antipseudomonal activity of alpha-sulfoaminopenicillins.a series of penicillins characterized by the presence of a sulfoamino or a modified sulfoamino group in the side chain was subjected to in vitro antimicrobial screening tests. although the most potent members of the series were less active than benzylpenicillin against gram-positive bacteria and comparably active against most gram-negative bacteria, they were, on the average, 8 to 16 times more effective against strains of pseudomonas aeruginosa. in other comparative laboratory tests against p. ...19694389660

malate utilization by a group d streptococcus: physiological properties and purification of an inducible malic enzyme.growth of streptococcus faecalis in the presence of l-malate resulted in the induction of a "malic enzyme" [l-malate:nicotinamide adenine dinucleotide (nad) oxidoreductase (decarboxylating), e.c. 1.1.1.39]. synthesis of the malic enzyme did not appear to be subject to catabolite repression by intermediate products of glucose or fructose dissimilation. however, malate utilization was inhibited during growth in the presence of glucose or fructose. the purified enzyme was specific for malate as sub ...19694306540

biochemical changes in serum of pure and mixed streptococcus faecalis and bacillus subtilis infections in rats.rats inoculated with streptococcus faecalis developed endocarditis and demonstrated a 6- to 30-fold increase in aldolase, isocitric dehydrogenase, phosphohexose isomerase, and lactic dehydrogenase. the animals infected with bacillus subtilis did not develop overt disease nor significant increases in enzyme activities, but viable organisms were recovered at 2 weeks. rats inoculated with mixed culture of these organisms showed a 2- to 10-fold increase of enzyme activities without evidence of patho ...19694189998

phospholipids of streptococcus faecalis.autoradiograms of total lipid extracts from streptococcus faecalis atcc 9790, harvested in the stationary phase from a medium containing (32)p-orthophosphate, showed six major spots. the corresponding compounds were identified as diphosphatidylglycerol (possibly with a penta acyl structure); phosphatidylglycerol; a provisionally identified mixture of alanylphosphatidylglycerol and of the 2'-lysyl-derivative of phosphatidylglycerol; the 3'-lysyl-derivative of phosphatidylglycerol, probably togeth ...19704321329

purificationa and properties of a fructose-1,6-diphosphate-activated lactate dehydrogenase from streptococcus faecalis.an l-(+)-lactate dehydrogenase was purified approximately 35-fold from crude extracts of streptococcus faecalis. the purified enzyme had an absolute and specific requirement for fructose-1,6-diphosphate (fdp) for catalytic activity. the concentration of fdp required for 50% maximal activity was about 0.045 mm. the activator was bound to the enzyme more effectively at ph 5.8 than it was at a neutral or alkaline ph. activation appeared to involve a conformational change in the enzyme which made th ...19704314543

action of bacterial growth on the sarcoplasmic and urea-soluble proteins from muscle. i. effects of clostridium perfringens, salmonella enteritidis, achromobacter liquefaciens, streptococcus faecalis, and kurthia zopfi.comparisons of the starch-gel patterns of uninoculated aseptic control samples from rabbit and pig muscle with similar samples inoculated and incubated with clostridium perfringens, salmonella enteritidis, achromobacter liquefaciens, and kurthia zopfii were made. results indicated that c. perfringens caused extensive alteration in the proteins or enzymes, or both, of the sarcoplasmic fraction of porcine muscle, whereas s. enteritidis and s. faecalis caused complete breakdown of only myoglobin. n ...19704318570

microbiological aspects of ethylene oxide sterilization. ii. microbial resistance to ethylene oxide.the death rate kinetics of several sporeforming and nonsporeforming microorganisms, including radiation-resistant cocci, were determined by exposing them to a mixture of ethylene oxide and dichlorodifluoromethane (500 mg of ethylene oxide per liter, 30 to 50% relative humidity, and 54.4 c). spore survivor curves obtained from tests of inoculated and exposed hygroscopic and nonhygroscopic carriers showed that the spores of bacillus subtilis var. niger are more resistant to ethylene oxide than are ...19705415211

malate utilization by a group d streptococcus: regulation of malic enzyme synthesis by an inducible malate permease.induction of an nicotinamide adenine dinucleotide-specific malic enzyme and a malate entry system permits streptococcus faecalis to grow at the expense of malate. evidence is presented which shows that biosynthesis of the permease, but not of the malic enzyme, is subject to catabolite repression by glucose. in contrast to the malic enzyme, the catalytic function of the entry system does not appear to be inhibited by intermediate products of glycolysis. although the induction of the entry system ...19705437724

fecal streptococci on barley and malt kernels and instant malted milk powder.among 500 barley kernels, tested singly, 1.8% (9 kernels) were positive for fecal streptococci. among 800 malt kernels, tested singly by the same procedure, 68% (540 kernels) were positive for fecal streptococci. in unsulfured and sulfured malts, 67 and 68% of the kernels, respectively, were positive for these bacteria. fecal streptococci were also isolated by an enrichment procedure from two brands of instant malted milk powder sold in supermarkets. seventy randomly picked isolates from malts w ...19704991404
early changes in the ultrastructure of streptococcus faecalis after amino acid starvation.thin sections of streptococcus faecalis (atcc 9790) starved of one essential amino acid (threonine or valine) initially show rapid increases in (i) cell wall thickness, (ii) the apparent size of the central nucleoid region, and (iii) mesosomal membranes. the most rapid increases in all three variables occurred during the first 1 to 2 hr of starvation. after this initial period, the rates progressively decreased over the 20-hr observation period. during threonine starvation, the mesosomal membran ...19704987306
model for cell wall growth of streptococcus faecalis.in exponentially growing and dividing cells of streptococcus faecalis, it is proposed that the leading edge of the annularly closing cross wall is the point of extension for both cross wall and peripheral wall. peripheral wall extension is thought to be produced by the separation or splitting of the cross wall at its junction with peripheral wall. this results in the pushing of the equatorial wall bands, found on s. faecalis walls, to subsequatorial positions. these bands therefore mark the sepa ...19704984078

bacteriophage active against the lactic acid beverage-producing bacterium lactobacillus casei.a virulent bacteriophage which causes a decrease in acid production during fermentation of a lactic acid beverage named yakult with lactobacillus casei was isolated from the abnormal fermentation tank and named pl-1. l. casei s strain was the exclusive host cell among 18 lactic acid bacteria tested. the plaque was round with an average diameter of about 0.5 mm. it exhibited serological cross-reaction with previously isolated j1 phage. under an electron microscope, the phage had a spermatozoon sh ...19704991958
carbon dioxide fixation by cells of streptococcus faecalis var. liquefaciens.fixation of nah(14)co(3) by a heavy cell suspension of streptococcus faecalis var. liquefaciens was studied. several nutrients, pyridoxal, riboflavine, adenine, uracil, and o(2) stimulated (14)co(2) incorporation into cells only under conditions that were adequate for synthesis of cell macromolecules. biotin increased co(2) incorporation in the absence of extensive synthesis of macromolecules, whereas o(2) inhibited incorporation under these conditions. when (14)co(2) fixation was occurring duri ...19704990760

induction of enterococcal l-forms by the action of lysozyme.suspensions of enterococci were treated with lysozyme in the presence of osmotic stabilizers. the resulting osmotically fragile bodies prepared from streptococcus faecium strain f24 and s. faecalis strain e1 gave rise to l-forms under optimal osmotic and nutritional conditions for treatment and subsequent growth. the most critical component of the growth medium, to obtain maximum yields, was the nature and concentration of the added salt. the two most effective salts were sodium chloride and amm ...19704990848
