Group A rotavirus (RVA) represents the most important aetiological agent of diarrhoea in children worldwide. From January 2009 to December 2014, a multi-centre study realized through 11 Tunisian cities was undertaken among children aged <5 years consulting or hospitalized for acute gastroenteritis. A total of 1127 faecal samples were collected. All samples were screened by ELISA for the presence of RVA antigen. RVA-positive samples were further analyzed by PAGE and used for G/P-genotyping by semi-nested multiplex RT-PCR. Globally, 270 specimens (24 %) were RVA-positive, with peaks observed annually between November and March. Nine different electropherotypes could be visualized by PAGE, six with a long profile (173 cases) and two with a short one (seven cases). Mixed profiles were detected in two cases. Among the 267 VP7 genotyped strains, the predominant G-genotype was G1 (39.6 %) followed by G3 (22.2 %), G4 (13 %), G9 (11.5 %), G2 (5.2 %) and G12 (5.2 %). Among the 260 VP4 genotyped strains, P[8] genotype was the predominant (74. 9 %). Uncommon G/Pgenotype combinations, mixed infections and untypeable strains were also detected. This is the first report, in Tunisia, of multiple detection of an emerging human RVA strain, G12 genotype. This study highlighted the need for maintaining active surveillance of emerging strains in Northern Africa.

“…The detection of genotype G12 for the first time in Haiti further confirms the emergence of this genotype globally. 17 One important limitation of this study was that the number of samples tested and genotyped was small. Given that vaccination against RVA has begun in Haiti, it now may be difficult *Address correspondence to Michael D.

Abstract. Samples collected in 2012 through diarrheal disease surveillance in Haiti were tested for rotavirus by enzyme immunoassay and real time RT-PCR and positive samples were genotyped. The predominant genotypes were G1P[8] (29% prevalence) and G9P[8] (21%). The observed genotype prevalence was similar to that reported previously for other Caribbean countries.Group A rotavirus (RVA) is the primary cause of acute gastroenteritis in children 5 years of age worldwide. An estimated 453,000 children aged 5 years die of RVA diarrhea each year, with 85% of these deaths occurring in low-income countries.

“…To date, at least 27 G, 35 P, 16 I, 9 R, 9 C, 8 M, 16 A, 9 N, 12 T, 14 E and 11 H genotypes have been identified based on the eleven rotavirus A genes (Esona et al, 2010b;Matthijnssens et al, 2011). In humans, at least five RV-A G types (G1-G4 and G9), and two common P types (P[8] and P[4]) circulate worldwide (Banyai et al, 2012;Gentsch et al, 2005;Santos and Hoshino, 2005). G9 strains emerged in 1990s, and there has been a global description of the appearance and dominance of this genotype (Gentsch et al, 2005;Laird et al, 2003;Matthijnssens et al, 2009;Santos and Hoshino, 2005).…”

Group A rotaviruses (RV-A) are the leading cause of viral gastroenteritis in children worldwide and genotype G9P[8] is one of the five most common genotypes detected in humans. In order to gain insight into the degree of genetic variability of G9P [8] HHS Public Access BackgroundChildhood mortality has been declining worldwide as a result of socioeconomic development and implementation of prevention and survival interventions (Claeson et al., 2000). Group A rotaviruses (RV-A) are the main etiologic agent of acute gastroenteritis in infants and young children worldwide (Estes and Kapikian, 2007) and an estimated 453,000 children aged <5 years die from rotavirus diarrhea each year, with >85% of these deaths occurring in low-income countries of Africa and Asia (Parashar et al., 2009;Tate et al., 2011). Rotaviruses belong to the family Reoviridae, and the rotavirus genome consists of 11 double-stranded RNA gene segments that encode six structural (VP) and six non-structural proteins (NSP). Based on the two genes that encode the outer capsid proteins, VP4 (P-type) and VP7 (G-type), a widely used binary classification system was established for RV-A (Estes and Kapikian, 2007). This system has been recently standardized and extended to all 11 genes (Matthijnssens et al., 2008b). To date, at least 27 G, 35 P, 16 I, 9 R, 9 C, 8 M, 16 A, 9 N, 12 T, 14 E and 11 H genotypes have been identified based on the eleven rotavirus A genes (Esona et al., 2010b;Matthijnssens et al., 2011). In humans, at least five RV-A G types (G1-G4 and G9), and two common P types (P[8] and P[4]) circulate worldwide (Banyai et al., 2012;Gentsch et al., 2005;Santos and Hoshino, 2005). G9 strains emerged in 1990s, and there has been a global description of the appearance and dominance of this genotype (Gentsch et al., 2005;Laird et al., 2003;Matthijnssens et al., 2009;Santos and Hoshino, 2005). Genotype G9 strains with a Wa-like or a DS-1-like genomic configuration or a mixture thereof have been detected sporadically in localized outbreaks (Page et al., 2010). In Cameroon, the first molecular identification of genotype G9 in human samples was reported in a study conducted by colleagues in 2003 (Steele andIvanoff, 2003). At least seven major phylogenetic lineages and eleven minor lineages within G9 VP7 genes have been described (Phan et al., 2007;Wu et al., 2011). A molecular evolutionary analysis study utilizing Bayesian inference supported the idea that one single sub-lineage introduced in the 1980s was responsible for all the worldwide spread of G9 in the 1990s .In order to gain insight into the degree of genetic variability of G9P [8] Viral RNA extraction, amplification, and sequencingViral RNA from each of the 15 specimens was extracted from a 10% stool suspension made from 0.1 g or 100 μl stool in 2 ml of a 1:1 Vertrel/Water solution using either a commercial RNA extraction kit (NucliSens automated extractor, BIOMERIEUX, Durham, NC) according to the protocol specified by the manufacturer or a silica binding method described pr...
