摘要：

An ELISA was developed using a rabbit antiserum with high levels of binding antibody against SVC virus (SVCV). Modifications were made to the standard assay which increased the sensitivity and resulted in a rapid ELISA (rELISA) which could detect SVCV antigen in cell cultures and in extracts from infected carp in approximately 1 h. When other cell-grown fish rhabdoviruses were tested, pike fry rhabdovirus (PFRV) antigen cross-reacted in the rELISA but only at a low level. Virus antigen was detected by the rELISA in clinically and sub-clinically diseased carp during an SVC epizootic but the sensitivity of detection of subclinical levels of virus was not as great as that of isolation of infectious virus in cell culture. However, antigen was detected in some fish extracts which failed to yield infectious virus. Fresh extracts of organs from healthy carp were found to give false positive reactions in the rELISA. Kidney and liver extracts from these fish were found to contain a heat labile, non-specific binding factor and further modification of the rapid assay was undertaken which successfully reduced the effect of this factor.
