🧍 Vandamme et al. 1997 demonstrate that Streptococcus difficilis corrig. Eldar et al. 1995 is a group B streptococcus belonging to the capsular serotype Ib group with a whole-cell protein pattern and phenotypic characteristics similar to those of other type Ib variants of Streptococcus agalactiae Lehmann and Neumann 1896 (Approved Lists 1980). The fish isolates classified as Streptococcus difficilis corrig. could represent a distinct marine variant of Streptococcus agalactiae.
