title: A simplified erythromycin resistance cassette for Treponema denticola mutagenesis.
abstract: The primary selectable marker for the genetic studies of Treponema denticola is a hybrid gene cassette containing both ermF and ermAM (ermB) genes. ErmB functions in Escherichia coli, while ErmF has been assumed to confer resistance in T. denticola. We demonstrate here that ErmB is sufficient for erythromycin selection in T. denticola and that the native ermB promoter drives ErmB expression.
