The Bacillus enteritidis as the Cause of Infectious Diarrhea in Calves. 

 K. F. Meyer, J. Traum, C. L. Roadhouse. (Jour. Am. Vet. Med. 

 Assoc, 1916, 49, 17-35.) t. a • u i 



In the course of an experiment on feedmg calves at the Agricultural 

 Experiment Station of the University of California, infectious diarrhea 

 or scours occurred in severe form. The etiological agent was deter- 

 mined to be of the paracolon type by all the identity reactions and sero- 

 logical tests; and was regarded as identical with B. enteritidis (Gartner). 

 Bacteriological findings were confirmed by feeding experiments with 

 two calves, of which one succumbed and one recovered.— A. R. W. 



A Filterable Orgaiiism Isolated from the Tissues of Cholera Hogs. D. J. 

 Healy and E. J. Gott. (Jour. Infect. Diseases, 1916, 18, 124-128, 

 1 1 \ 



In the course of a previous attempt to isolate a filterable virus from 

 the mesenteric glands of virus hogs, the technique involved the filtra- 

 tion of the glands immediately after grinding. In the present investi- 

 gation the gland tissue after grinding was suspended m 1 per cent glu- 

 cose neutral beef broth at 4°C. for five days, then put through a tested 

 Chamberland-Pasteur "F." The filtrate was divided between two 

 flasks, one of which was placed in a Novy jar, the other sealed, and both 

 incubated at 4°C. While the anaerobic preparation showed no growth 

 after thirteen days, the other flask showed a distinct growth after four 

 days. "This growth appeared as a fine sediment in the bottom of the 

 flask. " Upon agitation it " ascended through the fluid in the shape of a 

 small cloud. ..." This "filterable organism" grew best at 37 C. 

 but also at 20°C. and at 4°C. Hanging drop preparations revealed 

 clumps of a non-motile organism surrounded by a gelatinous material. 

 Satisfactory stained preparations were obtained by the Giemsa method. 

 In such preparations the organism appeared as a coccus or a small 

 bacillus 0.2 to 0.3/z in diameter. Subcultures were not obtained. In 

 tests with immune serum complement fixation was obtained with the 

 culture fluid in which the organism had been grown.— P. B. H.
