This study developed altered Coccidia strains to protect chickens from disease, reducing the need for antibiotics in animal feed. This approach minimizes antibiotic resistance and side effects in humans.
Area of Science:
- Veterinary Parasitology
- Microbiome Research
- Food Safety
Background:
- Gut microbiome is crucial for health; antibiotics disrupt its balance, leading to disease.
- Coccidiosis causes gastrointestinal inflammation and antibiotic additives in animal products pose human health risks.
Purpose of the Study:
- To develop nonpathogenic, immunogenic Coccidia strains to protect food animals.
- To reduce antibiotic use in animal agriculture and mitigate human health risks.
Main Methods:
- Diverse Coccidia species were altered through purification and serial passage.
- Chicks were immunized with altered strains and challenged with virulent Coccidia.
Main Results:
- Altered E. tenella and E. necatrix lacked sporocysts, containing free sporozoites.
- Immunized chicks showed enhanced protection, higher weight gain, and antibody titers (p < 0.05).
Conclusions:
- Induced altered Coccidia strains offer protection against coccidiosis.
- This strategy presents a novel method to minimize antibiotic use in food animals.
