| 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) |

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 toxin | Any intracellular or extracellular toxin formed in or elaborated by bacterial cells. (05 Mar 2000) |
| chromosomes, bacterial | Structures within the nucleus of bacterial cells consisting of or containing DNA, which carry genetic information essential to the cell. (12 Dec 1998) |
|---|---|
| photosynthetic reaction centre, bacterial | A system consisting of proteins and cofactors which acts as a light-driven electron pump across the photosynthetic membrane of photosynthetic bacteria. (12 Dec 1998) |
| conjunctivitis, bacterial | Purulent infections of the conjunctiva by several species of gram-negative, gram-positive, or acid-fast organisms. Some of the more commonly found genera causing conjunctival infections are haemophilus, streptococcus, neisseria, and chlamydia. (12 Dec 1998) |
| pneumonia, bacterial | Pneumonia caused by various species of bacteria. Bacterial pneumonia commonly results from bronchogenic spread of infection following microaspiration of secretions. The largest category of this disease arises from community-acquired pneumonias. (12 Dec 1998) |
| polysaccharides, bacterial | Polysaccharides found in bacteria and especially bacterial capsules. (12 Dec 1998) |
| progressive bacterial synergistic gangrene | Undermining ulcer of the skin and subcutaneous tissues, usually following an operation, caused by a synergistic interaction between microaerophilic nonhemolytic streptococci and aerobic haemolytic staphylococci. Synonym: Meleney's gangrene, progressive bacterial synergistic gangrene. (05 Mar 2000) |

| skin diseases, bacterial | Skin diseases caused by bacteria. (12 Dec 1998) |
| spores, bacterial | Heat and stain resistant, metabolically inactive bodies formed within the vegetative cells of bacteria of the genera bacillus and clostridium. (12 Dec 1998) |
| subacute bacterial endocarditis | Subacute bacterial endocarditis is usually due to Streptococcus viridans or S. Fecalis. (05 Mar 2000) |
| DNA, bacterial | Deoxyribonucleic acid that makes up the genetic material of bacteria. (12 Dec 1998) |
| 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) |

| 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) |
