Additional Information

The research objectives focus on the areas of Bacterial Taxonomy and Microbiology in Public Health:

- Identification of pathogenic bacteria that are difficult to assign taxonomically
- Description of new species
- Study of bacterial population biology through typing
- Epidemiology of antimicrobial resistance and virulence factors for certain bacterial pathogens in different nosocomial/community settings.

These objectives are addressed from the perspective of polyphasic taxonomy (phenotypic and genotypic taxonomy) through the study of targets for genus/species assignment and phylogenetic analyses. The analysis of the virulome and resistome of certain species is approached from the perspective of complete genome sequencing.

Research on invasive infection by Streptococcus pyogenes and other beta-hemolytic streptococci has been carried out since 1994, through the Surveillance Program of the National Center for Microbiology. The typing of invasive S. pyogenes strains circulating in Spain includes determination of: serotype (emm-type); the genetic profile of streptococcal pyrogenic exotoxins; the antimicrobial resistance phenotype; and the genotypes of epidemiologically related strains and/or outbreaks.
