Cholera is caused only by O1 and O139 Vibrio
cholerae strains. For diagnosis, 3 working days are needed for
bacterial isolation from human feces and for biochemical
characterization. Here we describe the purification of bacterial outer
membrane proteins (OMP) from V. cholerae O1 Ogawa, O1
Inaba, and O139 strains, as well as the production of specific antisera
and their use for fecal Vibrio antigen detection.
Anti-OMP antisera showed very high reactivity and specificity by
enzyme-linked immunosorbent assay (ELISA) and dot-ELISA. An
inmunodiagnostic assay for V. cholerae detection was
developed; this assay avoids preenrichment and costly equipment and can
be used for epidemiological surveillance and clinical diagnosis of
cases, considering that prompt and specific identification of bacteria
is mandatory in cholera.
