Abstract

Maki, Leroy R. (University of Wyoming, Laramie), and Kay Picard. Normal intestinal flora of cattle fed high-roughage rations. J. Bacteriol. 89:1244–1249. 1965.—Intestinal bacteria were isolated from 15 cattle. Approximately 600 isolates were studied, and their presence and numbers in the duodenum, ileum, cecum, and colon were noted. Bacteria most frequently isolated from all parts of the intestinal tract included Escherichia coli, Streptococcus bovis, and species of Bacillus. Several groups of gram-positive rods could not be classified according to Bergey's Manual. Direct counts of intestinal contents indicated that 1 to 10% of the bacteria present were recovered.
