Photos of Amyloodinium on barra gills

An overview of Amyloodinium can be found here

Amyloodinium can be difficult to locate on the gills when the infection is just starting. The dinospores are very small when they first attach and 100 X magnification is required. A 100 X photo of an early infection can be found here. A 400 X photo is here.

As the infection progresses, more and more dinospores are released into the water. The infection can be seen easily even at 40 X as shown here
