BACTERIA IN INFECTIOUS DISEASES. 591 



pyogenes ; in two Staphylococcus pyogenes aureus ; in two Bacillus 

 endocarditidis griseus ( Weichselbaum) ; in one Micrococcus endo- 

 carditidis rugatus (Weichselbaum); in one Bacillus endocarditidis 

 capsulatus (Weichselbaum); in two cases a bacillus which he did 

 not succeed in cultivating. For further details see the descriptions 

 of microorganisms referred to. 



Howard (1893) reports a case of acute ulcerative endocarditis in 

 which the diphtheria bacillus was present in pure culture also ob- 

 tained in cultures from the liver, spleen, and kidneys. In a case of 

 malignant endocarditis in a patient with gonorrhoea and gonorrhoeal 

 rheumatism, Leyden (1893) found the gonococcus in the vegetations 

 upon the valves. Banti (1894) in 22 cases examined obtained 

 Streptococcus pyogenes in 7, Staphylococcus pyogenes aureus in 1, 

 these two microorganisms associated in 3, the micrococcus of pneu- 

 monia in 8 ; in 2 no bacteria were found. Dessy (1894) also exam- 

 ined 22 cases and had a negative result in 2. In the cases in 

 which bacteria were present he found " Diplococcus lanceolatus cap- 

 sulatus " (Micrococcus pneumonias crouposaa) in 8, Streptococcus py- 

 ogenes in 7, Staphylococcus pyogenes aureus in 1, Staphylococcus 

 pyogenes aureus and Streptococcus pyogenes associated in 3, Staphy- 

 lococcus pyogenes albus and Diplococcus lanceolatus in 1. 



ENDOMETRITIS. 



La Place (1892) has reported the results of his bacteriological investiga- 

 tions of the secretions of the endometrium and cervix uteri in health and dis- 

 ease. He found numerous bacteria in the normal secretions, but vastly more 

 in secretions from the inflamed endometrium, "the superficial exfoliating 

 cells also containing them." "In chronic endometritis the secretions con- 

 tain about as many infectious organisms, the mucous membrane and fibrous 

 tissue become greatly hypertrophied under the continued development of 

 these organisms, and whether this chronic condition be simple or gonor- 

 rhceal, we find the germs both in the epithelium and fibrous tissue." The 

 microorganisms obtained from the secretions of women with endocervicitis 

 were the ordinary pus cocci, Bacillus pyocyaneus, and certain other bacteria 

 designated by the letters, x, y, and z. 



Wolf (1893), in the secretions from the uterus in eight women suffering 

 from endometritis, found micrococci to be most numerous ; but in two cases 

 bacilli were found, and in one a vibrio somewhat resembling Koch's "com- 

 ma bacillus." This he describes under the name of Bacillus choleroides. 



ERYSIPELAS. 



Due to infection by Streptococcus pyogenes (No. 5) . 



ERYTHEMA. 



Cordua (1885) obtained from a series of cases of an erysipelatoid skin 

 affection of the fingers and hands, which he identified as corresponding with 

 erythema exudativum multiforme of Hebra, a micrococcus resembling 

 Staphylococcus pyogenes albus in its biological characters, but which he de-
