Adenovirus mutants carrying a defective E1A gene, such as dl312, are unable to express any of the early viral genes upon infection of HeLa cells. However, efficient expression of the other early adenovirus genes was obtained when dl312-infected HeLa cells were coinfected with pseudorabies virus, a herpesvirus. By employing a temperature-sensitive pseudorabies mutant (tsG1) it was demonstrated t...

The widely used technique of generating adenovirus vectors by homologous recombination in mammalian cells is usually not very efficient. This communication describes a simple method of generating a plasmid containing the full-length genome of an adenovirus by homologous recombination in bacteria. Following transfection of a suitable mammalian cell line with the full-length adenovirus genome, in...

Severe adenovirus pneumonia that causes acute respiratory failure can occur in infants, children, and immunocompromised patients. However, severe adenovirus pneumonia is rare in adults with a normal immune system. Adenovirus pneumonia may progress to acute respiratory failure in a few hours or a few days, and its clinical course cannot be predicted. In addition, the mortality rate is very high ...

We recently demonstrated that lactoferrin, an antimicrobial glycoprotein, can inhibit adenovirus infection by competing for common glycosaminoglycan receptors. This study further characterizes the antiadenovirus activity of the protein, thus demonstrating that lactoferrin neutralizes infection by binding to adenovirus particles and that its targets are viral III and IIIa structural polypeptides.

avian adenovirus was isolated from naturally infected birds during 1990 to 2003 in the vicinity ofkarachi, pakistan. the virus is known to cause hydro-pericardium syndrome (hps) in poultry. the mortalitywas recorded 20-50% in commercial broilers. fifty field samples were collected; however, six samples wereselected for molecular studies. these isolates were grown and characterized by cell cultu...

Butel, Janet S. (Baylor University College of Medicine, Houston, Tex.), and Fred Rapp. Replication in simian cells of defective viruses in an SV40-adenovirus "hybrid" population. J. Bacteriol. 91:278-284. 1966.-An SV40-adenovirus type 7 "hybrid" virus population, previously shown to contain two viruses capable of complementation in green monkey kidney (GMK) cells, has a growth cycle in GMK cell...

Adenovirus release is not triggered until late times after viral infection, when the adenovirus death protein (ADP) accumulates to induce viral egress. Thus, the natural rate of adenovirus release may hinder the spread of oncolytic adenoviruses. Several experimental approaches have provided evidence indicating that promoting adenovirus release can be used to enhance their therapeutic potential....

Inactivation of p53 is needed during adenovirus type 5 DNA replication. E1B55K, an adenovirus early protein, has been reported to interact with p53 and inhibit p53 transactivation. Previous studies have shown that adeno-associated virus (AAV) type 2 could reduce the transforming potential of adenovirus by rescuing p53 from adenovirus-mediated degradation, but the details are not clear yet. We d...

Adenoviral infection is a major risk factor for otitis media. We hypothesized that adenovirus promotes bacterial ascension into the middle ear through the disruption of normal function in the Eustachian tubes due to inflammation-induced changes. An intranasal infection model of the chinchilla was used to test the ability of type 5 adenovirus to promote middle ear infection by Streptococcus pneu...

Adenoviruses have been recognized as important causal pathogens of community-acquired diarrhea (CAD) among children, but their role in hospital-acquired diarrhea (HAD) is not well-understood. Hospitalized children with acute diarrhea and children who visited the outpatient department due to diarrhea were investigated from 2011 to 2012. Adenovirus was detected in stool specimens by PCR and furth...
