Introduction. Multidrug-resistant Salmonella Infantis have been isolated in Ecuador, Peru and Bolivia in the recent past years. Objectives. To evaluate the emergence and burden of Salmonella Infantis infection in a public hospital of Lima, Peru. Methods. We prospectively followed consecutive cases of salmonellosis at Cayetano Heredia hospital (October 2015-May 2017). Detection of invA gene by PCR and determination of serovars by a multiplex PCR were performed. Antimicrobial susceptibility was assessed by disk diffusion method. Detection of extended-spectrum β-lactamase phenotype was done by double disc method. Results. Seventy isolates from 50 patients were confirmed as Salmonella. Only one isolate per patient was further analyzed. The most frequent serovar detected was Infantis (n = 18; 36%), followed by Typhimurium and Enteritidis (n = 13, 26%, each). In thirty cases Salmonella was is...

El hemocultivo es el ‘gold standard’ para el diagnóstico de bacteremias, las cuales se asocian a una alta mortalidad si no son tratadas tempranamente. Es crítico monitorizar el rendimiento y calidad de esta herramienta diagnóstica a través de los indicadores recomendados por el Instituto de Normas Clínicas y de Laboratorio: Tasa de positividad: 6% a 12% y tasa de contaminación: ≤ 3%.El objetivo del estudio fue evaluar el rendimiento y calidad de hemocultivos realizados en hospitales públicos del Perú. Metodología: Estudio transversal que incluyó a laboratorios de microbiología de hospitales de nivel II-2 y III, de diversas regiones del Perú, entre julio 2017-julio 2019. Se recolectó información mensual de todos los hemocultivos procesados, incluyendo número total de pacientes muestreados, botellas procesadas, hemocultivos positivos y aislamientos de Staphylococcus co...

Worldwide, Candida bloodstream infections have presented an increase in non-albicans Candida species and resistance to antifungal agents. Objective: To describe the microbiological characteristics of consecutive Candida blood culture isolates. Methods: This study analyzed 73 consecutive Candida blood isolates recovered between July 2017 and July 2019 from routine patient care at 15 Peruvian hospitals, assessing susceptibility to four antifungal agents. Results: The species most frequently detected were Candida parapsilosis 39 (53.4%), Candida albicans 23 (31.5%), and Candida tropicalis 5 (6.8%). Conclusions: All isolates were susceptible to amphotericin B, fluconazole, voriconazole, and anidulafungin. There is a predominance of non-albicans Candida cases in Peru and a high susceptibility to current antifungal drugs.
