Adenovirus isolation from spleen lymphocytes of apparently healthy pigs.
A polyethylene glycol treatment was given to fuse KSEK6 cells, an established cell line derived from porcine embryo kidney, with the lymphocytes, separated from spleens of 35 apparently healthy slaughtered pigs. Eight cytopathic virus strains were isolated from the lymphocytes of these pigs. Two virus strains were isolated by inoculating the spleen tissue homogenates to KSEK6 monolayer cultures. All of viruses were identified as porcine adenoviruses according to their physicochemical, serological and immunological properties. One of these virus strains was serologically proved to be independent from six serotypes of porcine adenoviruses ever known. The electrophoretic property of viral DNA of this strain was indicated to be different from those of other reference porcine adenoviruses. This means the presence of a 7th serotype in porcine adenoviruses.
