Camelidae and Cervidae Ulcerative Pododermatitis – NAVLE Study Guide

Overview and Clinical Importance

Ulcerative pododermatitis is an inflammatory and infectious condition affecting the foot pads and interdigital skin of camelids (llamas, alpacas) and the hooves of cervids (elk, deer). In camelids, the disease presents as ulcerative lesions of the soft foot pads, while in cervids, it manifests as treponeme-associated hoof disease (TAHD), causing severe lameness and hoof deformities. Understanding the unique foot anatomy of these species and the distinct etiologies is critical for NAVLE success.

This condition represents a significant welfare concern as it causes pain, lameness, decreased productivity, and in severe cases, can be life-threatening. Environmental factors, particularly wet and unsanitary conditions, play a crucial role in disease development for both species groups.

Comparative Foot Anatomy

Camelid Foot Anatomy (Llamas and Alpacas)

Camelids belong to the suborder Tylopoda (Greek for "padded foot"), which distinguishes them from other ungulates. Unlike cattle, horses, or sheep, camelids do NOT have hooves. Their feet have unique anatomical features:
