Abstract
Gastro-enteritis due to Vibrio Cholera was increased suddenly in summer of 1998 in our country. In this research we studied epidemiological and clinical features of Cholerae patients. Vibrio Cholera isolated from 189 (3.3%) patients from 56II stool samples. 182 (96.2%) Vibrio Cholera O1 isolated. 46 (24%) patients with positive stool cultures for Vibrio Cholera were hospitalized. 50% patients were 15-45 yrs. No sex predominency was seen. The important observations in this study including: Fever in 28.1% (13) of patients, sever leukocytosis in 15% (7) of patients, RBC in stool in 33% (15) of patients. Fever and neutrophilia and RBC in stool probably shows co-infection with order intestinal pathogens or different serotypes of Vibrio Cholera with new characteristics. So we are recommending extensive research to be done on serotyping of all of the isolates of Vibrio cholera and other intestinal pathogens simultaneously.

Abstract
Background&Objective: Vibrio species are oxidase positive, gram negative bacilli that predominantly reside in surface waters such as lakes , rivers. They cause predominantly intestinal diseases as well as a few extra-intestinal complications. Vibrio-related diseases often rise during natural disasters such as floods. Vibrio cholerae cause cholera in humans. In this study, the occurance of Vibrio cholerae in the surface waters of Golestan province, was investigated. Materials&Methods: The APW and TCBS agar culture media were used for primary isolation of Vibrio cholerae and the exact species identification were done by performing the following tests oxidase reaction, growth in 0% , 1% , 3% , 6% salt solution, lysine and ornithine decarboxylase, Arginine dehydrolase, ONPG and VP test, simmon citrate, bile esculin, indole, CAMP reaction, string test and specific antisera to V.cholerae 01. to confirm the findings, the special antiserum Ogawa and Inaba, were used. Results: We were able to isolate 42 Vibrio spp. from a total of 54 water samples collected. The species included 35 non-01 V.cholerae (84.2%), 2 V.mimicus (2.63%) and 5 V.cholerae 01 (13.1%) isolat. Conclusion: This study confirmed the existence of Vibrio cholerae 01 in 9% of samples from surface waters of Golestan province.
