The morphological characteristics of the isolates were very variable to each other. The isoenzymes profiles revealed polymorphic bands or the data were subjected to analysis with the JMP method. The isolates were grouped into 2 main groups A and B, those last were divided into sub-groups. Nineteen (19) isolates creates the group A and four isolates (E1, E2, E3 and M15A) formed the group B. analysis of isozyme banding patterns were found to be a reliable marker technology, efficient and effective tools to find the genetic variability among isolates isolated in different geographical areas.enArticle
