Tick trivia: A clinical quiz
Test your knowledge of these little suckers and the diseases they transmit.
1) A 2-year-old intact female domestic shorthaired cat from central Arkansas is presented to the veterinarian because it is experiencing lethargy, a loss of appetite, and difficulty breathing. On physical examination, the cat is jaundiced, moderately dehydrated, and running a fever (104.3 F [40.2 C]). An examination of a Giemsa-stained blood smear reveals the organisms seen in Figure 1 (arrows). What treatment recommendation would you make?
2) A 5-year-old neutered male Brittany spaniel from Virginia is presented to the veterinarian lying on its side. The dog is alert and responsive but is breathing rapidly and unable to rise. A physical examination reveals an engorged female Dermacentor variabilis tick attached to the left side of the dog's neck, and a diagnosis of tick paralysis is suspected. The tick is removed by using forceps. If the suspected diagnosis is correct, what is the most likely outcome for this dog?
3) A 4-month-old intact male kitten from Pennsylvania that is allowed indoors and outdoors presents to the veterinarian with several small, attached ticks around its eyes. The ticks are removed and examined under a microscope, as seen in Figures 2 and 3. What are they?
