(1) Schluter A; Heuer H; Szczepanowski R; Poler SM; Schneiker S; Puhler A; Top EM (2005). Plasmid pB8 is closely related to the prototype IncP-1beta plasmid R751 but transfers poorly to Escherichia coli and carries a new transposon encoding a small multidrug resistance efflux protein. Plasmid. 54(2):135-48. [PudMed:16122561]
