Abstract:
By means of local strains Bacteroides nodusus was reproduced experimentally a case of foot-rot with sheep. For the appearance and the development of the disease it was necessary, before the infection, to keep the sheep in damp and uncleaned from fecal impurities room. Besides that, of decisive importance was the scarification of the skin-horny junction in the interungular slit. The combination of Bacteroides nodusus with Spirohaeta penorta and Corynebacterium piogenes resulted in more serious changes in the infected hooves.
Insights
Experimental foot-rot in sheep was reproduced using Bacteroides nodusus. Infection required damp conditions and skin abrasions, with co-infections worsening hoof damage.
Area of Science:
- Veterinary Microbiology
- Animal Pathology
Context:
- Foot-rot is a significant disease affecting sheep worldwide.
- Understanding the pathogenesis of ovine foot-rot is crucial for effective treatment and prevention.
Purpose:
- To experimentally reproduce foot-rot in sheep.
- To identify key factors contributing to the development of ovine foot-rot.
- To investigate the role of specific bacterial agents in disease severity.
Summary:
- Experimental foot-rot was successfully induced in sheep using local strains of Bacteroides nodusus.
- Pre-infection conditions, including damp, unsanitary environments and interdigital skin scarification, were essential for disease development.
- Co-infection with Spirohaeta penorta and Corynebacterium piogenes led to more severe pathological changes in the hooves.
Impact:
- This study elucidates critical environmental and physical factors in Bacteroides nodusus-induced foot-rot.
- Findings provide insights into microbial interactions that exacerbate ovine hoof disease.
- Results can inform improved biosecurity and management strategies to control ovine foot-rot.
