background: the virulence of a pathogenic vibrio cholerae is dependent on a discrete set of genetic determinants. in this study, we determined the distribution of virulence determinants among the clinical and environmental isolates of v. cholerae. methods: the antibiotic resistance profiles of the isolates were determined using standard disk diffusion assay. pcr assay was performed to analyze t...

Este estudio tiene dos objetivos: Primero, identificar cuáles son los criterios clave de decisión del Outsourcing de Tecnologías de Información (OTI) en las empresas mexicanas. Segundo, identificar las diferencias que existen entre estos factores en las empresas que ya tienen contratados servicios de OTI y las empresas que no lo tienen. Se aplicó un cuestionario a gerentes y directores de 152 e...

Introduction Nowadays, suicide is a public health problem and a social phenomenon that affects human development. From 1995 to 2002, the state of Sonora showed a 3.8% annual average increase in the occurrence of suicide in productive age population, occupying the national third place with regard to this problem’s growth. During the 1970’s suicide in groups of infants and school children between...

the incidence of virulence factors among 114 enterococcus faecalis and 35 enterococcus faecium strains from different clinical specimens were compared with those isolated from control groups. a few of the isolates expressed two or more of the following traits simultaneously: hemolysin, aggregation substance, gelatinase, dnase, hemagglutinin and antibiotic resistance. the frequencies of hemolysi...

Rooth & Partee (1982) and Rooth (1985) have shown that the English-specific rule-by-rule system of PTQ can be factores out into function application plus two transformations for resolving type mismatch (type lifting and variable binding). Building on these insights, this article proposes a universal system for type-driven translation, by adding two more innovations: local type determination for...

Good frameworks are ussualy the result of many iterations and a lot of hard work involving strucural changes. These iterations make the relationships among classes more explicit and interfaces more abstract. In this way, a framework constitutes an ever-evolving representation in terms of variations and commonalties as consequence of diverse factores relationated with domain changes. However, as...

conclusions: high percentage of hemolysins, biofilm and beta lactamase production by isolated staphylococci, suggests an important role of these virulence factors in the pathogenesis of isolated staphylococci from dermatitis lesions. the s. aureus isolates from wound infections, show a high sensitivity pattern to all examined antibiotics. only ciprofloxacin was found to be active against all is...

background putative virulence factors are responsible for the pathogenicity of utis caused by pseudomonas aeruginosa (p. aeruginosa). resistance of p. aeruginosa to commonly used antibiotics is caused by the extreme overprescription of those antibiotics. objectives the goal of the present study was to investigate the prevalence of virulence factors and the antibiotic resistance patterns of p. a...
