ABSTRACT Aichi virus is a new member of the family Picornaviridae, genus Kobuvirus, and is associated with human gastroenteritis. This study detected Aichi virus in 28 of 912 fecal specimens which were negative for rotavirus, adenovirus, norovirus, sapovirus, and astrovirus and were collected in Japan, Bangladesh, Thailand, and Vietnam during 2002 to 2005. 
Detection and Genomic Characterization of Aichi Viruses in Stool Samples from Children in Monastir, Tunisia
TLDR
The high proportion of monoinfections and the high frequency of hospitalizations support the role of Aichi virus in pediatric gastroenteritis. Expand
Molecular detection of porcine kobuviruses in Italian swine.
TLDR
Based on the analysis of the partial 3D gene, the Italian sequences identified here were more closely related to PKVs previously identified in Japan, Thailand, Korea, China and Brazil than to the European PKVs recently detected in Hungary and in the Netherlands. Expand
Molecular detection of Aichi virus in raw sewage in Italy
TLDR
All of the Italian strains showed the highest nucleotide and amino acid sequence identity to genotype B AiV detected recently in Asia, especially in China. Expand
Detection of Aichi virus shedding in a child with enteric and extraintestinal symptoms in Hungary
TLDR
The genotype A virus, Kobuvirus/human/Szigetvar-HUN298/2000/Hungary (FJ225407), has 96% nucleotide identity to Aichi virus. Expand
Detection of diarrheal viruses circulating in adult patients in Thailand
A total of 332 fecal specimens collected during January-December 2008 from adult patients with diarrhea were screened for group A and C rotaviruses, noroviruses GI and GII, sapovirus, Aichi virus,Expand
Sequence analysis of the capsid gene of Aichi viruses detected from Japan, Bangladesh, Thailand, and Vietnam
TLDR
A phylogenetic tree constructed from 17 nucleotide sequences of the capsid gene of the strains studied and reference strains demonstrated that Aichi virus strains clustered into two branches. Expand
Detection of Aichi virus in South Korea
TLDR
This is the first study confirming the circulation of AiV in Korea and Genotypes A and B of Aiv were both detected in this study. Expand
Human Case of Rickettsia felis Infection, Taiwan
), we cannot exclude the possibility that the S-1-HUN–like kobuvirus can cause viremia (and generalized infection) in swine. S-1-HUN–like virus may typically cause asymptomatic infections in swine.Expand
Molecular detection of bovine kobuviruses in Italy
TLDR
Faecal samples obtained from either asymptomatic or diarrhoeic calves in Italy were screened for bovine kobuviruses using specific primers, and all of the Italian viruses formed a tight group along with BKV-like sequences previously detected in Thailand and Japan. Expand
Molecular detection and characterization of aichivirus A in adult patients with diarrhea in Thailand
TLDR
The molecular epidemiological data of Aichivirus circulating in adult patients with diarrhea at low prevalence and the viruses were genetically variable as both genotypes A and B were found in this population. Expand

Molecular characterization of the first Aichi viruses isolated in Europe and in South America
TLDR
The nucleotide sequences of both a German and a Brazilian isolate were determined, analyzed, and compared to known Aichi sequences, and the German strain turned out to be a member of genogroup A, while the Brazilian belonged to genogroups B. Expand
Isolation of Cytopathic Small Round Virus (Aichi Virus) from Pakistani Children and Japanese Travelers from Southeast Asia
TLDR
Results indicate that Aichi virus or a similar agent is endemic in Southeast Asian countries and is a cause of gastrointestinal symptoms in children in these areas or in Japanese travelers who visit there. Expand
Prevalence of newly isolated, cytopathic small round virus (Aichi strain) in Japan
TLDR
It was hypothesized that Aichi strain could be a new type of small round virus that mainly produces diarrhea in patients in the 15- to 34-year-old age group, 50 to 76% of whom possess neutralizing antibody. Expand
Application of a Reverse Transcription-PCR for Identification and Differentiation of Aichi Virus, a New Member of the Picornavirus Family Associated with Gastroenteritis in Humans
TLDR
Results indicated that RT-PCR can be a useful tool to detect Aichi virus in stool samples and that a sequence analysis of PCR products can be employed to identify the prevalent strain in each incident. Expand
Isolation of cytopathic small round viruses with BS-C-1 cells from patients with gastroenteritis.
TLDR
The results suggested that some small round viruses resembling astroviruses might show cytopathic effect in BS-C-1 cells and may be associated with an oyster-related gastroenteritis. Expand
Complete Nucleotide Sequence and Genetic Organization of Aichi Virus, a Distinct Member of the PicornaviridaeAssociated with Acute Gastroenteritis in Humans
TLDR
A dendrogram based on 3Dpol proteins indicated that Aichi virus is genetically distinct from the known six genera of picornaviruses including entero-, rhino-, cardio-, aphtho-, and hepatovirus and echovirus 22. Expand
Aichi Virus Leader Protein Is Involved in Viral RNA Replication and Encapsidation
TLDR
The data obtained in this study indicate that the Aichi virus L protein is involved in both viral RNA replication and encapsidation. Expand
Construction of an Infectious cDNA Clone of Aichi Virus (a New Member of the Family Picornaviridae) and Mutational Analysis of a Stem-Loop Structure at the 5′ End of the Genome
TLDR
Results indicate that the stem-loop at the 5′ end of the Aichi virus genome is an element involved in both viral RNA replication and production of infectious virus particles. Expand
The 5′-End Sequence of the Genome of Aichi Virus, a Picornavirus, Contains an Element Critical for Viral RNA Encapsidation
TLDR
The 5′-end sequence of the Aichi virus genome was shown to play an important role in encapsidation, and the mutation of the 7 bp of the middle part of the stem in SL-A was required for abolishing the plaque-forming ability. Expand
The 5′-Terminal Region of the Aichi Virus Genome Encodes cis-Acting Replication Elements Required for Positive- and Negative-Strand RNA Synthesis
TLDR
The results showed that the formation of three stem-loops and the pseudoknot structure at the 5′ end of the genome is required for negative-strand RNA synthesis and specific nucleotide sequences in the stem of SL-A or its complementary sequences at the 3′end of the negative- Strand were shown to be critical for the initiation of positive-strands RNA synthesis but not for that of negative-Strand synthesis.
