Epidemiología clínica y molecular de las infecciones por Shigella spp en niños de la Región Metropolitana durante el verano 2004-2005

During summer 2004-2005, stoolsamples from children with diarrhea were collected in Cary Blair transport medium and cultured.Shigella isolates were serotyped using monoclonal and polyclonal commercial antibodies. In vitroactivity of ampicillin, amoxicillin/clavulanic acid, chloramphenicol, cotrimoxazol, nalidixic acid,ciprofloxacin, ceftriaxone and azythromycin was determined by minimal inhibitory concentration(MIC). Clonality was studied by pulsed-field gel electrophoresis (PFGE) using XbaI as restrictionenzyme.
