time in Spain. In both strains, bla(VIM-1) was found to be carried on a gene cassette inserted into a class 1 integron. The bla(VIM-1)-containing integron was located on a transferable plasmid.
The present study was carried out to evaluate the prevalence of the clonal subgroup O16:H5-ST131 and the H30 and H30-Rx subclones among E. coli isolates causing extraintestinal infections and to know their virulence potential. The ST131 clonal group accounted for 490 (16%) of the 2995 isolates obtained from clinical samples in five Spanish hospitals during(More)
The aim of this study was to evaluate the incidence of decreased susceptibility to broad-spectrum cephalosporins in Enterobacteriaceae that lack inducible chromosomal bla genes, and to determine the enzymes responsible for resistance. From all clinically relevant Enterobacteriaceae strains isolated between 1994 and 1996, 88 of 7054 Escherichia coli, seven(More)
Phage typing and DNA macrorestriction fragment analysis by pulsed-field electrophoresis (PFGE) were used for the epidemiological subtyping of a collection of Shiga toxin-producing Escherichia coli (STEC) O157:H7 strains isolated in Spain between 1980 and 1999. Phage typing distinguished a total of 18 phage types among 171 strains isolated from different(More)
BACKGROUND The mechanisms of resistance to fluoroquinolones and beta-lactams were studied in isolates of Salmonella enterica resistant to both antimicrobial groups, isolated over time from two patients treated with fluoroquinolones. METHODS The clonal relationships among the various strains was established by serotyping and pulsed-field gel(More)
This work focuses on the Service Entities definition as an approach that may help to support structural and functional Collaborative Networked Organizations (CNO) modeling, when VOs are engineered inside Virtual Breeding Environments Management Systems (VMS). Manbree is an undergoing development which is intended to provide an integrated framework for CNO(More)
resistance rates of Salmonella enterica strains isolated from children of two Southern European countries. The study included 9527 (2096 Italian and 7431 Spanish) children (median age: 3.0 years; range: 7 days to 19.2 years) admitted for acute diarrhoea to the Department of Paediatrics, University of Florence, Italy, and the Hospital Valle d’Hebron,(More)
