[The evaluation of the vibriocidal antibody test in establishing a diagnosis of cholera or Vibrio carriage]

Abstract

On the basis of the serological survey of cholera patients, vibrio carriers and persons having had contacts with the source or reservoir of Vibrio cholerae the conclusion has been made that the test for the presence of vibriocidal antibodies, together with the bacteriological study of the patient, is of diagnostic importance in the diagnosis of cholera or vibrio carriership. The detection of vibriocidal antibodies, especially in the study of paired sera, permits the detection of cholera cases which have not been bacteriologically confirmed due to various reasons; besides, it makes it possible to exclude the diagnosis of cholera made only on the basis of clinical data. Like bacteriological study, the determination of vibriocidal antibodies must be obligatory for persons hospitalized in a provisory hospital or an isolation ward; it will undoubtedly improve the quality of cholera diagnosis and permit taking timely antiepidemic measures in the focus of infection.
