HOSTS 



Antelopes are the most common hosts of adult H. aciculifer . 

 Other wild animals and domestic animals are rarely~attacked. 

 Rodents, small antelopes, and possibly hares appear to be the 

 chief hosts of the immature stages. 



Domestic cattle have been reported as hosts in Uganda (Wilson 

 1950A,C), Kenya (Lewis 1934 and Theiler 1945C), and the Union of 

 South Africa (Theiler 1945C). Lewis (1932A) noted a single spec- 

 imen from a domestic goat in a Somali village between Karati 

 Forest and Naivasha. Rousselot (l95l) reported a female from a 

 domestic dog in French Equatorial Africa. 



Antelopes hosts of adult ticks are the Uganda kob (Warburton 

 1913), reedbuck (Simpson 19U, Nuttall and Warburton 1915, Bed- 

 ford 1932B, Theiler 1945C), bushbuck (Lewis 1931C,1932A, Mettam 

 1932, Theiler 1945C), waterbuck (Lewis 1931C,1932A, Mettam 1932), 

 various duikers (Mettam 1932, Lewis 1932A), Thomson's gazelle 

 (Lewis 193A), oribi and Roosevelt's hartebeest (Biuatoria Province 

 records above), and tiang (Bahr El Ghazal Province record above).
