  • Title: ISMmy1, a novel insertion sequence of Mycoplasma mycoides subsp. mycoides small colony type.
    Author: Westberg J, Persson A, Pettersson B, Uhlén M, Johansson KE.
    Journal: FEMS Microbiol Lett; 2002 Mar 05; 208(2):207-13. PubMed ID: 11959438.
    Abstract:
    A new insertion sequence, ISMmy1, has been identified in the bovine pathogen Mycoplasma mycoides subsp. mycoides biotype small colony (MmymySC). The occurrence of ISMmy1 in 15 MmymySC strains and 12 other mycoplasmas was examined by Southern blotting. All MmymySC strains showed identical hybridisation patterns except for the type strain PG1(T), the vaccine strain T1Sr49, and the strain Afadé, which all had unique patterns. ISMmy1-like sequences were also found in the bovine pathogen Mycoplasma bovis strain Donetta(T) while mycoplasmas that are phylogenetically closer to MmymySC lack ISMmy1. This observation suggests horizontal transfer between MmymySC and M. bovis.
