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., {887, 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 Kfi/^a^ Bonvicini : Centralblatt f. Bakteriologie, XXI, 



1897, 211. 



Morphology. Diplococci, and chains in old cultures; elements 0.9-1 .o/u.. 



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 Pischel : 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.
