The phenogenetic and phylogenetic relationships among 7 identified strains of C.
pseudotuberculosis isolated from sheep were checked by PCR specific primers demonstrated with random amplified polymorphic DNA – polymerase chain reaction (RAPD – PCR) by using five arbitrarily primers. C pseudotuberculosis isolates were distinguished according to the banding patterns of their amplified DNA on agarose gel. The variation can be used for diagnostic differentiation among C.  pseudotuberculosis strains. Differences were observed in RAPD patterns between the 7 isolates and this may be due to the presence of novel serovars of this microorganism.
