  Lymphadenitis: Encyclopedia of Medicine   (Site not responding. Last check: 2007-10-10)
Lymphadenitis may be either generalized, involving a number of lymph nodes; or limited to a few nodes in the area of a localized infection.
Lymphadenitis is sometimes accompanied by lymphangitis, which is the inflammation of the lymphatic vessels that connect the lymph nodes.
Lymphadenitis in children often occurs in the neck area because these lymph nodes are close to the ears and throat, which are frequent locations of bacterial infections in children.

 Lymphadenitis - Definition, Description, Demographics, Causes and symptoms, Diagnosis, Treatment, Prognosis, Prevention
Lymphadenitis is marked by swollen lymph nodes that develop when the glands are overwhelmed by bacteria, virus, fungi, or other organisms.
Lymphadenitis is also referred to as lymph node infection, lymph gland infection, or localized lymphadenopathy.
The early symptoms of lymphadenitis are swelling of the nodes caused by a build-up of tissue fluid and an increased number of white blood cells resulting from the body's response to the infection.

 Lymphadenitis: Lymphatic Disorders: Merck Manual Home Edition
Lymphadenitis is inflammation of one or more lymph nodes, which usually become swollen and tender.
Lymphadenitis is almost always caused by an infection, which may be due to bacteria, viruses, protozoa, rickettsiae, or fungi.
When the cause cannot be identified easily, a biopsy (removal and examination of a tissue sample under a microscope) and culture may be needed to confirm the diagnosis and to identify the organism causing the infection.

Lymphadenitis is swelling of lymph nodes due to inflammation.
When the infection is of the lymph nodes themselves, it is called lymphadenitis, but when the infection is of the lymph channels, it is called lymphangitis.

It is hard to distinguish a high power view of lymphadenitis from normal lymph node tissue unless large numbers of eosinophils are present, as with a parasitic infestation, or if there are large numbers of neutrophils, such as with an acute bacterial infection.
In this slide, the diagnosis is easy as there are large numbers of neutrophils present--the small cells with multilobed nuclei and clear cytoplasm.

 Caseous Lymphadenitis - Managing with Formalin
Caseous Lymphadenitis is a fact of life in meat-goat herds.
Since laboratory tests for Caseous Lymphadenitis are far from perfect, especially on animals under six months of age, it is difficult for a producer to make sure that the goat being vaccinated has not already been exposed to the CL bacteria.
Most people who have Caseous Lymphadenitis abscesses in their herds refuse to acknowledge its existence because of the stigma it carries today, particularly when they are selling expensive breeding stock.

 Caseous Lymphadenitis   (Site not responding. Last check: 2007-10-10)
Caseous Lymphadenitis (CL) is a chronic infectious disease that affects goats and sheep worldwide.
There is no cure for Caseous Lymphadenitis and while there is a vaccine available, it is only efficient in preventing CL in sheep, not goats.
The bacteria can also survive for long periods of time in soil, bedding, or hay, so therefore the pus must be kept from falling onto the ground, and should be safely disposed of by flushing down a drain or by burning.
