SUMMARY Four groups (1, 4, 5 and 6) of Gram negative, nonsporing anaerobic rods (family Bacteroidaceae) which have been isolated from the caeca of chickens, turkeys and ducks, are described. Two of the groups (1 and 6) belong to the genus Sphaerophorus but differ in a number of characteristics from named strains. The group 5 strains belong within the genus Bacteroides and resemble Bact. fragilis. The group 4 strains differ from Sphaerophorus and Bacteroides and have not yet been assigned to a genus. The methods used for isolating and identifying these organisms are discussed.
