Dermatological disease:
Approach to dermatological and oral disease
History | § What type of pigs? Finishers? Breeders? Piglets? § Scale of farm? § How many pigs affected? § What aged pigs affected? § What clinical signs have they noticed? Where? o Scabs? o Snout? – snout vesicles = FMD o Oral lesions? – vesicles in oral cavity = vesicular stomatitis o Hypersalivation? - SVD o Feet? – hoof lesions/sloughing = FMD, interdigital/coronary band vesicles = vesicular stomatitis, granulation tissue on feet = vesicular exanthema o Mammary glands? – vesicular stomatitis o Red diamond shaped lesions = erysipelas § Any other clinical signs? – lameness = FMD, SVD, vesicular stomatitis, neurological signs = SVD § Any deaths? – erysipelas § Any abortions? – erysipelas § Any recent changes in diet or management? § Vaccination protocol? |
Investigations | § If lame – FMD, VS, SVD likely – contact APHA § Clinical exam o TPR – pyrexic = FMD, SVD, erysipelas § Sample vesicular fluid – ELISA or PCR – FMD or SVD |
Treatment | § FMD – no treatment, destroy cadavers, bedding and animal products § Erysipelas - penicillin |
Infectious causes of skin disease | § FMD: o NOTIFIABLE DISEASE – contact APHA o Transmission § Direct contact: ingestion of animal products, direct contact with infected wildlife, wind § Indirect via fomites, e.g. contaminated clothing/footwear, vet equipment, vehicles o Control: vaccination in endemic areas (but 7 serotypes), don’t feed waste meat products to pigs § Vesicular stomatitis o NOTIFIABLE DISEASE – contact APHA o § SVD o NOTIFIABLE DISEASE – contact APHA o Control: cull diseased, susceptible and in-contact animals, no vaccine § Vesicular exanthema – deep lesions with granulation tissue formation on feet § Erysipelas o Control: vaccination (6m booster) o Clinical signs: abortions/mummified foetus, red diamond shaped leisons, pyrexia, lethargy, stiff gait |
Non-infectious causes of skin disease | § Flaky skin- due to parasites or deficiency in essential fatty acids § Sunburn – avoid sunlight, provide shade and water § Insect bites § Allergies § Alopecia – as get older and in summer § Skin tumours – e.g. melanomas in black bigs § Dippity pig – acute necrotising cellulitus along back – antiseptic shampoo |
Occular disease
Runny eyes | § Inflammation of snout lining § Irritation of eye due to bent/damaged eyelashes |
Fat blindness | § Excess skin obscuring eyes in overweight pigs |
