o-succinylbenzoate: coenzyme a ligase, an enzyme involved in menaquinone (vitamin k2) biosynthesis, displays broad specificity.o-succinylbenzoate: coenzyme a ligase, an enzyme involved in menaquinone biosynthesis, was purified from mycobacterium phlei and characterized with respect to isoelectric point, molecular weight, ph optimum, temperature optimum and kinetic data. the enzyme hydrolyses atp to amp. the substrate and cofactor specificity of the enzyme was tested with analogues of o-succinylbenzoic acid, different nucleotides, thiols and divalent cations. the enzyme appears to possess broad specificity for substrates ...19911663748
mechanism of gram variability in select bacteria.gram stains were performed on strains of actinomyces bovis, actinomyces viscosus, arthrobacter globiformis, bacillus brevis, butyrivibrio fibrisolvens, clostridium tetani, clostridium thermosaccharolyticum, corynebacterium parvum, mycobacterium phlei, and propionibacterium acnes, using a modified gram regimen that allowed the staining process to be observed by electron microscopy (j. a. davies, g. k. anderson, t. j. beveridge, and h. c. clark, j. bacteriol. 156:837-845, 1983). furthermore, since ...19901689718
immunization against anthrax with bacillus anthracis protective antigen combined with adjuvants.the protective efficacy of immunization against anthrax with bacillus anthracis protective antigen (pa) combined with different adjuvants was tested in hartley guinea pigs and cba/j and a/j mice. adjuvant components derived from microbial products that were tested included threonyl-muramyl dipeptide (threonyl-mdp); monophosphoryl lipid a (mpl); trehalose dimycolate (tdm); and the delipidated, deproteinized, cell wall skeleton (cws) from either mycobacterium phlei or the bcg strain of mycobacteri ...19921730501
interferon gamma fails to activate human monocyte-derived macrophages to kill or inhibit the replication of a non-pathogenic mycobacterial species.the ability of interferon gamma (gamma) to activate human macrophages to kill mycobacteria was investigated using a mycobacterial species that does not cause disease in man. although interferon activated human macrophage activity against other intracellular parasites, toxoplasma gondii and listeria monocytogenes, it failed to activate human monocyte-derived macrophages to kill not only mycobacterium tuberculosis but also the non-pathogenic species, mycobacterium phlei.19911813779
evaluation of enzyme-linked immunosorbent assay in comparison with complement fixation test for the diagnosis of subclinical paratuberculosis in cattle.an enzyme-linked immunosorbent assay (elisa) was evaluated and compared in parallel with the standard complement fixation test (cft) for the diagnosis of bovine subclinical paratuberculosis. bovine sera preabsorbed with the mixture of mycobacterium phlei and kaolin suspension were assayed for antibody activities to the crude protoplasmic antigen of mycobacterium paratuberculosis in the elisa. elisa antibody titer was expressed as elisa antibody index (eai) value: eai = (at-an)/(ap-an), where at, ...19911834198
nonsporulating bacterial species contain dna sequences homologous to the bacillus spore-specific c-protein gene.genes for small, acid-soluble spore proteins (sasps) are ubiquitous among the spore-forming bacteria and are expressed only during sporulation. although they perform the function of amino acid storage in spores, the members of the sasp-c multigene family probably serve additional functions, so that similar sequences might be present in non-spore-formers. using the sasp-c gene (ssp-c) as a hybridization probe, restriction digests of whole genomic dna from seven nonsporulating bacterial species we ...19911848527
tumor necrosis factor alpha mediates lethal activity of killed gram-negative and gram-positive bacteria in d-galactosamine-treated mice.treatment with d-galactosamine increases sensitivity of lipopolysaccharide (lps)-responder mice to the lethal effects of lps, while nonresponder mice remain resistant (m.a. freudenberg, d. keppler, and c. galanos, infect. immun. 51:891-895, 1986). in the present study it is shown that, in contrast to lps, killed gram-negative bacteria (salmonella abortus equi and s. typhimurium) were highly toxic for d-galactosamine-treated lps-responder (c57bl/10 scsn and c3h/hen) and -nonresponder (c57bl/10 sc ...19912037372
