Quiz Answer Key and Fun Facts

1. Which of the following diseases is not related to dolphin morbillivirus?

Answer: Rabies

Other related viruses are rinderpest, phocine distemper virus type one, and porpoise morbillivirus.

2. Which animals are affected by dolphin morbillivirus?

Answer: Dolphins, porpoises, and whales

A morbillivirus affects only members of one mammalian order under natural conditions. In the case of dolphin morbillivirus, the order affected is Cetacea, which includes dolphins, porpoises, and whales. Major epidemics can occur if those creatures infected with the disease are exposed to populations that are not immune from the virus.

3. Humans can contract dolphin morbillivirus.

Answer: False

There is no known risk to humans from the virus. Humans have their own morbillivirus, measles.

4. How is dolphin morbillivirus primarily spread?

Answer: By breathing in the virus

The droplet nuclei of dolphin morbillivirus is breathed in during direct or indirect contact. Other entryways for the virus are the conjunctiva, the digestive tract, the urogenital tract, and skin wounds.

5. Which of the following conditions can be caused by dolphin morbillivirus?

Answer: Both of these conditions

These conditions make treatment difficult. Some cetaceans may be reservoirs of the virus and act as a vector for spreading it.

6. Which are clinical signs of dolphin morbillivirus?

Answer: Skin lesions and fast heart beat

Some other clinical signs are poor body condition, muscle tremors, an abnormal respiratory rate, and weak sound emission.

7. Where in the United States of America has dolphin morbillivirus been found in organisms?

Answer: East Coast

The disease has also been found in the Gulf of Mexico and the portion of the Pacific Ocean near California.

8. All individuals infected with dolphin morbillivirus strike their head against rocks or breakwaters.

Answer: False

This behavior has been found in some individuals but not others. There is a set of clinical signs, namely lethargy, lack of coordination, tachycardia, and tachypnea, that are found in only in common dolphins.

9. If a carcass is fresh, which body substance can be used to diagnose the virus?

Answer: Primary and secondary kidney cells

The presence of characteristic histopathological lesions are the basis of diagnosis. These lesions are found in the lung tissues, central nervous system tissues, and lymphoid tissues. Intranuclear and intracytoplasmic inclusion bodies are found along with the lesions.

10. There are vaccines available to prevent individuals from becoming infected with dolphin morbillivirus.

Answer: True

Three vaccines are commonly used: a modified live virus canine distemper vaccine, a killed canine distemper vaccine, and a subunit canine distemper vaccine. In recent years, the U.S. Navy Marine Mammal Program, in collaboration with industry and academic partners, has developed a vaccine that incorporates the fusion and hemagglutinin genes of dolphin morbillivirus.
