Detection and genotyping of human adenovirus and sapovirus in children with acute gastroenteritis in Belém, Pará, between 1990 and 1992: first detection of GI.7 and GV.2 sapoviruses in Brazil

Abstract: Introduction: Acute gastroenteritis (AGE) is one of the most common causes of morbidity and mortality, especially among children from developing countries. Human adenovirus (HAdV) and sapovirus (SaV) are among the agents that cause AGE. The present study aimed to detect and genotype HAdV and SaV in 172 fecal samples from children with AGE, collected during a surveillance study carried out in a low-income community in Belém, Pará, between 1990 and 1992. Methods: HAdV was detected by nested PCR, using primers He… Show more

“…The occurrence of SV in outpatients and hospitalised settings has been reported with different rates in various developing countries [3]. In this study, the prevalence rate (14.1%) is high compared to a 7.7% SV detection rate previously reported in SA from hospitalised patients [27], 5.2% [28], and 2.5% [29] reported in Brazil. However comparable detection rate (13.9%) was observed in hospitalized patients from Pakistan [30].…”

“…The frequency of HAdV-F infections detected in this study ( n =251; 57.8%) using NGS was higher than that observed in other studies carried out in Ethiopia ( n =450; 32 %) [23], Thailand ( n =2312; 7.2 %) [54], Kenya ( n =278; 37.4 %) [55], Iraq ( n =155; 34.2 %) [56], Iran ( n =2682; 5.2 %) [57], Bangladesh ( n =871; 10.7 %) [58], Albania ( n =142; 23.2 %) [59] and PR China ( n =2233; 10.9%) [60] using conventional PCR; Tanzania ( n =1235; 3.5 %) [27] and the Republic of Congo ( n =655; 5.5 %) [61] using an enzyme-linked immunosorbent assay (ELISA); and Turkey ( n =1154; 26.2 %) [62] using an immunochromatographic test. The HAdV-F frequency obtained here was also greater than that for previous studies conducted in Brazil using distinct screening methodologies: in São Paulo ( n =193; 3.1 %) (1987–1988) [63], Goiânia ( n =557; 2.1 %) (1987–1990) [64], Porto Velho (n-591; 2.0 %) (2010–2012) [65], Campo Grande ( n =415; 3.6 %) (2000–2004) [66], Belo Horizonte ( n =392; 4.5 %) (2005–2006) [67], Juiz de Fora ( n =377; .5 %) (2007–2011) [68], Curitiba ( n =255; 16.0 %) (2010–2011) [21], Belém do Pará ( n =172; 43.0 %) (1990–1992) [69], Porto Velho ( n =877; 6.4 %) (2000–2002) [70] and the midwestern, southeastern and southern regions ( n =3003; 3.9 %) in 2012–2017 [29]. This discrepancy concerning HAdV prevalence should be considered carefully and with caution.…”

“…On the other hand, the lowest prevalence rate of HAdV infections in children (1.5%) was reported in the descriptive cross-sectional observational study conducted in Sudan by Wafa Elhag et al, 2013, which targeted children under 14 years old with acute diarrhea [ 51 ]. In comparison with other countries such as Australia, Brazil, Indonesia, Korea, Iran, the UK, Turkey, Hungary, and Sweden, the prevalence rates of HAdV infections ranged from 1% to 96.3% of patients [ 53 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 ].…”
