Viabilidad del Vibrio cholerae O1 en el medio de transporte de Cary-Blair

Abstract

During the recent outbreak of cholera in Colombia we tried to established the survival time of Vibrio cholera01 in Cary-Blair transport medium. The viability was determined during six weeks, in 53 samples kept in the laboratory at room temperature (23°C + 2) The recovery was 94% in the first week, and 89%, 87%, 83%, 81% respectively in the second, third, fourth and fifth weeks and 72% in the sixth week. Additionally, the recovery of v. cholerae O1 was directly dependent upon the amount of microorganisms present in the stool sample. Our results allowed us to select Cary-Blair transport medium as an ideal one for shipping samples to the reference center.
