152 BACTERIOLOGY 



79. Bact. rhinosclermatis (Trevisan) Migula 



Bacillus dtr Rhinoscleroms Frisch : Wiener med. Wochenschrift, 1882, 970. 

 Klebsiella rhinosclermatis Trevisan : Sul micrococco della rabbia, 1887, 8. 

 Bact. rhinosclermatis Migula: Die Naturlichen Pflanzenfam., 1895. 



Morphology. Bacilli short, with rounded ends, usually united in pairs and 



surrounded by a capsule ; or longer rods and filaments. 

 Gelatin colonies. Round, yellowish white ; microscopically granular. 

 Gelatin stab. In depth, densely crowded colonies ; on the surface, growth 



white, glistening, pulvinate. 

 Potato. Growth creamy white yellowish-brownish, in which gas bubbles 



may develop. 

 Milk. Coagulated (Paltauf ) ; not coagulated (Abel). 

 Pathogenesis. Mice affected by small doses. Intraperitoneal inoculations of 



guinea pigs and rabbits, in large doses, may cause death. Bacilli only 



sparingly in blood and organs. 

 Habitat. Found in newly formed tubercles in rhinoscleroma. 



80. Bact. Bordonii (Trevisan) 



Proteus hominis-capsulatus Bordoni-Uffreduzzi : Centralblatt f. Bakteriol., I, 1887. 



Klebsiella Bordonii Trevisan : Genera, 1889, 25. 



B. capsulatus-septicus Kruse : Flugge, Die Mikroorganismen, 1896, 345. 



Morphology. Bacilli variable in size, often irregularly swollen or curved; 



occur singly and in pairs or long filaments. Rods surrounded by a 



capsule. 

 Gelatin colonies. Like those of Bact. pneumonia, raised, but with irregular 



borders, or coli-like. 

 Gelatin stab. Growth like Bact. pneumonia. 

 Agar slant. Growth spreading, translucent. 

 Potato. Growth spreading, moist, glistening, colorless. 

 Blood serum. As on agar ; medium not liquefied. Gas produced in glucose 



bouillon according to Kruse ; not so according to Bordoni. 

 Bouillon. Turbid, with a pellicle on the surface ; no putrefactive odor. 

 Pathogenesis. Subcutaneous inoculation of mice causes death in 1-4 days of 



septicaemia. Intraperitoneal inoculations of rabbits and guinea pigs cause 



septicaemia and death in 2-3 days. 

 Habitat. Isolated from cadavers in cases of Hadernkrankheit.
