Kobuvirus is a newly discovered virus that belongs to the genus in Picornaviridae family, which comprised of three species including Aichivirus A , B and C . The kobuvirus isolated from human has been classified as Aichi 1 species. present study aimed assess epidemiology perform molecular characterization children admitted hospitals with acute gastroenteritis Chiang Mai, Thailand. total 923 fecal specimens collected January, 2011 December, 2013 were screened for presence by RT semi‐nested...
Human norovirus is a predominant etiological agent responsible for acute gastroenteritis across all age groups. Recently, recombinant strains have been reported as the cause of outbreaks in several settings and that mostly belong to GII. However, yet, GI never previously Thailand. The aims this study were investigate genetic recombination genotype diversity children hospitalized with Chiang Mai, Thailand during period seven years from 2015 2021. A total 2,829 stool specimens screened by...
Introduction Enteroviruses (EVs) are recognized as potential causative agents of acute gastroenteritis (AGE) in children worldwide. This study aimed to investigate the epidemiology and molecular characteristics EV infection admitted hospitals with AGE Chiang Mai, Thailand from 2019 2022. Methods A total 1,148 fecal samples collected patients were screened for presence using RT-PCR. The prevalence, co-infection common diarrheal viruses, seasonal pattern examined. genotypes identified based on...
Human norovirus is a major virus that causes acute gastroenteritis in all age groups. Recently, recombinant strains have been reported as the cause of outbreaks. This study has investigated distribution genotypes and circulating children hospitalized with diarrhea Chiang Mai, Thailand from 2017 to 2018. A total 882 stool specimens were tested for presence GI GII by reverse transcription-PCR (RT-PCR) assay. Genotypes viruses assessed partial VP1 nucleotide sequencing representative further...
Human enteric pathogens in the family Caliciviridae including norovirus (NoV) and sapovirus (SaV) are associated with acute diarrheal disease globally considered as one of viruses high genetic diversity.In order to investigate epidemiology NoV SaV pediatric patients diarrhea Chiang Mai, Thailand from January 2019 December 2020, a total 675 stool specimens were collected examined for presence by RT-multiplex PCR.126 (18.7 %) 6 (0.9 samples positive SaV, respectively. Mixed infection was...
Recombination is one of the mechanisms that plays a crucial role in genetic diversity and evolution HAstV. We wished to investigate emergence HAstV recombinant strains analyze whole-genome sequences putative detected pediatric patients with acute gastroenteritis 2011 2020.
ABSTRACT Human adenovirus (HAdV) is a common viral pathogen that causes diarrhea in children worldwide. The aim of this study was to investigate the prevalence and genotype diversity HAdV strains circulating admitted hospitals with acute gastroenteritis (AGE) Chiang Mai, Thailand, from 2018 2021. A total 1,790 stool samples were screened for by PCR method, 80 (4.5%) positive HAdV. Of these, under 5 years age accounted 90.0% HAdV-positive cases highest infection rate at group 48–60 months...
Noroviruses (NoVs) are the most significant viral pathogens associated with waterborne and foodborne outbreaks of nonbacterial acute gastroenteritis in humans worldwide. This study aimed to investigate prevalence diversity NoVs contaminated environmental water Chiang Mai, Thailand. A total 600 samples were collected from ten sampling sites Mai July 2020 December 2022. The presence NoV genogroups I (GI), GII, GIV examined using real-time RT-PCR assay. genotype virus was determined by...
Abstract Human astrovirus (HAstV) is one of the common causes acute gastroenteritis in children. The investigation molecular epidemiology HAstV essential for monitoring emergence and/or re-emergence new genotypes, as well understanding evolution circulating children suffering from gastroenteritis. present study aimed to investigate prevalence and distribution HAstVs strains hospitalized with Chiang Mai, Thailand during 2017–2020. A total 1500 fecal specimens collected were screened by RT-PCR...
Saffold virus (SAFV) is a newly discovered human which classified into the genus Cardiovirus of family Picornaviridae . A total 608 fecal specimens collected during January 2012 to December 2013 from children with diarrhea in Chiang Mai, Thailand were investigated for SAFV by RT‐nested PCR and sequence analysis. Of these, nine out (1.5%) positive SAFVs four genotypes identified, SAFV1, SAFV2, SAFV3, SAFV4. mono‐infection was found five cases (CMH‐S038–12, CMH‐S071–12, CMH‐S102–12,...
SARS-CoV-2 has been detected in feces of infected individuals and wastewater many countries, which indicates that may be used to monitor contamination the virus community. However, information about presence different types environmental water their genetic characterization are still limited. The purpose this study was investigate contaminating Thailand. We collected 600 samples from 10 sampling sites Chiang Mai city, Thailand twice a month July 2020 December 2022. RNA by real-time RT-PCR...
Recently, we reported the detection of HBoV genotypes 1, 2, and 3 in pediatric patients with acute gastroenteritis, HBoV1 2 oysters Thailand. In this study, report HBoV1, 3, 4 contamination environmental waters within same geographic area.
Objective: Human astrovirus (HAstV) is recognized as an important cause of acute gastroenteritis in children. Recombination between different genotypes HAstV can contribute to diversity and evolution the virus. This study aimed investigate emergence recombinant strains pediatric patients hospitalized with Chiang Mai, Thailand, spanning 2011–2020. Methods: A total 92 archival collected from during 2011–2020 were further characterized identify strains. The ORF1b ORF2 junction region each...
