MEDICAL BACTERIOLOGY 



The Pure Cultivation of Spirochaeta Icterohaemorrhagiae (Inada) . T. Ito 

 AND H. Matsuzaki. Jour. Exp. Med., 1916, 23, 557-562. 

 This organism, claimed to be the causative agent of Weil's disease, 

 was obtained by the authors in a solid, a semi-solid, and a fluid medium, 

 enriched with blood. The spirochaete thus isolated remains patho- 

 genic for guinea pigs for many generations. The characteristics of 

 three strains are described. — B. W. 



A Milk-Borne Paratyphoid Outbreak in Ames, Iowa. Max Levine 

 AND Frederick Eberson. Jour. Infect. Diseases, 1916, 18, 143-150. 

 The authors explain a slight epidemic on the grounds of a paratyphoid 

 B. infection originating either from a carrier or from a convalescent. 

 The paratyphoid cultures isolated, it is stated, produced gas in glu- 

 cose broth.— P. B. H. 



A Leptothrix Associated with Chronic Hemorrhagic Nephritis. G. R, 

 Dick, G. F. Dick, and B. Rappaport. Jour. Infect. Diseases, 

 1916, 18, 216-219. 



The authors report a case of chronic nephritis characterized by recur- 

 ring attacks of hematuria probably caused by a Leptothrix which was 

 present in the urine. The causal relation was suggested by the con- 

 stant occurrence of the organism, its virulence for animals and the 

 improvement in the case which took place under vaccine treatment.

Technique of Cultivating Human Tissues in Vitro. R. A. Lambert. 



Proc. Soc. Exp. Biol, and Med., 1916, 13, 100-101. 



Chick plasma with the addition of an equal quantity of human serum 

 furnishes a satisfactory medium, in which the fibrin network resists 

 digestion. Human tissue may be preserved in viable condition for 

 five to ten days, by immersion in salt solution in a cool place. The de- 

 struction of bacteria in infected tissues by means of chemical disinfec- 

 tants is being investigated. — W. J. M. 



The Cytology of the Exudate in the Early Stages of Experimental Pneu- 

 monia. Frank A. Evans. Proc. Soc. Exp. Biol, and Med., 1916, 

 13, 99-100. 



Pneumonia was induced in rabbits by intrabronchial injection of 

 pneumococci and streptococci and by the injection of egg yolk. The 

 exudate in each instance contained many polynuclear cells but more 

 often the predominant cells were mononuclear. — W. J. M. 



Pneumotyphoid, with Report of a Case. F. Billings. Am. Jour. Med. 



Sc, 1916, 151, 36-39. 



Billings reports a case which "seems to present an example of typhoid 

 fever presenting its primary manifestations in the lung in the form of
