Determination of bactericidal antibodies directed against vibrio cholerae in an adult population in Montevideo

: Uruguay is the only Latinoamerican country that remains free of cholera. Thus, to obtain a baseline for future diagnosis vibriocidal antibodies were investigated in 100 sera from blood donors serogroup "O". The reaction was carried out in microplates with live antigen Ogawa VC 12. In 95% of sera, titers were below 160, suggesting a high degree of susceptibility to V. cholerae in the population.
