| + | **Raised crusts develop in the affected regions |
| + | *Diagnosis: |
| + | **Giemsa-stained smears from scabs reveal branching filaments containing zoospores |
| + | **Immunofluorescence |
| + | **Scab material can be cultured on blood agar at 37 degrees centigrade, 2.5-10% carbon dioxide for 5 days |
| + | **Zoospores can be cultured |
| + | **After incubation, colonies are yellow and haemolytic (after 48 hours); they later become rough and yellow, and gain a mucoid appearance |
| + | **No growth on Sabouraud dectrose agar |
| + | *Clinical infections: |
| + | **Infection usually confined to epidermis |
| + | **Dermatophilosis |
| + | **Disease most prevalent in young animals |
| + | **Damage to the skin predisposes to infection; blood-sucking insects also thought to be involved in transmission |
| + | **Lesions after heavy rainfall predominantly affect dorsum of farm animals |
| + | **Papules, serous, exudative matting of hair, raised crusty scabs |
| + | **Scab formation more prominent in sheep and cattle than in horses |
| + | **Lesions may resolve within weeks if dry weather, or may progress |
| + | *Treatment: |
| + | **Parenteral antibiotics e.g oxytetracycline, pr penicillin-streptomycin combinations |
