 Note: (1) From published data the following organisms, if isolated from the 

 soil, may terminate here: Agrobacterium rhizogenes, Erwinia amylovora, E. 

 aroideae, Rhizohium leguminosarum , R. trifolii and R. phaseoli. 

 In addition the following may also be listed if they prove to be lactose fer- 

 menters: Achromobacter delicatulum, A. superficiale , Agrobacterium tumefa- 

 ciens, Rhizobium meliloti and Erwinia salicis.

63. Encapsulated organisms; pathogenic, causing infections in man and animals, princi- 



pally of the respiratory tract Klebsiella p. 344 



Not as above Aerobacter p. 341 



{Klebsiella {Klebsiella- Aerogenes) Group, Rome, 1953) 



64. Small, ovoid coccobacilli causing pneumonia in sheep and cattle 



Pasteurella p. 395 

 Organisms which produce mucoid to cartilaginous colonies adherent to the medium; 

 grow on meat infusion agar; colonies usually 1 mm in diameter in 24 hours but may 

 enlarge on further incubation to 3 to 6 mm ; produce a granulated growth on the walls 

 of the tube in liquid media; occur in necrotic lesions as granules resembling actino- 

 mycotic granules in cases of actinobacillosis of cattle and joint ill of foals or in 

 complicating actinomycotic infections. One species may be a commensal in the ali- 

 mentary canal of solipeds Actinobacillus p. 4H 



Not as above 65 



65. Fastidious organisms; do not grow on meat infusion agar in the absence of X-f actor 



on primary isolation under aerobic conditions but may be trained to grow without it; 

 colonies on blood agar 0.5 mm in diameter but may be much larger on Levinthal 

 agar; coccobacillary, arranged singl}% in short chains or in clumps 



Haemophilus p. 406 

 Species represented here cause bronchopneumonia of sheep {H. ovis), respiratory 

 infection in mice {H. influenzae-murium) and endocarditis {H. aphrophilus) . 

 Fastidious organisms; require blood or ascitic fluid; highly pleomorphic; rod -shaped