the sensitivity and specificity of a modified elisa for the diagnosis of johne's disease from a field trial in cattle.an enzyme-linked immunosorbent assay (elisa) for the detection of antibodies against mycobacterium paratuberculosis in cattle was evaluated in three herds known to have johne's disease. prior to testing, the plasma was absorbed with dried mycobacterium phlei in order to remove cross-reacting antibody specificities. the sensitivity and specificity of the elisa were calculated after repeatedly testing 327 cattle in the infected herds. of these, 53 animals had one or more positive faecal cultures o ...19902281604
selective enzyme staining procedures for characterization of mycobacterial immunoprecipitates.selective staining procedures for four different enzymes (malate dehydrogenase, glutamic oxaloacetic transaminase, leucine aminopeptidase and glucose phosphate isomerase) in combination with two-dimensional immunoelectrophoresis were successfully applied to the analysis of antigen preparations from mycobacteria. thus, a precipitate corresponding to malate dehydrogenase could e.g. be demonstrated in multi-linear precipitation patterns of mycobacterium avium, mycobacterium bovis bcg, mycobacterium ...19862417958
step-wise isolation of rna and dna from mycobacteria.mycobacterium phlei and m. smegmatis were lysed at -15 degrees c in the presence of guanidinium salts and poly(a)+-rna. nonpolyadenylated rna (mainly rrna) and dna were isolated in successive steps from the same lysate. dna isolated by this procedure was sufficient to yield distinct bands on treatment with restriction endonucleases as shown by hybridization to 125i-labeled rrna. the successive isolation of poly(a)+-rna, nonpolyadenylated rna, and high molecular weight dna from the same lysate by ...19862427627

physical and chemical characterization of glutamine synthetase purified from mycobacterium phlei.glutamine synthetase (l-glutamate: ammonia ligase [adp forming]) [ec 6.3.1.2] has been purified from a gram-positive, acid-fast bacterium, mycobacterium phlei, by simple procedures with 57% recovery. the enzyme resembled that from mycobacterium smegmatis in the subunit size (56,000), molecular weight (670,000), amino acid composition, the amino acid sequence of the nh2-terminal, and the secondary structure. the enzyme activity was regulated by adenylylation of each subunit in the dodecameric mol ...19892569461
trehalose dimycolate enhances resistance to infection in neutropenic animals.bacterial infections are lethal complications of neutropenia, and antibiotics alone are inadequate therapy for these infections. irradiated mice become severely neutropenic and remain susceptible to infection for 2 to 3 weeks, depending on the dose and quality of radiation. some bacterial cell wall derivatives stimulate nonspecific host defense mechanisms against a variety of microbes which might cause postirradiation infection. in this study we determined if the cell wall glycolipid trehalose d ...19892663726
mycolic acid metabolic filiation and location in mycobacterium aurum and mycobacterium phlei.synchronous cultures of mycobacterium aurum were used to prove a close relationship between cellular division and active synthesis of mycolic acids (characteristic long-chain 3-hydroxyacids, branched at position 2), confirming previous proposals. mycolic acid biosynthesis was studied in two species (mycobacterium phlei and m. aurum) each producing three types of mycolic acids: di-unsatured mycolates, oxomycolates and wax-ester mycolates (ester of dicarboxymycolic acid and 2-icosanol or 2-octadec ...19892714297
septic arthritis due to mycobacterium phlei presenting as infantile reiter's syndrome.we describe a 7-year-old peruvian boy who presented with a 2 week history of conjunctivitis, urethritis and arthritis, in whom mycobacterium phlei was the only organism repeatedly isolated from synovial fluid and tissue and who responded to conventional antituberculous therapy. to our knowledge this is the first documented case of human disease caused by this microorganism.19892810265
