Full genome characterization of human Rotavirus A strains isolated in Cameroon, 2010-2011: diverse combinations of the G and P genes and lack of reassortment of the backbone genes.

Over the past few years whole genome sequencing of rotaviruses has become a routine laboratory method in many strain surveillance studies. To study the molecular evolutionary pattern of representative Cameroonian Rotavirus A (RVA) strains, the semiconductor sequencing approach was used following random amplification of genomic RNA. In total, 31 RVA strains collected during 2010-2011 in three Cameroonian study sites located 120 to 1240 km from each other were sequenced and analyzed.

Group A rotaviruses (RVA) are an important enteric pathogen in humans and livestock animals. Transmission of animal RVA strains to humans has been documented on several occasions. A reverse route of transmission of RVA under natural circumstances is anticipated, although evidence is scarce.
