[Genetic evolution analysis of enteric cytopathogenic human orphan virus type 30 in three cases of infants and young children in Hubei Province].
Three throat swab samples from infants and young children in Hubei Province were identified as positive for enteroviruses. All subjects were one month old, and the onset of symptoms occurred in June; these cases were sporadic and exhibited no clear epidemiological associations. The results of VP1 gene amplification analysis indicated that all three infant cases were attributed to Echovirus 30 (ECHO30). The ECHO30 strain isolated from the three samples was classified as Cluster Ⅲ within the H gene subtype. Whole genome amplification analysis revealed that the ECHO30 strain from Hubei exhibited the highest homology with ECHO30/MW586892/Ashburton/17WQ2027G/USA/2007-08-20 from GenBank, demonstrating nucleotide and amino acid homologies of 97.6% and 99.3%, respectively. Recombination analysis indicated the presence of recombination events in the non-structural protein region of the ECHO30 Hubei strain, with recombinant fragments potentially originating from ECHO30/KY888274/14-397/Germany/2013 and ECHO18 strains Echo18/MN815811/BJ2018-S6363/Beijing/2018. This study provides a comprehensive analysis of the genetic evolution of the ECHO30 strain prevalent in Hubei Province, contributing essential data for the prevention of ECHO30 infections.
期刊介绍：
Chinese Journal of Preventive Medicine (CJPM), the successor to Chinese Health Journal , was initiated on October 1, 1953. In 1960, it was amalgamated with the Chinese Medical Journal and the Journal of Medical History and Health Care , and thereafter, was renamed as People’s Care . On November 25, 1978, the publication was denominated as Chinese Journal of Preventive Medicine . The contents of CJPM deal with a wide range of disciplines and technologies including epidemiology, environmental health, nutrition and food hygiene, occupational health, hygiene for children and adolescents, radiological health, toxicology, biostatistics, social medicine, pathogenic and epidemiological research in malignant tumor, surveillance and immunization.
