الخلاصة

The present study aimed to isolate of Vibrio cholerae which was isolated from the clinical cases of watery diarrhea in Al- Najaf province Teaching Hospital during April 2017 to March 2018. The study included Two main parts. The first one was the bacterial diagnosis of isolated bacteria based on relied and diagnostic procedures. The second part concerned the study of the ability of V.cholerae to resist some chemical and physical factors. This bacteria was suspected for identification by using bacteriological and biochemical tests, after that, it was diagnosed using API 20E. The results revealed the ability of this organism to grow in pH ranged from 4 to 10 but could not grow under or above this range. The optimal pH for growth was 8.5. The results exhibited the ability of this organism to grow in different concentrations of sodium chloride since NaCl was found to stimulate the growth of V.cholerae and optimal concentration was 2.5%, after that the growth became to decline and no growth was found in a concentration of 6%.
