Abstract
A study was performed of 342 disease-related strains of meningococci isolated in Switzerland and France between 1980 and 1986, including more than 50% of all strains isolated in Switzerland in 1986. Using a newly developed spot-blot enzyme-linked immunoassay and a panel of monoclonal anti-meningococcal antibodies, 96% of all strains were shown to react with at least one antibody. In both countries more than 50% of the strains were group B. In France serotype 2a was the prevalent serotype and was often associated with subtype P1.2. In Switzerland serological markers of epidemic strains recently described in Northern Europe (serotype 15 and subtype P1.16) were observed with increasing frequency in 1986. However, serotype 4 has been prevalent in Switzerland since 1980 and no clonal population was seen to emerge.
