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.

Inés Martín Martín
Tenured Scientist
ORCID code: 0000-0002-0956-7324
Within Medical Entomology, my work focuses on the study of phlebotomine sand flies and culicidae as vectors of leishmaniasis and arbovirosis, respectively. In 2014 I obtained my PhD degree “cum laude” with European mention from the Complutense University of Madrid. My PhD Thesis (developed at the Instituto de Salud Carlos III), focused on the study of phlebotomine sandfly saliva. Subsequently, during my postdoctoral period, I worked on insect gene editing, molecular, biochemical and functional characterization of insect saliva proteins and their role in the infection and transmission of pathogens. Most of my scientific career has been developed at the Laboratory of Malaria and Vector Research, National Institutes of Health (NIH), USA. Since 2021 I am a Senior Scientist at the Laboratory of Medical Entomology (ISCIII).

Ricardo Molina Moreno
Doctor Ad Honorem
ORCID code: 0000-0001-6662-173X
Doctor in Biological Sciences from the Complutense University of Madrid (1994). In 1979 he began his professional career at the Instituto de Salud Carlos III (ISCIII), where he became a researcher in 1985. He was in charge of the Medical Entomology Laboratory from that year until his retirement in 2023. He is currently a doctor linked “Ad Honorem”. He has extensive experience in medical entomology, advising the Ministry of Health (CCAES) and Health Departments of Autonomous Communities, on surveillance and control of arthropods transmitting vector-borne diseases. In recent years he has been involved in surveillance programs in Spain for leishmaniasis vectors, especially in the Fuenlabrada outbreak, and for viruses causing Crimean-Congo hemorrhagic fever and dengue. Also in the surveillance of invasive exotic mosquitoes, especially Aedes albopictus, in ports and airports. In his last stage he has been part of the research group within the CIBER (CIBERINFEC; CB21/13/00110).

Clinical and Biomedical Laboratory Technician
ORCID code: 0000-0002-6553-9969
Graduated in 2019 from the Advanced Vocational Training Program in Clinical and Biomedical Laboratory Sciences. I began my professional career in 2020 at Eurofins Megalab laboratories. In 2024, I started working as a freelance professional on an international project focused on the bioecology of phlebotomine sand flies in urban environments across the Mediterranean Basin, conducting fieldwork in Spain, Italy, Greece, and southern France within the framework of citizen science. Since 2025, I have been part of the Medical Entomology Laboratory at the Instituto de Salud Carlos III (ISCIII), where I work as a laboratory technician on the project “Biochemical and functional characterization of salivary proteins from Phlebotomus perniciosus and their role in Leishmania infantum infection (PERNIPROT)”, led by Dr. Inés Martín Martín.

Additional Information
Streptococcus pneumoniae is a human pathogen that, despite the development of vaccines, continues to be an important cause of mortality and morbidity. We investigate the mechanisms of antibiotic resistance in this bacterium. On the one hand by identifying new therapeutic targets and on the other hand by investigating the molecular basis of the action of antibiotics already used in clinical practice (the fluoroquinolones levofloxacin and moxifloxacin) or not yet used (seconeolitsine). For this purpose, we used a multidisciplinary analysis involving genomics, transcriptomics and proteomics to understand the organization of the S. pneumoniae chromosome and the identification of the factors that stabilize this organization, including ncRNAs. Changes in the level of global supercoiling, either by inhibition of gyrase (decrease) or by inhibition of topoisomerase I (increase) alter the transcriptome. The modulated genes are located in domains, whose genes show specific functional characteristics. The aim is to identify new factors essential for S. pneumoniae physiology and to characterize transcriptional regulation in response to topological stress. In addition, RNA interference technology and CRISPR systems will be used as novel antibacterials. These studies will establish the bases for translational research aimed at the development of new therapeutic targets for the treatment of pneumococcal diseases.
