Abstract
Acinetobacter baumannii is an opportunistic bacterial pathogen associated with health care-associated infections. Neonatal liver abscess is extremely rare. It has a high mortality rate due to difficulties in diagnosis and treatment. Hematogenous dissemination of infection, umbilical venous catheterization, abdominal surgery, sepsis, and immunodeficiencies have been accepted as potential risk factors. In many cases, gram-positive bacteria, particularly Staphylococcus aureus, and gram-negative bacteria, specifically Escherichia coli, are the main pathogens. In the present newborn case, Acinetobacter baumannii was isolated as the causative microorganism from liver abscess culture, blood culture, and subcutaneous abscess culture. To our knowledge, neonatal pyogenic liver abscess due to Acinetobacter baumannii has not been previously reported in the literature.
