El año 2017 la Organización Mundial de la Salud publicó una lista de bacterias con alta resistencia a antimicrobianos. En la lista, se incluye al Campylobacter como un patógeno de alta prioridad debido a su progresiva, alarmante y alta resistencia a fluoroquinolonas a nivel global. Con la finalidad de determinar la sensibilidad antimicrobiana de Campylobacter aislados en pacientes pediátricos de un hospital de la ciudad de Lima, se realizó un estudio en el área de microbiología del Departamento de Ayuda al Diagnóstico del Hospital Nacional Docente Madre Niño San Bartolomé, en dos periodos comprendidos entre noviembre de 2012 a febrero de 2013, y diciembre de 2014 a julio de 2015.

Objective: To evaluate the diagnostic performance of blood agar with filter (BSA) in comparison with Karmali agar (AK) for the diagnosis of Campylobacter spp in stool culture. Material and methods: A cross-sectional prospective experimental research was carried out at the Hospital Nacional Docente Madre-Niño "San Bartolomé", where stool samples with functional stool examination reactive for inflammation were evaluated. The samples were seeded in ASF and AK and incubated up to 72 hours in microaerophilia. Species differentiation was performed with hippurate hydrolysis. Results: A total of 287 positive samples were collected. The isolation of Campylobacter in ASF and AK was 78.3% and 21.7%, respectively. Sensitivity was 90.9% for ASF. Mean growth time was 32.7 ± 11 hours (p<0.59) and contamination of culture media from positive patients was 61.7% for AK. 74.8% of non-jejuni Campyloba...
