𝐇𝐢𝐬𝐭𝐨𝐩𝐡𝐢𝐥𝐮𝐬 𝐬𝐨𝐦𝐧𝐢 is a bacterial disease of cattle that can cause a wide range of lesions throughout the body! Its primary role is as a respiratory pathogen, however.

Aortic thromboembolism is when there is a blood clot that obstructs part of the aorta. In particular, this type of thrombus tends to lodge where the aorta splits into two arteries to run down each hind leg, an area referred to as the 𝐬𝐚𝐝𝐝𝐥𝐞.

𝐏𝐞𝐫𝐢𝐭𝐨𝐧𝐞𝐨- refers to the peritoneum, which is the membrane that lines the abdomen. 𝐏𝐞𝐫𝐢𝐜𝐚𝐫𝐝𝐢𝐚𝐥 refers to the pericardium, the membrane sac that covers the heart. 𝐃𝐢𝐚𝐩𝐡𝐫𝐚𝐠𝐦𝐚𝐭𝐢𝐜 𝐡𝐞𝐫𝐧𝐢𝐚𝐬 are when some part of the intestinal tract or abdominal organs 𝐡𝐞𝐫𝐧𝐢𝐚𝐭𝐞𝐬 (protrudes) through the 𝐝𝐢𝐚𝐩𝐡𝐫𝐚𝐠𝐦, the muscular border between the abdomen and thorax that aids in breathing. So putting it all together, we have a hernia of abdominal organs through the diaphragm, due to a connection between the peritoneum and pericardium. Weird!

Swine erysipelas is a bacterial disease of pigs that is very, very common! Up to 50% of pig farms are considered to be colonized with the bacteria.

Hemangiosarcoma is a tumour of 𝐞𝐧𝐝𝐨𝐭𝐡𝐞𝐥𝐢𝐚𝐥 𝐜𝐞𝐥𝐥𝐬, which are the cells that line blood vessels.

A 𝐭𝐡𝐫𝐨𝐦𝐛𝐮𝐬 is basically a giant blood clot that completely blocks blood flow through a vessel. An 𝐞𝐦𝐛𝐨𝐥𝐮𝐬 is a more broad term, covering everything from smaller thrombi, bacteria, parasites or foreign material. Put them together, and you get 𝐭𝐡𝐫𝐨𝐦𝐛𝐨𝐞𝐦𝐛𝐨𝐥𝐢𝐬𝐦, which is a blockage of a vessel from either a thrombus or an embolus. Today, we are talking about what happens when a thrombus forms within the pulmonary veins or arteries specifically.
