DESCRIPTION OF SPECIES. 



517 



guinea-pigs and rabbits gave doubt- 

 ful results. They were found in 

 the deeper stratum of pseudo- 

 diphtheritic patches in calves. 



Bacillus in disease of l)ees (p. 

 471). 



Bacillus in erythema nodosum 

 (Demme). — Rods 22 to 2'5 fi. in 

 length, '5 to '7 /j. in width. They 

 can be cultivated at 37°C. 



Colonies on agar are white with 

 radiating lines. 



The bacilli inoculated in the depth 

 of agar grow in the track of the 

 needle, and produce peculiar off- 

 shoots in the surrounding jelly. 



They are said to produce an 

 eruption resembling erythema 

 nodosum when inoculated subcu- 

 taneously in guinea-pigs. 



They were obtained from the 

 eruption and the blood in cases of 

 erythema nodosum. 



Bacillus in fowl enteritis 

 (Klein), p. 230. 



Bacillus in gangrene (Tricomi). 

 — Rods 3 fi in length, 1 /i in width, 

 singly and in pairs. 



Colonies circular, granular, dirty- 

 yellow. 



In the depth of gelatine they 

 produce a filament composed of 

 closely aggregated colonies, and at 

 the upper part conical liquefaction 

 of the jelly, beneath a cup-shaped 

 excavation. 



On agar and potato the growth 

 is white. 



Injectedsubcutaneously in rabbits 

 and guinea-pigs they produce gan- 

 grene and death in a few days. 



They were isolated from a case 

 of senile gangrene. 



Bacillus in grouse disease 

 (Klein), p. 230. 



Bacillus in hog cholera (p. 

 361). 



Bacillus in infantile diarrhoea 

 (Booker). — Rods morphologically 

 identical with Bacillus coli com- 

 munis. There are seven varieties 

 of this bacillus. They were iso- 

 lated from cases of infantile diar- 

 rhoea. 



Bacillus in infantile diarrhoea 

 (Lesage). — Rods 2-4 n in length, 

 "75 /x in width, and filaments. 



Colonies irregular ia contour, 

 colouring the gelatine green. 



On the surface of agar they form 

 a greenish growth, and the gelatine 

 is coloured green. 



Injected intravenously in a rabbit 

 they produced diarrhoea. 



They are said to be identical with 

 Bacillus fluorescens liquefaciens 



Bacillus in intestinal diph- 

 theria in rabbits (Ribbert). — 

 Rods 3 to4 /i in length, 1 to 1'4 /i 

 in width ; singly, in pairs, and in 

 filaments. 



Colonies greyish ; granular. 



They produce in gelatine a deli- 

 cate growth in the track of the 

 needle. They are pathogenic. 



They were isolated from the 

 intestine of rabbits suffering from 

 a diphtheritic inflammation of the 

 mucous membrane. 



Bacillus in jequirity infusion 

 (see Bacillus of Saltier). 



Bacillus in measles (p. 283). 



Bacillus in noma (Schimmel- 

 busoh). — Rods singly, in pairs, and 

 filaments. 



Colonies circular, greyish-white, 

 granular, with irregular margins. 



In the depth of gelatine they 

 produce agranular filament anda 

 patch on the surface. 



On agar and potato the growth 

 is greyish-white. 



They are pyogenic in rabbits. 



They were inoculated from a 

 case of noma. 



Bacillus in ophthalmia (p. 190). 



Bacillus in potato rot.— Rods 

 2'5 to 4 /* in length, '7 to -8 fj. in 

 width ; singly, in chains, and in fila- 

 ments. Spore-formation present. 



The bacilli inoculated in the 

 depth of gelatine produce a funnel- 

 shaped area of liquefaction. 



On agar the growth is composed 

 of greyish-white slimy colonies. 



They were isolated from diseased 

 potatoes. 



Bacillus in purpura hsemor- 

 rhagica (Tizzoni and Giovannini). 

 —Rods -75 to 1-3 fi in length, -2 to 

 •4 /i in width, singly, in pairs, and 

 in masses. 



Colonies have a greyish-yellow 

 nucleus and a marginal zone of fine
