Zahid S.Aziz,Abbas Sh. Al- Muhanna,Abbas J. Salman and Maytham Abbas Alzuhairi

In the present study 800 clinical samples were collected and subjected to biotypes studies. Whereas the present study proved candidates isolates revealed many of biotypes belong the same species of Klebsiella and Raoultella. Furthermore, this study also demonstrated that isolates which had been candidates to Vitek-2 system,revealed different probabilities,the probability of identification were as follow , excellent 54.7%, very good 7.5%, good 24.5%, acceptable13.2% and low discrimination 1.88% and sum of (excellent ,very good and good ) was 86.7%. Also there was high degree of coalition to the level of species and subspecies. In this study we suggested that Vitek 2 system is the best methods to detect biotyping of pathogenic microorganism before studying phylogenetic analysis of microorganisms.
