Astrovirus Pathogenesis
Astroviruses are a major cause of diarrhea in the young, elderly, and the immunocompromised. Since the discovery of human astrovirus type 1 (HAstV-1) in 1975, the family Astroviridae has expanded to include two more human clades and numerous mammalian and avian-specific genotypes. Despite this, there is still little known about pathogenesis. The following review highlights the current knowledge...
متن کاملAstrovirus Diagnostics
Various methods exist to detect an astrovirus infection. Current methods include electron microscopy (EM), cell culture, immunoassays, polymerase chain reaction (PCR) and various other molecular approaches that can be applied in the context of diagnostic or in surveillance studies. With the advent of metagenomics, novel human astrovirus (HAstV) strains have been found in immunocompromised indiv...
متن کاملAstrovirus survival in drinking water.
A method based on infection of CaCo-2 cultured cell monolayers (CC) and reverse transcription-PCR (RT-PCR) was developed for the specific detection of infectious astrovirus. The procedure was validated by titrating poliovirus stocks in parallel in CaCo-2 cells by determining the most probable number of cytopathogenic units and by cell culture and subsequent RT-PCR (CC-RT-PCR). CC-RT-PCR was the...
متن کاملAstrovirus-associated gastroenteritis in children.
In a small astrovirus-associated outbreak of gastroenteritis in a ward of a local children's hospital two out of five children with symptoms excreted astrovirus particles. No astrovirus particles were found in faeces from the remaining asymptomatic child, and no other viral or bacterial pathogens were found in any of the children. Virus excretion persisted for only a few days. Rising antibody t...
متن کاملAstrovirus Replication: An Overview
Human astroviruses are important pathogens that cause gastroenteritis worldwide. Significant progress has recently been made regarding the characterization of the RNA replication process, the apoptotic response induced in virus-infected cells, and the formation of virus-like particles. First, a relationship between astrovirus RNA replication sites and the endoplasmic reticulum-derived membranes...
