One of the earliest and most striking observations made about HIV is the extensive genetic variation that the virus has within individual hosts, particularly in the hypervariable regions of the env gene which is divided into 5 variable regions (V1-V5) and 5 more constant (C1-C5) regions. HIV evolves at any time over the course of an individual's infection and infected individuals harbours a population of genetically related but non-identical viruses that are under constant change and ready to adapt to changes in their environment. These genetically heterogeneous populations of closely related genomes are called quasispecies. Tuberculosis or tubercle forming disease is an acute and/or chronic bacterial infection that primarily attacks the lungs, but which may also affect the kidneys, bones, lymph nodes, and brain. The disease is caused by Mycobacterium tuberculosis (MTB), a slow growing rod-shaped, acid fast bacterium. It is transmitted from person to person through inhalation of bacteria-carrying air droplets. Worldwide, one person out of three is infected with Mycobacterium tuberculosis, two billion people in total. TB currently holds the seventh place in the global ranking of causes of death. In 2008, there were an estimated 9.4 (range, 8.9-9.9 million) million incident cases (equivalent to 139 cases per 100 000 population) of TB globally. ...
