Spirochetes of Relapsing Fever 



_0. rapubata is capable of harboring and transmitting other 

 Borrelia species besides B. duttonii. This is of considerable 

 interest since in other parts of the world many species of 

 Borrelia are host-specific and tick hosts are spirochete^specific. 



Spirochetes Other Than Relapsing Fever 



Weil's disease (Leptospira icterohaemorrhagiae ) survives for 

 about forty days in living 0. moubata , remains virulent in the 

 body long after the tick's ^eath, and can be transmitted when 

 infected ticks bite, 



Filariae 



Filariae may develop in the body cavity of 0. moubata but 

 transmission appears to be unlikely. "* 



Trypano somes 



Virulent trypanosomes may remain in the tick's gut for as 

 long as five years, but transmission is apparently impossible 

 and transovarial infection does not occur. 



Toxoplasmosis 



It appears that Toxoplasma gondii cannot be transmitted by 

 0. moubata although the organism survives in the tick for almost 

 two weeks after artificial inoculation. 



Tropical Ulcer 



The suggestion has been made that tick bites, such as those 

 of 0. moubata , may be initially responsible for tropical ulcer. 



IDENTIFICATION 



0, moubata might be confused only with 0. savignyi in the 

 African launaT" However, since 0, moubata lacks eyes, which in 

 0. savignyi are present as two pairs of small, round, equal sized,
