HAdVD23 and two novel adenoviruses, HAdVD60a and HAdVD62, isolated from feces of AIDS patients in Manchester, United Kingdom, have been sequenced. The HAdVD60a genome lacks the penton arginine-glycine-aspartic acid (RGD) motif and differs from HAdVD60 by a recombinant E3 region. HAdVD62 has penton, hexon, and fiber regions not previously found in other adenoviruses.

avian influenza is an important disease of poultry with the potential to cause major epidemics resulting in significant economic losses. the presence of avian influenza viruses (aiv) in chickens in iran has not been previously reported. an avian influenza outbreak in broiler, layer and breeder farms occurred during a very hot summer in july 1998. three aiv isolates designated as 101, 102 and 10...

Many immuno-therapeutic strategies are currently being developed to fight cancer. In this scenario, oncolytic adenoviruses (Onc.Ads) have an interesting role for their peculiar tumor selectivity, safety, and transgene-delivery capability. The major strength of the Onc.Ads is extraordinary immunogenicity that leads a strong T-cell response, which, together with possibility delivery therapeutic t...

The strains of types 1 to 4 adenoviruses studied attained maximum combination with host cells, strain HeLa, in 5 to 6 hours. During this adsorption period approximately 75 per cent of the total virus became associated with the host cells. Following adsorption of virus to HeLa cells, these agents underwent cyclic multiplication periods similar to bacterial and other animal viruses. The latent or...
