“…Human GARVs showed a striking seasonal pattern of infection in developed countries, with epidemic peaks occurring in the cooler months of each year (Estes and Kapikian, 2007). This may be related to the influence of low relative humidity as a factor facilitating the survival of GARVs on surfaces (Brandt et al, 1982). Studies describing the seasonal pattern of porcine GARVs in diarrheic piglets have rarely been published, and those published data varied widely Svensmark et al, 1989).…”

Porcine group A rotavirus (GARV) is considered to be an important animal pathogen due to their economic impact in the swine industry and its potential to cause heterologous infections in humans. This study examined 475 fecal samples from 143 farms located in 6 provinces across South Korea. RT-PCR and nested PCR utilizing primer pairs specific for the GARV VP6 gene detected GARV-positive reactions in 182 (38.3%) diarrheic fecal samples. A total of 98 porcine GARV strains isolated from the GARV-positive feces were analyzed for G and P genotyping. Based on the sequence and phylogenetic analyses, the most predominant combination of G and P genotypes was G5P[7], found in 63 GARV strains (64.3%). The other combinations of G and P genotypes were G8P[7] (16 strains [16.3%]), G9P[7] (7 strains [7.1%]), G9P[23] (2 strains [2.0%]), and G8P[1] (1 strain [1.0%]). The counterparts of G or P genotypes were not determined in three G5, five P[7], and one P[1] strains. Interestingly, phylogenetic analysis indicated that all Korean G9 strains were more closely related to lineage VI porcine and human viruses than to other lineages (I-V) of GARVs and to Korean human G9 strains (lineage III). These results show that porcine GARV infections are common in diarrheic piglets in South Korea. The infecting strains are genetically diverse, and include homologous (G5P[7]), heterologous (G8P[1]), and reassortant (G8P[7]), as well as emerging G9 GARV strains.

samples from 1,537 pediatric inpatients with gastroenteritis were tested for enteric viruses by electron microscopic and rotavirus enzyme-linked immunosorbent assay techniques. Rotaviruses were detected in 34.5% of these patients, enteric adenoviruses were detected in 4.7%,-27-nm viruses were detected in 1.6%, and at least one of these agents was found in 40.1% of the study subjects. Three infections were by an apparently new agent which morphologically is a rotavirus, but which failed to react in the rotavirus enzyme-linked immunosorbent assay. During the first 8 calendar years of study, rotaviruses were detected in 39.0% of 577 patients in the even-numbered years and 30.3% of 702 patients in the odd-numbered years. Adenoviruses were found in all calendar months. Rotaviruses were found in inpatients in November through July, whereas-27-nm viruses were found in October through June. The percentage of patients who had a demonstrated viral infection rose steadily from 7.4% in September to 72.0% in January and then steadily declined to 2.9% in August. Viral infection was especially common in study subjects who were 7 through 24 months of age; 61% of such children had one or more enteric viruses. Rotavirus-infected patients tended to be younger during the months of greatest rotavirus activity than at the beginning and end of the rotavirus season, presumably because of a greater exposure to virus at the height of the rotavirus outbreak. In recent years, previously unrecognized rotaviruses, adenoviruses, and miscellaneous, mostly small (-27-nm) viruses have been detected and associated with gastroenteritis (

“…In countries located in the temperate zone, including Japan, it is well known that sporadic acute gastroenteritis due to human rotavirus (HRV) infections recurs every winter, and that the wax and wane of rotavirus epidemic is closely related to a change in outdoor temperature by season (3,11). Similar mode of rotavirus prevalence was also seen in Gifu city (9).…”

A total of 348 fecal specimens collected from children with acute gastroenteritis in Gifu city over three consecutive winter seasons (from November 1986 to March 1989) were examined for group A human rotavirus (HRV) by either a commercial test kit or a sandwich enzyme-linked immunosorbent assay (sandwich ELISA).One hundred twelve of the 173 group A HRV-positive specimens were further subjected to serotype determination by ELISA with four serotype-specific monoclonal antibodies to VP7 (ELISA-serotyping).Ninety-one specimens ( 81.3% ) were successfully serotyped: 41 (36.6%) were serotype 1, 13 (11.6%) serotype 2, 27 (24.1%) serotype 3, and 10 (8.9% ) serotype 4. The serotypes of the remaining 21 (18.8%) could not be determined.The predominant serotype of HRV that prevailed in Gifu city changed every winter: serotype 3 (63.4%) was most prevalent in the 1st winter, serotype 4 (42.9%) in the 2nd winter, and serotype 1 (64%) in the 3rd winter.
