PYOGENIC COCCI 171 Morax-Axenfeld Diplobacillus of Conjunctivitis.â This bacillus is foxmd in the greater number of cases of con-junctivitis. Form.â^A short, plump bacillus, usually ia pairs and chainsof pairs. Non-motile (Fig. 82). Growth.â^With difficulty in blood-serum agar, it forms smallpitted colonies or lacunae; liquefies. Staining.â^Does not take Gram, but stains readily. Non-pathogenic for lower Fig. 82.â^Morax-Axenfeld diplobacillus from conjunctival exudateduring coiurse of subacute conjunctivitis (obj. B. and L., one-twelfth oil-immersion) (Boston). Bacillus Pyocyaneus (Gessard).âSynonyms.âBacillusfluorescens (Schroter); the bacillus of bluish-green pus. Origin.âFound in 1882 in green pus in pyemia. Has beenfound in water, in bandage material, in feces and street dust,in the mouth of healthy individuals, and in all suppuratingconditions, especially in middle-ear discharge. Form.âSmall slender rods with rounded ends, easily mis-taken for cocci. Often in groups of four and six, withoutspores. 172 ESSENTIALS OF BACTERIOLOGY Properties.âVery motile; liquefy gelatin rapidly; a pecu-liar sweetish odor and a blue pigment are produced in thecultures. GVoze)^A.âDevelops readily at ordinary temperature, grow-ing quickly and mostly on the surface; it is aerobi
