Which of the following species suffers from high mortalities due to Brucellosis?
a. Alces alces
b. Odocoielus virginianus
c. Bison bison
d. Cervus canadensis
a. Alces alces - while most species do not have high mortalities from Brucellosis, moose do
O. virginianus - WTD do not
Bison do not
Elk do not
In which of the following species is transplacental infection with Brucellosis less likely?
a. Alces alces
b. Odocoielus virginianus
c. Bison bison
d. Cervus canadensis
d. Cervus canadensis - elk eat the placenta and clean the calving area thoroughly so transmission from placenta is an unlikely source
Which of the following is a consistent pathologic finding of adenovirus hemorrhagic diseases of deer?
a. oral ulcers
b. pulmonary edema
c. hemorrhagic enteritis
d. conjunctivitis
b. pulmonary edema
Which of the follwoing is known as "big head" in cervids but has low pathogenicity in mule deer and BTD?
a. Elaphostrongylus cervi
b. Elaphostrongylus rangiferi
c. Parelaphostrongylus tenius
d. Elaeophora schneideri
d. Elaeophora schneideri - lives in carotid and maxillary arteries mostly; mule deer and BTD are reservoir hosts with low path.
a. Elaphostrongylus cervi - muscle and cns
b. Elaphostrongylus rangiferi - muscle, CNS, lungs
c. Parelaphostrongylus tenius - CNS only; caribou>mule deer>BTD>moose
Which of the following is TRUE about Fasciola magna?
a. WTD are dead end host
b. lives in liver parenchyma
c. direct life cycle
d. prevalence within host decreases with age
b. TRUE-lives in liver parenchyma as opposed to other liver flukes which reside primarily in the bile duct.
WTD are reservoir/definitive host and have little dz but infections more severe in older animals. Life cycle is indirect with a snail (Lymnaea) as IH.

d. Dermacentor albipictus - winter tick of moose
Which of the following is the most important transmission method for chronic wasting disease?
a. saliva
b. rendered meat
c. colostrum
d. in utero
a. saliva - fecal oral transmission is most likely. Also infected tissues may persist for a long time in environment.
Wapiti, mule deer,and WTD are most susceptible
