The microbiome refers to the collection of microorganisms, including bacteria, viruses, fungi, and other microbes, that inhabit a particular environment, such as the human body, soil, water, and plants. In the case of the human microbiome, it consists of trillions of microorganisms that reside in various parts of the body, such as the skin, mouth, respiratory tract, gastrointestinal tract, and reproductive organs. These microorganisms play a crucial role in maintaining human health and performing essential functions. The human microbiome is highly diverse, with different body sites harbouring distinct microbial communities. The composition of the microbiome can vary significantly between individuals due to various factors, including genetics, diet, lifestyle, and environmental influences. The microbiome influences numerous aspects of human health, including digestion, metabolism, immune system development and function, protection against pathogens, and even the regulation of mood and brain function. Imbalances or disruptions in the microbiome, known as dysbiosis, have been associated with various health conditions, such as gastrointestinal disorders, obesity, autoimmune diseases, allergies, and mental health disorders.
Understanding the composition and function of the microbiome is a rapidly growing field of research, and scientists are continually exploring its role in human health and potential therapeutic applications. However, microbiome datasets from African ecosystems are vastly underrepresented. There are several reasons why Africa may have limited microbiome data compared to other regions: (1) Historically, microbiome research has been concentrated in high-income countries, particularly in North America, Europe, and parts of Asia. These regions have had greater resources, infrastructure, and established research institutions to support microbiome studies. As a result, there has been less emphasis on studying microbiomes in Africa. (2) Many African countries face challenges in terms of research infrastructure, including a lack of well-equipped laboratories, advanced sequencing technologies, and funding opportunities. These limitations make it difficult to conduct comprehensive microbiome studies and generate large-scale data. (3) Collecting and analysing microbiome samples require proper protocols, sample storage facilities, and trained personnel. Access to research samples and appropriate cohorts may be limited in some regions of Africa, hindering data collection efforts. (4) Africa is known for its high genetic diversity among human populations. However, this genetic diversity also extends to the microbial communities within the continent. The unique diversity and complexity of African microbiomes present additional challenges in studying and characterizing them accurately. (5) Collaboration between African researchers and international partners can greatly enhance microbiome research. However, limited collaboration and networking opportunities between African researchers and the global scientific community have contributed to the scarcity of microbiome data from the continent.
In the Nature Reviews Microbiology Comment Article the authors discuss the bottlenecks that hinder the advancement of microbiome research and highlight key strategies for increasing microbiome research on the African continent.
