to find evidence of spirochetes in domestic fowls from tampsin in- 

 fested dwellings in Tanganyika, a suggestion that these ticks do 

 not feed on fowls or do not transmit these organisms to fowls, 

 or else that Borrelia duttonii does not survive in fowls in nature. 



Along with A, persicus , Mitscherlich (1941 ) discussed the 

 ravages of 0. moubata in chicken houses in the Union of South 

 Africa and in Southwest Africa (= Deutsch Sudwest Afrika). It 

 is not, however, clearly stated that this writer actually saw 

 eyeless tsimpans in these situations. His remarks give the im- 

 pression of being based on the assumption that 0. moubata is an 

 important parasite of domestic chickens. "

Wild I'lammal Hosts 



See also "Wild" Habitats under Ecology below. 



A wild relative of the domestic pig, the varthog, Phacohoerus 

 aethiopicus subspp. , is a normal host of 0. moubata under condi- 

 tions not influenced by man. An African boy in Northern Rhodesia 

 has been observed emerging from a warthog biirrow with about thirty 

 nymphs biting him (Lloyd 1915). During a survey of the plains 

 south of Lake Edward in the Belgiaji Congo, Schv/etz (1933A} dis- 

 covered that 0, moubata was abvtndant in warthog burrows but rare 

 in native huts. Chorley (19A-3) found over forty specimens crawling 

 on a warthog shot in Uganda. He stated (personal conversation) 

 that all these specimens were nymphs. Heisch and Grainger (1950 ) 

 found numerous specimens in widely scattered warthog burrows in 

 Kenya and presented a theory on the relationship of wild and do- 

 mestic populations, discussed below in the section on **Wild"' 

 Habitats, iinder Ecology. A single specimen from a Northern Rho- 

 desian warthog and a large lot of nymphs from a Nyasaland warthog 

 burrow have been reported from material in the Nuttall collection 

 (Hoogstraal 1954C). Warthogs are also hosts in the Sudan, as 

 noted above and reported earlier (Hoogstraal 1954B). These mammals 

 also have been noted as hosts in Mozambique (Santos Dias 1952H, 

 1953B).
