As for physical causes they, except for hypothermia, rarely contribute to the death of an animal but can be aggravated through situations in which chemical or biological problems are involved because they cause an animal stress and weaken its immune system. Stress is brought about by environmental conditions such as a drafty barn, improper diet, poor sanitation, handling etc.
Biological organisms:
A biological organism that causes disease is called "pathogen". Most diseases such as pneumonia, and scours are caused by bacteria or viruses. Not all bacteria are harmful, some are important to good health, but this is not the case with most. Bacteria is usually treated with antibiotics, however, some bacteria are resistant to certain antibiotics and won't work against a particular illness. Scientific study has revealed that in the case of humans, a lot of the antibiotic resistance we come across today stems directly from the improper use of antibiotics in animal agriculture when animals are fed antibiotics indiscriminately and farmers do not follow the withdrawal times
Viruses do not respond to antibiotics at all. The good news is that sheep are more resistant than other livestock to bacterial and virus diseases.
Yeasts and fungi do not very often cause a shepherd problems, however, they can cause some skin problems, respiratory infections, and the infection in a ewe's udder called mastitis. Both yeast and fungi infections are often brought about by the extensive use of antibiotics.
IDENTIFICATION OF PARASITES
The most common problem a shepherd encounters is that of internal and external parasites.
Whereas sheep are more resistant to bacterial and virus diseases they are more prone to parasites. Parasites affect all ages of sheep but are most active in lambs and young ewes and can cause death.
A parasite is an organism that gets its food and/or shelter from another organism. Most are relatively benign, and are just a nuisance, whereas others such as intestinal worms may cause serious illness and death. When sheep are affected by parasites they become weak and run-down, and very often sick and prone to a secondary bacterial or viral disease.
Parasites can attack most parts of a sheep's body, so remember to keep your pastures clean to avoid severe parasitic infections. The breed "Gulf Coast Natives" is known for its high tolerance to parasites.
