“…In the past several years, the G9 serotype has emerged as the fifth common type worldwide, including in Europe (4,6,31,33,35,(42)(43)(44)48). In our study, G9 rotavirus strains were generally identified at relatively low rates (Table 2), ranging from the 1.5% to 10.2%.…”

“…The only exception was Bulgaria, where the prevalence of G9 strains was overall 34.3% and was as high as almost 60% of all cases detected during the epidemic peak of 2006. Analysis of nucleotide sequences of representative G9 strains found in this study revealed in all cases a close relationship to most G9 strains recently identified in European, American, African, and Asian countries (4,6,33,44,49), which are more closely related to each other than to earlier G9 strains isolated in the 1980s (31). The surveillance of G9 strains is particularly important, because the degree of protection of current vaccines against this serotype is yet to be confirmed.…”

Based on nucleotide sequence and phylogenetic analysis of the partial VP6 genes, group A rotaviruses can be mainly differentiated into two genogroups. In this study, a method employing reverse transcription-PCR (RT-PCR) and degenerate primers was established to assign the VP6 genogroup. VP6 genogroup I and genogroup II could be determined according to the sizes of the amplicons: 380 and 780 bp, respectively. The VP6 genogroup of human reference strains of G1 to G4 and G9 types and RotaTeq vaccine strains could be properly assigned by RT-PCR. Eighty rotavirus-positive fecal samples were subjected to enzyme-linked immunosorbent assay (ELISA), RT-PCR, and sequencing of the partial VP6 gene for subgroup and genogroup determination. The results correlated well among these three methods, except for seven samples whose subgroups could not be determined by ELISA. VP6 genogroups of another 150 rotavirus strains recovered between 1981 and 2005 were determined by RT-PCR and sequencing, and the same results were obtained by these two methods. Furthermore, an additional 524 rotavirus-positive fecal samples were tested by RT-PCR, and the VP6 genogroups could be easily determined. The RT-PCR assay developed here provided a reliable and convenient method for assigning the VP6 genogroups of human rotaviruses with a wide range of genetic variation.

“…Moreover, Lin et al [36] and Chen et al [19] also found that G9 rotaviruses emerged between 2000 and 2002 in northern Taiwan, as well as between 2001 and 2003 all over Taiwan. In their studies, most of the G9 strains belonged to G9 P [8] [19,36], subgroup II, and long electrophorotype, and only one strain belonged to G9 P [4], subgroup II, and short electrophorotype [36]. Nevertheless, it has been reported that G2 strains were detected from 1981 to 1987, and then became undetected for several years until 1992.…”

Acute infectious gastroenteritis causes high morbidity and mortality in children worldwide. The most important cause of gastroenteritis is virus infection. Diarrhea is the dominant symptom of viral gastroenteritis. It subsequently induces dehydration and malnutrition, which contribute to high morbidity and mortality in children. In Taiwan, rotavirus is the major cause (30.4-48%) of infectious gastroenteritis, followed by adenovirus (9.1-19.8%), norovirus (8.2-25%), enterovirus (< 5.2 %), astrovirus (2.7-2.9%) and other viruses (including sapovirus)(< 1 %). Untreated gastroenteritis is the major cause of infantile mortality, which leads to human tragedy and economic burden. In Taiwan, the cost of admission or hospitalization associated with gastroenterovirus infection is about more than 40% of the monthly salary of an unskilled or service worker. Understanding the epidemiology of gastroenterovirus and its induced host immune response could benefit the development for prevention and therapeutic management of gastroenterovirus. This review summarizes the epidemiological information and current knowledge of gastroenteroviruses that cause gastroenteritis in Taiwan.
