Step 1: Understanding the Concept:
This question matches veterinary terms and disease synonyms with their corresponding diagnostic categories, pathogens, or clinical entities.
Detailed Explanation:
Let us analyze each pair:
- A. Dry cow therapy: Refers to the administration of long-acting intramammary antibiotic infusions to dairy cows at the start of their dry period. This is a cornerstone strategy for treating existing subclinical mastitis and preventing new infections, matching with IV. Mastitis.
- B. Red Water Disease: Bovine babesiosis, caused by the intraerythrocytic protozoan I. Babesia bigemina, is commonly known as redwater because intravascular hemolysis leads to hemoglobinuria, which colors the urine red.
- C. Turning sickness: An atypical, chronic form of East Coast Fever caused by II. Theileria parva. It occurs when parasitized lymphoblasts sequester in the brain capillaries, causing thrombosis, infarction, and neurological signs such as circling or "turning."
- D. Ragpicker disease: Historically, anthrax, caused by Bacillus anthracis, was known as ragpicker's disease or woolsorter's disease. This name arose because people who handled contaminated animal fibers or rags contracted the inhalation or cutaneous form of III. Anthrax.
Therefore, the correct matches are: A-IV, B-I, C-II, D-III.
Step 2: Final Answer:
The matching corresponds to Option (A).
