In most cases, however, we have found it impossible to procure an adequate sample for bacteriology. Rose and Hodgson didn't offer sure-fire diagnostic techniques for lymphangitis in their reports, and their protocol for treatment and the potential for success also emphasized the confusing nature of the affliction. Rose and Hodgson found that cold hosing and pressure bandaging sometimes were helpful in the early stages of the condition. Some cases, they noted, will improve temporarily following exercise, and some will resolve spontaneously with rest. It also can be frustrating to the horse owner.
Afflicted horses are unable to work or perform, and sometimes the recuperative period is long.
What Rose and Hodgson have described is basic lymphangitis. However, the disease can take another turn, especially when harmful bacteria invade. This condition is known as ulcerative lymphangitis and is characterized by nodules of swelling that often break and drain. This condition is believed to be caused by bacteria that gain access to the lymphatic system through cuts or abrasions on the legs. It can be spread by spores on contaminated bedding and might even survive in the soil.
