5 8, Bartonella 



Two cultures of Bartonella bacilliformis were received from 

 Aristidis Herrer, Lima, Peru. Transfers to various blood media 

 grew the organisms rather scantily. The best preparations were 

 obtained from blood agar slants by suspending the growth in dis- 

 tilled water and washing in the usual manner. The organisms 

 showed much clumping and none of the preparations were par- 

 ticularly good. 



Flagellar Characteristics 



In spite of the frequent location of the flagella at the poles of 

 the soma the organism appears definitely to be peritrichous. The 

 flagellation was poor, the organisms usually in clumps, which left 

 few isolated, flagellated individuals on the slides. The flagellar 

 wavelength was very short, averaging 0.95 micron with an average 

 amplitude of 0.25 micron (Fig. 65).
