The review contains some brief information on cholera epidemics in Africa. Based on the results of the whole genome sequencing of 30 clinical strains isolated in Africa in different periods of the 7th cholera pandemic (1985-2012), extensive genetic diversity has been revealed. It is demonstrated that at present cholera epidemics in Africa are caused by new variants of the agent, which emerged in South- Eastern Asia in consequence of not only new genes acquisition, but also genome alterations of pandemicity and pathogenicity islands. SNP analysis of 53 strains circulating at different times in the territory of the continent, as well as isolated in South-Eastern Asia, has been carried out. Phylogenetic relations between the majority of the African and Asian strains have been established. In addition, strains were shown to exist that are, apparently, endemic to the African region. Identified genetic diversity of the strains with varying virulence and drug resistance points out the necessity of continuous molecular monitoring of the cholera agent in Africa. |
