What are the six major viral diseases of poultry?
Avian influenza Newcastle disease Avian rhinotracheitis Avian infectious bronchitis Avian infectious laryngotracheitis Avian fowlpox
Key points of Avian influenza? (6)
Orthomyxovirus Low pathogenic form much more common than high pathogenic Zoonotic Reportable Fecal-oral
Why is avian influenza such a big deal?
Zoonotic with high mortality for people
Key points of Newcastle disease? (6)
Paramyxovirus
Zoonotic - conjunctivitis
Velogenic viscerotropic - chickens bad, psittacines ok
Neurotropic velogenic - acute and fatal
Mesogenic - mortality and nervous signs in adults
Lentogenic - mild disease
Key points of avian rhinotracheitis? (4)
Paramyxovirus
Rapid transmission via fomites
Appetite decrease, voice loss, ocular and nasal discharge, egg production drop, thin-shelled eggs
Reportable
Key points of infectious bronchitis? (3)
Coronavirus
Most common resp dz of chickens
Some strains nephropathogenic
Key points of infectious laryngotracheitis? (3)
Herpesvirus
Highly contagious

Key points of chlamydiosis? (5)
Obligate intracellular
Rarely causes clinical signs in avian hosts
Watery droppings, weight loss, dehydration, ruffled feathers
Zoonotic
Reportable

Worldwide
Transferred in earthworms, slugs, snails
Gaping, dyspnea, head shaking, inappetence

Avian influenza (high and low pathogenicity)
Newcastle disease
Turkey rhinotracheitis
Avian infectious bronchitis
Avian infectious larygotracheitis
Mycoplasmosis (gallisepticum and synoviae)
