Declarations
:
: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest.
: The research was conducted at the former National University of Rwanda (NUR). At the time of the study (2012–2013), NUR did not have a policy on ethical issues related to animal experiments. No permission for these experiments was or could be requested. In 2014, all public institutions of higher learning in Rwanda merged into one University of Rwanda (UoR), which established a Research Screening and Ethics Clearance Committee (RSEC-C) which can now grant permission for research involving human participants or living vertebrate animal subjects according to Ethics Operational Guidelines and Procedures.
: No human studies, and no potentially identifiable human images or data are presented in this study.
