Rotavirus A causes severe diarrhoea in infants and young children worldwide. Many unusual combinations of G and P genotypes have been observed in rotaviruses circulating in developing countries. Mixed infection of a single individual with more than one strain is a mechanism by which genetic reassortants are formed with unusual G and P combinations. However, few studies have provided direct evid...

Three sequential serum samples collected from each of 20 young children with a naturally acquired primary rotavirus infection were assayed by the radioimmunoprecipitation technique for immunoglobulin G antibodies to rotavirus structural and nonstructural proteins of the four major human rotavirus serotypes G1, P1A; G2, P1B; G3, P2; and G4, P2. Fourteen children were infected with a serotype G1 ...

objective(s) staphylococcus aureus is a foremost source of numerous nosocomial and community acquired infections. antibiotic therapy for vancomycin resistant s. aureus (vrsa) can not promise the eradication of infections. since adhesion is the major route of infections, adhesin based vaccine could suppress s. aureus infections. fibronectin binding protein a (fnbpa) and clumping factor a (clfa) ...

The three-dimensional structure of the rotavirus spike haemagglutinin viral protein 4 (VP4) has been determined to a resolution of 26 A by cryo-electron microscopy and difference analysis of intact virions and smooth (spikeless) particles. Native and spikeless virions were mixed prior to cryo-preservation so that both structures could be determined from the same micrograph, thereby minimizing s...

Rotavirus plus-strand RNAs not only direct protein synthesis but also serve as templates for the synthesis of the segmented double-stranded RNA (dsRNA) genome. In this study, we identified short-interfering RNAs (siRNAs) for viral genes 5, 8, and 9 that suppressed the expression of NSP1, a nonessential protein; NSP2, a component of viral replication factories (viroplasms); and VP7, an outer cap...

Diare menjadi penyebab kematian terbesar kedua pada balita di dunia dengan jumlah sekitar 525.000 setiap tahunnya. Salah satu utama diare adalah infeksi rotavirus. Pencegahan vaksin sudah banyak dilakukan, tetapi belum semua anak mendapatkan Tujuan literatur review ini menjelaskan potensi BACIRUS (Banana vaccine for rotavirus) yang merupakan edible berbasis protein VP4 dan VP7 tanaman transgeni...

Rotavirus infections can be diagnosed in stool samples by serological and molecular methods. We developed a novel reverse transcriptase PCR (RT-PCR) method for the amplification of rotavirus RNA and a reverse hybridization assay on a strip to detect amplimers and identify the specific G and P genotypes present in human stool specimens. An additional aim was to permit specific identification of ...

Eubenangee virus has previously been identified as the cause of Tammar sudden death syndrome (TSDS). Eubenangee virus (EUBV), Tilligery virus (TILV), Pata virus (PATAV) and Ngoupe virus (NGOV) are currently all classified within the Eubenangee virus species of the genus Orbivirus, family Reoviridae. Full genome sequencing confirmed that EUBV and TILV (both of which are from Australia) show high...

We recently described an assay that measures fusion from without induced in tissue culture cells by rotavirus, a nonenveloped, triple-protein-layered member of the Reoviridae family (M. M. Falconer, J. M. Gilbert, A. M. Roper, H. B. Greenberg, and J. S. Gavora, J. Virol. 69:5582-5591, 1995). The conditions required for syncytium formation are similar to those for viral penetration of the plasma...
