Coccidia exhibit a high degree of host species specificity, and cross-infections, even between relatively closely related species such as sheep and goats, do not generally occur. This book chapter describes the coccidia of sheep, coccidial life cycle, pathology, pathogenesis and pathophysiology,...

Large lungworms can cause clinical disease and occasional mortality, whereas infections with small lungworms are often subclinical. Although several species of small lungworm have been isolated from small ruminants, this book chapter describes the most commonly described in the scientific...
