Oxidative Stress and Intestinal Transcriptome Changes in Clostridium perfringens Type A-Caused Enteritis in Deer

Area of Science:

• Veterinary Medicine
• Animal Science
• Microbiology

Background:

• Clostridium perfringens type A is a primary cause of enteritis in deer, leading to significant economic losses.
• The bacterium produces toxins that inflict intestinal damage in affected animals.

Purpose of the Study:

• To investigate the molecular mechanisms underlying Clostridium perfringens type A-induced enteritis in fallow deer.
• To identify key gene expression patterns and molecular responses in deer intestines following C. perfringens type A infection.

Main Methods:

• Transcriptome analysis was conducted using an intestinal circulation model in fallow deer.
• Protein levels of immunoinflammation markers were quantified using ELISA.
• Antioxidant capacity of the intestine was assessed to understand cellular responses.

Main Results:

• Transcriptome analysis indicated significant pathway enrichment in the hematopoietic system, oxidative stress, immune response, and intestinal tight junctions.
• Clostridium perfringens alpha-toxin was observed to enter the intestine, potentially activating TLR6 and leading to cytokine secretion, inflammasome activation, oxidative stress, and intestinal damage.

Conclusions:

• This research provides a detailed transcriptomic understanding of gene expression in deer enteritis caused by C. perfringens type A.
• The findings offer a foundation for developing therapeutic strategies to combat deer enteritis.
