This is the only faculty where veterinarians are trained in South Africa. It started in 1920 with Sir Arnold Theiler as the first dean. For the first few decades the lecturers of the Faculty were also researchers at the Onderstepoort Veterinary Institute.

Thrombosis and encephalomalacia in a case of turning sickness
(2013-05-29) koos.coetzer@up.ac.za; University of Pretoria. Faculty of Veterinary Science. Dept. of Veterinary Tropical Diseases; University of Pretoria. Faculty of Veterinary Science. Dept. of Paraclinical Sciences. Section of Pathology
Turning sickness or cerebral theileriosis is an uncommon aberrant form of infection by Theileria parva or Theileria taurotragi in which lymphoblasts parasitized by schizonts accumulate in cerebral vessels leading to thrombosis and infarction. In the more acute form areas of intense congestion and haemorrhage are present in the meninges and brain which are associated with areas of softening (Infarction) and discoloration of brain tissue. Thrombosed meningeal vessels are often very promiment. There may be severe haemorrhage into the ventricles. Histological examination shows the obstruction of arteries and arterioles by large numbers of parasitized lymphoblasts associated with haemorrhage and encephalomalacia. Similar lesions may occur in the spinal cord and infarcts may be present in the spleen.

Turning sickness or cerebral theileriosis is an uncommon aberrant form of infection by Theileria parva or Theileria taurotragi in which lymphoblasts parasitized by schizonts accumulate in cerebral vessels leading to thrombosis and infarction. Turning sickness occurs sporadically and usually in cattle younger than 3 years old. The thrombosed meningeal blood vessel is easily seen on this slides.
Small intestine of a sheep showing numerous white nodules or foci of coccidial parasites
(2009-09-30T08:50:36Z) Unknown; koos.coetzer@up.ac.za; University of Pretoria. Faculty of Veterinary Science. Dept. of Veterinary Tropical Diseases
The small intestines are unopened. The numerous white foci, 1-2 mm in diameter each comprise an area in the mucosa where there is a severe infection of epithelial cells. The reddened, hyperaemic intestinal wall indicates that an acute inflammatory process is also present.
Coccidial oocycts in sheep faeces

Microscopic appearance of coccidial oocysts in sheep faeces. Numerous round oocysts are present. The slide was prepared by the flotation technique of infected sheep faeces.
Histopathological appearance of various stages of the life cycle of an Eimeria sp. in epithelial cells of the small intestine of a sheep
(2009-09-30T08:46:35Z) Unknown; koos.coetzer@up.ac.za; University of Pretoria. Faculty of Veterinary Science. Dept. of Veterinary Tropical Diseases
Severe infection of Eimeria sp. in the epithelial cells of the mucosa. It is a histological section of one of the white nodules seen macroscopically in some cases of coccidiosis in sheep.
Eimeria stiedae in a rabbit liver

The liver is the seat of infection with the Eimeria stiedae parasite in rabbits. The photo show numerous white nodules in a rabbit liver. Each nodule comprises thousands of the various developmental stages of the organism.

The worm egg measures about 80-85 by 40-45 in size so that one can obtain an idea of the relative sizes of the two for diagnostic purposes. The preparation is made by the flotation technique of sheep faeces.

Hydrothorax in a case of heartwater
(2008-09-05T08:47:06Z) koos.coetzer@up.ac.za; University of Pretoria. Faculty of Veterinary Science. Dept. of Veterinary Tropical Diseases
After being bitten by an infected tick E. ruminantium enters the animal in the saliva of the tick. Initial multiplication of the parasiteprobably takes place in cells of the lymph node regional to the tick bite from where it enters the blood stream and invades endothelial cells in various tissues and organs. Increased vascular permeability resuylts in transudation of fluid into various body tissues (e.g. brain and lungs) and body cavities (e.g. pericardial and thoracic cavities), but the precise mechanisms responsible for the transudation are poorly understood. Pathology: the lesions in cattle, sheep and goats are similar, the most pronounced being often severe hydropericardium, hydrothorax and lung oedema with serofibrinous foam being present in the bronchi and trachea. These images illustrated a severe case.

Three stages in the life cycle of the tick Amblyomma hebraeum : male and female adults, a nymph and three larvae
(2008-05-27T06:53:53Z) University of Pretoria. Faculty of Veterinary Science
Amblyomma hebraeum is one of the tick vectors of heartwater which is an acute disease of cattle, goats, sheep and some wild ruminants caused by the rickettsia, Ehrlichia ruminantium (formely Cowdria ruminantium). Heartwater is one of the mayor diseases of livestock in sub-saharan Africa.

Trypanosomosis in a dog
(2008-03-28T09:53:23Z) Unknown; University of Pretoria. Faculty of Veterinary Science
There are no clinical signs specific for trypanosomosis. The disease may be acute, sub-acute or chronic. Acute disease may be fatal after an illness lasting 2-6 weeks, or it may developed into the chronic phrase which may last for many months. In the acute form there is fever, congested mucous membranes, anorexia, lethargy, recumbency and often death. The chronic disease (the most common form) is characterized by emaciation, weakness, lethargy, anaemia, enlarged lymph nodes and subcutaneous (dependent) oedema.