regulation of glutamine synthetase activity by phosphorylation instead of by adenylylation.o-phosphotyrosyl glutamine synthetase (p-gs) was isolated from highly adenylated glutamine synthetase (amp-gs) purified from mycobacterium phlei, by treatment with micrococcal nuclease. the physical characteristics of p-gs were quite similar to those of amp-gs except for the uv-absorption spectrum. in either mg2+- or mn2+-dependent biosynthetic reactions, the kinetic properties, such as optimum ph, vmax, and apparent km for each of three substrates of p-gs, were found to be in good agreement wit ...19882902854
aspects of mycobacterial response to beryllate ions in vitro.comparative growth measurements of the mycobacterial species mycobacterium phlei and mycobacterium tuberculosis were carried out with liquid cultures supplemented with oxalatoberyllate ions in the concentration range 0-120 microm be. for both species, the effect of beryllium on specific growth parameters can be represented by a be concentration-dependent, exponential expression. evidence for beryllium binding to cellular phospholipids (approximately 15% of be uptake) is provided by 31p nmr spect ...19862946115
4-(2'-carboxyphenyl)-4-oxobutyryl coenzyme a ester, an intermediate in vitamin k2 (menaquinone) biosynthesis.enzyme preparations from mycobacterium phlei, escherichia coli and galium mollugo cell suspension cultures were incubated in the presence of 4-(2'-carboxyphenyl)-4-oxobutyrate (i.e. o-succinylbenzoic acid, osb, 1), atp, coenzyme a and mg2+. the main product isolated from the incubation mixture was 4-(2'-carboxyphenyl)-4-oxobutyryl coenzyme a ester (2) as determined by comparison with synthetic coenzyme a esters. synthetic and enzymically formed 4-(2'-carboxyphenyl)-4-oxobutyryl coenzyme a ester ...19872966501
evidence for genetic divergence in ribosomal rna genes in mycobacteria.dna was isolated from mycobacterium phlei and from m. smegmatis. each dna sample was restricted with endonucleases, the fragments were separated by agarose gel electrophoresis and transferred to nitrocellulose film. fragments of dna containing rrna sequences were identified by means of 125i-labelled rrna of m. phlei or of m. smegmatis. the distributions of restriction endonuclease sites within the rrna gene(s) and flanking sequences were found to be characteristic for each of the two species. hy ...19863002853
phenotypic changes in mycobacteria grown in oxygen-limited conditions.laboratory strains of mycobacterium phlei, m. smegmatis, m. fortuitum, m. gordonae, m. kansasi, m. bovis, m. tuberculosis and m. intracellulare were adapted to grow in an anaerobic environment. concomitant with the transition to anaerobic growth was loss of acid-fastness, loss or modification of colonial pigmentation, and loss of ability to grow on a malachite green-containing medium. the mycobacteria grown anaerobically produced acid from a greater range of carbohydrates than aerobically grown ...19863084791
differentiation of mycobacterium thermoresistibile from mycobacterium phlei and other rapidly growing mycobacteria.mycobacterium thermoresistibile is the only chromogenic rapidly growing mycobacterial species reported to cause infections in humans and animals. dna-dna hybridization (s1 nuclease method) showed that m. thermoresistibile formed a dna relatedness group which was only 24 to 30% related to m. phlei. alkaline phosphatase and beta-galactosidase differentiated m. thermoresistibile from m. phlei. among the rapidly growing mycobacteria, the mycolic acid pattern of m. thermoresistibile was unique (alpha ...19863122636
influence of oxygen tension on the respiratory activity of mycobacterium phlei.growth of mycobacterium phlei under low oxygen tension resulted in specific activities two to twenty times lower for formate dehydrogenase, malate dehydrogenase, beta-hydroxybutyrate dehydrogenase, lactate oxidase and nadh dehydrogenase than when cultures were grown under high aeration. an increase in fumarate reductase and succinate dehydrogenase occurred with m. phlei grown under low oxygen tension. malate: vitamin k dehydrogenase and glucose-6-phosphate dehydrogenase activity were not signifi ...19883183614
