Little, DVM, PhD, DEVPC 2) The parasite shown in Figure 2 was removed from a subcutaneous cyst on the neck of a 3-month-old barn cat. Although the prognosis after successful removal of this parasite is good, occasionally these parasites will migrate aberrantly in kittens and older cats, resulting in which clinical presentation? Figure 1 The brown dog tick, Rhipicephalus sanguineus, is unusual in that it survives inside homes and kennels, feeding on dogs in all stages of its life cycle and, thus, is frequently found on dogs across the United States. It can be identified by its solid-brown color, relatively short mouthparts, and laterally projected basis capituli (Figure 1). Historically considered to have a strict preference for dogs, this tick was recently implicated in an outbreak involving the transmission of which of the following agents to dogs and people? 1) Figure 2 Signs of neurologic disease due to migration in the central nervous system Pruritic skin lesions associated with tortuous tracts of inflammation in the dermis Hepatomegaly and splenomegaly due to visceral migration of larvae mixed-breed dog from southern Missouri was presented 3) A 5-year-old early June with numerous ticks attached (Figure 3A). The for evaluation in dog was febrile and depressed. A complete blood count showed a normocytic, normochromic, nonregenerative anemia and mild thrombocytopenia. A blood smear revealed the organisms seen in Figure 3B. What is the most appropriate treatment? Doxycycline, 10 mg/kg once a day for 28 days Amoxicillin, 20 mg/kg twice a day for seven days Enrofloxacin, 5 mg/kg once a day for 14 days Borrelia burgdorferi, the agent of Lyme disease Rickettsia rickettsii, the agent of Rocky Mountain spotted fever Trypanosoma cruzi, the cause of Chagas disease, or American trypanosomiasis, in both dogs and people Figure 3A Figure 3B 1,000X VETERINARY MEDICINE August 2008 423
