Figure 1From: Clinicopathological features and immunohistochemical detection of antigens in acute experimental Streptococcus agalactiae infection in red tilapia (Oreochromis spp.) A and B: Ethidium bromide-stained 1.5% agarose gel of multiplex PCR products. All the samples S. agalactiae substrains yielded a single 1457-bp product, indicating the presence of the 16s ribosomal ARN gene sequence. Molecular size markers are shown on the left.
