Lymphangitis is an infection of lymph vessels. Lymph vessels are part of the immune system. They help carry infected fluids away from the site of an infection.

Causes  

Lymphangitis is caused by bacteria.

It starts with a bacterial skin infection. When the lymph vessels start to carry fluids away from the infection, the bacteria can move into the lymph vessels and begin to grow. The growth causes the infection.
