Human adenovirus type 8 (HAdV-8) and 37 (HAdV-37) cause epidemic keratoconjunctivitis (EKC) associated with community-acquired and nosocomial infections. The nucleotide sequences of the entire hexon and fiber genes of eight HAdV-8 and 26 HAdV-37 strains were analysed and the transition mutations in each gene were compared among strains. Compared with prototype strains, the hexon gene of HAdV-8 and -37 strains showed between two and seven and one and twelve variations at nine and 21 different positions, respectively. All of these, except one position in HAdV-37, were located in the conserved region 4 (C4). There were only three polymorphisms in the fiber gene of both HAdV-8 and HAdV-37, fewer than those in C4. The nucleotide sequence of HAdV-8 and -37 C4 might be readily modified during EKC epidemics.
人8型腺病毒(HAdV-8)和37型腺病毒(HAdV-37)可引起与社区获得性感染和医院感染相关的流行性角结膜炎(EKC)。分析了8株HAdV-8和26株HAdV-37菌株的整个六邻体和纤维基因的核苷酸序列,并比较了各菌株每个基因中的转换突变。与原型菌株相比,HAdV-8和-37菌株的六邻体基因分别在9个和21个不同位置显示出2至7个和1至12个变异。除HAdV-37中的一个位置外,所有这些变异都位于保守区域4(C4)。HAdV-8和HAdV-37的纤维基因中只有三个多态性,比C4中的少。在EKC流行期间,HAdV-8和-37 C4的核苷酸序列可能很容易发生改变。
