Rothenburger JL, Bennett KR, Bryan L, Bollinger TK.

Journal of Wildlife Diseases. 2015 Apr;51(2):503-8.

The picture above is taken from a necropsy of a wild snowshoe hare found suffering from neurologic disease. The dark arrows point to thick yellow exudate covering aborted fetuses within the uterus. What is the infectious etiology?

A. Listeria monocytogenes

I didn’t love the Listeria paper I had, so I found another one. Also on the reading list for those taking the test in 2020.

In a study of pinniped in the Baltic Sea, protozoal parasites prevalence was low. However metazoan parasites prevalence was high. What genus of acanthocephalan was common in this region and also the most common GI parasite in otariids in southern Brazil?

A. CorynosomaB. BolbosomaC. DiphyllobothriumD. AcanthocheilonemaE. Parafilaroides

Answer: A. Bolbosoma is also a common acanthocephalan but in cetaceans. The other can be eliminated because they aren’t acanthocephalans. Diphyllobothrium was common in the Baltic Sea study but is a cestode. Acanthocheilonema is a filarial worm that cross reacts with heart worm tests (Paper on that somewhere in the reading list) and Parafilaroides is a common pinniped lung worm

CLINICOPATHOLOGIC FEATURES OF INFECTION WITH NOVEL BRUCELLA ORGANISMS IN CAPTIVE WAXY TREE FROGS (PHYLLOMEDUSA SAUVAGII) AND COLORADO RIVER TOADS (INCILIUS ALVARIUS)

Helmick, Kelly E., Garner, Michael M., Rhyan, Jack, and Bradway, Daniel

Journal of Zoo and Wildlife Medicine, 49(1):153-161

Questions 2:

You are presented with a waxy tree frog (Phyllomedusa sauvagii) with a history of lethargy, anorexia, weight loss, swelling over the right lateral stifle, and decreased perching. You collect a skin swab and submit the sample to the lab for analysis. Based on molecular testing at the lab, they identify Ochrobactrum anthropic in the sample. What organism should you be suspicious of and what test could you perform to confirm the diagnosis?

Answer: A) Culture; B) Tuberculin Skin Test- advantage- standard in may cases for comparison, disadvantage- immobilization in the field twice in 72 hours; false positivesSerology- advantage- enables 1 time blood draw, allows for retrospective; disadvantage- not as sensitive (cell-mediated)
