Aside from the clinical effects of bTB leading to greater mortality in affected populations the prevalence of the disease within Kruger has also been shown to drive social change with lower lion survival and breeding success with more frequent male coalition turnover and consequent higher infanticide. The digestive tract starts at the mouth and ends at the anus. These include the mouth, teeth and salivary glands in the upper portion. FIVple negative populations have been confirmed in Etosha NP although it is possible that they are infected with an as yet un-sequenced subtype.
