What Is Infectious Bronchitis in Chickens?

Infectious Bronchitis (IB) is an acute and highly contagious viral disease in chickens caused by Infectious Bronchitis Virus (IBV), an avian coronavirus. According to the affected tissue and viral strain, IB can appear as respiratory type, renal type or reproductive / proventricular-related disease.

In commercial poultry production, IBV can cause coughing, sneezing, tracheal rales, open-mouth breathing, kidney swelling, reduced egg production, egg quality problems and irreversible reproductive tract damage in young birds.

Because IBV has many serotypes and cross-protection between different strains is limited, vaccine selection should consider local circulating genotypes, farm disease history, bird age and the existing vaccination program.

Key point: IB vaccine selection should not rely only on traditional Mass-type strains. For markets where QX-like strains dominate, QX antigen matching becomes a key product-selection factor.

Clinical Signs And Production Impact

IBV Can Damage the Respiratory, Renal and Reproductive Systems

Infectious Bronchitis is not only a respiratory disease. Depending on the strain and infection stage, it may also cause severe kidney damage and long-term reproductive losses.

Respiratory Type

Sudden coughing, sneezing, tracheal rales and open-mouth breathing may occur. Chicks can be more severely affected.

Renal Type

Chickens may show watery white diarrhea, dehydration and swollen pale kidneys with urate deposition.

Reproductive Type

Infection during early growth may cause permanent oviduct damage, false layers and reduced egg production.

Egg Quality Loss

IBV may lead to soft-shelled, misshapen or sandpaper-like eggs and watery egg whites in laying hens.

Clinical examples: swollen kidneys with bleeding points and fallopian tube cysts associated with IBV impact.

IBV may affect respiratory performance, kidney health and reproductive productivity in chickens.

Why IBV Strain Matching Matters

IBV has many serotypes, and the predominant strains may vary by region and time. The supplied material indicates that QX genotype field isolates account for more than 70%, while 4/91 remains consistently detected at about 4%.

Traditional Mass-type vaccine strains such as H120, H52, M41, Ma5, W93 and 2886 may provide limited protection against currently dominant field strains when antigen matching is poor.

For this reason, WOLLVAC emphasizes a practical IB vaccine strategy built around early respiratory tract immunity, QX-related antigen matching, live vaccine priming and inactivated vaccine boosting for sustained antibody response.

Product communication point: When customers ask for IB vaccine, first confirm country, circulating genotype, bird type, farm age structure, respiratory signs, kidney lesions, egg production problems and current vaccination program.

Product Selection Guide

How to Choose an IB Vaccine Direction

Select IB vaccine products according to local IBV genotype, clinical type, bird age, vaccination history, flock production stage and co-infection pressure.

Field Situation

WOLLVAC IB Vaccine Technology Highlights

WOLLVAC IB vaccine solutions are designed around strain matching, live-inactivated combination strategy, adjuvant technology, stability and impurity reduction.

Advantageous Strain Combination

Live vaccine antigen combination includes H120, QX and 4/91 strains, supporting broader IBV program communication.

QX-Type Inactivated Antigen

Inactivated vaccine uses QX-type epidemic strain for improved antibody match against QX-type field pressure.

Imported Adjuvant System

French white oil and imported aqueous/oil emulsifier are combined with proprietary emulsification technology.

Low Viscosity & Transport Stability

Low viscosity supports easier injection. Supplied material notes heat resistance up to 40 C during long-distance transport for 5-7 days.

SPF Chicken Embryo Production

Live vaccine products are produced from SPF chicken embryos and contain purified antigens for product quality communication.

Ultrafiltration Concentration Process

Imported Millipore equipment and efficient microporous membranes help remove urate, non-specific proteins and other impurities, reducing immune side effects.

Immunization Strategy

IB Control Requires Early Immunity and Matched Vaccine Programs

IB prevention should combine early respiratory immunity, suitable strain selection, inactivated booster support and strict farm management.

Vaccinate Early

The supplied material emphasizes early IBV vaccination to induce respiratory tract immunity as early as possible.

Use Proper Route

For IBV live vaccine programs, the material recommends intranasal, ocular or aerosol delivery rather than relying on drinking water.

Combine Live and Inactivated

Live vaccines should be combined with inactivated vaccines to support rapid and sustained antibody response.

Consider Maternal Antibodies

Higher maternal antibody levels in 1-day chicks can be beneficial and may help protect the oviduct.

Match Local Strains

Choose IB vaccine direction according to local QX, 4/91, Mass or other genotype pressure.

Protect Production Performance

Focus on respiratory health, kidney lesions, egg production, egg quality and prevention of false layer syndrome.

Detailed dose, immune age, administration route and combination program should follow the official product label, local registration requirements and qualified veterinary guidance.

FAQ

Infectious Bronchitis Vaccine FAQ

Common questions from poultry farms, veterinarians, distributors and importers when selecting IB vaccines.

What is Infectious Bronchitis in chickens?

Infectious Bronchitis is an acute and highly contagious viral disease caused by Infectious Bronchitis Virus, an avian coronavirus. It may affect the respiratory system, kidneys and reproductive tract.

Why is QX genotype important for IB vaccine selection?

According to the supplied material, QX genotype accounts for more than 70% of listed field isolates. If the vaccine strain does not match the dominant field strain, protection may be limited.

Are Mass-type vaccines enough for current IBV pressure?

Traditional strains such as H120, H52, M41, Ma5, W93 and 2886 belong to the Massachusetts serotype. The supplied material indicates that they may offer limited protection against dominant QX-type field strains.

What antigens are included in the WOLLVAC IB live vaccine series?

The supplied material lists H120 strain, QX strain and 4/91 strain, each at >=10^3.5 EID50 / dose, as antigens for WOLLVAC Infectious Bronchitis live vaccine series.

What is the role of WOLLVAC QX-type IB inactivated vaccine?

The QX-type inactivated vaccine is designed for better antibody match against QX-type field pressure and can be used with live vaccine programs to support rapid and sustained antibody response.

Can IB vaccines be combined with ND, AI, EDS or other poultry vaccines?

Yes. WOLLVAC poultry vaccine directions include IB-related multivalent options such as ND + IB, ND + IB + AI, ND + IB + EDS and broader multivalent vaccine directions. Product selection should follow local registration status.

What administration route is recommended for IB live vaccines?

The supplied material emphasizes intranasal, ocular or aerosol delivery for IBV live vaccine programs. Final administration should follow the official product label and veterinary guidance.
