Identifying Zoonotic Diseases Transmitted by Vectors

1. Understanding Zoonotic Diseases: Zoonotic diseases are illnesses that are transmitted from animals to humans. These diseases can be spread through various means, including direct contact, environmental exposure, and via vectors.

2. Identifying Vectors: Vectors are organisms that transmit pathogens from one host to another. Common vectors include mosquitoes, ticks, and fleas.

3. Analyzing the Options:

   • a. Lyme disease: Caused by the bacterium Borrelia burgdorferi, it is transmitted to humans through the bite of infected black-legged ticks, making it a vector-borne zoonotic disease.
   • b. Q-Fever: Caused by Coxiella burnetii, typically transmitted from animals like cattle and goats, but not by a vector.
   • c. Anthrax: Caused by the bacterium Bacillus anthracis and is not transmitted by vectors; it is primarily associated with handling infected animal products.
   • d. Avian influenza: While it is a zoonotic disease, it is not transmitted by vectors but rather through direct contact with infected birds.

4. Conclusion: Among the options provided, Lyme disease (option a) is the only zoonotic disease that is specifically transmitted by a vector (ticks).

Final Answer

a. Lyme disease is an example of a zoonotic disease transmitted by a vector.
