Rare case report: Perforation Gallbladder Peritonitis Caused by Enterococcus avium at Prof. Dr. I.G.N.G Ngoerah Hospital

Enterococcus is a gram-positive, catalase-negative, and non-spore-bearing bacteria that generally live in the digestive tract of humans and animals. Enterococcus avium has rarely been detected infecting humans. Enterococcus avium has low virulence and is an opportunistic pathogen in hosts with weakeness immune systems. The most frequently reported sites of entry are the biliary tract and stomach. Peritonitis caused by Enterococcus avium is rare. Infection generally occurs through bacterial colonization. We report the first case of a patient with Gallbladder perforation resulting in peritonitis caused by Enterococcus avium at Prof. dr.I.G.N.G Ngoerah Hospital. Case Presentation: A 67-year-old Balinese man with peritonitis due to gallbladder perforation caused by infection Enterococcus avium. Previously the patient complained of stomach pain, and the patient had a history of gallstone disease. Subsequently, surgery was performed on the patient. During the operation, pus and perforation of the gallbladder were found. The pus specimen was examined in the microbiology laboratory, and the Enterococcus avium bacteria was identified as a significant agent causing the infection. In this case, ampicillin was recommended as therapy. After 5 days of antibiotics, the patient’s condition improved. Conclusion: Enterococcus avium has low virulence and is an opportunistic pathogen in an immunocompromised host. The finding case will be beneficial to clinicians because it provides additional information about the lesser-known Enterococcus avium.
