Skin flora and causes of Bacteria Viruses**
infection (abscesses etc.)
The most common causes of skin infections/abscesses in all mammalian species are members of the
Streptococci and the Staphylococci. See also, the causes of ringworm (Chapter 4) and ectoparasitic
diseases (Chapter 3). Many skin problems are secondary to nutritional deficiency (e.g. vitamin A and
vitamin B complex), endocrine disorders (e.g. thyroid) or general debilitation (e.g. old age, physiological
stress, liver damage etc.)
Cattle Trueperella (Actinomyces) All species. Warts and
pyogenes other epidermal viruses
Actinomyces bovis (lumpy jaw) (e.g. papilloma virus, pox virus)
Actinobacillus lignieresii etc.
(wooden tongue) Bovine leucosis
