The whole genome of a G8P[8] rotavirus from the 2006 epidemic in Croatia was sequenced and showed a Wa-like genotype constellation. Its VP7 gene clustered with DS-1-like G8 African rotaviruses and a G8P[4] German strain. Remaining genes clustered with contemporary Belgian G1P[8] rotaviruses, suggesting reassortment between human G8 and G1P[8] rotaviruses in Croatia or other European countries.

Three G3P[9] rotaviruses, detected in children hospitalized with gastroenteritis in Palermo, Italy, were found to be genetically related to strains of either human or feline origin in the VP7, VP4, and VP6 genes. In contrast, in the NSP4 gene the viruses resembled G2P[4] human strains, suggesting a reassortment between AU-1-like and Kun-like strains.

Dual typing (VP4 and VP7) of rotavirus obtained from 257 Mexican children during three epidemiological seasons was performed by reverse transcription-PCR. The P1G1 genotype was the most prevalent (40%), followed by P1G3 (19%) and P2G2 (16%). Thirty-one specimens (12%) presented mixed infections, while some genotypes were not found. This is the first dual typing of isolates from diarrhea cases i...

During a 1-year rotavirus surveillance of children hospitalized with acute gastroenteritis in Brescia Hospital, Italy, a chimerical rotavirus strain, G3P[6], was detected, displaying the VP7 and VP4 genes of porcine origin and the NSP4 and VP6 genes of human origin. The reassortant nature of the virus rules out a direct zoonotic event.

Rotavirus VP7 serotypes were identified in stools from 72.9% (1,302/1,784) of hospitalized Australian children in six cities (1989 to 1992) and comprised 1,088 (83.6%) serotype G1 isolates, 84 (6.4%) serotype G2 isolates, 64 (4.9%) serotype G3 isolates, 49 (3.8%) serotype G4 isolates, and 17 (1.3%) isolates of mixed serotypes. The most densely populated cities yielded the greatest diversity of ...

Reverse transcription-PCR analysis of drinking water in the homes of 56 children suffering from rotaviral gastroenteritis has shown the presence of the rotavirus genome in four samples. These strains were different from human rotaviruses detected in the children's feces, as determined by sequencing of the VP7-amplified fragments-three of them of animal origin (porcine or bovine) and one of huma...

Groups A, B, and C rotaviruses have been identified in cattle. Group B rotaviruses are associated with sporadic cases of diarrhea in calves and adult cows. From diagnostic submissions to our laboratory, 90 fecal samples from cases of calf diarrhea, 81 fecal samples from cases of adult cow diarrhea (winter dysentery), and 20 fecal samples from case control normal adult cows were tested for group...

Studies of rotavirus morphogenesis, transport, and release have shown that although these viruses are released from the apical surface of polarized intestinal cells before cellular lysis, they do not follow the classic exocytic pathway. Furthermore, increasing evidence suggests that lipid rafts actively participate in the exit of rotavirus from the infected cell. In this study, we silenced the ...

This investigation describes the molecular characterization of P[6]G2 rotavirus strains from hospitalized neonates with community-acquired diarrhea (CAD), nosocomial diarrhea (ND), and asymptomatic nosocomial infection (ANI) in Belém, Brazil. Twenty-six rotavirus strains with P[6]G2 genotype were sequenced to genes coding for VP4, VP7, and NSP4 proteins. Phylogenetic analysis of the VP4 gene, i...
