Ovine and Caprine Enteritis Study Guide
Overview and Clinical Importance
Neonatal enteritis represents one of the most significant causes of morbidity and mortality in lambs and kids during the first month of life. The etiology is multifactorial, involving interactions between host susceptibility, environmental factors, nutritional status, and various infectious agents. Understanding the pathophysiology, clinical presentation, and management of these enteric diseases is essential for NAVLE success and clinical practice.
The major pathogens causing infectious enteritis in small ruminants include viral agents (rotavirus, coronavirus), bacterial pathogens (enterotoxigenic E. coli, Salmonella spp.), and protozoal parasites (Eimeria spp., Cryptosporidium parvum, Giardia duodenalis). Mixed infections are common and often result in more severe disease.
