Predominance of rotavirus G9 genotype in children hospitalized for rotavirus gastroenteritis in Belgium during 1999–2003

Molecular epidemiology of rotaviruses in Bulgaria: annual shift of the predominant genotype

“…Although a reduction in the episodes of gastroenteritis attributable to rotaviruses was seen between 2005 and 2008, it is not clear whether the recent introduction of rotavirus testing and sampling for the current study may be a confounding factor, and only continued surveillance will allow the monitoring of this trend in the long term. [17,18,23,[37][38][39][40][41]. These fluctuations may be driven by herd immunity and the emergence of a particular genotype may reflect the buildup of a sufficiently large population of susceptible children.…”

G8Rotavirus Strains Isolated in the Democratic Republic of Congo Belong to the DS-1-Like Genogroup

“…The replacement of the P [6] specificity in DRC86 (G8P [6]), which is believed to be of animal origin, with the P [8] specificity, very well adapted to infect humans, might make this G8P [8] RV strain a successful human pathogen in a way similar to that described for the G9P [8] HRV strains all over the world (29,55). This G8P [8] combination should be taken into account by vaccine companies, although the P [8] moiety included in several vaccines currently under development might convey some level of protection against severe gastroenteritis due to G8P [8] RV infection.…”

“…At least 11 G types have been isolated from humans, but only G1, G2, G3, G4, and G9 are currently of epidemiological importance (16,55). G8 RVs are common in cattle, but they also constitute a significant proportion of human RV (HRV) strains in African countries (11,62).…”

Prevalence and Molecular Genotyping of Group A Rotaviruses in Iranian Children

“…The capacity of the first-generation of rotavirus vaccines to provide heterotypic protection against other G-types is unclear [8].…”
