Fowl Pox

Causes: caused by viruses of the family Poxviridae and the genus Avipoxvirus.

Signs
Warty, spreading eruptions and scabs on comb and wattles.
Caseous deposits in mouth, throat and sometimes trachea.
Depression.
Inappetance.
Poor growth.
Poor egg production.

Prevention
By vaccination (except canary). Chickens well before production. Turkeys by thigh-stick at 2-3 months, check take at 7-10 days post vaccination. There is good cross-immunity among the different viral strains.
Treatment
Flocks and individuals still unaffected may be vaccinated, usually with chicken strain by wing web puncture. If there is evidence of secondary bacterial infection broad-spectrum antibiotics may be of some benefit.
Infectious Bronchitis

Causes The cause is a Coronavirus that is antigenically highly variable; new sero-types continue to emerge. About eight sero-groups are recognised by sero-neutralization. Typing by haemagglutination-inhibition is also used. These differences are due to structural differences in the spike proteins (S1 fraction).
Signs
Depression.
Huddling.
Loss of appetite.
Coughing, gasping, dyspnoea.

Wet litter.
Diarrhoea.
Diuresis.
Treatment
Sodium salicylate 1gm/litre (acute phase) where
