Acute or chronic contagious disease affecting domestic as well as wide range of wild birds
In acute form Septicemia condition with high mortality
The chronic form is also known as “WATTLE Cholera”
World-wide in distribution
Pasteurella multocida gram –ve, non motile, non spore forming
rod shaped bacteria. organism appears bipolar in shape while
stained with methylene blue or Giemsa stain
organism grows well on meat infusion broth enriched with peptone and avium serum
Gas –ve, Oxidase and Catalase test +ve organism killed with common disinfectant
and sunlight
Direct contact between susceptible birds and clinically affected or recovered carriers.
Rodents, and wild birds are sources of indirect infection. Contaminated
Feed bags, equipment, and the clothing of personnel may introduce infection into farm
Intraflock transmission is enhanced by handling birds for vaccination and weighing and by open
watering systems such as troughs and bell drinkers.
Per Acute: Death of large number of birds Acute : two type of manifestations
Pulmonary form : respiratory of distress appearing as sneezing, coughing and gasping, cyanosis prior to death
Septicemic form : fever, depression, anorexia, discharge from mouth and ruffled feathers along with diarrhea. Feces is watery in nature having whitish appearance initially followed by greenish coloration containing mucus
Chronic form: hyperemia and edema of comb and wattles Joint may be swollen. Swellings pit on
pressure. Affection of the joint may lead to lameness.
Mucoid discharge is noted in beak and nostrils.
Exudation may appear from eye (Conjunctivitis) or pharynx (pharyngitis).
Infection spread in the bone of head and or brain leading to in coordination, walking in circle and torticolis
Liver: Enlarged, focal area of coagulative necrosis, massive white or greyish necrotic foci resemble pin head
Heart: pin point hemorrhage in fat Intestine: viscid mucus, petechial
hemorrhage in duodenum Lungs: Pneumonic change Ovary: follicle appear flaccid, congestion,
egg peritonitis Joints: Swollen containing exudate Comb and wattle: swollen unilateral or
bilateral
