Abstract

Shigellosis is an acute, often dysenteric, diarrhoeal illness that is responsible for much morbidity and mortality worldwide. Increasing rates of multidrug-resistant (MDR) and extensively drug-resistant (XDR) Shigella species have been detected worldwide and a regular review of local epidemiological and resistance rates is necessary to help guide empirical antibiotic choice. This retrospective laboratory study of faecal isolates between 2013 and 2023 demonstrates increasing rates of resistance to third-generation cephalosporins, azithromycin and ciprofloxacin, alongside an overall increase in MDR and XDR isolates.
