Inflammation of the lymph nodes.
Infection of the lymph nodes by tuberculosis. Tuberculous infection of the cervical lymph nodes is scrofula.
Development of lesions in the lymph node characterized by infiltration of the cortex or paracortex by large collections of proliferating histiocytes and complete or, more often, incomplete necrosis of lymphoid tissue.
A species of gram-positive, asporogenous bacteria that was originally isolated from necrotic areas in the kidney of a sheep. It may cause ulcerative lymphangitis, abscesses, and other chronic purulent infections in sheep, horses, and other warm-blooded animals. Human disease may form from contact with infected animals.
Infections with bacteria of the genus CORYNEBACTERIUM.
A species of gram-positive, aerobic bacteria that causes granulomatous or ulcerating skin lesions in immunosuppressed persons. This organism owes its name to its requirement for growth of high levels of iron, conveniently supplied as blood, heme, or ferric ammonium citrate.
The part of a human or animal body connecting the HEAD to the rest of the body.
Disorders of the mediastinum, general or unspecified.
Infections with bacteria of the genus MYCOBACTERIUM.
They are oval or bean shaped bodies (1 - 30 mm in diameter) located along the lymphatic system.
Macrophages found in the TISSUES, as opposed to those found in the blood (MONOCYTES) or serous cavities (SEROUS MEMBRANE).
Common name for one of five species of small PARROTS, containing long tails.
A genus of gram-positive, aerobic bacteria. Most species are free-living in soil and water, but the major habitat for some is the diseased tissue of warm-blooded hosts.

Using fine needles (finer than 22-gauge) to remove tissue or fluid specimens from the living body for examination in the pathology laboratory and for disease diagnosis.
A self-limiting bacterial infection of the regional lymph nodes caused by AFIPIA felis, a gram-negative bacterium recently identified by the Centers for Disease Control and Prevention and by BARTONELLA HENSELAE. It usually arises one or more weeks following a feline scratch, with raised inflammatory nodules at the site of the scratch being the primary symptom.
Necrotizing inflammation of the CECUM ("typhlon" in Greek), sometimes spreading to the APPENDIX and/or the ILEUM. Symptoms include ABDOMINAL PAIN and DIARRHEA. Its pathogenesis is multifactorial. Typhlitis is often associated with NEUTROPENIA and chemotherapy in immunocompromised individuals (IMMUNOCOMPROMISED HOST).
Drugs used in the treatment of tuberculosis. They are divided into two main classes: "first-line" agents, those with the greatest efficacy and acceptable degrees of toxicity used successfully in the great majority of cases; and "second-line" drugs used in drug-resistant cases or those in which some other patient-related condition has compromised the effectiveness of primary therapy.
Diseases of the domestic or wild goat of the genus Capra.
An independent state in eastern Africa. Ethiopia is located in the Horn of Africa and is bordered on the north and northeast by Eritrea, on the east by Djibouti and Somalia, on the south by Kenya, and on the west and southwest by Sudan. Its capital is Addis Ababa.
Accumulation of purulent material in tissues, organs, or circumscribed spaces, usually associated with signs of infection.
A genus of achlorophyllic algae in the family Chlorellaceae, and closely related to CHLORELLA. It is found in decayed matter; WATER; SEWAGE; and SOIL; and produces cutaneous and disseminated infections in various VERTEBRATES including humans.
A species of gram-positive, aerobic bacteria that produces TUBERCULOSIS in humans, other primates, CATTLE; DOGS; and some other animals which have contact with humans. Growth tends to be in serpentine, cordlike masses in which the bacilli show a parallel orientation.
A non-tuberculous mycobacterium causing cervical lymphadenitis in children. It very rarely causes pulmonary disease, and is believed to be non-pathogenic in animals.
Removal and examination of tissue obtained through a transdermal needle inserted into the specific region, organ, or tissue being analyzed.
A rapid-growing, nonphotochromogenic species that is potentially pathogenic, producing lesions of lung, bone, or soft tissue following trauma. It has been found in soil and in injection sites of humans, cattle, and cold-blooded animals. (Dorland, 28th ed)
The historic designation for scrofula (TUBERCULOSIS, LYMPH NODE). The disease is so called from the belief that it could be healed by the touch of a king. This term is used only for historical articles using the name "king's evil", and is to be differentiated from scrofula as lymph node tuberculosis in modern clinical medicine. (From Webster, 3d ed)
Works containing information articles on subjects in every field of knowledge, usually arranged in alphabetical order, or a similar work limited to a special field or subject. (From The ALA Glossary of Library and Information Science, 1983)
NATIONAL LIBRARY OF MEDICINE service for health professionals and consumers. It links extensive information from the National Institutes of Health and other reviewed sources of information on specific diseases and conditions.
Transfer of a neoplasm from its primary site to lymph nodes or to distant parts of the body by way of the lymphatic system.
Invasion of the host RESPIRATORY SYSTEM by microorganisms, usually leading to pathological processes or diseases.
Individual's rights to obtain and use information collected or generated by others.
A subspecialty of internal medicine concerned with the study of the physiology and diseases of the digestive system and related structures (esophagus, liver, gallbladder, and pancreas).
A quantitative measure of the frequency on average with which articles in a journal have been cited in a given period of time.
A publication issued at stated, more or less regular, intervals.
A broad family of synthetic organosiloxane polymers containing a repeating silicon-oxygen backbone with organic side groups attached via carbon-silicon bonds. Depending on their structure, they are classified as liquids, gels, and elastomers. (From Merck Index, 12th ed)
Implants used to reconstruct and/or cosmetically enhance the female breast. They have an outer shell or envelope of silicone elastomer and are filled with either saline or silicone gel. The outer shell may be either smooth or textured.
Organic siloxanes which are polymerized to the oily stage. The oils have low surface tension and density less than 1. They are used in industrial applications and in the treatment of retinal detachment, complicated by proliferative vitreoretinopathy.
Polymers of silicone that are formed by crosslinking and treatment with amorphous silica to increase strength. They have properties similar to vulcanized natural rubber, in that they stretch under tension, retract rapidly, and fully recover to their original dimensions upon release. They are used in the encapsulation of surgical membranes and implants.
A relatively small nodular inflammatory lesion containing grouped mononuclear phagocytes, caused by infectious and noninfectious agents.
A cyst in the neck caused by persistence of portions of, or by lack of closure of, the primitive thyroglossal duct. (Dorland, 27th ed)

The ability of lymphoid cells to mount a humoral or cellular immune response when challenged by antigen.
IMMUNOGLOBULINS on the surface of B-LYMPHOCYTES. Their MESSENGER RNA contains an EXON with a membrane spanning sequence, producing immunoglobulins in the form of type I transmembrane proteins as opposed to secreted immunoglobulins (ANTIBODIES) which do not contain the membrane spanning segment.
