- Abstract
- Aichivirus-A (AiV-A), a member of the Kobuvirus genus of the family Picornaviridae, was first reported in stool samples of patients with non-bacterial gastroenteritis in Aichi Prefecture, Japan, in 1989. AiV has been reported from in various aquatic environments, such as surface water and sewage, can be transmitted via the fecal-oral route through contaminated water. As AiV is known to acute gastroenteritis worldwide, developing methods for AiV detection from contaminated environments and food is required. In the present study, we established an effective polymerase chain reaction (PCR) method to detect AiV. Various real-time reverse transcription (RT)-PCR and conventional PCR methods for AiV detection were compared, and the limit of detection was confirmed by comparing the sensitivity at varied primer concentrations and PCR conditions. The final detection limits were 102 copy/mu L in conventional PCR, and 101 copy/mu L in the real-time RT-PCR. The optimized method used in this study might aid in detecting AiV contamination.
