evaluation of thallium acetate-citrate medium for isolation of enterococci.thallous acetate-citrate (tac) agar, a selective medium for isolating enterococci from frozen foods, was evaluated. two types of bacteria, micrococci and group n streptococci, were responsible for erroneously high enterococcus counts on tac agar. selectivity of the medium was improved by the addition of 0.01% sodium azide.19695370465

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

laboratory studies with a selective enterococcus medium.lancefield group d streptococci are involved with appreciable frequency in a variety of infectious processes. the presumptive recognition of these bacteria on initial culturing of clinical specimens is an objective not attained readily by selective media available in the clinical laboratory. selective enterococcus agar was evaluated with emphasis on its ability to sequester enterococci from specimens with many microbial components. in addition, the sensitivity of this new agar was compared with ...19705485723

studies on the antibacterial and antifungal properties of 1, 4-naphthoquinones.1. new halogenated 1,4-naphthoquinones were synthesized and together with other known 1,4-naphthoquinones, were screened for antibacterial activity by a turbidimetric method, and for antifungal activity by the diffusion method on agar plates.2. the half-wave potentials and the influence on the oxidative phosphorylation of some of these compounds were determined.3. 2-chloro-3,2'-chloro-ethyl-1,4-naphthoquinone (half-wave potential=-187 mv) was the most active compound, completely inhibiting cell ...19704992959

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

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

effect of storage of mueller-hinton agar plates on zone sizes for antimicrobial testing.the length of time mueller-hinton agar plates can be stored at 4 c without affecting the size of zones of inhibition in susceptibility testing by the bauer-kirby method was studied. it was found that these plates can be stored for 3 weeks at 4 c without an appreciable affect on zone sizes. storage of plates in sealed plastic bags did not alter the results significantly. the findings indicate that commercially prepared mueller-hinton agar plates, which may be several days old when received at the ...19704991956
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

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

in-vitro comparison of erythromycin, lincomycin, and clindamycin.the in-vitro antibacterial activities of erythromycin, lincomycin, and clindamycin, a new derivative of lincomycin, were compared. clindamycin was always more active than lincomycin, and was either as active as erythromycin or more so against betahaemolytic streptococci, streptococcus viridans, str. pneumoniae, and erythromycin-sensitive staphylococcus aureus. it was also fully active against most erythromycin-resistant strains of staph. aureus. on the other hand, it was somewhat less active tha ...19704988120
relationship between the location of autolysin, cell wall synthesis, and the development of resistance to cellular autolysis in streptococcus faecalis after inhibition of protein synthesis.ten minutes after inhibition of protein synthesis with chloramphenicol (cap) the ability of cells of streptococcus faecalis (atcc 9790) to autolyze decreased to less than 20% of the rate for exponential-phase cells. after threonine exhaustion, the time for a 50% drop in the rate of cellular autolysis was about 20 min. these rapid increases in resistance to cellular autolysis could not be accounted for by: (i) the relatively slow and small overall decrease in susceptibility of isolated cell walls ...19704988243
site of initiation of cellular autolysis in streptococcus faecalis as seen by electron microscopy.low concentrations of glutaraldehyde (0.1% or higher) blocked cellular and wall autolysis. the site of autolytic activity was studied by allowing cell autolysis to proceed for very short periods (0 to 15 min) before addition of glutaraldehyde. electron microscopy of ultrathin sections showed that the primary site of autolytic activity was the leading edge of the nascent cross wall. the base of the cross wall seemed more resistant than the tip. evidence supporting the involvement of autolysin act ...19704988247
