Studies on the architecture and on transferability of pathogenicity islands of uropathogenic Escherichia coli strain 536
… and structural characterisation of pathogenicity island V of strain 536 (PAI V536). PAI V536 is integrated at the pheV tRNA gene at 64 minutes of the E. coli K-12 chromosome. In addition to the intact pheV tRNA gene, a truncated copy ('pheV) that represents the last 22 bp of this …

Molecular Mechanisms of Sensing and Synergy by Anti-Bacteriophage Immune Systems in Staphylococcus
… interactions between bacteriophages, S. aureus pathogenicity islands (SaPIs), and CRISPR-Cas systems and detail our discovery that SaPI-mediated parasitism of phages can stimulate the development of CRISPR-Cas adaptive immunity through the production of immunizing defective viral particles. In …

Acquisition and Exclusion of Pathogenicity Island 1 (PAPI-1) in Pseudomonas Aeruginosa
… and adaptation. Conjugative transfer of genomic islands (GIs) has recently been reported in the opportunistic pathogen Pseudomonas aeruginosa. PAPI-1, one of the largest pathogenicity islands of P. aeruginosa, encodes several putative virulence genes and a major regulator of biofilm formation and …

Role of Salmonella enterica subspecies enterica serovar Enteritidis pathogenicity island-2 in chickens
… cause of salmonellosis in humans. Salmonella pathogenicity islands 1 and 2 (SPI-1 and SPI-2) each encode a specialized type III secretion system (T3SS) that enables Salmonella to manipulate host cells at various stages of the invasion/infection process. The SPI-2 T3SS has been identified as …

Resistencia a beta-lactámicos y fluoroquinolonas en Salmonella enterica. Mecanismos moleculares y elementos de movilización génica
… same profile and included the genes located in pathogenicity islands (SPI 1-5), prophage related genes and the virulence plasmid. The fourth objective was to study 11 isolates that showed an extended-spectrum betalactamase (ESBL) or AmpC phenotype. The associated genes were the following ones: …

Untersuchungen zum Einfluß der Pathogenitätsinseln I536 und II536 auf die Genexpression des uropathogenen Escherichia coli Stammes 536
Escherichia coli wird als der häufigste Erreger von Harnwegsinfektionen des Menschen beschrieben. Um die Krankheit auslösen zu können, benötigen die Bakterien ganz bestimmte Eigenschaften, die als Virulenzfaktoren bezeichnet werden und durch die sie sich von apathogenen Stämmen unterscheiden. Der …

Untersuchungen zur Instabilität von Pathogenitätsinseln des uropathogenen Escherichia coli Stammes 536 : "Island Probing" von PAI I(536) - PAI V(536)
Der uropathogene Escherichia coli Stamm 536 (O6:K15:H31) stammt aus einem Patienten mit akuter Pyelonephritis und ist heute einer der Hauptmodellorganismen für Studien zum Vorkommen und zur Funktionalität von Pathogenitätsinseln (PAIs). Sein Genom enthält sechs genetische Elemente (PAI I(536) bis …
