What Is Infectious Coryza in Chickens?
Infectious coryza is an acute upper respiratory disease caused by Avibacterium paragallinarum. Chickens are the natural host, and birds from 4 to 12 weeks of age and laying hens can be highly susceptible. Transmission occurs mainly through respiratory droplets, contaminated feed and water, and contact with infected or carrier birds.
Key point: Avibacterium paragallinarum is environmentally fragile, but carrier and recovered birds can maintain infection within a flock. Vaccination, biosecurity and age-group separation are central to prevention.
Clinical Signs And Production Impact
Infectious Coryza Can Reduce Health and Production
Infectious coryza can spread rapidly through a susceptible flock and cause upper respiratory disease, facial swelling, discharge, reduced feed intake and production loss.
01
Facial Swelling and Nasal Discharge
Swelling around the face and wattles, nasal discharge and conjunctivitis are common field signs.
02
Respiratory Distress
Sneezing, labored breathing and upper respiratory inflammation can impair flock performance.
03
Ear and Neurological Complications
Severe cases may involve caseous ear exudate, torticollis, cerebellar edema and intracranial lesions.
04
Egg Production Loss
Laying hens may show reduced egg production and prolonged recovery after an outbreak.

Why Infectious Coryza Serotype Coverage Matters
Avibacterium paragallinarum is commonly grouped into serotypes A, B and C. Cross-protection between serotypes is limited, so vaccine selection should reflect circulating serotypes and farm history.
Product communication point: Confirm the target country, flock type, age, previous outbreaks, serotype information, production stage and whether a standalone or combined vaccine is required.
Strain and Serotype Reference
Infectious Coryza Serotypes A, B and C
Serotype prevalence varies by region and flock history. Broad serotype coverage supports programs where local field information is incomplete.
| Serotype | Field Relevance | Cross-protection | Selection Note |
|---|---|---|---|
| A | Common in many poultry markets | Limited against B and C | Include when serotype A is detected or suspected |
| B | Important in some regional outbreaks | Limited against A and C | Use market surveillance and farm history |
| C | Prevalence varies by region | Limited against A and B | Consider trivalent coverage when local data are uncertain |

Core Technology
WOLLVAC Infectious Coryza Vaccine Technology Highlights
WOLLVAC vaccine directions focus on antigen quality, formulation safety, stable immune response and practical farm use.
01
Endotoxin Control
Processing targets levels at or below 10 EU/mL to reduce endotoxin-related stress.
02
Composite Oil Adjuvant
Imported composite oil adjuvant supports stable formulation and antibody response.
03
Low Viscosity
Viscosity below 30 cP supports smooth injection and reduced vaccination stress.
04
Th1 Immune Pathway
The adjuvant system supports Th1-related immune pathways important for bacterial antigens.
05
Trivalent Serotype Coverage
A, B and C coverage addresses limited cross-protection between coryza serotypes.
06
Purified Subunit Antigen
Purified tandem subunit protein is specified at at least 90 percent purity.
07
High Antigen Content
Each A, B and C component is specified at at least 300 micrograms per mL.
Immunization Strategy
Infectious Coryza Control Requires Vaccination and Biosecurity
A practical program combines suitable vaccination, clean sourcing, flock management, monitoring and qualified veterinary guidance.
01
Primary Immunization
Primary vaccination establishes immune memory but may produce a limited initial antibody response.
02
Booster Immunization
A second dose can rapidly increase antibody levels and support longer protection in layer flocks.
03
Pullet Preparation
Pullets should receive an inactivated coryza vaccine before sale, with history communicated to the buyer.
04
Breeder Program
Breeder flocks may require three immunizations to support flock and maternal antibody protection.
05
All-In All-Out Management
Avoid mixing age groups and use all-in/all-out management to reduce circulation.
06
Ventilation and Disinfection
Maintain ventilation, suitable stocking density and regular environmental disinfection.
Dose, timing and administration must follow the registered label, local regulations and qualified veterinary guidance.
