Question

Match List I with List II:
List I (Arthropod)
A. Hyalomma anatolicum anatolicum
B. Rhipicephalus microplus
C. Haemphysalis spinigera
D. Rhipicephalus appendiculatus
List II (Parasite/ Disease transmitted)
I. Babesia bigemina
II. Theileria equi
III. Bovine Tropical Theileriosis
IV. Kyasanur Forest Disease
Choose the correct answer from the options given below:

• A. A-III, B-I, C-IV, D-II
• B. A-II, B-I, C-III, D-IV
• C. A-III, B-I, C-II, D-IV
• D. A-II, B-III, C-IV, D-I

Hint:

Always associate Boophilus/Rhipicephalus microplus with Babesia bigemina, and Hyalomma anatolicum with Bovine Tropical Theileriosis to quickly eliminate incorrect matches in tick-borne disease questions.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Ticks are highly significant vectors of zoonotic and veterinary pathogens.
They transmit a wide array of protozoa, rickettsiae, bacteria, and viruses.
Each tick genus and species has specific ecological niches and biological relationships with the pathogens they transmit.

Step 2: Detailed Explanation:
Let us analyze the matches step-by-step:
1. Hyalomma anatolicum anatolicum (A):
This hard tick is the primary vector for Theileria annulata, the causative protozoan of Bovine Tropical Theileriosis in Asia and the Mediterranean.
Thus, A matches with III.
2. Rhipicephalus microplus (B):
This single-host tick is well known as the primary vector for Babesia bigemina (which causes bovine babesiosis or red water fever) and Babesia bovis.
Thus, B matches with I.
3. Haemphysalis spinigera (C):
This tick is the primary forest-dwelling vector of the flavivirus causing Kyasanur Forest Disease (KFD), a highly zoonotic hemorrhagic fever endemic to parts of India.
Thus, C matches with IV.
4. Rhipicephalus appendiculatus (D):
Known as the brown ear tick, it is famous for transmitting Theileria parva (East Coast Fever).
However, species of Rhipicephalus are also implicated in the transmission of equine piroplasmosis caused by Theileria equi.
Matching with the remaining option, D corresponds to II.
Combining the matches:
A-III, B-I, C-IV, D-II.

Step 3: Final Answer:
The correct matching sequence is A-III, B-I, C-IV, D-II.
Therefore, the correct answer is option (A).
