glucose-6-phosphate-dependent pyruvate kinase in streptococcus mutans.	pyruvate kinase of streptococcus mutans jc 2 had an absolute and specific requirement for glucose-6-phosphate. inorganic phosphate was a strong inhibitor. the enzyme required k+ or nh4+ and mg2+ or mn2+. s. mutans fil and e 49, streptococcus bovis atcc 9809, and streptococcus salivarius atcc 13419 had also glucose-6-phosphate-dependent pyruvate kinases, whereas streptococcus sanguis nctc 10904 had an enzyme activated by fructose-1,6-diphosphate.	1975	240810
growth of several cariogenic strains of oral streptococci in a chemically defined medium.	a chemically defined medium in which streptococcus mutans strains aht, bht, gs-5, jc-2, ingbritt, at6t, at9t, 6715, and omz-176 and streptococcus salivarius strain hht grew rapidly to high turbidities was formulated. maximal turbidities of each strain were observed after 8 to 12 h of aerobic growth. the subsequent transfer of exponentially growing cells into fresh medium resulted in growth at the same rate without lag. growth of these strains occurred with rates at least one-half of those observ ...	1975	1091546
amino acid requirements of streptococcus mutans and other oral streptococci.	the amino acid requirements of streptococcus mutans strains aht, omz-61, fa-1, bht, gs-5, jc-2, ingbritt, at6t, omz-176, 6715, streptococcus salivarius hht, streptococcus sanguis omz-9, and strain 72x46 were determined in a chemically defined medium. when grown anaerobically in the presence of sodium carbonate (or bicarbonate for a few strains), few amino acids were required. all strains tested required cystine (or cystine) as a nutrient. three strains (s. mutans omz-176, fa-1, and bht) required ...	1975	1091547
purification and characterization of two bacteriocins from streptococcus faecium.	two bacteriocins were found in the supernatant fluid and in an extract of streptococcus faecium strain ei. the small soluble enterocin eia represented more than 90% of the total activity in the supernatant fluid, and was purified 400-fold by ammonium sulphate fractionation, gel filtration on sephadex g-75 and chromatography on deae-cellulose. enterocin eib, with a particle weight greater than 4 x 10(6), was the predominant type in the extract. it was released in appreciable quantities after brea ...	1975	1097585
[studies on the relationship of temperent phages and bacteriocines of streptococcus faecium (author's transl)].	two bacteriocins (enterocin e1a and e1b) as well as a complete bacteriophage (pe1) were produced by streptococcus faecium strain e1. although the phage could be demonstrated by electron microscopy it was not possible to observe phages or phage-like particles in the purified preparation of the large enterocin e1b. phage pe1 had a much smaller activity spectrum than that of enterocin e1a and e1b, inhibiting only one strain of streptococcus faecium and one strain of streptococcus salivarius. the en ...	1975	1101576
bacterial interference by streptococcus salivarius.	a strain of streptococcus salivarius, recognized in a throat culture because of its inhibition of the growth of a species of corynebacterium, was studied in vitro to determine its antagonistic effects agains various other bacteria. it was found to be inhibitory to anaerobic gram-positive cocci, streptococci belonging to lancefields groups a, c, f, and g, and corynebacterium diphtheriae, c. hofmanii, and c. xerosis.	1975	1155368

[synthesis of extracellular polysaccharides by various forms of streptococcus salivarius].	streptococcus salivarius synthesizes extracellular polysaccharides (eps) from saccharose under aerobic and anaerobic conditions. under aerobic conditions primarily soluble fructanes are formed. there are no differences between the eps synthesized by r- and s-forms under aerobic conditions; anaerobically the s-forms produce more eps and more fructane than the r-forms. as compared to streptococcus mutans, the streptococcus salivarius produces considerably more fructane and insoluble glucane under ...	1977	269074
changes in the microflora and physiology of the anterior intestinal tract of pigs weaned at 2 days, with special reference to the pathogenesis of diarrhea.	the gastrointestinal microflora and gastric physiology of piglets weaned at 2 days was compared with that of piglets allowed to continue sucking the sow. although there was a significantly higher count of escherichia coli in the stomach, duodenum, and jejunum of the early-weaned compared with sow-reared pigs, these differences were not detectable in samples from the ileum. there were no quantitative differences in lactobacilli and in streptococci between the two treatments. lactobacillus ferment ...	1977	22488
adherence of veillonella species mediated by extracellular glucosyltransferase from streptococcus salivarius.	the effect of extracellular products from streptococcus salivarius on sucrose-dependent adherence to smooth surfaces by other oral bacteria was studied in vitro. strains of streptococcus mitis, streptococcus pyogenes, and veillonella parvula without innate ability to adhere to a steel wire were able to do so when incubated with sucrose and cell-free culture fluid from s. salivarius strains 9759, 25975, cnii, and mepi. these culture fluids synthesized more adherent material and water-insoluble gl ...	1977	591064
