BACTERIA IN CROUPOUS PNEUMONIA. 313 



Netter this micrococcus was present in twenty-seven, Streptococcus 

 pyogenes in six, and the Diplococcus intracellularis meningitidis of 

 Weichselbaum in ten. 



Monti (1889), in four cases of cerebro-spinal meningitis, demon- 

 strated the presence of the same micrococcus. In three of his cases 

 pneumonia was also present. In two Staphylococcus pyogenes aureus 

 was associated with the " diplococcus pneumonias." 



Micrococcus Pneumonice Crouposce in Ulcerative Endocar- 

 ditis. Weichselbaum, in a series of twenty-nine cases examined 

 (1888), found " diplococcus pneumonise" in seven. 



Micrococcus Pneumonice Crouposce in Acute Abscesses. In a 

 case of parotitis occurring as a complication of croupous pneumonia 

 this micrococcus was obtained from the pus in pure cultures by Testi 

 (1889); and in another case in which, as a complication of pneumonia, 

 there developed a purulent pleuritis, abscess of the parotid on both 

 sides, and multiple subcutaneous abscesses, the pus from all of the 

 sources named contained the "diplococcus" in great numbers, as

shown not only by microscopical examination but by inoculation into

In a case of tonsillitis resulting in the formation of an abscess 

 Gabbi (1889) obtained the same coccus in pure cultures. 



In otitis media this micrococcus has been found in a consider- 

 able number of cases in the pus obtained by paracentesis of the 

 tympanic membrane, and quite frequently in pure cultures by Zau- 

 fal (1889) in six cases; Levy and Schrader (1889) in three out of ten 

 cases in which paracentesis was performed; by Netter (1889) in five 

 out of eighteen cases occurring in children. 



Monti (1889) and Belfanti (1889) report cases of arthritis of the 

 wrist joint, occurring as a complication of pneumonia, in which this 

 micrococcus was obtained in pure cultures. Ortmann and Samter
