Epidemiology of Campylobacter spp. isolated from stool in a tertiary hospital in Cantabria, Northern Spain, from 2016 to 2020 / Epidemiología de Campylobacter spp. aislado de heces en un hospital terciario de Cantabria, norte de España, de 2016 a 2020

Background: The incidence of Campylobacter coli has increased and with greater resistance to antibiotics than Campylobacter jejuni. Objectives: To determine the epidemiology distribution of Campylobacter spp. in our health area, and the sensitivity to commonly tested antibiotics. Methods: Retrospective descriptive study of cases of campylobacteriosis (2016–2020) recovered from stool cultures as laboratory routine protocol. Sensitivity was tested following EUCAST recommendations. Results: Of 1319 campylobacteriosis (C. jejuni 87.7%, C. coli 12.3%) we found a decrease in C. jejuni cases in 2019, and an increase in C. coli. Statistically significant differences were seen in age and gender distribution. The resistance percentages have generally decreased, with higher percentages of resistance in C. coli than in C. jejuni, being significant for erythromycin. Conclusions: There is not an increase of C. jejuni and its resistance but there is a not alarming increase of incidence of C. coli and its resistance in our health area.(AU)

Introducción: La incidencia de Campylobacter coli ha aumentado y con mayor resistencia a los antibióticos que Campylobacter jejuni. Objetivos: Determinar la distribución epidemiológica de Campylobacter spp. en nuestra área de salud y la sensibilidad a los antibióticos comúnmente probados. Métodos: Estudio descriptivo retrospectivo de casos de campilobacteriosis (2016-2020) recuperados de coprocultivos con el protocolo de rutina del laboratorio. La sensibilidad se probó siguiendo las recomendaciones de EUCAST. Resultados: De 1.319 campilobacteriosis (C. jejuni 87,7%, C. coli 12,3%) se encontró una disminución en los casos de C. jejuni en 2019, y un aumento en C. coli. Se observaron diferencias estadísticamente significativas en la distribución de edad y género. Los porcentajes de resistencia han disminuido en general, con porcentajes más altos de resistencia en C. coli que en C. jejuni, siendo significativos para la eritromicina. Conclusiones: No hay un aumento de C. jejuni ni de su resistencia, pero sí un aumento no alarmante de la incidencia de C. coli y su resistencia en nuestra área de salud.(AU)
