Environmental DNA in Africa Uncovers Tuberculosis Threat Between Humans and Great Apes
Environmental DNA Analyses in Africa - Environmental DNA conducted in Africa - A recent study, using the environmental DNA (eDNA) method, has revealed the existence of tuberculosis (TB) infection risk between humans and great apes in Africa. This significant finding leads to serious consequences in the fields of wildlife conservation and public health, while once again highlighting the danger of diseases transmitting from animals to humans (zoonotic transmission).
Environmental DNA is genetic material obtained from various samples such as soil, water, or air. This innovative method allows for determining the presence, population changes, and health status of organisms without the need for direct capture or observation. This approach is of great importance for research conducted in inaccessible or sensitive ecosystems.
Through eDNA analyses, researchers have determined that Mycobacterium tuberculosis, the bacterium causing tuberculosis, is widely prevalent in both human and ape populations. This fact indicates a high probability of the disease transmitting from animals to humans and vice versa, meaning there is a significant zoonotic transmission risk. Such reciprocal infection is a major source of danger for both sides.
This research specifically focuses on the current situation on the African continent. On the continent, great apes (gorillas, chimpanzees, bonobos) live in close contact with humans, which creates fertile ground for the spread of the disease. The expansion of agricultural activities and the reduction of habitats further intensify these contacts.
This finding is of vital importance for the conservation efforts of endangered great ape species. Tuberculosis can severely reduce their populations, as diseases spread rapidly among wild animals and are difficult to treat. At the same time, this poses a significant threat to the health of local communities.
Experts specifically emphasize that the eDNA method is an effective tool for disease monitoring and early diagnosis. Based on this information, it will be possible to develop more effective intervention strategies, including preventive measures and early diagnosis programs, to protect the health of both humans and wildlife.
