Their specificities were studied by agglutination and EIA. Five antibodies reacted with some, but not all, members of the Sejroe and Hebdomadis serogroups, and one antibody agglutinated exclusively members of the Sejroe group thus indentifying a serogroup-specific epitope. None of the six antibodies reacted with representative serovars of any other serogroup., UL https://www.microbiologyresearch.org/content/journal/jmm/10.1099/00222615-23-1-1
