Tem and CTX-M extended-spectrum beta-lactamase in Klebsiella spp and Escherichia coli isolates from inanimate surfaces of hospital environments. Cajamarca, Peru. Lambayeque, Peru. The aim of the study was to determine the genotype of 15 ESBL strains of Enterobacteriaceae resistant to beta-lactams, isolated from inanimate surfaces and phenotypically characterized as producing extended-spectrum beta-lactamase. Eleven strains presented both fragments at the time and only three had blaCTX-M.

Antecedentes: La gangrena de Fournier GF es una fascitis necrotizante que pone en peligro la vida del paciente. Los valores cualitativos medidos se expresaron como frecuencia y porcentaje, y se compararon con la prueba de ji al cuadrado y la prueba de Fisher. Resultados: Los pacientes que murieron presentaban con mayor frecuencia cultivos de orina y herida positivos para Escherichia coli productora de betalactamasas de espectro extendido BLEE : orina, sobrevivientes The objective of this study was to determine the etiology and impact of the agent isolated on wound and urine culture. Method: We performed a retrospective analysis within a cohort of 66 patients with FG of urogenital origin. Results: Patients who died had more frequent cultures of urine and wound positive for extended-spectrum beta-lactamase ESBL -producing Escherichia coli: urine, survivors Conclusions: During the integral evaluation of the patient with FG it is essential to perform the urine and surgical wound cultures in order to initiate the antibiotic management directed at an early stage.
