Claim:
A method for inhibiting growth of Mycobacterium avium subsp. paratuberculosis , comprising applying a caprazamycin derivative represented by one of the following general formula (II), (III), (V), (VI) or (VII) to Mycobacterium avium subsp. paratuberculosis : wherein Me is a methyl group; and R 1 is a straight or substantially straight chain alkyl group having 5 to 21 carbon atoms, a straight or substantially straight chain alkenyl group having 5 to 21 carbon atoms, a cycloalkyl group having 5 to 12 carbon atoms, or a phenyl group substituted at the para-position with a straight chain alkyl group having 1 to 14 carbon atoms, a straight chain alkoxy group having 1 to 9 carbon atoms or a cycloalkyl group having 5 to 12 carbon atoms; wherein Me is a methyl group; and R 2 is a straight or substantially straight chain alkyl group having 5 to 21 carbon atoms, a straight or substantially straight chain alkenyl group having 5 to 21 carbon atoms, or an alkynyl group having 5 to 21 carbon atoms; wherein Me is a methyl group; and R 3 is a straight or substantially straight chain alkyl group having 5 to 21 carbon atoms, a straight or substantially straight chain alkenyl group having 5 to 21 carbon atoms, or a cycloalkyl group having 5 to 12 carbon atoms; wherein Me is a methyl group; R 3 is a straight or substantially straight chain alkyl group having 5 to 21 carbon atoms, a straight or substantially straight chain alkenyl group having 5 to 21 carbon atoms, or a cycloalkyl group having 5 to 12 carbon atoms; and R 4 is a straight or substantially straight chain alkyl group having 5 to 21 carbon atoms, a straight or substantially straight chain alkenyl group having 5 to 21 carbon atoms, or an alkynyl group having 5 to 21 carbon atoms; and wherein Me is a methyl group; R 4 is a straight or substantially straight chain alkyl group having 5 to 21 carbon atoms, a straight or substantially straight chain alkenyl group having 5 to 21 carbon atoms, or an alkynyl group having 5 to 21 carbon atoms; and R 5 is a hydrogen atom, or a straight or substantially straight chain alkyl group having 1 to 21 carbon atoms.
