| influence of the ph-value on the growth of staphylococcus epidermidis, staphylococcus aureus and propionibacterium acnes in continuous culture. | a cutaneous isolate of staphylococcus epidermidis, staphylococcus aureus and propionibacterium acnes was grown in continuous culture at varying ph-values ranging from 5.0 to 8.5. in terms of the specific growth rate as well as the bacterial density during the plateau phase there were remarkable differences. in particular, propionibacterium acnes grew much better in the ph 6.0 to 7.0 range than in a more acidic or alkaline milieu. staphylococcus epidermidis resembled staphylococcus aureus showing ... | 1992 | 1503605 |
| murine kupffer cells and hepatic natural killer cells regulate tumor growth in a quantitative model of colorectal liver metastases. | this investigation aimed to develop a biologically relevant murine model of colorectal liver metastases and determine if kupffer cells (kc) and hepatic natural killer cells (hnkc) regulate tumor growth. the model involves the injection of murine colon adenocarcinoma 26 (mca 26) tumor cells into the portal vein of female-specific pathogen-free balb/c mice. metastases developed in all animals, and the growth was limited entirely to the liver. to determine if kc and hnkc control the development of ... | 1992 | 1505122 |
| bacteriology of ophthalmic infections with special reference to anaerobes. | a total of 138 eye specimens were processed for aerobic and anaerobic cultures. clinical data were obtained from 50 patients with unilateral ophthalmic infection. cultures from the uninfected eye of 38 of these 50 patients were also processed for comparison. in addition, 50 cultures were obtained from one or both eyes of 30 healthy controls who had no eye infection. anaerobes and aerobes were isolated from infected eyes of 6 (12%) and 37 (74%) patients respectively. no growth was observed in inf ... | 1992 | 1506066 |
| development of cutaneous microflora in premature neonates. | coagulase-negative staphylococci (c-ns) are a frequent cause of bacteraemia in premature neonates. it is likely that the strains of c-ns causing bacterial sepsis in premature neonates have their origin on the patient's skin surface. we have studied the quantitative development of the skin microflora at eight sites on premature neonates. a swab wash method was used to sample and enumerate the cutaneous microflora of premature neonates admitted to an intensive care unit with respiratory distress s ... | 1992 | 1519978 |
| antibacterial activity of crinitol and its potentiation. | an acyclic diterpene alcohol, crinitol [1], was identified in a marine brown alga, sargassum tortile, as the principal antibacterial agent against gram-positive bacteria, among which propionibacterium acnes was most sensitive and, staphylococcus aureus was least. to enhance its activity, crinitol was combined with several antioxidants, which presumably retard oxidative destruction of this molecule which possesses two easily oxidizable allylic alcohol groups. two synthetic antioxidants, bha (buty ... | 1992 | 1522419 |
| the importance of methionine residues for the catalysis of the biotin enzyme, transcarboxylase. analysis by site-directed mutagenesis. | almost all biotin enzymes contain the conserved tetrapeptide ala-met-bct-met (bct, n epsilon-biotinyl-l-lysine). in the 1.3 s biotinyl subunit of transcarboxylase (tc), this sequence is present between positions 87 and 90. the conserved nature of these amino acids implies a critical role in the function of biotin enzymes. in order to examine the role of these conserved amino acids, point mutations in the gene encoding the 1.3 s subunit have been made by site-directed mutagenesis to generate a87g ... | 1992 | 1526981 |

| jenseniin g, a heat-stable bacteriocin produced by propionibacterium jensenii p126. | the genus propionibacterium includes cutaneous species typically found on human skin and the dairy or classical species (propionibacterium freudenreichii, p. jensenii, p. thoenii, and p. acidipropionici) used industrially for the production of swiss cheese and propionic acid. grinstead (1989, m.s. thesis, iowa state university, ames) has previously observed that some dairy propionibacteria inhibit other species in the classical grouping. we further investigated the inhibitor(s) produced by p. je ... | 1992 | 1539976 |
