En el Laboratorio de I.R.A.S., también denominado de "Infecciones Intrahospitalarias", nos centramos actualmente en la caracterización molecular de los estafilococos, tanto S. aureus, como coagulasa negativos.
Los marcadores moleculares habituales, en el caso de los S. aureus son: electroforesis en campo pulsado (PFGE), tipificación multilocus de secuencias (MLST), tipo de casete cromosómico estafilocócico (SSCmec), tipificación spa, También detectamos, entre otros, los genes mec y PVL, los genes que codifican la Toxina exfoliativa (SST) y la Toxina del Shock Tóxico. Asimismo, para la identificación de los estafilococos coagulasa negativos, secuenciamos los genes 16S, rpoB, tuf., a los que también aplicamos PFGE, SSCmec, MLST.
Nuestras líneas de investigación se centran, por un lado, en el estudio de los mecanismos de resistencia a las oxazolidinonas: gen cfr, dominio del gen 23S ARNr , gen rplC (riboproteína L3), gen rplD (riboproteína L4), gen rplV (riboproteína L22). Hemos detectado, por primera vez, la existencia de nuevas mutaciones en la riboproteína L4 en un paciente con fibrosis quística. Aparte de los estudios llevados a cabo de las resistencias al linezolid en distintos hospitales, estudiamos en colaboración con la Universidad de Tsukuba (Japón) y la Universidad Europea la prevalencia del plásmido pSCFS7 entre cepas cfr positivas de distintos hospitales españoles.
Por otra parte, participamos en estudios multicéntricos (2002-2014) para conocer mejor el estado de la población estafilocócica española, centrándonos fundamentalmente en las cepas de S. aureus resistentes a meticilina (SARM); dado que es un importante patógeno humano que causa una amplia variedad de infecciones que pueden ser leves, como algunas infecciones de piel y partes blandas, o graves, como bacteriemia, endocarditis, neumonía e infecciones de localización quirúrgica. Además, pueden producir una colonización asintomática, lo que facilita su transmisión y diseminación. Desde su descripción inicial en 1959 y durante varias décadas, el SARM se había considerado un patógeno confinado al ámbito sanitario, pero a partir de la década de los noventa, se describe la emergencia de cepas SARM responsables de infecciones aparentemente adquiridas en la comunidad.
Dentro de esta línea estamos colaborando en el proyecto: "Colonización por S. aureus resistente a la meticilina en niños sanos de la comunidad (estudio C.O.S.A.C.O.)", que es un estudio multicéntrico de ámbito nacional.
También colaboramos con otros laboratorios en distintos estudios, como: "Mecanismos de patogenicidad y protección en bacterias Gram positivas causantes de enfermedades respiratorias y bacteriemia".
