Molecular epidemiology of subgenus F adenoviruses associated with pediatric gastroenteritis during eight years in Hiroshima Prefecture as a limited area

Molecular epidemiology of subgenus F adenoviruses associated with pediatric gastroenteritis... We have studied the prevalence of the subgenus F adenoviruses and the molecular characteristics of adenovirus type 41 in Hiroshima Prefecture, Japan, as a limited area during the period of 1997–2004. Subgenus F adenoviruses were detected in 30 (3.4%) of 892 fecal specimens by enzyme immunoassay (EIA), and 80.0% (24 of 30) of positive patients were <36 months old. One (3.3%) and 29 (96.7%) of the 30 EIA-positive specimens were adenoviruses type 40 (Ad40) and 41 (Ad41), respectively. The genomes of Ad41 strains amplified by PCR were divided into two genomic type clusters (GTC1 and GTC2) based on the hexon gene as described by Li et al. (J Clin Microbiol 42: 4032–4039, 2004.). Twenty-one (95.5%) of 22 Ad41 strains detected between 2000 and 2004 belonged to GTC1, whereas all seven strains detected between 1997 and 1999 belonged to GTC2. These genomic typings were the same for the hexon and fiber genes except for one strain. This strain contained a hexon gene belonging to GTC1 and a fiber gene belonging to GTC2 and was considered to be a recombinant between adenoviruses of these types. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Archives of Virology Springer Journals

Abstract

We have studied the prevalence of the subgenus F adenoviruses and the molecular characteristics of adenovirus type 41 in Hiroshima Prefecture, Japan, as a limited area during the period of 1997–2004. Subgenus F adenoviruses were detected in 30 (3.4%) of 892 fecal specimens by enzyme immunoassay (EIA), and 80.0% (24 of 30) of positive patients were <36 months old. One (3.3%) and 29 (96.7%) of the 30 EIA-positive specimens were adenoviruses type 40 (Ad40) and 41 (Ad41), respectively. The genomes of Ad41 strains amplified by PCR were divided into two genomic type clusters (GTC1 and GTC2) based on the hexon gene as described by Li et al. (J Clin Microbiol 42: 4032–4039, 2004.). Twenty-one (95.5%) of 22 Ad41 strains detected between 2000 and 2004 belonged to GTC1, whereas all seven strains detected between 1997 and 1999 belonged to GTC2. These genomic typings were the same for the hexon and fiber genes except for one strain. This strain contained a hexon gene belonging to GTC1 and a fiber gene belonging to GTC2 and was considered to be a recombinant between adenoviruses of these types.