| antimicrobial activity of sphingosines. | the antimicrobial activity of stratum corneum lipids was examined by screening in vitro various representative phospholipids and sphingolipids. of mixed galacto-cerebrosides; phosphatidic acid; phosphatidic acid-monomethylester-dioleoyl; phosphatidylethanolamine; phosphatidylethanolamine-beta-oleoyl-gamma-palmitoyl; phosphatidylcholine; d-sphingosine; d,l-sphinganine; 4-d-hydroxysphinganine; oleoyl-sphingosine; n,n-dimethylsphingosine; and stearylamine, only the sphingosines and, to a lesser ext ... | 1992 | 1545135 |
| bacteriologic and endotoxin analysis of salvaged blood used in autologous transfusions during cardiac operations. | autologous blood transfusion is a common method of reducing the need for heterologous blood transfusion during cardiac operations. recently we investigated an outbreak of severe, nonsurgical postoperative bleeding among patients undergoing heart operations and receiving intraoperative transfusion of blood from a cell conservation device (cell saver system, haemonetics corp., braintree, mass.). as a result of this investigation, we conducted a prospective study to determine if bacterial or endoto ... | 1992 | 1545559 |
| antimicrobial susceptibility of anaerobic bacteria in auckland 1987-90. | the antimicrobial susceptibility of 292 clinical isolates of anaerobic bacteria was determined by a standard agar dilution method. metronidazole was the most active agent with only one bacteroides fragilis, two anaerobic cocci, and propionibacterium acnes being resistant. for b fragilis itself and other members of the b fragilis group: 35/35 (100%) and 43/44 (98%) respectively, were susceptible to amoxycillin-clavulanic acid; 47/47 (100%) and 55/56 (98%) respectively, were susceptible to cefoxit ... | 1992 | 1549266 |
| propionibacterium acnes-enhanced lens-induced granulomatous uveitis in the rat. | propionibacterium acnes (corynebacterium parvum) is being implicated more frequently as a cause of intraocular inflammation following cataract surgery. in addition to its role as an infectious agent, p. acnes also may possess adjuvant-like or adjuvant-enhancing properties. the presence of this organism in an eye with residual lens material after extracapsular cataract surgery could augment inflammation resulting from a phacoantigenic (phacoanaphylactic) response. we have modified an established ... | 1992 | 1559776 |
| separation of soluble amoebicidal and tumoricidal activity of activated macrophages. | macrophage-conditioned medium (m phi cm) prepared from mouse peritoneal macrophages activated in vivo with bacillus calmette-guérin (bcg) or propionibacterium acnes and triggered with lipopolysaccharide in vitro contained tumoricidal and amoebicidal activity. the murine fibroblast cell line l929 was used as the indicator of tumoricidal activity and naegleria fowleri amoeba was used to detect amoebicidal activity in m phi cm. the protease inhibitor, soybean trypsin inhibitor, decreased tumoricida ... | 1992 | 1560419 |
| propionibacterium acnes prosthetic valve endocarditis: a case of severe aortic insufficiency. | propionibacterium acnes rarely causes systemic disease. few cases of p. acnes endocarditis have been reported. this report describes a 63-year-old man who presented with severe congestive heart failure. he had prosthetic valve endocarditis which resulted in severe acute aortic insufficiency. during surgery he was found to have complete disruption of the aorta and left ventricle with a false aneurysm encompassing the circumference of the aortic annulus. cultures of the valve grew p. acnes. thus, ... | 1992 | 1563134 |
| gamma interferon mediates propionibacterium acnes-induced hypersensitivity to lipopolysaccharide in mice. | pretreatment of lipopolysaccharide (lps)-responder c57bl/10scsn mice with killed propionibacterium acnes enhanced tumor necrosis factor alpha (tnf-alpha) production and lethality in response to a subsequent challenge with lps. sensitization to lps increased with time of pretreatment and reached its maximum after 7 days. sensitization was paralleled by gamma interferon (ifn-gamma) production that was detectable from day 3 onward. in contrast, a similar p. acnes pretreatment of lps-nonresponder c5 ... | 1992 | 1563791 |
| [release of interleukin-6 by alveolar macrophages in patients with sarcoidosis]. | the supernatants from cultures of alveolar macrophages from 12 patients with sarcoidosis and 7 control subjects were assayed for interleukin-6 (il-6) using an elisa system. il-6 was detectable without a stimulant in supernatants from all subjects with sarcoidosis and controls. however, the supernatants from 4 of 12 untreated patients with sarcoidosis contained significantly greater amounts of il-6. when macrophages were stimulated by propionibacterium acnes (p. acnes), the mean level of il-6 in ... | 1992 | 1569718 |
