CHAPTER VII. 



PYOGENIC OBGANISKS. 



Pus formation is not necessarily due to bacteria — Organisms of 

 pus — Staphylococcus pyogenes oMreus — Methods of staining 

 and growth on media — Staphylococcus pyogenes alhus — Other 

 staphylococci — Bacillus pyocyaneus. 



EEYSIPEtAS. 



Fehleisen's streptococcus — Growth on media — Media must con- 

 tain peptone — ^Virulence is more rapidly lost ia broth than in 

 solid media — Occurrence and distribution — Pathogenesis — 

 Exhibits varying degrees of infectivity — The possible identity of 

 the organism with the Streptococcus pyogenes — Practical dis- 

 infection, 



GONOBBHCEA. 



Specific organism first discovered by Neisser — Cultivated by 

 Bumm— Method of staining — Special media necessary for cul- 

 ture — Pathogenicity demonstrated by Bumm — In gonorrhoea 

 the gonococcus is associated with other micro-organisms — 

 Researches of Bosc — Bacteriological analysis — Practical pre- 

 cautions. 



GLANOEBS. 



The bacUlus of glanders was first described by Loffler and Schutz 



— Proof of its specificity — Morphology — Method of growth ia 



culture — Attenuation occurs rapidly in culture — Susceptible 



animals — Farcy — Diagnosis of glanders — -MaUein — Preventive 



measures. 



SYPHIIIS. 



Syphilis appears to belong to a group, the other members of 



which are tuberculosis, leprosy and glanders — Lustgarten's 



bacillus is probably the specific organism — Some observers 



have described streptococci — Methods of staining — Growth on 



media — Bacillus of Eve and Lingard — Capsulated diplococcus
