BACKGROUND Recently, epidemiological and clinical data have revealed important changes with regard to clinical adenovirus infection, including alterations in antigenic presentation, geographical distribution, and virulence of the virus. METHODS In an effort to better understand the epidemiology of clinical adenovirus infection in the United States, we adopted a new molecular adenovirus typing...
Application of the polymerase chain reaction (PCR) method for detection of subgenus B adenoviruses (types 3, 7 and 11) was investigated. It is based on a simple (nonnested) PCR using primer pairs specific for the hexon-coding region. The PCR allowed amplification of DNA from subgenus B adenovirus prototype strains (types 3, 7 and 11) and adenovirus isolates (types 3 and 7), whereas it did not a...
Monoclonal antibodies (MoAbs) were generated following immunization of Balb/C mice with adenovirus type 5 grown in Hep2 cell line. Six clones reactive to hexon antigen of the virus were stabilized, of which 4 had mu-heavy chain specificity and 2 were of gamma-heavy chain type. Three of the clones (ADV-1, ADV-3 and ADV-5) had a high ELISA reactivity to the hexon antigen but exhibited differentia...
Antibodies against hexon, the major coat protein of adenovirus (Ad), are an important component of the neutralizing activity in serum from naturally infected humans and experimentally infected animals. The mechanisms by which antihexon antibodies neutralize the virus have not been defined. As a model system, murine monoclonal antibodies raised against Ad type 5 (Ad5) were screened for antihexon...
Previous observations that the adenovirus type 5 (Ad5) E4orf6 and E4orf3 gene products have redundant effects in viral lytic infection together with the recent findings that E4orf6 possesses transforming potential prompted us to investigate the effect of E4orf3 expression on the transformation of primary rat cells in combination with adenovirus E1 oncogene products. Our results demonstrate for ...
Adenoviruses infect a wide range of vertebrates including humans. Their icosahedral capsids are composed of three major proteins: the trimeric hexon forms the facets and the penton, a noncovalent complex of the pentameric penton base and trimeric fibre proteins, is located at the 12 capsid vertices. Several proteins (IIIa, VI, VIII and IX) stabilise the capsid. We have obtained a 10 A resolutio...
Since the first observation with the electron microscope of intranuclear virus-like particles in sections of tissue culture cells infected with adeno-virus (1), numerous later studies of similar material have established certain morphological features of this agent (2-5). The particles have been reported to be round or ellipsoid and an inner body and outer limiting membrane have been described ...
Analytical ultracentrifugation, thermal denaturation, and electron microscopy have been used to study nucleoprotein core particles, obtained from disrupted type 5 adenovirus and partially purified on glycerol density gradients. Electron microscopy at low salt concentrations has shown that the cores are homogeneous particles with characteristic structures, which vary with conditions of observati...
Adenovirus type 12 (Huie) inoculated into cultures of primary whole rat embryo produced foci of morphologically altered cells. The number and identification of these transformed areas was dependent upon the calcium concentration of the medium; more foci appeared in 0.1 mm than in 1.8 mm calcium. Cell lines derived from these inoculated cultures did not yield infectious virus, and also were simi...
