| detection and characterisation of human astroviruses in children with acute gastroenteritis in blantyre, malawi. | in a 2-year hospital-based study of paediatric gastroenteritis in blantyre, malawi, astroviruses were detected by enzyme immunoassay in 15 (1.9%) of 786 inpatients and in 9 (2.3%) of 400 outpatients. greater disease severity was noted in children coinfected with human immunodeficiency virus (hiv). six human astrovirus (hastv) genotypes were identified, including hastv-1 (25%), hastv-2 (21%), hastv-3 (25%), hastv-4 (13%), hastv-5 (4%), and hastv-8 (13%). although astroviruses are not major causes ... | 2002 | 12116005 |
| first detection of a human astrovirus type 8 in a child with diarrhea in belém, brazil: comparison with other strains worldwide and identification of possible three lineages. | this study describes the genetic relationships of the first human astrovirus type-8 (hastv-8) detected in belém-brazil, during a public hospital-based study. this strain was compared with other hastv-8 strains identified elsewhere which have sequences available at genebank. the regions orf1a (primers mon348/mon340) and orf2 (primers mon269/mon270) were analyzed by nucleotide sequencing and a high similarity rate was observed among the belém strain and other hastv-8 strains. in orf1a, homology va ... | 2007 | 17612775 |
