ABSTRACTS OF AMERICAN BACTERIOLOGICAL 

 LITERATURE 



ANIMAL PATHOLOGY 



Notes on the Histo-Pathology of the Intestines in Young Chicks Infected 

 with Bacterium pullorum. G. Edward Gage and James F. Martin. 

 (Jour. Med. Res., 1916, 34, 149-155.) 



Typical strains of Bacterium -pullorum, when injected into young 

 chicks, produced death with characteristic symptoms of bacillary white 

 diarrhea in 49 per cent of the animals. Chicks which survived the in- 

 jection showed retarded growth and general weakness. The chief patho- 

 logic changes on section were marked injury to the mucosa, associated 

 with hyperemia, hemorrhagic exudation and leucocytic infiltration.

The Diptheroid Bacillus of Preisd-Nocard from Equine, Bovine and 

 Ovine Abscesses. Ulcerative Lymphangitis and Caseous Lymphadeni- 

 tis. I. C. Hall and R. V. Stone. (Jour. Infect. Diseases, 1916, 18, 

 195-208.) 



The authors call attention to the presence in the United States of 

 the bacilkis of Preisz-Nocard, which they isolated from horses and 

 from a calf. They point out the uncertain significance of experimental 

 orchitis in guinea-pigs as a test for glanders, and emphasize the neces- 

 sity of microscopic and cultural examination of pus for diagnostic pur- 

 poses. — P. B. H. 



BACTERIOLOGY OF SOILS 



Studies in Sulfojication. P. E. Brown and H. W. Johnson. (Soil 



Science, 1916, 1, 339-362.) 



It is suggested that applications of sulfur-containing commercial 

 fertihzers to soils will prove profitable unless different methods of soil 

 treatment are employed than those in use at present, because at some 

 future time sulfur will be lacking. In other words, for permanent soil 

 fertihty, the sulfur supply for crops must be considered. Chemical 

 tests were made for determining sulfofication produced in a sulfur-rich 

 soil to which various chemicals were added. — Z. N. 



Preliminary Experiments on Some Effects of Leaching on the Soil Flora. 

 C. B. Lipman and L. W. Fowler. (Soil Science, 1916, 1, 291-297.) 

 It seems that leaching affects the bacterial flora of soils profoundly. 



Nitrification, nitrogen-fixation and cellulose decomposition are wholly
