The bacillus bipolaris septicus (Bac. multocida s. plurisepticus, Kitt; pasteurella, Lignieres, ovoid or girdle bacterium) mani- fests the following characteristics without consideration of the diseases belonging to this group or from what species of ani- mals it originates (Lignieres). It is short, stains intensely at the poles but only slightly in the middle, polymorphotis, non-motile, does not form spores, principally aerobic; does not stain by Gram, grows in bouillon, gelatin and agar, but does not grow on acid potatoes, nor liquefy gelatin, nor coagulate milk; it does not produce indol in pancreatic bouillon, nor redden Wirtz's agar; the bouillon cultures have a peculiar characteristic odor. Besides these characteristics of the bipolar baeillus, the special characteristics of the bacteria belonging to this group are the following: Form. In the tissue fluids and stil] more so in cultures the bacillus represents a short rod about 1/* long, with rounded ends (Fig. 23). It also occurs in the form of cocci, diplocoeci; exceptionally also as longer rods, threads and streptobacilli. Its dimensions vary according to the origin of the disease in certain although not wide Fig. 23. Bacillus hipolaris septicus. Fig. 24. Bacillus hipolaris septicus.
