Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Anthrax is a fatal disease which commonly effects humans and cattle. It is caused by spores of bacteria Bacillus anthracis. These spores remain in soil for decades and are also found in bloody discharges of infected animals and can spread to other animals easily.

Clinical signs depend on species of cattle effected. If infection occurs through mouth or nose the symptoms are shown immediately and death occurs rapidly. If infection occurs through skin there will not be acute symptoms but later becomes generalized. If infection is less acute symptoms may be having difficulty in breathing, tremble, collapse and die. Nearby death blood oozes from openings of animal. When infection is localized to throat area, the neck swells and bloody discharge comes from mouth. 

So, the correct answer is 'Anthrax'.

  3. Cane Planter

  4. Winnowers
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • Lactometer is an instrument which is used to check the purity of milk on the basis of density/buoyancy. Adulteration of water or the addition of any compound in the milk decreases the density. Threshers, cane planter and winnowers are the instrument used in agriculture. 

  • Thus, the correct option B.

  2. Anthrax

  3. Foot and mouth disease

  4. Cholera
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Rinderpest disease was characterized by necrosis and erosions in the gastrointestinal tract that resulted in severe diarrhoea and dehydration. The animal would at first become pyrexic, dull and depressed. Oral lesions included ulcers, vesicles and erosions on the tongue and oral mucosa, causing ptyalism, smacking of the lips and bruxism due to pain. There was also very commonly diarrhoea or blood and mucous. Diarrhoea and breath would usually have a foul odour. Generally the animal would be weak, lethargic and be reluctant to eat. There may have been signs of weight loss or reduced weight gain. There may have been ocular signs such as excess lacrimation, blepharospasm and reddened conjunctiva. The animal may have also exhibited respiratory distress with dyspnoea, tachypnoea, coughing and nasal discharge. Global Rinderpest Eradication Programme (GREP) succeeded in its goal in 2011 to eradicate this disease globally. 
Therefore, the correct answer is option A.
