Correct Answer - Option 4 : Pasteurella multocida

The correct answer is Pasteurella multocida.

• Fowl cholera is a septicemic disease caused by Pasteurella multocida.
  • It affects a variety of domesticated and wild birds.
  • This is a highly contagious disease.
  • It causes high morbidity and mortality resulting in great economic losses, especially in large industrial-type poultry complexes.
  • It usually occurs as an acute disease, but chronic infections can also occur in some outbreaks.
  • It is seen worldwide and was one of the first infectious diseases to be recognised by Louis Pasteur in 1880.
  • The disease can range from acute septicaemia to chronic and localised infections and the morbidity and mortality may be up to 100%.
  • The route of infection is oral or nasal with transmission via nasal exudate, faeces, contaminated soil, equipment, and people.
  • The incubation period is usually 5-8 days.
  • The bacterium is easily destroyed by environmental factors and disinfectants but may persist for prolonged periods in soil.
