Of the 572 neuroscience‐related studies published in Nigerian from 1996 to 2017, <5% used state‐of‐the‐art techniques, none used transgenic models, and only one study was published in a top‐tier journal.
Simple animal model systems such as Drosophila, Zebrafish, and C. Elegans have enabled numerous breakthroughs in understanding human health and disease. Their conserved biological processes, ever-expanding established procedures for handling, and amenability for molecular and genetic manipulation, in addition to the minimal ethical concerns, have made these models preferred choices in several life science disciplines globally. Owing to their cheap maintenance cost, adopting these model systems will help bridge the research gap between Africa and the Global North and contribute to advancing scientific knowledge in African universities through practical sessions. However, the extent to which these models are used across Africa is unknown. Here, we analysed the use of Drosophila, Zebrafish, and C. elegans model systems in scientific publications from African laboratories from the year 2000 to 2021. Of 1851 PubMed-indexed publications in which at least one simple animal model was mentioned, 168 used at least one of these models for the actual investigation. With an average of 21 articles per country, South Africa, Nigeria, Kenya, Egypt, Morocco, and Tunisia contributed 75% of these studies. The remaining 25% were contributed by seven other countries at 2-7 articles per country. From here, we extracted and analysed information on funding and international collaboration. This revealed that 24.4 % of the studies were exclusively funded locally, 28.57 % exclusively funded internationally, 15.5% received both local and international funding, and the rest (31.5%) were unfunded, revealing that there is satisfactory access to funds for simple animal model studies, especially from external funders. By analysing the pattern of collaborations, we show that most of these studies had international collaborations, while very few collaborated within Africa. Our work provides data on the current state of research using simple model systems in African laboratories and argues that incorporating these models will advance biomedical science research in Africa.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
