Antibody found in the skin of rainbow trout

The antibody found in the gut of rainbow trout, known as IgT

Fish, like humans, can be attacked by microbes. Many of these microbes use the skin of fish to grow, which produces damage and even death to the animal. However, fish have developed weapons to fight back these microbes. In the image, we can see a microbe with a ghost-like shape that is attacked by a fish molecule called IgT. To visualize IgT attacking the microbe, the researchers have stained IgT with a green color. The image shows how this microbe is completely surrounded by IgT.

The research was supported by grants from the National Institute of General Medical Sciences and the National Science Foundation.
