exudate in the peritoneal cavity; hemorrhagic necrosis occurs following intradermal 

 inoculation of the rabbit; agglutinated by antisera to Bordelella pertussis

98. Organisms usually 0.2 to 0.5 micron wide and 0.5 to 2.0 microns long but frequently 



produce long filaments; do not grow on nutrient agar without the addition of X 

 factor or V factor or both or the addition of diphosphothiamine or adenosinetri- 

 phosphate; colonies on suitable media rarely more than 1 mm in diameter after 2 

 days' incubation; various species have been reported as responsible for or associated 

 with viruses in: 



(i) Purulent meningitis and conjunctivitis in man {H. influenzae) 

 (ii) Sub-acute endocarditis {H. haemolyticus) 

 (iii) Acute and sub-acute conjunctivitis in man (H. aegyplius) 

 (iv) Soft chancre {H. ducreiji) 



(v) Vesicular eruptions in the genitals of cattle {H. citreus) 

 (vi) Ulcers of trout (H. piscium) 

 (vii) The respiratory tract of man (various species) and preputial secretions of 



dogs {H. haemoglobinophilus) 

 (viii) Pharyngitis (H. parahaemolyiicus) 

 (ix) Non-pathogenic {H. parainfiuenzae) 

 (x) Fowl coryza {H. gallinarum) 

 (xi) Swine influenza {H. suis) 



(xii) Respiratory tract of ferrets {H. pulorioram) 

 Of the above, H. ducreyi and H. putoriorum are the ones most likely to terminate 

 here. The others may do so owing to variation in biochemical reactions

99. Organisms grow in a mineral salts medium with an alkylamine as the sole source of 



carbon and nitrogen Protaminobacter p. 200 



Not as above 100 



100. Organisms found growing in waters among decomposing plant tissue; coccobacillary 



forms embedded in a gelatinous matrix which usually forms in long finger-like proc- 

 esses in which the cells are well isolated from each other; produce a zoogloeal mass 



and cartilaginous colonies in culture Zoogloea p. 206

101. Litmus milk alkaline 102 



Litmus milk acid or unchanged Achromobacter p. SCO 



102. Colonies on nutrient agar colorless; up to 1 mm in diameter in 5 days at 28° C; grow 



autotrophically, oxidizing sodium thiosulfate to sodium sulfate and sulfuric acid

 drates.

104. Colonies yellow; flagella polar Xanthomonas p. 152 



{X. plantaginis and X. conjac (if lactose-negative) terminate here.) 

 Colonies not yellow 105 



105. Organisms produce a luminescent growth on agar containing 2.8 to 3.0 per cent salt; 



usually no luminescence on media with the usual 0.5 i)er cent salt
