ABSTRACT
We performed a antibiotic resistance study on Enterococcus faecium isolated from intrahospitalary and extrahospitalary samples between 2004 and 2010. Three different samples were studied; urine, blood and wound swabs, considering a strain per patient. We included in the study a global amount of 637 E. faecium isolares. We employed semiautomatic system WIDER I for identification and sensitivity testing. We considered susceptibility and resistance criteria recommended by MENSURA group. We found a susceptibility rate of 48.05% to betalactams, 100% to linezolid, and 99.46% to vancomycin. The resistance to aminoglycosides ranged between 41.41 and 73.55%. We obtained 6 isolates resistant to vancomycin one of them from an extrahospitalary strain and five from intrahospitalary strains. It seems that vancomycin resistance should be controlled.

Se llevó a cabo un estudio de resistencias a antimicrobianosde los aislamientos de Enterococcus faecalis intrahospitalariosy extrahospitalarios desde enero de 2004 hastaenero de 2008, procedentes de tres tipos de muestras: orinas,exudados y sangre, considerando una sola cepa por paciente.Se incluyeron en el estudio un total de 3.461 aislamientos deEnterococcus faecalis procedentes de muestras clínicas recibidasen el Servicio de Microbiología del Hospital UniversitarioReina Sofía de Córdoba (España). La metodología utilizadafue el método semiautomatizado WIDER I (Soria Melguizo),para la identificación y para el estudio de sensibilidades a antimicrobianos.Se consideraron los criterios de sensibilidad yresistencia recomendados por el grupo MENSURA.Se encontraron unos porcentajes de sensibilidad a betalactámicosdel 98,04%. En aminoglucósidos se obtuvieronlos mayores porcentajes de resistencia entre el 33,82% y48,01%. La sensibilidad a linezolid y a la vancomicina fue del100%.No parece que la incidencia de Enterococcus faecalis resistentea la vancomicina se considere un hecho preocupantehoy en día, pero sí que habría que vigilarlo (AU)

A retrospective survey was carried out on the epidemiological monitoring of the isolation incidence of Mycobacterium marinum in 21 laboratories, in an attempt to gain an insight into the frequency of its isolation in Spain. From 1991 to 1998, 39 cases (22 male and 17 female) of bacteriologically confirmed M. marinum infection were accumulated. The majority of the cases (35) were fish related. The clinical presentation usually suggested sporotrichosis, with the majority of skin eruptions appearing on the hand (32 cases). For treatment, minocycline was recommended as the drug of choice in 12 cases, rifampicin in eight cases and clarithromycin and ethambutol in seven cases.
