[Sepsis due to Vibrio cholerae no 01].

Two fatal sepsis cases in two male patients (58 and 14 years old) due to Vibrio cholerae non 01 are described. Their original diseases were hepatic cirrhosis and acute lymphoblastic leukemia in its third complete remission. In this last case, gastroenteritis due to V. cholerae non 01 was also diagnosed. These sepsis presented a rapid evolution and positive hemoculture after 24 and 48 hours of incubation. Both strains isolated presented similar biochemical characteristics and did not agglutinate in the presence of the specific serum against V. cholerae. Both strains were susceptible to most of the antibiotics available. Sepsis due to V. cholerae non 01 is usually associated to other original diseases and to immunodepression. Management of these sepsis is difficult and mortality rates are very high.
