| 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) |

| sexually transmitted diseases, bacterial | Bacterial diseases transmitted or propagated by sexual conduct. (12 Dec 1998) |
| 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) |
| 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) |
| accessory chromosome | A chromosome existing without its normal homologous chromosome; at the reduction division of gametogenesis an accessory chromosome is likely to be included in one daughter cell and not in the other, but may be lost completely by lagging behind on the equatorial plate. Synonym: monosome, odd chromosome, unpaired allosome, unpaired chromosome. (05 Mar 2000) |
| acentric chromosome | A fragment of a chromosome lacking a centromere and unable to attach to the mitotic spindle, therefore unable to take part in the division of a nucleus and randomly distributed in daughter cells. Synonym: acentric fragment. (05 Mar 2000) |
