Fig. 15. Sample results obtained using the Farming Intelligene kit for
differential detection of YHV and GAV. The internal control band is
rarely seen, except with extracts from very lightly infected shrimp or
from uninfected shrimp. One Thai and Vietnamese non-virulent type
gives the same band as GAV (i.e., as shown in lanes 2, 4 and 5). A
different non-virulent type in Thailand gives only the 777 bp outer
amplicon and no nested product.
