Abstract: Nocardia is an emerging worldwide distributed zoonotic pathogen,and the common infected population is immu-nocompromised.This article reports a case of non-immunodeficient infected with Nocardia brevicatena/paucivorans complex,combined with literature analysis,aiming to improve scientific reference for clinical diagnosis,treatment and prevention of No-cardia.The patient was a 54-year-old male with no chronic diseases,hospitalized due to repeated low back pain and fever dis-comfort,MRI showed lumbar soft tissue and abdominal abscess.The examination of the immune function aspect was normal,conventional pathogen culture was negative.mNGS showed Nocardia brevicatena/paucivorans complex infection.The anti-in-fection regimen of SMZ was safe and effective,and no recurrence was observed after 1 year of follow-up.Although Nocardia is an opportunistic pathogen,immunocompetent people are still at risk of infection and often present with skin and soft tissue le-sions.
