This work reports the utilization of an in vivo expression technology system to identify in vivo-induced (ivi) genes in Yersinia ruckeri after determination of the conditions needed for its selection in fish. Fourteen clones were selected, and the cloned DNA fragments were analyzed after partial sequencing. In addition to sequences with no significant(More)
A multiplex PCR assay based on the 16S rRNA genes was developed for the simultaneous detection of three major fish pathogens, Aeromonas salmonicida, Flavobacterium psychrophilum, and Yersinia ruckeri. The assay proved to be specific and as sensitive as each single PCR assay, with detection limits in the range of 6, 0.6, and 27 CFU for A. salmonicida, F.(More)
Yersinia ruckeri is a Gram-negative pathogen that causes enteric redmouth disease in salmonids. A gene from Y. ruckeri encoding an extracellular protease termed yrp1 (Yersinia ruckeri protease 1) was cloned from a Sau3AI library constructed in pUC19 and analysed in gelatin-supplemented medium. The nucleotide sequence of the yrp1 gene indicated an ORF(More)
BACKGROUND Complicated pyelonephritis (cPN), a common cause of hospital admission, is still a poorly-understood entity given the difficulty involved in its correct definition. The aim of this study was to analyze the main epidemiological, clinical, and microbiological characteristics of cPN and its prognosis in a large cohort of patients with cPN. METHODS(More)
A current concern of modern societies is the quality of their educational systems. Learning Management Systems (LMSs) are technological tools that have been used to improve and extend the traditional educational system. Although LMSs have greatly benefited from technological advances, this type of educational platforms are still in need of mechanisms to(More)
