Fecal specimens of 11 horses were studied in order to determine the enteric bacterial flora of the intestinal tract of healthy horse. Then, in 5 of 11 horses the fecal cultivations were made continuously at proper intervals for a long period, and the cultures isolated were examined serologically. The results may be summarized as follows : 1. Enteric bacteria in the intestinal tract of healthy horses examined varied extensively in numbers with individuals. About 2.6 billion bacteria per gram of raw materials were encountered in 1 feces, but only 21 thousand in another. 2. The cultures isolated from feces of 11 horses were classified as Escherichia coli, E. freundii, Klebsiella, Cloaca and Proteus mirabilis. E. coli was the most common bacteria among them, but in some cases E. freundii or Klebsiella was the dominant bacteria. In the feces of healthy horses the occurrence of Proteus is rare, and if it should be present, it is very inferior in numbers. 3. It was ascertained that the E. coli flora in the intestinal tract of horses comprised 2 kinds of microorganisms, residents and transients, similar to the human bowel. 4. E. freundii and Klebsiella were present as residents, over a period of 3 months, in 2 of 5 horses examined.