tween 80 effect on glucosyltransferase synthesis by streptococcus salivarius.	streptococcus salivarius (atcc 25975) produced very low or nondetectable amounts of the extracellular enzyme glucosyltransferase (gtase) when grown in a chemically defined medium. the addition of tween 80 to this medium resulted in the production of markedly enhanced levels of the enzyme. oleic acid, the methyl ester of oleic acid, and sucrose each could not substitute for tween 80 in this regard. the surfactant had no direct activating effect on performed enzyme activity. tween 80 also stimulat ...	1978	618839

bacteria associated with the gastric epithelium of neonatal pigs.	light and electron microscopy showed lactobacilli and, to a lesser degree, streptococci to be closely associated with the squamous area of the pig stomach known as the pars esophagea. several different types of extracellular layers were seen on bacteria attached to the epithelial surface. the total number of bacteria per square centimeter did not change with age up to 10 days, and there was no effect of weaning at 2 days. lactobacillus fermentum, l. salivarius, and streptococcus salivarius were ...	1978	637551
a study of the interaction between oral streptococci and hard surfaces.	a rotating disc method was used to compare the tendencies of two oral streptococci to deposit on to glass and polystyrene surfaces from electrolyte solutions of varying ionic strength. streptococcus salivarius had a greater tendency to deposit than had streptococcus mitior under these condition. in addition to the balance of van der waals' forces of attraction and electrostatic forces of repulsion, it is suggested that the adsorption to the glass and polystyrene surfaces of material present in t ...	1978	641524
inhibitory effects of extracellular products from oral bacteria on human fibroblasts and stimulated lymphocytes.	extracellular products of 12 strains of streptococcus mutans and 5 additional species of oral bacteria were analyzed for their ability to inhibit proliferation of fibroblastoid cells (hela and av3) and blast transformation of human peripheral blood lymphocytes obtained from normal individuals. products from s. mutans strains aht and bht, streptococcus intermedius, and actinomyces viscosus inhibited [3h]thymidine uptake by fibroblastoid cells and phytohemagglutinin-stimulated lymphocytes. product ...	1978	689736
improved immunoadsorption procedure with anion-exchange bacterial cell columns.	bacterial cell columns for immunoadsorption were prepared with streptococcus cells and triethylaminoethyl cellulose (cellex-t) matrix material as a model system. good column flow properties and satisfactory retention of the cells were obtained with ratios as high as 2 ml of packed cells/3 g dry weight of cellulose. anion-exchange fractionation of whole serum by the cellex-t was prevented by using 0.25 m nacl in the developing buffer. antibodies were adsorbed directly from whole serum and recover ...	1978	351066
factors affecting the aggregation of actinomyces naeslundii during growth and in washed cell suspensions.	various factors affecting the aggregation of actinomyces naeslundii strain 12104 were studied. when the ph of glucose-supplemented growth medium fell below 5.5, the cells aggregated and formed microbial masses which tenaciously adhered to the culture vessels. when the organism was cultured in the same medium in the absence of glucose, maximum growth was reduced and the final culture ph values remained above 6.5, but the cells were more dispersed and nonadherent. adjusting the final ph of these c ...	1978	30700
extractability of cell wall polysaccharide from lactobacilli and streptococci by autoclaving and by dilue acid.	autoclaving cell wall of streptococcus mutans ingbritt for 15 min under the rantz and randall conditions released one-tenth of the total cell wall carbohydrate, whereas two-thirds was extracted after autoclaving for 180 min. the extract contained the serotype c-specific antigen but lacked the lipoteichoic acid component extracted when whole cells were autoclaved. autoclaving cell wall preparations from other strains of s. mutans and also streptococcus salivarius and streptococcus mitis in 0.85% ...	1978	32140
genital occurrence of oral microbiota.	recent studies indicate that tonsillar gonococcal infection or colonization is fairly common. carriage rates of about 8% have been found. these studies also indicate that oro-genital contacts are common. since very little is known about the amount of oral microbiota transmitted to the genitals, we have studied the occurrence of oral streptococci and neisseria species in urethra and cervix. among 128 patients attending an std-clinic we found 10 carriers of oral streptococci, one streptococcus mit ...	1978	82332
