Adeno Virus

 Non-enveloped, DNA (ds DNA) Virus
 Has characteristic morphology consisting of an icosahedral shell composed of 20 equilateral triangular faces and 12 vertices → space vehicle appearance.
 Human adenovirus grows only in tissue culture of human origins, such as human embryonic kidney, HeLa or HEP-2.
The cytopathic effect in tissue culture → cell rounding and aggregation into grape-like clusters.
 Adenovirus has been used as a vector for gene therapy.
