title: In-vitro and in-vivo activities of sulbactam and YTR830H against Acinetobacter calcoaceticus.
abstract: The antibacterial activities of sulbactam and YTR830H, both beta-lactamase inhibitors, were studied against Acinetobacter calcoaceticus, in vitro and in vivo. In-vitro susceptibility tests showed both to be very active against 80 clinical isolates of A. calcoaceticus. Against an intraperitioneal infection in mice, caused by A. calcoaceticus Ac54, the 50% effective doses of sulbactam and YTR830H were 1.62 and 16.7 mg/kg, respectively. Against A. calcoaceticus S31, a strain resistant to gentamicin, sulbactam and YTR830H were active both in vitro and in vivo.
