Marine Mammal Parasite of the Month- October 2021 Reply – Nationwide Marine Life Heart


This parasite is Braunina cordiformis! Bear in mind final time how we mentioned it was coronary heart formed? Nicely, cordiform means coronary heart formed, so its scientific identify is definitely based mostly on its form! This parasite is the one species within the household Brauninidae and is discovered within the fundic (important) and pyloric stomachs and duodenal ampullae. It’s thought that the membrane like construction surrounding the physique of the parasite protects the parasite from the acidic nature of the abdomen. These flukes connect to the mucous membrane within the abdomen in bottlenose dolphins. They trigger injury by pulling on the gastric wall and inflicting the connective tissue beneath to stay out, damaging the the wall’s tissue and the cells within the mucous layer and inflicting persistent gastritis. Nonetheless, the extent of harm is unknown and there seems to be little or no different unfavourable results.
