Definition of Tuberculosis in Poultry

Tuberculosis is a slowly spreading, chronic, granulomatous bacterial infection, characterized by gradual weight loss

Mycobacterium

avium

serovars

1 and 2 are the usual causes

Infected birds excrete the organism in their feces

Cadavers and offal may infect predators and cannibalistic

flockmates

Signs and Symptoms of Tuberculosis in Poultry

Signs

usually develop late in the infection when birds become thin and sluggish, and lameness may be seen

In chickens, granulomatous nodules of varying size are usually found in the liver, spleen, bone marrow, and intestine

Pharmacological Treatment of Tuberculosis in Poultry

Antituberculosis

drugs are not often used to treat chicken.

Ethambutol

Activity:

Brainstorming

What

are the prevention and control measures against Tuberculosis in Poultry??

Prevention and Control of Tuberculosis in Poultry

Depopulation

and good biosecurity practices including rodent control and screening

Addition of exotic birds to an exhibit should originate from a closed collection with no history of tuberculosis,

ie

, tuberculosis has not been reported previously or diagnosed on necropsy during the past 5 years

If no history is available, the birds should be quarantined or maintained in a separate exhibit away from the bird

aviary

Prevention and Control of Tuberculosis in Poultry

Cont.….

Therefore, it is recommended that endangered and valuable species be housed in individual exhibits to prevent transmission which is through ingestion of food or water contaminated with

M.

avium

ss

,

i.e

,

feces

from contagious birds

Infected poultry should be destroyed, and housing facilities thoroughly cleaned and disinfected using cresylic compounds

Key Points

Avian

tuberculosis is a chronic infectious disease characterized by the formation of granulomatous lesions in viscera, a progressive weight loss and death

The aetiological agent is Mycobacterium

avium

, a very resilient and acid-resistant

micro¬organism

Improved general sanitation has largely eliminated this infection
