Abstract
Seven serological groups of Veillonella were found. The generic and species descriptions are enlarged and corrected. The type species is Veillonella parvula (Veillon and Zuber) Prevot, 1933. The proposed species, subspecies (infraspecific serogroups), and American Type Culture Collection (ATCC) type strains are: V. parvula subsp. parvula subsp. nov. (antigenic group-VI), ATCC 10790; V. parvula subsp. rodentium subsp. nov. (antigenic group-II), ATCC 17743; V. parvula subsp. atypica subsp. nov. (antigenic group-V), ATCC 17744; V. alcalescens subsp. alcalescens subsp. nov. (antigenic group IV), ATCC 17745; V. alcalescens subsp. ratti subsp. nov. (antigenic group-in), ATTC 17746; V. alcalescens subsp. criceti subsp. nov. (antigenic group-I), ATCC 17747; and V. alcalescens subsp. dispar subsp. nov. (antigenic group-VII), ATCC 17748. The following species listed in Bergey''s Manual (7th ed.) are rejected as members of the genus: V. discoides, V. reniformis, V. orbiculus, and V. vulvovaginitidis.
