bacteriolytic spectrum of the enzyme produced by acanthamoeba castellanii.		1969	4905249
scanning electron and phase-contrast microscopy of bacterial spores.	the three-dimensional immages of free and intrasporangial spores produced by scanning electron microscopy show surface structures not visible by phase-contrast microscopy. although fine surface detail is not elucidated by scanning electron microscopy, this technique does afford a definitive picture of the general shape of spores. spores of bacillus popilliae, b. lentimorbus, b. thuringiensis, b. alvei, b. cereus, and sarcina ureae have varying patterns of surface ridge formation, whereas spores ...	1969	4907010

procedures for the assay of carbenicillin in body fluids.	the assay of carbenicillin in clinical specimens is complicated by the fact that carbenicillin also contains a small amount of benzylpenicillin, thereby precluding the use of conventional penicillin assay organisms. this report gives details of a microbiological assay method involving the use of a strain of pseudomonas aeruginosa which is very sensitive to carbenicillin but insensitive to benzylpenicillin. the outline of a microassay method with this organism is presented, and a method for the a ...	1970	4985430
comparative allostery of 3-deoxy-d-arabino-heptulosonate-7-phosphate synthetase as a molecular basis for classification.	the allosteric pattern of control for 3-deoxy-d-arabino-heptulosonate 7-phosphate (dahp) synthetase has previously been shown to be strongly conserved among the member species of a given genus in bacteria. the implications of this finding as a procedural tool of bacterial phylogeny were pursued by a study of two organisms, sporosarcina ureae and aeromonas formicans, the taxonomic positions of which have been historically controversial. s. ureae has characteristics of both bacillaceae and microco ...	1970	4985590

microbioassay of antimicrobial agents.	a previously described agar-diffusion technique for microbioassay of antimicrobial agents has been modified to increase sensitivity of the technique and to extend the range of antimicrobial agents to which it is applicable. this microtechnique requires only 0.02 ml of an unknown test sample for assay, and is capable of measuring minute concentrations of antibiotics in buffer, serum, and urine. in some cases, up to a 20-fold increase in sensitivity is gained relative to other published standardiz ...	1970	4986725

amino acid sequence of the murein of planococcus and other micrococcaceae.	the amino acid composition and amino acid sequence of the murein (peptidoglycan) of 10 strains of planococci were studied. it is shown that the peptide subunit consists of muramyl-l-alanyl-gamma-d-glutamyl-l-lysyl-d -alanine. the cross-linking of two adjacent peptide subunits is mediated by d-glutamic acid which is bound to the epsilon-amino group of lysine by its gamma-carboxyl group and to the carboxyl group of d-alanine of an adjacent peptide subunit by its amino group. about 20 to 25% of the ...	1970	4247024

endo-n-acetyl-glucosaminidase from clostridium perfringens, lytic for cell wall murein of gram-negative bacteria.	an endo-n-acetyl-glucosaminidase which degrades the murein (peptidoglycan) sacculi of the cell walls of escherichia coli and spirillum serpens, but not those of micrococcus lysodeikticus and sarcina lutea, is present as a contaminant in a "phospholipase c" from clostridium perfringens. the specificity of enzyme action was elucidated by reduction of liberated glycosidic groups with nabh(4) and identification of glucosaminol as the reduction product. this finding contradicts previous reports assoc ...	1970	4315891

the effect of high vacuum on oxidative reactions in bacteria and the activity of certain enzymes.	among the physical factors which might influence micro-organisms one of the most potentially interesting is high vacuum. the effect of high vacuum is less studied as compared with other physical factors. it is impossible to achieve, under laboratory conditions, a vacuum of the order 10(-16) mm hg which is probably characteristic of space. earlier, the effect of high vacuum was studied on different bacteria, yeasts, molds and algae. it appeared that spores and fungal conidia were not killed by hi ...	1970	12664921
methods for the determination of deoxyribonucleic acid homologies in streptomyces.	variations of the membrane filter technique for deoxyribonucleic acid (dna) hybridizations were studied with respect to streptomyces species. at the temperatures required for specific hybridization of dna with the high melting temperature (t(m)) characteristic of streptomyces, large amounts (up to 97%) of filter-bound dna became eluted, in all reaction mixtures studied, within 21 hr. in most solutions this leaching was increased by the presence of sheared denatured dna. incubation of dna-loaded ...	1970	16559080

use of antibody to membrane adenosine triphosphatase in the study of bacterial relatioships.	an antiserum to ca(2+)-activated adenosine triphosphatase from membranes of micrococcus lysodeikticus cross-reacted in agar gels with membrane adenosine triphosphatases from other pigmented micrococci and related species. species of micrococcus and sarcina showed different levels of inhibition of adenosine triphosphatase activities in heterologous reactions with antiserum. inter- and intraspecific relationships based on the inhibition reaction were compared with an independent parameter, namely ...	1971	4323299
specific assay of aminoglycosidic- or polymyxin-type antibiotics present in human sera in combination with cephalosporins.	monitoring of serum concentrations of aminoglycosidic or polymyxin antibiotics when administered concurrently with cephalosporins or penicillins requires a special assay technique. selective enzymatic degradation of the beta-lactam antibiotic from the serum specimen allows subsequent assay of the antibiotic being monitored. this report gives details of a simple procedure for laboratory production of a crude enzyme capable of degrading cephalosporins or penicillins. an assay procedure for quantit ...	1971	4327609
confirmation of the identification of the major c-29 hydrocarbons of sarcina lutea.	although there is agreement on the fact that sarcina lutea strain fd-533 has branched c-29 monoalkenes as major hydrocarbon components, there is disagreement in the literature as to the nature of the branching. this has been resolved by analyses of the fatty acids produced by permanganate-periodate treatment of each of the resolvable hydrocarbon fractions making up the c-29 complex. the three major components are identified as doubly branched, delta(13) species with two iso terminations, one iso ...	1971	4330736

cephaloglycin and its biologically active metabolite desacetylcephaloglycin.	chromatographic studies and microbiological assays show that, after oral administration, cephaloglycin is partially converted in man to a biologically active metabolite desacetylcephaloglycin. the antibacterial activity of this metabolite compared to that of cephaloglycin is equivalent against gram-positive organisms but is lower against gram-negative bacilli. successful therapy of urinary tract infections with cephaloglycin must be mainly attributed to the antibacterial activity of this metabol ...	1971	4994901

inhibition of the plaquing efficiency of t4r+ bacteriophage by subtilisin.	the mechanism by which the replicative cycle of t4r(+) phage is inhibited by certain nonhost bacterial systems was investigated. some bacillaceae, especially bacillus subtilis, decreased the plaquing efficiency of this virus more than 95% within 24 hr of exposure. sarcina lutea and micrococcus sp. both failed to cause any significant change in the infectivity of t4r(+) phage. preliminary investigations into the nature of the inhibitory substance(s) suggested that an extracellularly elicited prot ...	1971	4995848
