The Laboratory of Medical Entomology (LME) develops an intense reference and research activity, focused on the field of disease vectors of interest in Public Health. The LME has an insectary where biological cycles of insect vectors are currently maintained, allowing the performance, among others, of vector competence and xenodiagnostic studies. The LME supports the national health system by offering techniques available in the portfolio of services for the taxonomic identification of arthropods of health interest. In addition, it performs entomological surveillance of outbreaks, supporting Surveillance Plans. In particular, the LME plays a leading role in the Entomological Surveillance Plan for Leishmaniasis in the Community of Madrid. On the other hand, the LME offers scientific advice to the CCAES (Centro de Coordinación de Alertas y Emergencias Sanitarias, Ministerio de Sanidad, Consumo y Bienestar Social), and participates in the elaboration of reports and rapid risk assessments.
The main research lines of the Laboratory of Medical Entomology are:
1. Maintenance of insect vector colonies: phlebotomine sand flies (Phlebotomus perniciosus, Phlebotomus papatasi and Phlebotomus argentipes, vectors of Leishmania infantum, Leishmania major and Leishmania donovani, respectively), Culex and Aedes mosquitoes (vectors of various arboviruses) and Rhodnius prolixus (vector of Trypanosoma cruzi).
2. Biology of disease vectors of public health interest: biology, vector competence, experimental infections. The CNM has a BSL3 safety laboratory to carry out vector competence studies with culicidae and phlebotomine sand flies.
3. Entomological sampling, infectivity of potential reservoirs of leishmaniasis.
4. Insecticides and repellents: evaluation of their efficacy.
5. Characterization of saliva proteins of hematophagous Diptera: genomics, proteomics, biochemistry and gene editing. Study of salivary proteins as markers of bite exposure, virulence factors and/or vaccines.
6. Xenodiagnosis of leishmaniasis.
7. Molecular biology and taxonomy of phlebotomine sand flies. Molecular detection of Leishmania infantum in phlebotomine sand flies and characterization of Leishmania spp. Molecular identification of blood ingested by vectors.

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.

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.
