title: Deep neck abscess due to Acinetobacter baumannii infection.
abstract: Acinetobacter baumannii strains are isolated in up to 1% of nosocomial infections mostly from intensive care units immunocompromised patients and are associated with high mortality rates. A baumannii infections include pneumonia, urinary tract infection, endocarditis, skin and soft-tissue infections, surgical-site infection, meningitis, osteomyelitis, and septicemia. We report an extremely rare case of deep neck abscess due to multidrug-resistant A baumannii infection. The isolate strain was analyzed by a repetitive sequence-based polymerase chain reaction typing method: the isolate profile was compared with other strains obtained from isolates recovered in the hospital in that period. Our patient underwent 2 neck explorations and antibiotic treatment (tigecycline 50 mg, twice per day). Five weeks after admission, the patient was discharged in good general conditions. Considering the other obtained strains, 4 different profiles were identified, one as prominent (profile A, 18 isolates), the index case (B), and 2 others (C, D) as divergent.
