Introduction:  Serratia ficaria, is a Gram-negative rod first identified in 1979 in the fig tree ecosystem. Since then, Serratia ficaria has been occasionally isolated from human specimens. According to literature, Serratia ficaria is an opportunistic pathogen that rarely affects human, when infection occurs it can lead to different clinical conditions, including gallbladder empyema, lithiasis, ophthalmitis, leg ulceration, respiratory infections.Case presentation: We report the case of a 66-year-old woman in whom Serratia ficaria was the causative agent of acute obstructive jaundice. The woman was treated empirically with ceftriaxone and metronidazole before sphincterotomy. Serratia ficaria was isolated from bile samples collected by Endoscopic Retrograde Cholangiopancreatography (ERCP).Conclusion: Serratia ficaria causes mild infections in most cases, however, severe infections such as soft tissue infections or septicemia are reported in the literature. In this case, ERCP was crucial in the diagnosis and treatment of the patient, which favorably resolved the infection.
