Summary
Poultry production faces challenges from antibiotic restrictions, increasing necrotic enteritis (NE) caused by Clostridium perfringens. Developing alternative strategies and vaccines is crucial for controlling this costly disease.
Area of Science:
- Poultry Science
- Veterinary Medicine
- Microbiology
Background:
- Global restrictions on antibiotic growth promoters impact poultry health and production.
- Necrotic enteritis (NE), caused by Clostridium perfringens, is a major infectious disease in poultry, causing significant economic losses.
- There is a critical need for alternative strategies to manage and prevent NE.
Purpose of the Study:
- To review recent advancements in necrotic enteritis (NE) disease models.
- To summarize current knowledge on Clostridium perfringens pathogenesis and host immunity in poultry.
- To discuss risk factors and vaccine development for C. perfringens-associated NE.
Main Methods:
- Literature review of recent developments in NE research.
- Analysis of studies on Clostridium perfringens pathogenesis and host responses.
- Examination of research on NE disease models and vaccine strategies.
Main Results:
- Recent progress has been made in developing NE disease models.
- Understanding host- and environmentally related factors is key to NE development.
- Vaccination strategies against C. perfringens are under development.
Conclusions:
- Integrated management strategies are needed to control and prevent NE.
- Further research into C. perfringens pathogenesis and host immunity is essential.
- Development of reliable NE models and effective vaccines is a priority for poultry health.
