| Abstract: | Mycoplasma agalactiae and Mycoplasma bovis are closely related species in phylogenetic terms. Pulsed Field Gel Electrophoresis (PFGE) of SmaI, EclXI, Bsi WI, MluI, BssHII, SalI, XhoI, NruI and ApaI digested DNAs were used to analyse and to compare restriction fragment length polymorphism between M. agalactiae and M. bovis and to estimate their genome sizes. SmaI, EclXI and Bsi WI enzymes cleaved DNAs of both microrganisms. MluI, BssHII, SalI, XhoI and NruI digested only M. agalactiae DNA whereas ApaI cut only M. bovis DNA. The total DNA length was established to be 945 +/- 8.4 Kb for M. agalactiae and 961 +/- 18.9 Kb for M. bovis. |
