OBJECTIVE To briefly review strategies aimed at the development of rotavirus and HPV vaccines, with emphasis on the current status of studies assessing the safety, reactogenicity, immunogenicity and efficacy of recently developed vaccines. SOURCES OF DATA This review focuses on articles published from 1996 to 2006, mainly those from the last five years, with special emphasis on data obtained ...
Human rotavirus is a major etiologic agent for infantile diarrhea worldwide. It is responsible for up to 3.3 million deaths per year in children in developing countries. Various rapid and sensitive techniques have been developed to readily diagnose rotavirus gastroenteritis. In the present study, we compared the sensitivity and specificity of immunochromatography and RNA-polyacrylamide-gel elec...
Background: Enteric viruses, particularly human rotavirus and norovirus, have been shown to replace bacteria and parasites, as the most common pathogens responsible for acute diarrhea. However, there are still few epidemiological data on the simultaneous occurrence of these viruses in Iran. In this regard, the aim of this study was to assess the useful epidemiological data on the gastroenteriti...
Rotavirus infection is the most common cause of severe gastroenteritis globally, with greater than 86% of deaths occurring in low-income and middle-income countries. There are two rotavirus vaccines currently licensed in the United States and prequalified by the World Health Organization. RV1 is a monovalent attenuated human rotavirus strain, given orally in two doses. RV5 is a pentavalent huma...
A four-layer solid phase enzyme-immunoassay (EIA) with antisera against Nebraska calf diarrhoea virus (NCDV) as immunoreagents was developed to detect human rotavirus antigens from stool specimens of patients with acute rotavirus gastroenteritis. Polystyrene beads were used as the solid phase, guinea-pig and rabbit anti-NCDV immunoglobulin as the catching and secondary antibody, and peroxidase-...
To determine whether rotavirus infections are linked to secretor status, we studied samples from children in Tunisia with gastroenteritis. We phenotyped saliva for human blood group antigens and tested feces for rotavirus. Rotavirus was detected in 32/114 patients. Secretor genotyping showed that P[8] rotavirus infected secretors and nonsecretors, and infection correlated with presence of Lewis...
patients and materials this was a across-sectional prospective study performed at the pediatric department of rasoul hospital, tehran, iran (2009-2011) on 80 hospitalized children with viral age. all stool samples were collected on viral transport media. human bocavirus (hbov) was detected using the real-time pcr taqman method. molecular detection of human parechovirus type 1 (hpev-1) rna in st...
Rotavirus vaccine development is a high priority. The association between the tetravalent rhesus-human reassortant rotavirus vaccine and intussusception has increased the need to develop new vaccines. In a small efficacy trial, the human rotavirus vaccine 89-12 recently has been shown to be safe and effective; 184 of the 215 healthy infants initially enrolled in this trial were followed for a s...
The NSP4 protein of a simian rotavirus was reported to induce diarrhea following inoculation of mice. If NSP4 is responsible for rotavirus diarrhea in humans, attenuation of a human rotavirus may be reflected in concomitant mutations in the NSP4 gene. After 33 passages in cultured monkey kidney cells, a virulent human rotavirus (strain 89-12) was found to be attenuated in adults, children, and ...
