| Summary: | Three virus particles were isolated in vitro and
tentatively classified into three groupings , namely
Herpesviridae, Birnaviridae and Iridoviridae . Virus
groupings were based on the ultrastructural morphology and
cytopathology observed . Distinct virus-like cytopathic
effects were noted on four established fish cell lines
viz . CHSE-214 , GCK-84 , EPC and TmB , utilized in the
study . The virus - like particles , from pelleted infected
cell cultures and clarified cell culture supernatant, were
visualized under transmission electron microscopy .Virus titration utilizing BB cells for the
Birnavirus - like isolate achieved a mean titre of 7.40 X 105
TC ID50/ml. Relatively high virus titres were also recorded from the other two isolants , with a mean virus titres of
7.16 X 105 TC ID50/ml for Herpesvirus - like and 6.4 6 'x 105
TCID50/ml for Iridovirus-like . |
