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.

Research Scientist
ORCID code: 0000-0002-7114-6686
Degree in Veterinary Medicine in 1995 and PhD in Veterinary Medicine in 2002 from the University of Zaragoza. He did his PhD thesis at NEIKER Tecknalia (Derio, Vizcaya) and the National Center for Microbiology of Instituto de Salud Carlos III (CNM-ISCIII, Majadahonda, Madrid) on the biological cycle of Lyme disease in the Basque Country. After that, he developed his postdoctoral training in different aspects of the pathogenesis of tularemia at the Center for Infectious Diseases, Stony Brook University, New York (USA) for 3 years. In December 2005, he joined the Reference and Research Laboratory in Special Pathogens of the CNM-ISCIII where he developed diagnostic, reference and research activities, in Bartonella, Leptospira and pathogens of interest in bioterrorism. Between 2014-2016 he participated in the European Program for the Training of Microbiologists in Public Health (EUPHEM), organized by the European Centre for Disease Prevention and Control. During this program, he participated in an international mission for the investigation of a cholera outbreak in Ghana, proposed by the Bernhard Nocht Institute for Tropical Diseases in Hamburg (Germany). In December 2016, he worked as a laboratory consultant for the World Health Organization at their office in Phnom Penh (Cambodia). Subsequently, he worked one year with Médecins Sans Frontières as director and quality manager of the TB laboratory in Nukus (Uzbekistan).
In 2019, he joined the HIV Variability and Biology Unit at CNM-ISCIII, where he developed different reference and research activities, including his contribution to the molecular epidemiological surveillance of HIV-1 in Spain and the study of HIV-1 antiretroviral resistance. Since September 2022 he has been leading the Human Papillomavirus Unit at the CNM-ISCIII. -

Additional Information
The research activity of the Viral Biology group since its beginnings in the 1980s has focused on respiratory viruses, especially on the study of the mechanisms of virus entry into the cell, evolutionary aspects, antigenic properties and vaccine development.
Currently, the group's objectives are focused on the characterisation of the immune response and the development of vaccines against human pneumoviruses: human respiratory syncytial virus (hRSV) and human metapneumovirus (hMPV).
Both viruses are considered to be important respiratory pathogens of high clinical relevance, especially in the paediatric population.
Safe and effective vaccines against these viruses are currently not available. Soluble protein subunits based on the fusion protein (F-protein) of hRSV and hMPV are being developed in the laboratory by protein engineering for use as vaccines against human pneumoviruses.
On the other hand, and thanks to the characterisation of the type of humoral response induced by the F proteins of these viruses, the laboratory is also involved in the isolation of monoclonal antibodies and nanoantibodies for use as treatments against these viruses.
