Trypanosomiasis: The causative organism of surra, Trypanosoma

 Another flagellate, Critl^dia christophersi , has been reportea to

Rabies; Tompkins (1953) compares textbook statements that

 vark is immortal because nobody has seen a dead one. He f axled to 

 become more rabid than this after serving as a host for a kennel

Canine Filariasis: The canine filaria, Dipetalonema ^assii , 

 is seTST^ be transmit ted by the kennel tick, which may also trans-

 So far as known , the role of R. s. sanguineus in the transmission 

 of these parasites in nature "Eas not been elucidated.

Mistaken Identity ; Cryptoplasma rhipicephali Chatton and
