| 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 |
| genetic diversity of norovirus, sapovirus, and astrovirus isolated from children hospitalized with acute gastroenteritis in chiang mai, thailand. | norovirus (nv), sapovirus (sv), and human astrovirus (hastv) are important causes of acute gastroenteritis in infants and young children. this study investigated the prevalence of nv, sv, and hastv infections in children hospitalized with acute gastroenteritis in chiang mai, thailand from may 2000 to march 2002. fecal specimens were tested for nv, sv, and hastv by reverse transcription polymerase chain reaction (rt-pcr) using degenerate specific primers. these viruses were characterized further ... | 2008 | 18712816 |
