Negative Results
|
D000076723 |
[Subject matter related to research studies in which the data do not demonstrate any clear evidence of effect, especially if an effect was expected.

Negative Staining
|
D016624 |
[The technique of washing tissue specimens with a concentrated solution of a heavy metal salt and letting it dry. The specimen will be covered with a very thin layer of the metal salt, being excluded in areas where an adsorbed macromolecule is present. The macromolecules allow electrons from the beam of an electron microscope to pass much more readily than the heavy metal; thus, a reversed or negative image of the molecule is created.

Negative-Pressure Wound Therapy
|
D054843 |
[The application of a vacuum across the surface of a wound through a foam dressing cut to fit the wound. This removes wound exudates, reduces build-up of inflammatory mediators, and increases the flow of nutrients to the wound thus promoting healing.

Negative-Sense RNA Viruses
|
D000086103 |
[RNA viruses that have their genetic material encoded in the form of single-stranded, negative-sense RNA. Unlike RETROVIRUSES they do not employ DNA intermediates in their life-cycle

Negativism
|
D009341 |
[State of mind or behavior characterized by extreme skepticism and persistent opposition or resistance to outside suggestions or advice. (APA, Thesaurus of Psychological Index Terms, 1994)

Neglecta
|
D000086242 |
[A genus of gram-positive, anaerobic bacteria in the order CLOSTRIDIALES and phylum FIRMICUTES. This genus is known for the type species Neglecta timonensis which was discovered in the stool of a patient with DIABETES MELLITUS, TYPE 2.

Neglected Diseases
|
D058069 |
[Diseases that are underfunded and have low name recognition but are major burdens in less developed countries. The World Health Organization has designated six tropical infectious diseases as being neglected in industrialized countries that are endemic in many developing countries (HELMINTHIASIS; LEPROSY; LYMPHATIC FILARIASIS; ONCHOCERCIASIS; SCHISTOSOMIASIS; and TRACHOMA).

Negotiating
|
D017008 |
[The process of bargaining in order to arrive at an agreement or compromise on a matter of importance to the parties involved. It also applies to the hearing and determination of a case by a third party chosen by the parties in controversy, as well as the interposing of a third party to reconcile the parties in controversy.

Neisseria
|
D009343 |
[A genus of gram-negative, aerobic, coccoid bacteria whose organisms are part of the normal flora of the oropharynx, nasopharynx, and genitourinary tract. Some species are primary pathogens for humans.

Neisseria cinerea
|
D042804 |

|
Neisseria elongata
|
D042805 |
[A species of gram-negative, aerobic BACTERIA consisting of short chains of rods. It has been isolated from the PHARYNX of healthy individuals and patients with ENDOCARDITIS. There are several recognized subspecies.

Neisseria gonorrhoeae
|
D009344 |
[A species of gram-negative, aerobic bacteria primarily found in purulent venereal discharges. It is the causative agent of GONORRHEA.

|
Neisseria lactamica
|
D042806 |
[A species of gram-negative, aerobic BACTERIA commonly found in the NASOPHARYNX of infants and children, but rarely pathogenic. It is the only species to produce acid from LACTOSE.

|
Neisseria meningitidis
|
D009345 |
[A species of gram-negative, aerobic BACTERIA. It is a commensal and pathogen only of humans, and can be carried asymptomatically in the NASOPHARYNX. When found in cerebrospinal fluid it is the causative agent of cerebrospinal meningitis (MENINGITIS, MENINGOCOCCAL). It is also found in venereal discharges and blood. There are at least 13 serogroups based on antigenic differences in the capsular polysaccharides; the ones causing most meningitis infections being A, B, C, Y, and W-135. Each serogroup can be further classified by serotype, serosubtype, and immunotype.

Neisseria meningitidis, Serogroup A
|
D038381 |
[Strains of Neisseria meningitidis responsible for most outbreaks of meningococcal disease in Western Europe and the United States in the first half of the 20th century. They continue to be a major cause of disease in Asia and Africa, and especially localized epidemics in Sub-Sahara Africa.

|
Neisseria meningitidis, Serogroup B
|
D038541 |
[Strains of Neisseria meningitidis which are the most common ones causing infections or disease in infants. Serogroup B strains are isolated most frequently in sporadic cases, and are less common in outbreaks and epidemics.
] |
|
Neisseria meningitidis, Serogroup C
|
D038542 |
[Strains of Neisseria meningitidis responsible for most sporadic cases in teenagers and almost all outbreaks of disease in this age group. These strains are less common in infants.

Neisseria meningitidis, Serogroup W-135
|
D038582 |
[Strains of Neisseria meningitidis found mostly in Africa.

|
Neisseria meningitidis, Serogroup Y
|
D038581 |
[Strains of Neisseria meningitidis which, in the United States, causes disease in mostly adults and the elderly. Serogroup Y strains are associated with PNEUMONIA.

Neisseria mucosa
|
D042807 |
[A species of gram-negative, aerobic BACTERIA, found in the human NASOPHARYNX and in the normal flora of the respiratory tissues in DOLPHINS. It is occasionally pathogenic for humans and pathogenic for MICE. (Bergey's Manual of Systemic Bacteriology, 1st edition, p295)
