Specific properties of two enteric adenovirus 41 clones mapped within early region 1A.

ABSTRACT

Enteric adenovirus type 40 (Ad40) and Ad41 form the sixth subgenus of human adenoviruses. They are associated with infantile diarrhea but cannot be isolated in conventional cell cultures. The genome of the fastidious enteric Ad41 has been cloned, and the cleavage sites of the genome produced by restriction endonucleases BamHI, EcoRI, HpaI, NruI, PvuI, and SalI have been mapped. To develop useful hybridization methods for direct detection of adenoviruses, a restriction fragment library containing Ad41 DNA, with plasmid pBR322 as vector, has been constructed. Clones have been isolated which contain 8 of 10 possible BamHI fragments of Ad41, inserted into the BamHI cleavage site of the vector. Two of these clones are particularly useful for the detection of adenoviruses. One clone detects members of all human adenovirus subgenera, and the second clone is specific for enteric adenoviruses, in particular Ad41. A conspicuous absence of detectable homology was noted at 1.5 to 3.3 map units of the Ad41 genome in hybridizations against other serotypes of adenoviruses, including the closely related enteric Ad40. This sequence corresponds to the 5' portion of early region Ia.
