autolytic formation of protoplasts (autoplasts) of streptococcus faecalis 9790: release of cell wall, autolysin, and formation of stable autoplasts. | a system for the formation of apparently wall-free protoplasts from exponential-phase cells of streptococcus faecalis atcc 9790 in the absence of added lytic enzymes was developed. exponential-phase cells suspended in 0.04 m ammonium acetate, ph 6.7, 1 mm magnesium acetate, and 0.5 m sucrose become osmotically fragile within 1 to 1.5 h due to the action of the native, autolytic enzyme on the cell wall peptidoglycan. however, maximal cell wall loss occurred much more slowly, being complete only a ... | 1974 | 4133354 |
effect of inhibition of deoxyribonucleic acid and protein synthesis on the direction of cell wall growth in streptococcus faecalis. | selective inhibition of protein synthesis in streptococcus faecalis (atcc 9790) was accompanied by a rapid and severe inhibition of cell division and a reduction of enlargement of cellular surface area. continued synthesis of cell wall polymers resulted in rapid thickening of the wall to an extent not seen in exponential-phase populations. thus, the normal direction of wall growth was changed from a preferential feeding out of new wall surface to that of thickening existing cell surfaces. howeve ... | 1974 | 4133352 |

morphokinetic reaction of cells of streptococcus faecalis (atcc 9790) to specific inhibition of macromolecular synthesis: dependence of mesosome growth on deoxyribonucleic acid synthesis. | the application of quantitative electron microscopy to thin sections of cells of streptococcus faecalis specifically inhibited for deoxyribonucleic acid (dna), ribonucleic acid, and protein synthesis shows that septal mesosomes (i) increase in size when protein synthesis is inhibited by at least 80% while dna synthesis proceeds at no less than 50% of the control rate and (ii) decrease in size when dna synthesis is inhibited 50% or more during the initial 10 min of treatment. this indicates that ... | 1972 | 4110926 |
morphokinetic reaction of streptococcus faecalis (atcc 9790) cells to the specific inhibition of macromolecular synthesis: nucleoid condensation on the inhibition of protein synthesis. | in glutaraldehyde-prefixed exponential-phase cells of streptococcus faecalis the nucleoid is "frozen" in a dispersed configuration. exposure of exponential-phase cells to threonine starvation or to antibiotics inhibiting protein synthesis resulted in progressive condensation of nucleoid fibrils producing an expanding central nucleoid zone or pool. the condensation of the nucleoid was observed to occur at a rate directly proportional to the rate of inhibition of protein synthesis. however, the ex ... | 1972 | 4110925 |

microbial adhesion to fibronectin in vitro correlates with production of endocarditis in rabbits. | microbial adhesion to the constituents of nonbacterial thrombotic endocarditis (nbte) is an important early event in the pathogenesis of infective endocarditis. fibronectin is a ubiquitous mammalian glycoprotein with diverse functions which binds to certain bacteria but not to others. in this study, we determined that fibronectin is present on the surface of nbte (after catheter-induced aortic valve trauma) but not on normal rabbit cardiac valvular endothelium. the adhesion of various bacteria a ... | 1985 | 3936047 |
induction of surface exclusion (entry exclusion) by streptococcus faecalis sex pheromones: use of monoclonal antibodies to identify an inducible surface antigen involved in the exclusion process. | the streptococcus faecalis plasmid pcf-10 is representative of a class of plasmids that enables its host cells to respond to sex pheromones produced by other s. faecalis cells. the pheromone response has been previously shown to result in increased conjugal plasmid transfer, cell clumping, and multiple cell-surface antigenic changes. to test for other effects of pheromone induction, cells carrying pcf-10 were used as recipients in matings with an isogenic donor strain carrying a derivative of pc ... | 1985 | 3936037 |
enzyme release of antigen from streptococcus faecalis and listeria monocytogenes cross-reactive with lancefield group g typing reagents. | enzyme extraction methods are commonly used to release antigen for lancefield serogrouping of streptococci. recently, up to 47% of enterococci have been found to possess antigens cross-reactive with both the group d and the group g grouping reagents. we investigated whether the organisms had recently emerged or whether changes in extraction methods (enzyme extraction) have resulted in our awareness of their existence. we found that approximately 20% of our enterococcal isolates released material ... | 1985 | 3935666 |
comparison of american microscan dry and frozen microdilution trays. | this study compared the american microscan frozen microdilution tray and dehydrated microdilution tray. a total of 153 gram-negative and 106 gram-positive isolates were tested concurrently on both tray types and read visually. very major and major antimicrobial susceptibility discrepancies amounted to 1.0% of all results, and minor discrepancies amounted to 0.4% of all results. the biochemical discrepancy rate for gram-negative organisms was 1.3%, resulting in no identification errors either at ... | 1985 | 3935659 |
