1. Human sapovirus GI.2 and GI.3 from children with acute gastroenteritis in northern Brazil
Human sapoviruses (HSaV) are considered important causative agents of acute gastroenteritis in humans worldwide. However, knowledge of the genetic characteristics of the whole genome of HSaV in Brazil is limited. Here we report the complete genome sequences of six HSaVs GI.2 and two GI.3 strains obtained from children with acute gastroenteritis in the Northe

2. 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, collect

3. Caliciviruses in hospitalized children, São Luís, Maranhão, 1997-1999: detection of norovirus GII.12
ABSTRACT Gastroenteritis is one of the most common diseases during childhood, with norovirus (NoV) and sapovirus (SaV) being two of its main causes. This study reports for the first time the incidence of these viruses in hospitalized children with and without gastroenteritis in São Luís, Maranhão. A total of 136 fecal samples were tested by enzyme immunoa

4. Detecção e caracterização molecular de sapovírus em suínos assintomáticos
Porcine sapovirus (PoSaVs) infections are frequent in pig herds in America, Europe and Asia. The infection can be symptomatic, in which the typical clinical signs is diarrhea. However, asymptomatic infections are described with relative frequency. The genetic diversity of the PoSaV is high. Five genogroups and 16 genotypes are well established and five genog

5. Detection of caliciviruses associated with acute infantile gastroenteritis in Salvador, an urban center in Northeast Brazil
Acute gastroenteritis caused by viruses is one of the leading causes of infantile morbidity. The aim of the present study was to investigate the presence of human caliciviruses of the genera norovirus and sapovirus in children up to 3 years of age with acute gastroenteritis from low-income communities in the city of Salvador, Brazil. This study is an extensi

6. Detection and molecular characterization of enteric caliciviruses in swine herds in the State of Rio de Janeiro / Detecção e caracterização molecular de calicivírus entéricos em suínos de rebanhos do Estado do Rio de Janeiro
O presente estudo teve como objetivo identificar circulação de calicivírus entéricos porcinos (PEC) em fezes/conteúdo intestinal de suínos (Sus scrofa) de propriedades (suinoculturas e abatedouro) localizadas no Estado do Rio de Janeiro. Os PEC pertencem a dois gêneros da família Caliciviridae: Norovirus e Sapovirus. São capazes de causar gastroente

7. Detecção e análise filogenética do calicivírus entérico suíno, geneticamente relacionado com a estirpe Cowden do genogrupo III do sapovírus, em rebanhos brasileiros
O sapovírus classificado na família Caliciviridae é um importante causador de gastroenterite aguda em crianças e leitões. O gênero Sapovirus é dividido em sete genogrupos (G), sendo que as estirpes dos GIII, GVI e GVII estão associadas com infecção em suínos. Apesar da alta prevalência da infecção em alguns países, ainda não existem estudos r

8. Freqüência de diagnóstico e caracterização molecular do calicivírus entérico suíno em rebanhos brasileiros
Os membros do gênero Sapovirus (SaV) são divididos em cinco genogrupos com base na similaridade do gene da proteína principal do capsídeo. Estirpes de quatro desses genogrupos podem ocasionar diarréia em seres humanos e apenas o genogrupo III (GIII) é relacionado à infecções entéricas em suínos. O protótipo do GIII é a estirpe Cowden, que é a �

9. Detection of calicivirus from fecal samples from children with acute gastroenteritis in the West Central region of Brazil
The objective of this study was to describe the circulation of caliciviruses in the West Central region of Brazil and its correlation with children's gender and age, as well as with the year and months of the sample collection. Reverse transcriptase-polymerase chain reaction was performed to detect the human calicivirus genome in 1006 fecal samples that were

10. Genetic Diversity of Norovirus and Sapovirus in Hospitalized Infants with Sporadic Cases of Acute Gastroenteritis in Chiang Mai, Thailand
Stool specimens from hospitalized infants with sporadic gastroenteritis in Chiang Mai, Thailand, between July 2000 and July 2001 were examined for norovirus and sapovirus by reverse transcription-PCR and sequence analysis. These viruses were identified in 13 of 105 (12%) specimens. One strain was found to be a recombinant norovirus.

11. Mutational study of sapovirus expression in insect cells
Human sapovirus (SaV), an agent of human gastroenteritis, cannot be grown in cell culture, but expression of the recombinant capsid protein (rVP1) in a baculovirus expression system results in the formation of virus-like particles (VLPs). In this study we compared the time-course expression of two different SaV rVP1 constructs. One construct had the native s

12. Bile acids are essential for porcine enteric calicivirus replication in association with down-regulation of signal transducer and activator of transcription 1
A porcine enteric calicivirus (PEC), strain Cowden in the family Caliciviridae (genus Sapovirus), can be propagated in a continuous cell line, LLC-PK cells, but only in the presence of an intestinal content fluid filtrate from gnotobiotic pigs. This cell culture system is presently the only in vitro model among caliciviruses that cause gastrointestinal disea
