Blood stream infections caused by Acinetobacter ursingii in an obstetrics ward.

The genus Acinetobacter is an important causative pathogen of nosocomial infections in the healthcare setting. The objectives of this study were to determine the species of causative pathogens and the sources of Acinetobacter blood stream infections that occurred in 2 immunocompetent pregnant women admitted to an obstetrics ward within a 2-month period. Phenotypic identification of the two isolates from blood stream infections was inconsistent among the ID test, the MicroScan WalkAway and the Vitek2 systems.
