One of the most striking accotants of R. s. sanguineus attack- 

 ing persons comes from the LaJce Region of ^exTcoTsirrzonHo Langagne 

 (19A7) wrote that this tick swarms in rural dwellings and indis- 

 criminately attacks persons or dogs. In this area more than five 

 hundred peasants, mostly yotmg children, presented themselves at 

 clinic for removal of adult ticks feeding in the canal of the 

 external ear. These ticks were considered responsible for the 

 cases of Rocky l-fountain spotted fever that were especially fre- 

 quent among children. 



Much further north, in the State of New York, Tompkins (1953) 

 found a specimen of this tick, that "had almost certainly left a 

 rabid fox" embedded in his own left axilla. Other laboratory 

 technicians exhibited - or refused to exhibit - tick bites on 

 various parts of their body, but the attacker species was not 

 identified. The hioman victims did not become rabid. 



Previously, Philip (1952) had noted the few instances in 

 which the kennel tick is known to have fed on people in the 

 United States and he summarized the small amount of available 

 data. A single case of a female tick biting a person, near 

 the ankle, in Nebraska has been presented (Helm 1952). Fiasson 

 (19^3A) indicates that this tick does not bite man in Venezuela. 



A notable Italian incident involved a female kennel tick 

 lodged in the ear of a person who suffered severe pain and 

 distress as a result (Condorelli Francaviglia 1913). The 

 Cameroons and Mexican cases noted above were also reported 

 from human ears. 



In his study of Indian tick typhus, Philip (1952) indicated 

 his belief that persons acquire this disease throTigh bites of 

 kennel ticks that have previously fed on infected dogs. There 

 are, however, very few records of this tick attacking man in 

 India. One such noted R. _s. sanguineus on a patient and on 

 his dogs. The patient "showed no eschar but clinically resembled 

 tick typhus; ticks from both kinds of hosts were infected but 

 the dogs were not (Rao 1951). Fotu: records of kennel ticks from 

 man in India were presented by Strickland and Roy (1939). In 

 Australia, this tick "seldom attacks man" (Roberts 1939).
