Broiler chicken distal jejunum microbial communities are more responsive to coccidiosis or necrotic enteritis challenge than dietary anti-interleukin-10 in a model using Salmonella Typhimurium- Eimeria maxima- Clostridium perfringens coinfection.

ABSTRACT: Dietary anti-interleukin (IL)-10 antibodies may protect broiler performance during coccidiosis by inhibiting Eimeria host-evasion pathways; however, anti-IL-10's effects on microbial communities during coccidiosis and secondary Clostridium perfringens (necrotic enteritis) challenge is unknown. The study objectives were to assess the jejunal microbiota of broilers fed anti-IL-10 during E. maxima ± C. perfringens challenge. Two replicate studies using Ross 308 chicks placed in wire-floor cages (32 cages/ replicate study; 20 chicks/ cage) were conducted, with chicks assigned to diets ± 0.03% anti-IL-10 for 25 d. In both replicate studies, challenge-designated chicks were inoculated with 1 × 10⁸Salmonella Typhimurium colony forming units (CFU) at placement. On d14, S. Typhimurium-in
