Astrovirus in faeces of children with acute gastroenteritis in Rio de Janeiro, Brazil

An outbreak of gastroenteritis associated with astrovirus serotype 1 in a day care center, in Rio de Janeiro, Brazil

“…Our data corroborate the findings reported by Mendes (1997) during a serosurvey study conducted in Belém, Brazil, when it was demonstrated that HAstrV seropositivity rates increased from 13.9%, at 6 months of age to 64.9% in children up to 2 years old, suggesting that HAstrV infection is more frequent than the previously reported (Nozawa et al 1985, Leite et al 1991, Stewien et al 1991, Timenetsky et al 1993, Tanaka et al 1994.…”

“…The symptoms associated with diarrhea persisted for three to six days. detection could explain the low rate of detection and the lack of information about the circulating HAstrV types (Nozawa et al 1985, Leite et al 1991, Stewien et al 1991, Timenetsky et al 1993, Tanaka et al 1994. However, in a study carried out among inpatient children, we detected different serotypes of HAstrV circulating at higher rate (15%) (Silva et al unpublished observations).…”

“…In Brazil, there are few reports describing HAstrV infections (Nozawa et al 1985, Leite et al 1991, Stewien et al 1991, Timenetsky et al 1993, Tanaka et al 1994) and all of them have used EM only for virus detection.…”

Identification of turkey astrovirus and turkey coronavirus in an outbreak of Poult Enteritis and Mortality Syndrome

“…Astroviruses are known as the causative agents of acute gastroenteritis in mammals and turkeys (Kurtz et al, 1977;Bridger, 1980;McNulty et al, 1980;Reynolds et al, 1987a;Leite et al, 1991;Tanaka et al, 1994), as well as acute nephritis in chickens (Imada et al, 2000). In turkeys, infections usually occur during the first four weeks of age (Reynolds et al, 1987b) and are more prevalent than infections by any other enteritis-causing agent in poultry (Reynolds & Saif, 1986;Reynolds et al, 1987a;Saif et al, 1985), leading to a moderate increase in mortality .…”

Prevalence and genetic diversity of astroviruses in children with and without diarrhea in São Luís, Maranhão, Brazil

“…These studies focused on surveillance for gastroenteritis in hospitals and day-care centers, as well as on self-limited outbreaks (Leite et al 1991, Timenetsky et al 1993, Tanaka et al 1994, Silva et al 2001, Cardoso et al 2002.…”
