In India, state programmes schedule black quarter vaccination of cattle:
D. Before the monsoon
Blackquarter and HS outbreaks follow the monsoon, so vaccination is given before it, and in outbreaks the in-contact herd is vaccinated as well. Very young calves are not the main target group, as disease peaks between 6 months and 2 years.
A cow is found dead with dark, unclotted blood oozing from the nostrils and anus and rapid bloating. What should the veterinarian do first?
B. Collect a peripheral blood smear without opening the carcass
These signs suggest anthrax. Opening the carcass lets vegetative cells sporulate and contaminate soil for decades, so an ear-vein smear stained with polychrome methylene blue is taken first. Burying without a sample loses the diagnosis and the notification.
In an anthrax outbreak, a farmer asks to give long-acting oxytetracycline to all in-contact cattle on the same day as the live spore vaccine. What is the correct advice?
C. Do not overlap them, because the antimicrobial kills the live vaccine strain
The Sterne vaccine is a live spore vaccine, and antimicrobials given around vaccination kill it and prevent immunity; national instructions set the interval between treatment and vaccination. Vaccination is the main tool in outbreaks, not a contraindication.
Under India's National Animal Disease Control Programme, brucellosis vaccination with strain 19 is given to:
A. Female bovine calves aged 4-8 months, once in a lifetime
NADCP vaccinates female cattle and buffalo calves at 4-8 months, once. S19 in pregnant animals can cause abortion, and in adults can cause persistent antibody that confuses testing.
Which stain is used on placental cotyledon smears to demonstrate Brucella?
C. Modified Ziehl-Neelsen (Stamp's) stain
Brucella resists decolorisation with weak acid in the modified ZN (Stamp) method and appears as red coccobacilli in clumps. Coxiella and Chlamydia also stain with MZN, so culture or PCR confirms.
The mallein test for glanders is performed by injecting mallein:
B. Intradermally into the lower eyelid (intradermo-palpebral)
The intradermo-palpebral mallein test is read for swelling of the eyelid, conjunctivitis and purulent discharge at 24-48 hours. The caudal fold is used for tuberculin testing in some countries.
Sulphur granules in pus from actinomycosis lesions are:
A. Colonies of the organism surrounded by club-shaped deposits
The yellow granules are bacterial colonies with radiating club-shaped deposits (the Splendore-Hoeppli phenomenon); crushed and Gram-stained, they show Gram-positive filaments.
Penicillin is ineffective against mycoplasmas because they:
A. Lack a cell wall
Beta-lactams act on cell-wall synthesis, which mycoplasmas do not have. Tetracyclines, macrolides and fluoroquinolones are the classes used where treatment is permitted.
Which feature best distinguishes anaplasmosis from babesiosis in cattle?
C. Absence of haemoglobinuria in anaplasmosis
Anaplasma-infected red cells are removed extravascularly, so there is anaemia and jaundice without red urine; babesiosis causes intravascular haemolysis with haemoglobinuria. Anaplasmosis is severe in adults, not calves.
Favus of the comb and wattles in chickens is caused by:
B. Microsporum gallinae
M. gallinae causes white scaly crusts on the comb (favus). Aspergillus causes respiratory disease and Candida causes crop mycosis (thrush).
This plan follows where our questions actually fall, so the time goes where the marks are likely to be. It is our reading of the syllabus, not the exam body's weighting.
Read the manual chapters for these first and do every worked question you can find on them.
Aim for one sitting per unit, then mixed questions across them.
Learn the definitions, classifications and standard numbers; these units are more often recalled than worked.
Come back to these after a first pass, untimed, and read every explanation, including for the options you rejected.
Do these early in revision so they are fast on the day.
