“…Sin embargo, la tendencia mundial de las infecciones por S. sonnei ha cambiado debido a elementos multifactoriales basados en la geografía, el clima, las relaciones huésped-patógeno y las estrategias de control correspondientes. En España hay publicado un caso autóctono, en 2011, correspondiente a S. sonnei [ 37 ]; otros casos por S. sonnei y S. flexneri entre el año 2015 y 2019, y más recientemente un caso de S. flexneri , en nuestro medio, en el año 2020 [ 38 ]. Cabe destacar que en 2016 y 2017 no se detectaron casos de shigelosis en nuestro medio, aunque nuestro laboratorio no ha cambiado los procedimientos de detección de este microorganismo a lo largo del tiempo.…”

“…S. sonnei evolucionó rápidamente desde Europa y se propagó como linaje único resistente a múltiples fármacos (MDR) a otros continentes predominantemente [39]. El número de episodios de enteritis por patógenos multirresistentes están aumentado en nuestro medio [38]. Los aislamientos de Shigella en muchos países han adquirido rasgos de resistencia que conducen a la ineficacia de las cefalosporinas para el tratamiento de algunos pacientes [40][41][42].…”

Introduction. In the bacterial etiology of severe acute infectious diarrhea, except that caused by Clostridioides difficile, most of them have an invasive character and antibiotic treatment will be necessary in specific situations. Shigella is a classic pathogen, in which it is crucial to know the sensitivity to different classic and alternative antimicrobials. The objective of this work was to analyze the presence of shigellosis and the rate of antibiotic resistance. Methods. A descriptive-retrospective study of the reports of shigellosis of stool cultures issued between January 2016 and April 2022 was conducted. Results. A total of 34 episodes (16 -47.1%- by Shigella sonnei) were observed, as of 2018. There were only 2 pediatric cases. The overall resistance rate to azithromycin, trimethoprim-sulfamethoxazole and ciprofloxacin was 52.9%, 64.7% and 44.1%, respectively. 26.5% were resistant to the 3 groups of antibiotics. There was a higher rate of resistance for S. sonnei. The emergence of resistance to cephalosporins in recent years stands out. Episodes of multidrug-resistant shigellosis were detected between 2020 (1 by S. flexneri) and 2022 (4 by S. sonnei). Conclusions. The episodes of shigellosis are emerging in our environment with a higher rate of multi-resistance. In this context, current empirical treatments for acute enteroinvasive enteritis are at risk of failure, if necessary.