| risk of bacteremia induced by transesophageal echocardiography: analysis of 100 consecutive procedures. | the incidence of bacteremia induced by transesophageal echocardiography (tee) and, consequently, the need for an antibiotic prophylaxis before tee is still controversial. therefore, we studied the incidence of bacteremia associated with tee prospectively in 100 consecutive patients without clinical or laboratory signs of bacterial infection. blood samples were drawn immediately before and at 0, 5, and 15 minutes after tee. in addition, swabs were taken from the pharyngeal region before tee and f ... | 1992 | 1571172 |
| biofilms on indwelling vascular catheters. | some bacteria have a natural tendency to adhere to available surfaces and to form biofilms. biofilms have been demonstrated on right heart flow-directed catheters, endocardial pacemaker leads, urinary catheters, and other medical devices. in this study, we examined arterial and central venous catheters that had been in place in icu patients between 1 and 14 days for the presence of bacterial biofilms by scanning electron microscopy, transmission electron microscopy, and a special scraping/sonica ... | 1992 | 1572192 |

| induction of murine lymphokine-activated killer-like cells by corynebacterium parvum (c. parvum) in vitro: lysis of tumor cells and macrophages by c. parvum-induced killer cells. | in vitro culture of murine spleen cells with corynebacterium parvum (c. parvum) was found to induce lymphokine-activated killer (lak)-like cells capable of killing both natural killer (nk)-sensitive and nk-resistant tumor cells as well as syngeneic macrophages (m phi). the induction of lak-like activity by c. parvum was significantly inhibited by anti-interleukin-2 (il-2) or anti-interferon (ifn) alpha, beta antibody (ab), and it was further inhibited by the combination of two abs, suggesting th ... | 1992 | 1580562 |
| influence of corynebacterium parvum-per on disease progression in the nzb/w model of systemic lupus erythematosus. | murine models of systemic lupus erythematosus (sle) exhibit some, but not all, of the characteristics of human disease. disease progression in the animal models is regulated by autoantibodies, genetics and inflammatory processes. in the present study, the influence of the pyridine extract residue of corynebacterium parvum type i (cp-per) on disease progression in the nzb/w model of sle was investigated. cp-per is known to activate the reticuloendothelial (re) system of mice and can alter a numbe ... | 1992 | 1582732 |
| generation of cytotoxic immune responses against a rat glioma by in vivo priming and secondary in vitro stimulation with tumor cells. | cytotoxic t lymphocyte (ctl) responses to most antigens are generated by in vivo priming and secondary stimulation with antigen in vitro. the present studies were designed to determine whether that strategy could be used to stimulate development of ctl against brain tumors. rats were primed with one of two tumors, rt2, an astrocytoma, or 9l, a gliosarcoma, and corynebacterium parvum. spleen cells from primed rats were stimulated with tumor cells and interleukin-2 in vitro to generate ctl. ctl ge ... | 1992 | 1584347 |
| propionibacterium acnes endophthalmitis after intracapsular cataract extraction. | the authors report a case of propionibacterium acnes endophthalmitis after intracapsular cataract extraction with implantation of an anterior chamber intraocular lens. the patient's chronic inflammation persisted for 5 years after cataract surgery despite treatment with pars plana vitrectomy, intraocular lens removal, topical and oral steroids, and topical fortified antibiotics. fluctuations in the inflammation were paralleled by changes in the size and appearance of a white plaque on the poster ... | 1992 | 1584564 |
| corynebacterium parvum can reverse the depression of macrophage hydrogen peroxide production caused by erythrocyte phagocytosis. | our previous studies have shown that the phagocytosis of igg-coated erythrocytes (eigg) in vivo increases the mortality rate with bacterial infection, and eigg phagocytosis in vitro depresses phorbol myristate acetate (pma)-triggered h2o2 production. the present study was undertaken to determine if the depression of h2o2 production caused by eigg phagocytosis could be reversed by exposing macrophages to priming agents. macrophages exposed to 100 micrograms/ml of c. parvum, it's pyridine-soluble ... | 1992 | 1587558 |
