| bacterial endospore | <microbiology> A dormant body which certain Gram-positive bacteria can develop within them under conditions of stress (like lack of nutrients), which is highly resistant to harsh environmental conditions and which can develop into a new, live bacterium once conditions are good again. (09 Oct 1997) |
|---|---|
| bacterial flagella | <microbiology> Thin filaments composed of flagellin sub units that are rotated by the basal motor assembly and act as propellors. If rotating anticlockwise (as viewed from the flagellar tip) the bacterium moves in a straight path, if clockwise the bacterium tumbles. (18 Nov 1997) |
| bacterial food poisoning | A term commonly used to refer to conditions limited to enteritis or gastroenteritis (excluding the enteric fevers and the dysenteries) caused by bacterial multiplication per se or by a soluble bacterial exotoxin. (05 Mar 2000) |
| bacterial growth | Growth of a bacterial culture either by increase in cell material or cell number. (05 Mar 2000) |
| bacterial interference | The condition in which colonization by one bacterial strain prevents colonization by another strain. (05 Mar 2000) |
| bacterial outer membrane proteins | Proteins isolated from the outer membrane of bacteria. (12 Dec 1998) |
| bacterial peliosis | A bacterial infection of haemorrhagic cysts of the liver, spleen, or lymph nodes, seen in immunocompromised persons, caused by Rochalimaea henselae. (05 Mar 2000) |
| bacterial pericarditis | Pericarditis produced by bacterial infection. (05 Mar 2000) |
| bacterial physiology | Physiological processes and activities of bacteria. (12 Dec 1998) |
| bacterial plaque | In dentistry, a mass of filamentous microorganisms and large variety of smaller forms attached to the surface of a tooth which, depending on bacterial activity and environmental factors, may give rise to caries, calculus, or inflammatory changes in adjacent tissue. Synonym: dental plaque, mucous plaque, mucinous plaque. (05 Mar 2000) |
| bacterial pneumonia | Infection of the lung with any of a large variety of bacteria, especially Streptococcus pneumoniae(pneumococcus). (05 Mar 2000) |
| bacterial proteins | Proteins found in any species of bacterium. (12 Dec 1998) |
| bacterial toxin | Any intracellular or extracellular toxin formed in or elaborated by bacterial cells. (05 Mar 2000) |
| bacterial toxins | Toxic substances formed in or elaborated by bacteria; they are usually proteins with high molecular weight and antigenicity; some are used as antibiotics and some to skin test for the presence of or susceptibility to certain diseases. (12 Dec 1998) |
| bacterial transformation | <microbiology> A genetics lab procedure where bacteria are induced to accept and incorporate into their genome foreign pieces of cell-less, isolated DNA, often in the form of a plasmid. The DNA to be introduced usually contains a selectable marker so that the bacteria which successfully incorporate the DNA can be selected for. (09 Oct 1997) |
