This document contains images and descriptions of various infectious diseases that affect sheep and goats, including parasitic, viral, bacterial, and fungal diseases. Parasitic diseases featured include mange, ticks, cutaneous myiasis, nasal bot flies, and various types of worms. Viral diseases shown are bluetongue, foot-and-mouth, sheep pox, and contagious ecthyma. Bacterial infections presented involve anthrax, black disease, salmonellosis, listeriosis, tetanus, caseous lymphadenitis, brucellosis, and dermatophilosis. Fungal ringworm is also included. For each disease, relevant clinical signs, lesions, microorgan
