title: Molecular identification and epidemiology of animal mycoplasmas.
abstract: Molecular genetic techniques show a high potential for rapid and accurate identification of Mycoplasma species isolated from animals. An important field of application for such methods is the differentiation of species and/or subspecies which are phenotypically closely related, but which show significant differences in epidemiological impact. This need is particularly important for the mycoplasmas of the "mycoides group", which are phenotypically and phylogenetically very closely related. Molecular typing techniques based on 16S rRNA genes give straightforward phylogenetic answers on the species level. For more refined methods of subtyping at the subspecies level, the use of defined genes characteristic of certain Mycoplasma species or clusters is recommended. Genetic fingerprinting, especially insertion sequence typing has proved to be a valuable tool for subtyping and strain identification in particular of vaccine strains and for epidemiological investigations.
