General Consideration of Spirillaceae. This family of bacteria has thus far revealed very few species that are pathogenic for domesticated animals. § 222. Diseases of fowls caused by spirillaceae. The disease of fowls reported to be caused by these organisms has not been found in this country. It is not unlikely that some one or more of the many â 'a» * ' - \ as yet mysterious diseases of \ poultry may be caused by members of this family. It is interesting to note that spirilla are not uncommon in the bac- terial contents of the intes- tines. It is believed that many of these are anaerobes, which would explain the diffi- culty encountered in trying to isolate them in pure culture. Sakharoff studied, in 1891, a peculiar disease of geese and showed it to be caused by a spirillum. It was designated spirochacte anserina. Cantacuzene has studied the mode of destruction of the spirilla. He found that they are destroyed by and within the macrophages of the spleen. The morbid anatomy in the affections caused by the spirilla appear to be largely engorgement of the spleen and Fig. 67. Spirochaete anserina fro'Di the blood of a goose {after Cantacuzene).
