Question 1: This camel is showing signs of

tetanus .The organism was likely introduced into the body through the castration wound . It is recommended that camels are vaccinated against tetanus prior to castration. Reference: Trop Anim Health Prod. 2004 Apr;36(3):217-24.While rabies may cause paralysis of the tongue and difficulty swallowing , the recent history of castration in this camel makes tetanus most likely.Trypanosoma evansi is transmitted via biting flies and causes a slow wasting disease in camels.

Answer:

You are called out to examine a 4-year old dromedary who was castrated 10-days ago and is now not eating. The groin and prepucial area is extremely swollen. The camel is unable to stand and is drooling.His neck is extended and he appears to be unable to swallow. Which of the following is most likely responsible for these symptoms?

• Methicillin-resistant Staphylococcus aureus

• Trypanosoma evansi

• Rabies virus

• Clostridium tetani

Question 2: Significant knowledge about Strontium is not necessary to answer this question correctly.The principle of ALARA (as low as is reasonably achievable) should always be followed when dealing with radiation , regardless of the type of radiation. This means that you should always take reasonable steps to keep radiation dose to personnel as low as you reasonably can.The 3 main ways to decrease radiation dose are to increase the distance of personnel from the radiation source, to decrease the time of exposure of personnel to radiation, and to use appropriate shielding to decrease radiation to personnel

• zuku flashcard question.

The same principle holds true for pregnant women. There are acceptable exposure limits for pregnant women (the most commonly used is <0.5 milliSieverts per month during pregnancy).If steps are taken to keep exposure as low as reasonably achievable, pregnant woman would be able to handle the Strontium probe and keep the dose well below these limits

Answer:

The snake in the image below is being irradiated with a Strontium-90 probe. Strontium-90 radioactively decays and emits beta particles which allow delivery of very high doses of radiation to a small superficial area. All of the following are considered important principles of radiation protection for personnel (radiation workers) that should be followed EXCEPT for which of the following?

• Plexiglass sheilding should be usd to decrease radiation exposure to personnel

• Pregnant women should NOT handle STRONTIUM probe.

• All personnel should hold the strontium probe for the minimus amount of time that is necessary

• All personnel should stand as far away from the strontium probe as is reasonably achievable.

Question 3: The correct answer is

Pasteurella multocida . This is a common cause of infectious disease in rabbits and is the causative agent of "snuffles" .Of the choices listed, Pasteurella is the only respiratory pathogen.The upper respiratory syndrome is the most common presentation for Pasteurella in rabbits, but it can affect many other systems and can cause enzootic pneumonia, otitis media/interna, conjunctivitis, meningitis, encephalitis, reproductive tract infections, abscesses , and septicemia

Answer:

An adult rabbit presents to you for chronic mucopurulent nasal discharge and sneezing. Which of these agents is likely responsible for the rabbit's clinical signs?

• Clostridium spiroforme

• Pasteurella multocida

• Treponema cuniculi

• Eimeria stediae

Question 4: Liver biopsy provides the most definitive diagnosis in birds since pathology is readily seen on microscopic examination of liver tissue.Hemochromatosis occurs when too much iron accumulates in the liver and other major organs of the body.The etiology of this disease remains unknown but owners and breeders receive conflicting information regarding the influence of captive dietary iron levels and *genetics.Blood tests such as serum iron levels , plasma iron binding capacity unfortunately provide inconclusive results.

Answer:

A Toco toucan is presented to your clinic with nondescript signs of lethargy and weight loss. The owner of this valuable bird perused the internet and found that this species of bird is highly susceptible to hemochromatosis, or iron storage disease. You run a CBC and chemistry panel and both bile acids and AST are mildly elevated. Radiographs reveal an enlarged liver. What test would you recommend to confirm your tentative diagnosis of hemachromatosis?

• Bone marrow biopsy for iron levels

• Liver biopsy

• Liver hemotropin levels

• Blood iron levels
