| bacterial vegetations | Lesions of bacterial endocarditis that form anywhere on the endocardium but preferentially on higher pressure and injured areas and particularly valves. They may also appear on arterial intima and in a patent ductus arteriosus and other areas of shunt inside and outside the heart. (05 Mar 2000) |
|---|---|
| bacterial virus | <microbiology, virology> A virus which infects bacteria and is usually species-specific. (09 Oct 1997) |
| bacterial wilt disease | <botany> A plant disease common in cucumber and muskmelon caused by the bacteria Erwinia tracheiphila which causes wilting and shriveling of the stems and leaves. (09 Oct 1997) |
| vaginosis, bacterial | Polymicrobial, non-specific vaginitis associated with positive cultures of gardnerella vaginalis and other anaerobic organisms and a decrease in lactobacilli. It remains unclear whether the initial pathogenic event is caused by the growth of anaerobes or a primary decrease in lactobacilli. (12 Dec 1998) |
| gene expression regulation, bacterial | Any of the processes by which cytoplasmic or intercellular factors influence the differential control of gene action in bacteria. (12 Dec 1998) |
| genes, bacterial | The genetic material of bacteria. (12 Dec 1998) |
| genes, structural, bacterial | DNA sequences that code for RNA and for the proteins required for the enzymatic and structural function of bacterial cells. (12 Dec 1998) |
| genome, bacterial | The complete gene complement contained in a single chromosome in a bacterium. (12 Dec 1998) |
| meningitis, bacterial | Meningitis caused by species of bacteria. (12 Dec 1998) |
| gram-negative bacterial infections | <microbiology> Infections caused by bacteria that show up as pink (negative) when treated by the gram-staining method. (12 Dec 1998) |
| gram-positive bacterial infections | <microbiology> Infections caused by bacteria that retain the crystal violet stain (positive) when treated by the gram-staining method. (12 Dec 1998) |
| RNA, bacterial | Ribonucleic acid in bacteria having regulatory and catalytic roles as well as involvement in protein synthesis. (12 Dec 1998) |
| 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) |
