Molecular Properties of Virulence and Antibiotic Resistance of Causing Clinically Critical Infections.

The increase in the number of hospital strains of hypervirulent and multidrug resistant (MDR) is a major health problem that reduces medical treatment options and increases mortality. The molecular profiles of virulence and multidrug resistance of -associated hospital and community infections in Mexico have been poorly studied. In this study, we analyzed the different molecular profiles associated with the virulence genotypes related to multidrug resistance and the genotypes of multidrug efflux pumps () in causing clinically critical infections isolated from Mexican patients with community- and hospital-acquired infections.

Analysis of expression of virulence genes related to antibiotic and disinfectant resistance in as an emerging periodontal pathogen.

The collective involvement of virulence markers of as an emerging pathogen associated with periodontitis remains unexplained. This study aimed to implement an model of infection using a human epithelial cell line to determine the virulome expression related to the antibiotic and disinfectant resistance genotype and pulse field gel electrophoresis (PFGE) type in strains isolated from patients with periodontal diseases. We studied 100 strains of isolated from patients with gingivitis (n = 12), moderate periodontitis (n = 59), and chronic periodontitis (n = 29).
