Africa's poultry sector is experiencing rapid growth, driven by increasing demand for affordable animal protein, expanding commercial farming, and government initiatives to strengthen food security. However, infectious diseases remain one of the biggest challenges limiting poultry productivity across the continent. Disease outbreaks result in high mortality, reduced egg production, poor feed conversion, lower hatchability, and substantial economic losses for farmers.
Many poultry diseases share similar clinical signs, making accurate laboratory diagnosis essential for effective treatment and disease control. Modern molecular diagnostic techniques, particularly multiplex real-time PCR (qPCR), provide rapid and highly sensitive detection of multiple pathogens from a single sample, enabling veterinarians and producers to respond before outbreaks spread.
Several factors contribute to the high prevalence of poultry diseases across African countries:
Strengthening disease surveillance through molecular diagnostics is becoming increasingly important to protect poultry health and improve farm profitability.
Causative Agent: Newcastle Disease Virus (NDV)
Newcastle Disease is one of the most devastating poultry diseases in Africa and remains endemic in many regions.
Causative Agent: Influenza A Virus (H5, H7, H9 and other subtypes)
Highly Pathogenic Avian Influenza (HPAI) causes significant economic losses due to rapid transmission and mandatory control measures.
Early molecular diagnosis is critical for outbreak containment.
Causative Agent: Infectious Bronchitis Virus (IBV)
IB primarily affects the respiratory tract and reproductive system.
Causative Agent: Gallid Herpesvirus-1
ILT causes severe respiratory disease, particularly in layer and breeder flocks.
Secondary bacterial infections are common.
MG is responsible for chronic respiratory disease and significantly affects flock productivity.
MS affects both respiratory and musculoskeletal systems.
Fowl Adenovirus causes Inclusion Body Hepatitis, especially in young broilers.
ORT commonly occurs alongside viral respiratory infections.
Causative Agent: Salmonella species
Salmonella affects both poultry production and food safety.
Many poultry outbreaks involve multiple pathogens simultaneously. Birds infected with one organism are often more susceptible to secondary infections, resulting in greater production losses.
Common combinations include:
Testing for only a single pathogen may overlook the true cause of disease, making multiplex molecular diagnostics an important tool for comprehensive flock health assessment.
Compared with conventional diagnostic methods, multiplex qPCR offers several important benefits:
For the highest diagnostic accuracy, laboratories commonly test:
Proper sample collection, storage, and transportation are essential for reliable molecular results.
As poultry production continues to expand across Africa, rapid disease detection and effective surveillance will play an increasingly important role in protecting flock health and improving productivity. Integrating multiplex real-time PCR into routine veterinary diagnostics enables earlier detection of infectious diseases, faster outbreak response, and better-informed disease management strategies.
Investment in advanced molecular diagnostics will help reduce economic losses, strengthen food security, improve animal welfare, and support the sustainable growth of Africa's poultry industry.

Designed for veterinary laboratories, research institutions, and animal health professionals, ANIDX™ panels deliver rapid, sensitive, and reliable detection of multiple pathogens in a single assay, enabling faster clinical decisions and more effective disease surveillance.
Newcastle Disease remains one of the most economically significant poultry diseases across many African countries, although Avian Influenza outbreaks can also cause severe losses.
Multiplex PCR detects several pathogens simultaneously with high sensitivity, providing faster and more comprehensive results than conventional diagnostic methods.
Tracheal, oropharyngeal, and cloacal swabs are commonly used for live birds, while tissue samples such as lung, liver, spleen, and kidney are preferred during post-mortem investigations.
Yes. Co-infections are common in commercial poultry and often result in more severe disease and greater production losses.
