This document discusses practical approaches for diagnosing viral diseases in poultry, including clinical diagnosis, rapid field diagnostic tests, serological diagnosis, molecular diagnosis, and isolation/characterization. Clinical diagnosis is based on case history, clinical signs, examination of live/dead birds, and gross lesions. Rapid field tests can detect viruses but require high viral titers. Serological tests detect antibodies but have delays. Molecular diagnosis using PCR technologies can sensitively and specifically detect pathogens. The document emphasizes that clinical signs alone are not confirmatory and that multiple diagnostic approaches should be used to accurately diagnose poultry viral diseases.
Avian encephalomyelitis (AE) is a viral disease of the CNS of young chickens, turkeys, Japanese quail, pheasants, and pigeons. Turkeys are less susceptible to natural infection and generally develop a milder clinical disease than chickens. Ducklings and guinea fowl are susceptible to experimental infection
A good poultry health management is an important component of poultry production. Infectious disease causing agents will spread through a flock very quickly because of the high stocking densities of commercially housed poultry.
For poultry health management to be effective a primary aim must be to prevent the onset of disease or parasites, to recognize at an early stage the presence of disease or parasites, and to treat all flocks that are diseased or infested with parasites as soon as possible and before they develop into a serious condition or spread to other flocks. To be able to do this it is necessary to know how to recognize that the birds are diseased, the action required for preventing or minimising disease and how to monitor for signs that the prevention program is working.

Poultry disease diagosis
1.
2. Practical approaches for diagnosis of poultry
viral diseases
1. Clinical diagnosis
2. Rapid field diagnostic tests
3. Serological diagnosis (HI& ELISA)
4. Molecular diagnosis (PCR technologies)
5. Isolation and characterization (the gold standard methods limited to
reference laboratories)
3. 1. Clinical diagnosis
Clinical diagnosis was made on the basis of:
1. Case history.
2. Clinical signs.
3. External examination of live and dead, birds.
4. Gross pathological lesions of the dead and sick bird
5. Are clinical symptoms enough for confirmative
diagnosis of infection?
Symptoms are not confirmative, for example:
1. HPAI can share Velogenic NDV in high mortality number (90-100%),
nervous and/or digestive signs, Haemorrhages of proventricular glands and
haemorrhages of Peyer's patches.
2. LPAI can share IB in respiratory signs (caseous plugs) and kidney affection
or other respiratory pathogens that affect egg production and quality.
3. Don’t forget presence of mixed (AI with IB or NDV ) and subclinical
infection (IBDV- CAV-AE-REO).
4. So you need quick accurate tool to confirm and differentiate your suspected
diagnosis.
6. How to confirm your clinical diagnosis?
Range of Detection of AIV in a Flock (Unvaccinated)VirusLevel
Days Post-Infection
0 7 14 21 28
Rapid field tests
B. Antibody detection
rRT-PCR
Virus Isolation
HI (IgG)
ELISA (IgG)
A. Direct Virus detection
7. 1. Limitation of rapid antigen tests
1. Most useful for sick and dead birds (acute)
2. Time of application: at beginning of clinical signs (high titter of the
virus) in case of AI up to 5 days after beginning of clinical signs.
3. AI detection limit: 103.5-104.5 EID50/ML.
4. Sensitivity depend on the titter of virus shedding, so it confirm
positive result not negative result.
5. The tests should only be interpreted on a flock basis and not as an
individual bird test (up to10 test/house).
6. Preliminary tests: so need further tests---------(Molecular diagnosis-
isolation).
8. 3. Limitation of Serological diagnosis
(B. Antibody detection)
Ex. HI& ELISA.
1. Vaccination programs.
2. Disease monitoring
• Baseline establishment
• Experience in interpretation
• Delayed Action.
• Multiple reagents and in some cases live antigens
• ELISA Reader and High skillful technical
Diagnosis can only be established when one combines VI
scores with clinical symptoms and isolation of the pathogen
and/or confirmation testing with PCR.
9. 4. Molecular Diagnosis
(A. Virus detection)
PCR technologies
• Detecting the nucleic acids of the pathogens.
• High sensitivity.
• High specificity.
• Samples can be the environmental samples and biological materials.
10. PCR application
Screen the most concerned pathogens.
Identify the pathogen from the common clinical sign (ex. Differential diagnosis for
respiratory clinical signs).
Monitoring the pathogen before the vaccination (subclinical infection with
IBDV, AIV H9 and CIAV, Mycoplasma).
Detect the pathogen from weak birds prior the ELISA antibody result turns to be
positive.
Enhancing biosecurity.
11. The PCR Lab that you know
