On our recent trip to Phinda Private Game Reserve, some of my cousins were getting ready to be translocated to Zululand Rhino Reserve. Before they could be moved there, they had to be tested for the dreaded Bovine TB! The vets did some tests and we all waited nervously for the results! Luckily, all three of my Phinda cousins were TB free which was a big relief! Just a little bit of info about Bovine TB in lions below!
Bovine tuberculosis is a chronic bacterial disease of cattle that can sometimes affect other mammals. Cattle are the primary hosts for Mycobacterium bovis, but other wild mammals can also be infected. Warthogs, large cats (including lions, tigers, leopards, and cheetahs) and several species of rodents are commonly affected, however most mammals are susceptible to catching the disease. Lions generally contract the disease through ingesting infected prey such as buffalo or warthog.
In cats, the symptoms of Bovine TB may include weight loss, a persistent or fluctuating fever, dehydration, decreased appetite and possibly periods of vomiting or diarrhea. If the respiratory tract is affected, the cat may have coughing and difficulty breathing. Respiratory failure may occur with exercise. Skin infections are also common in cats, and may appear as a soft swelling or flat ulcer, most often on the face, neck or shoulders. In its rare form, Bovine TB may cause eye infection, detachment of the retina and eventual blindness.
In live lions, tuberculosis is usually diagnosed in the field with the tuberculin skin test. In this test, tuberculin is injected intradermally – a positive test is indicated by a delayed swelling. The test is usually carried out on the side of the neck. To obtain results that are valid, the hair is clipped around the injection site, an accurate injection of the tuberculin is given and careful pre- and post-inoculation skin thickness measurements are made. The tuberculin test can be performed using bovine tuberculin alone, or as a comparative test that distinguishes reactions to Mycobacterium bovis from reactions to environmental mycobacteria.
Bovine tuberculosis is usually controlled by test-and-euthanize. Affected prides are re-tested periodically to eliminate lions that may shed the organism; the tuberculin test is generally used. Infected prides are usually quarantined; however, test-and-euthanize techniques are guaranteed to eradicate tuberculosis from animals.
