Acinetobacter baumannii in Southern Croatia: clonal lineages, biofilm formation, and resistance patterns.

Background: Acinetobacter baumannii is one of the most prevalent causes of severe hospital-acquired infections and is responsible for the dramatic increase in carbapenem resistance in Croatia in the last 5 years. Such data have encouraged multicenter research focused on the organism's ability to form biofilm, susceptibility to antibiotics, and particular genotype lineage.

Methods: Biofilm formation in 109 unrelated clinical isolates of A.
