| BPI | bacterial permeability-increasing [protein]; Basic Personality Inventory; beef-pork insulin; blood p... |
|---|---|
| BV | bacitracin V; bacterial vaginosis; biological value; blood vessel; blood volume; bronchovesicular |
| F- | a bacterial cell lacking an F plasmid |
| F+ | a bacterial cell having an F plasmid |
| GBIA | Guthrie bacterial inhibition assay |
| endocarditis, subacute bacterial | Infection of the endocardium caused by species of streptococcus. This condition does not produce metastatic foci and if untreated may take up to a year to be fatal. (12 Dec 1998) |
|---|---|
| transformation, bacterial | The heritable modification of the properties of a competent bacterium by DNA from another bacterial strain. (12 Dec 1998) |
| eye infections, bacterial | Infections in the inner or external eye caused by microorganisms belonging to several families of bacteria. Some of the more common genera found are haemophilus, neisseria, staphylococcus, streptococcus, and chlamydia. (12 Dec 1998) |
| fibrous bacterial viruses | Deoxyribonucleoproteins that "infect" and replicate in Gram-negative bacteria having sex pili and that, unlike bacteriophage, are released from infected bacteria without damage to the cell; they seem to be of two kinds, one of which has a specificity for F pili and the other for I pili. Synonym: fibrous bacterial viruses. (05 Mar 2000) |
| filamentous bacterial viruses | Deoxyribonucleoproteins that "infect" and replicate in Gram-negative bacteria having sex pili and that, unlike bacteriophage, are released from infected bacteria without damage to the cell; they seem to be of two kinds, one of which has a specificity for F pili and the other for I pili. Synonym: fibrous bacterial viruses. (05 Mar 2000) |
| fimbriae, bacterial | Thin, hairlike appendages, 1 to 20 microns in length and often occurring in large numbers, present on the cells of gram-negative bacteria, particularly enterobacteriaceae and neisseria. Unlike flagella, they do not possess motility, but being protein (pilin) in nature, they possess antigenic and haemagglutinating properties. They are of medical importance because some fimbriae mediate the attachment of bacteria to cells via adhesins (adhesins, bacterial). Bacterial fimbriae refer to common pili, to be distinguished from the preferred use of "pili", which is confined to sex pili (pili, sex). (12 Dec 1998) |
| luminescence, bacterial | The emission of light by bacteria. It is applied to studies on bacterial viability, metabolism, genetics, adhesiveness, and other physiological properties. (12 Dec 1998) |
| abscess, skin | Medical term for a common boil. (12 Dec 1998) |
| allergy skin test | Test done on the skin to identify the allergy substance (allergen) triggering the allergic reaction. A small amount of the suspected allergy substance is placed on the skin. The skin is then gently scratched through the small drop with a special sterile needle. If the skin reddens and, more importantly, swells, then allergy to that substance is probable. (12 Dec 1998) |
| alligator skin | <dermatology> A group of cutaneous disorders characterised by increased or aberrant keratinisation, resulting in noninflammatory scaling of the skin. Many different metaphors have been used to describe the appearance and texture of the skin in the various types and stages of ichthyosis, for example alligator, collodion, crocodile, fish and porcupine skin. most ichthyoses are genetically determined, while some may be acquired and develop in association with various systemic diseases or be a prominent feature in certain genetic syndromes. The term is commonly used alone to refer to i. Vulgaris. (18 Nov 1997) |
| appendages of skin | The hairs, nails, and sweat, sebaceous, and mammary glands. (05 Mar 2000) |
| aspergillus antigen skin test | <investigation> An antigen, prepared from aspergillus, is injected into the skin. In 48 to 72 hours the site is read as positive or negative. A positive skin test (inflammation at the test site) indicates prior exposure to aspergillus and therefore a risk for developing aspergillosis. (27 Sep 1997) |
| bronzed skin | The dark skin in Addison's disease. (05 Mar 2000) |
| calipers, skin | Calipers are instruments used to measure the diameter of an object. (The word calipers is a corruption of caliber ). The skin fold thickness in several parts of the body can be measured with calipers, a metal or plastic tool similar to a compass. This is done in medicine and physical anthropology. (12 Dec 1998) |
| cancer, skin | Cancer of the outer surface of the body. The most common cancer in the U.S. There are many types of skin cancer. Ultraviolet light from sunlight is the main cause of skin cancer. Unexplained changes in the appearance of the skin, lasting longer than 2 weeks, should be evaluated by a doctor. The cure rate for skin cancer could be 100% if all skin cancers were brought to a doctor's attention before they had a chance to spread. (12 Dec 1998) |
