BRILL ET AL.: INFECTION OF DORSAL AORTA IN YELLOWFIN TUNA 



Figure 2b. 



-The anterior dorsal aorta of a moderately infected yellowfin tuna. In the anterior end of 



the vessel (to the right) are parasites and host inflammation. 

 -The anterior dorsal aorta of a heavily infected yellowfin tuna. The vessel's lumen is all but 

 occluded by parasites and host inflammation. Ruler divisions are in mm.
