Virulence genes in Moraxella spp. isolates from infectious bovine keratoconjunctivitis cases
Introduction: Infectious bovine keratoconjunctivitis (IBK) is an important ocular disease which affects cattle worldwide. To advance towards IBK effective prevention and treatment strategies, it is important to define the distribution and genetic ...

Sequential Mechanism of Assembly of Multidrug Efflux Pump AcrAB-TolC
Multidrug efflux pumps adversely affect both the clinical effectiveness of existing antibiotics and the discovery process to find new ones. In this study, we reconstituted and characterized by surface plasmon resonance the assembly of AcrAB-TolC, the archetypal multidrug efflux pump from Escherichia coli.
