Question

Identify two diseases caused by bacteria in poultry

• A. Avian influenza, Infectious bronchitis
• B. Aspergillosis, Fowl Cholera
• C. Colibacillosis, Infectious coryza
• D. Rickets, Cage layer fatigue

Answer 1

The correct option is C Colibacillosis, Infectious coryza

Infections Coryza is usually acute and sometimes chronic, highly infectious disease of chickens, occasionally pheasants and guinea-fowl. Infectious Coryza is characterized by catarrhal inflammation of the upper respiratory tract, especially nasal and sinus mucosae. Infectious Coryza is caused by the bacterium Haemophilus paragallinarum and is seen in many countries especially in multi-age farms that are never depopulated.

Coli-septicaemia is the commonest infectious disease of farmed poultry. It is most commonly seen following upper respiratory disease (such as Infectious Bronchitis) or Mycoplasmosis. It is frequently associated with immunosuppressive diseases such as Infectious Bursal Disease Virus (Gumboro Disease) in chickens or Haemorrhagic Enteritis in turkeys, or in young birds that are immunologically immature. It is caused by the bacterium Escherichia coli and is seen worldwide in chickens, turkeys, etc.

So, the correct answer is 'Colibacillosis, Infectious coryza'.
