🧍 According to Sakata et al. 2002, Bifidobacterium infantis Reuter 1963 (Approved Lists 1980) is a later heterotypic synonym of Bifidobacterium longum Reuter 1963 (Approved Lists 1980). This latter species can be divided into three biovars, namely the Infantis biovar, the Longum biovar and the Suis biovar, by molecular methods.
