The aim of this study was to determine whether the high levels of erythromycin resistance in Streptococcus pyogenes found in Spain are due to the introduction and spread of one or more clones. Phenotypic and genotypic techniques were used to characterize all erythromycin-resistant S. pyogenes (ErR) isolated in Gipuzkoa, Spain, in the last 10 years and 128(More)
We performed limited autopsy with histological examination of tissue cores obtained percutaneously using the Tru-Cut needle and the Jamshidi trocar in 150 adult HIV-positive patients. Data were compared retrospectively with the antemortem clinical diagnosis. Eighty-one percent of the patients were male, and 78% were intravenous drug users. Specimens were(More)
We describe an 84-year-old woman who developed remitting seronegative symmetrical synovitis with pitting edema (RS3PE) associated with a subcutaneous abscess of the hand due to Streptobacillus moniliformis. Polyarthritis and edema were relieved after therapy with corticosteroids. We review the association of RS3PE to different rheumatologic, neoplastic, or(More)
A linezolid-resistant, methicillin-susceptible isolate of Staphylococcus aureus was obtained from an infected surgical wound in an ambulatory patient. The isolate belonged to ST125 and was susceptible to all the antibiotics tested except linezolid (MIC 8 μg/ml) and levofloxacin. Linezolid resistance could be ascribed to the presence of the mutation G2576T(More)
The mechanisms of linezolid resistance among 86 staphylococcal isolates from two intensive care units were investigated. The most frequent was the G2576T mutation in the 23S rRNA (82%). The cfr gene was found in 17% of the isolates, seven S. aureus and eight S. epidermidis isolates. Four of the S. epidermidis isolates had the G2576T mutation and the cfr(More)
We report a case of an immunocompetent woman with atypical marginal keratitis. She presented with recurrent episodes of multiples microabscess distributed in a triangular pattern associated with stromal oedema and anterior chamber uveitis, affecting both eyes, but not simultaneously. The episodes responded to steroid drops, corneal inflammation was(More)
A disposable PCR-based amperometric magneto-genosensor for detection and identification of Streptococcus pneumoniae was evaluated. ROC curve analysis used to determine optimal signal cutoff values yielded a sensitivity of 91% and a specificity of 90%. The method was also tested for the direct detection of pneumococci in clinical samples.
