Genome stability of adenovirus types 3 and 7 during a simultaneous outbreak in Greater Manchester, UK.

A total of 96 isolates of species B adenovirus collected in Greater Manchester, UK and typed previously by serum neutralization were analyzed in five genome regions. Of these, 62 isolates were HAdV-B3 and HAdV-B7 collected during a simultaneous 15 months outbreak. The rest of the isolates were HAdV-B types 3 and 7 and other species B adenovirus types collected in different years following the outbreak.

Prevalence and quantitation of adenovirus DNA from human tonsil and adenoid tissues.

In this study, real-time PCR was used to quantify adenovirus DNA in cell suspensions prepared from 106 right and left tonsils and 10 adenoids obtained from 57 patients who underwent routine tonsillectomies and/or adenoidectomies. Eighty-four (72.4%) tonsils and adenoids samples were positive for HAdV by real-time PCR.

Sequencing and phylogenetic analysis of the hexon, fiber, and penton regions of adenoviruses isolated from AIDS patients.

Sequencing and phylogenetic analysis of the hexon, fiber, and penton regions of adenoviruses isolated between 1986 and 1997 from AIDS patients has been performed. Sequencing the L2 part of the hexon gene of 51 adenoviruses isolated between 1986 and 1997 from AIDS patients revealed only one type each from species A and C and two types from species B with all the remaining isolates from species D. Further sequencing and phylogenetic analysis of the fiber knob region of these species D adenoviruses revealed that 28/46 were intermediate strains with conflicting hexon and fiber sequences.
