Detection of an unusual G8P[8] rotavirus in a Rotarix-vaccinated child with acute gastroenteritis using Nanopore MinION sequencing A case report

초록

Rationale: Rotavirus is routinely diagnosed by the detection of antigens or the viral genome. However, these tests have limitations, in that they do not detect all rotavirus strains. Patient concerns: We present a case of a 27-month-old girl who was hospitalized for 4 days with severe gastroenteritis, including high fever, vomiting, diarrhea, mild dehydration, and periumbilical pain. Notably, the patient previously received the Rotarix vaccine. Diagnoses: The laboratory tests were negative for rotavirus, astrovirus, adenovirus, and norovirus as well as common diarrhea-causing bacteria. Human-bovine recombinant rotavirus was detected by MinION sequencing. Interventions: To investigate the cause agents from the unexplained severe gastroenteritis infant, the stool sample was prepared by random amplification for Nanopore MinION sequencing. Outcomes: Treatment through the administration of ORS solution and galtase powder with probiotics was successful after the diagnosis of unusual rotavirus infection. Lessons: This case report is the first detection of an unusual human-bovine recombinant rotavirus in an idiopathic gastroenteritis using Nanopore MinION sequencing.
