Some diseases can target the lymph nodes and they become actively involved in the disease process, and these are listed below according to their causal organism and presenting symptoms. The lymph node is also a suitable place to biopsy when looking for evidence of other systemic diseases which can be diagnosed by locating evidence of them in the node using immunological laboratory techniques. These include [[Canine Distemper Virus]], [[Classical Swine Fever]], [[East Coast Fever|Bovine East Coast Fever]] and [[Leishmania|Canine Leishmaniasis]].
