In a previous study, ecs-3, a sequence from avian pathogenic Escherichia coli (APEC) O78:K80 strain chi7122, was found to be expressed in vivo in infected chicken tissues. The region encompassing ecs-3 carries a fimbrial gene cluster that is a putative ortholog of the stg fimbrial gene cluster of Salmonella enterica serovar Typhi. This APEC fimbrial gene cluster, which we have termed stg, is a ...
El Foro de Cooperación Económica Asia Pacífico (APEC): tres décadas trayectoria y escenarios para el futuro. La prosperidad APEC ha sido poca desde inicio siglo continuará así en tanto China Estados Unidos pretendan cohesionar a los países Asia-Pacífico torno su propio proyecto político mediante iniciativas integración económica centradas sobre sus respectivas economías
China implemented strict emission control measures in Beijing and surrounding regions to ensure good air quality during the 2014 Asia-Pacific Economic Cooperation (APEC) summit. We conducted synchronous aerosol particle measurements with two aerosol mass spectrometers at different heights on a meteorological tower in urban Beijing to investigate the variations in particulate composition, source...
Presents information on the APEC 2021 Conference.
Avian pathogenic Escherichia coli (APEC) is a well-recognised pathotype that causes localised and systemic infections in avian species of all ages including eggs. To develop successful intervention strategies, a deep understanding of bacterial and host factors mediating crucial processes in pathogenesis is required. Such information can only be gathered through approaches that embrace infection...
A total factor energy saving target ratio (ESTR) for seventeen APEC economies over 1991-2000 is computed in this paper. All nominal terms are transformed into real terms at the 1995 price level. The data envelopment analysis (DEA) approach is used to find the energy-saving target (EST) for APEC economies without reducing their maximum potential GDPs. Energy, labor, and capital are the three inp...
We investigated the prevalence of plasmid-mediated quinolone resistance (PMQR) genes in avian pathogenic Escherichia coli (APEC) strains in Japan. A total of 117 APEC strains collected between 2004 and 2007 were examined for PMQR genes (qnrA, qnrB, qnrC, qnrD, qnrS, aac(6')-Ib-cr, qepA and oqxAB) by polymerase chain reaction. None of the APEC strains carried qnrA, qnrB, qnrC, qnrD, qnrS, qepA o...
A 43-MDa conjugative plasmid isolated from an avian septicemic Escherichia coli (APEC) strain possessing genes related to the adhesion and invasion capacities of in vitro-cultured cells was sequenced. The results demonstrated that the 43-MDa plasmid harbors bacterial pathogenicity-related sequences which probably allow the wild-type pathogenic strain to adhere to and invade tissues and to cause...
This study aimed to determine the activity of Ketapang extract (Terminalia cattapa L.) in layers infected with APEC. In vitro that was conducted dilution methods using at 5%, 10%, 15%, 20%, 25% and 30% concentrations. vivo by randomly dividing 20 into five treatment groups, four per group. The chickens (except group P0−) were APEC aged 24 weeks. Then, according divided groups one week. said tre...
Colibacillosis accounts for annual multimillion dollar losses in the poultry industry, and control of this disease is hampered by limited understanding of the virulence mechanisms used by avian pathogenic Escherichia coli (APEC). Previous work in our laboratory has found that the presence of the increased serum survival gene (iss) is strongly associated with APEC but not commensal E. coli, maki...
