Astrovirus Diagnostics

Astrovirus 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...

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...

Astrovirus 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...

Rotavirus and Astrovirus

Seroepidemiology of astrovirus MLB1.

To determine the seroprevalence of astrovirus MLB1 (MLB1), an indirect enzyme-linked immunosorbent assay (ELISA) was established. MLB1 seropositivity was high in children <6 months old, decreased to a nadir at 12 to 23 months old, and increased to 100% by adulthood. MLB1 infection is common, and primary exposure occurs in childhood.
