No. Does your vector express any fluorescent marker (i.e. GFP, RFP) which you might be able to observe by fluorescence microscopy to determine if your transfections were successful? Based on my experience, this is not classic CPE by any means.
cells look more or less intact. With CPE cells normally clump, (swelling and clumping very typical of adenovirus), detach themselves. Try varying concentrations of adenovirus Hope this helps
