Tularaemia is a zoonotic disease caused by Francisella tularensis (F. tularensis). Human infection is rare and can be life-threatening. F. tularensis subsp. novicida used to be a subspecies of F. tularensis, is now considered a different species, F. novicida. Though less virulent, F. novicida can cause morbidity and mortality among debilitated or immunocompromised patients. We reported that an adult with end-stage renal disease undergoing haemodialysis and a history of melioidotic aortic aneurysm developed F. novicida bacteraemic pneumonia, which was uneventfully treated by antimicrobial therapy. The microbiological confirmation of F. novicida infection relies on 16S rRNA sequencing. It is the first case of F. novicida infection in Taiwan.
