THE CLASSIFICATION OF BACTERIA 59 



Pathogenesis. Dogs and rabbits inoculated with 0.7-1.0 cc. of a culture sub- 

 cutaneously show a local abscess. By intravenous injections there 

 result inflammatory changes in kidneys. At the end of 3 days urine 

 contains red corpuscles, renal epithelium, blood clots, and albumen. 



Habitat. Isolated by Mannaberg from urine in acute Bright's disease. 



7. Str. enteritidis Escherich 



Wiener klin. Wochensch., 1887, No. 42. 



Morphology . Diplococci chains of 8 or more elements. In cultures similar 

 to M. lanceolatus. Stain by Gram's method. Grow best in glucose 

 bouillon, with addition of human blood serum. 



On agar, white colonies. On gelatin, a feeble growth, with slight liquefaction. 



Pathogenesis. Mice die in 2-3 days, with diarrhoea. 



Habitat. Isolated from acute enteritis, in stools, organs, and lymphatics of 

 the intestines. 



8. Str. Bonvicini 



Streptococcus delta leucemia net cane e nelbue Bonvicini : Centralblatt f. Bakteriologie, XXI, 



1897, 211. 



Morphology. Diplococci, and chains in old cultures; elements 0.9-1.0^.. 



Stain by Gram's method. 

 Agar colonies. In 24 hours at 37 C, colonies small, round, white. 

 Gelatin slant. In 40 hours, small white colonies. 

 Bouillon. In 24 hours at 37 C, medium turbid, becoming clear, with flocculi 



on the walls of the tube. 

 Pathogenesis. Dogs ; inoculations cause some disturbance with swelling of 



ganglia. Guinea pigs and mice, leucaemia. Rabbits, negative. 

 Habitat. Isolated from a dog in a case of leucaemia. 



9. Str. Fischeli 



Micrococcus No. 2 of Fischel : Zeitsch. f. Heilkunde, XII, 1891; 

 ref. Centralblatt f. Bakteriologie, IX, 611. 



Morphology. Cocci 1. 0-1.2; in pairs and chains. Stain by Gram's method. 

 Gelatin colonies. Milk-white ; liquefaction commences in 4 days, and progresses 



slowly. 

 Agar colonies. At 37 C, milk-white. 



Potato. 37 C, 8 days, thin, glistening, yellowish white ; at 20 C, no growth. 

 Milk. No growth.
