ABSTRACT Background. Although rotavirus and norovirus cause nearly 40% of severe endemic acute gastroenteritis (AGE) in children <5 years of age in the United States (US), there are limited data on the etiologic role of other enteric viruses in this age group.Methods. We conducted active population-based surveillance in children presenting with AGE to hospitals, emergency departments, and primary care clinics in three US counties. Stool specimens from these children and from age-matched healthy controls collected between October 2008 and September 2009 were tested for enteric adenovirus, astrovirus, sapovirus, parechovirus, bocavirus and aichivirus. Typing was carried out by sequencing and phylogenetic analysis.Results. Adenovirus, astrovirus, sapovirus, parechovirus, bocavirus and aichivirus were detected in the stool specimens of 11.8%, 4.9%, 5.4%, 4.8%, 1.4% and 0.2% of AGE patients and 1.8%, 3.0%, 4.2%, 4.4%, 2.4% and 0% of healthy controls, respectively. Adenovirus [type-41], astrovirus [types-1, 2, 3, 4, 8], sapovirus [GI and GII], parechovirus [types-1, 3, 4, 5] and bocavirus [types-1, 2, 3] were found co-circulating.Conclusions. Adenovirus, astrovirus, and sapovirus infections were detected in 22.1% of the specimens from children <5 years of age who had medical visits for AGE and tested negative for rota- and norovirus. No causal role for parechovirus and bocavirus was found.

    ABSTRACT: The aim of the study was to diagnose infections with rotavirus and other enteric pathogens in children under five years old with acute gastroenteritis and to identify the most common epidemiological and clinical characteristics of these pathogens. The study was conducted using 110 stool samples from the same number of children under five years old who were inpatients at three paediatric hospitals in Havana, Cuba, between October and December 2011. The samples were tested for rotavirus and other enteric pathogens using traditional and molecular microbiological methods. Pathogens were detected in 85 (77.3 %) of the children. Rotavirus was the most commonly found, appearing in 54.5 % of the children, followed by bacteria (29 %) and parasites (10.9 %). Other viral pathogens detected included adenovirus (6.4 %) and astrovirus (3.6 %). In rotavirus-positives cases, at least one other pathogen was detected, usually a bacterium (26.6 %). More than three episodes of watery diarrhea in 24 hours were observed in 78.3 % of the cases. Dehydration was found in 30 (50 %) rotavirus-positive children, of whom seven (11.6 %) were transferred to an intensive care unit due to complications of metabolic acidosis. Rotavirus was most commonly observed among children under 12 months old (65 %). The highest incidence of infection occurred in children who were under the care of a relative at home (78.3 %), had not been breastfed (65 %), or had been breastfed for less than six months (28.3 %). The genotype combinations most frequently found were G9P8 (28.3 %) and G1P8 (10 %). This study demonstrates the presence of rotavirus and other enteric pathogens as causes of gastroenteritis in hospitalized infants and young children in Cuba.

    ABSTRACT: Background: In the U.S., acute gastroenteritis accounts for a significant burden of medically attended illness in children under the age of five. Methods: Four multiplex RT-PCR assays were used to determine the incidence of seven viral agents (adenovirus, astrovirus, coronavirus, norovirus GI and GII, rotavirus, and sapovirus) in stool samples submitted for viral electron microscopy (EM) to the Children’s Hospital Colorado during a 34-month period (2006-2009). Results: Of 1587 stool samples submitted, 1082 (68%) were available for this study. 940 samples were from pediatric patients (median age = 2.97 years, 55% male). 132 were from adult patients submitted from an outside hospital during a 3-month period. Of pediatric samples, viral nucleic acids were detected in 245 (28%) with 28 (3.1%) samples containing more than one virus. Adenovirus was detected in 95 (10%) samples, astrovirus in 33 (4%), norovirus GI in 8 (0.9%), norovirus GII in 90 (10%), rotavirus in 49 (5.2%), and sapovirus in 2 (0.2%). No specimen was detected by the coronavirus assay. Several immunocompromised patients shed viruses for prolonged periods: norovirus for 32 weeks, astrovirus for 12 weeks, and adenovirus for 5 weeks. Of adult samples, 49 (37%) were positive for norovirus GII. PCR was more sensitive than EM, detecting 89 of 102 (87%) total adenovirus-positive samples versus 25 (25%) by EM; and 155 of 164 (95%) total astrovirus/norovirus-positive samples versus 23 (14%) by EM. EM (55 of 84, 66%) detected slightly more rotaviruses than did PCR (50, 60%). Conclusion: Noroviruses and adenoviruses are common causes of gastroenteritis in children. Immunocompromised patients can be infected with multiple viruses and shed viruses for prolonged periods. Our data support the superiority of RT-PCR compared to EM for the diagnosis of viral gastroenteritis. Continued efforts at prevention and therapeutic interventions for noroviruses are warranted.

    ABSTRACT: Sapoviruses cause acute gastroenteritis in humans and animals. They belong to the genus Sapovirus within the family Caliciviridae. They infect and cause disease in humans of all ages, in both sporadic cases and outbreaks. The clinical symptoms of sapovirus gastroenteritis are indistinguishable from those caused by noroviruses, so laboratory diagnosis is essential to identify the pathogen. Sapoviruses are highly diverse genetically and antigenically. Currently, reverse transcription-PCR (RT-PCR) assays are widely used for sapovirus detection from clinical specimens due to their high sensitivity and broad reactivity as well as the lack of sensitive assays for antigen detection or cell culture systems for the detection of infectious viruses. Sapoviruses were first discovered in 1976 by electron microscopy in diarrheic samples of humans. To date, sapoviruses have also been detected from several animals: pigs, mink, dogs, sea lions, and bats. In this review, we focus on genomic and antigenic features, molecular typing/classification, detection methods, and clinical and epidemiological profiles of human sapoviruses.