| high serum il-6 level reflects susceptible status of the host to endotoxin and il-1/tumor necrosis factor. | patients with high level of serum endotoxin did not necessarily develop into lethal shock, whereas some patients died of septic shock even when their serum endotoxin levels were low. these results indicate that limiting factor which determines the host to be endotoxin shock principally depends on the host susceptibility to endotoxin instead of serum endotoxin level. to understand this susceptible status of the host to endotoxin, we used propionibacterium acnes primed mouse endotoxin shock model. ... | 1992 | 1588048 |
| susceptibilities of anaerobic bacteria isolated from animals with ovine foot rot to 28 antimicrobial agents. | the agar dilution method was used to determine the inhibitory activities of 28 antimicrobial agents against 35 strains of the genus peptostreptococcus, 4 strains of the species peptococcus niger, 20 strains of the species megasphaera elsdenii, 7 strains from the species acidaminococcus fermentans, 8 strains of the genus clostridium, 11 strains of the genus eubacterium, and 1 strain of the species propionibacterium acidipropionici, all of which were isolated from 125 clinical cases of ovine foot ... | 1992 | 1590689 |
| [transformation of [5'-3h]riboflavin into 5,6-dimethylbenzimidazole]. | the 5,6-dimethylbenzimidazole unit of vitamin b12 is formed from riboflavin via fmn in aerobic and some aerotolerant bacteria. thereby c-1' of the ribityl side chain gets c-2 of 5,6-dimethylbenzimidazole. experiments with homogenates of propionibacterium shermanii on the fate of c-atoms 2' to 5' of the ribityl side chain of riboflavin in this transformation are reported. it was found that [5'-3h]riboflavin leads to radioactive sugar phosphates. these were isolated, dephosphorylated, and separate ... | 1992 | 1590885 |
| [splenic abscess: therapeutic options]. | pyogenic splenic abscess is a rare condition that tends to occur in patients with underlying often infectious diseases. the sensitivity of ultrasonography and computerized tomography has improve early diagnosis and follow-up. in our hands, splenectomy remains the therapy of choice, but we report the resolution of two uncomplicated splenic abscesses with antibiotics alone. | 1992 | 1592631 |
| susceptibility of anaerobic bacteria to tosufloxacin. | the in vitro activity of tosufloxacin against anaerobic cocci, propionibacterium acnes, clostridium perfringens, clostridium difficile, bacteroides fragilis, bacteroides spp. and fusobacteria was determined by the agar dilution method. this activity was compared with that of ciprofloxacin, piperacillin, cefoxitin, imipenem, clindamycin, metronidazole and chloramphenicol. tosufloxacin, imipenem, clindamycin, metronidazole and chloramphenicol were the most active agents tested. tosufloxacin has an ... | 1992 | 1597207 |
| validity of delayed-type hypersensitivity and graft-versus-host reaction in testing of immunomodulators. | assessment of cell-mediated immunity (cmi) is an integral part of preclinical studies of pharmaceuticals and xenobiotics. even if several tests to determine cmi are available, their interpretation is fraught with uncertainty whether identical results can be expected for each of these particular tests after the challenge with different immunomodulatory substances. this dilemma has been addressed by investigating the changes in two basic tests of cmi in vivo, i.e. delayed-type hypersensitivity (dt ... | 1992 | 1597252 |

| immunologically mediated fatigue: a murine model. | chronic fatigue syndrome (cfs) is an idiopathic disorder in which the chief symptoms is profound fatigue. to explore the relationship between immune stimulation and fatigue, we developed a murine model for quantifying fatigue: reduction in voluntary running and delayed initiation of grooming after swimming. inoculation of female balb/c mice with corynebacterium parvum antigen or the relatively avirulent me49 strain of toxoplasma gondii induced fatigue: baseline running reduced to less than 50 an ... | 1992 | 1643746 |
| effects of corticosterone and microgravity on inflammatory cell production of superoxide. | in this investigation we studied the effects of corticosterone and microgravity on propionibacterium acnes-induced inflammatory cells ability to produce superoxide (o2-). we found in vitro and in vivo exposure of murine peritoneal inflammatory cells to corticosterone did not inhibit the o2- response. we also found that in microgravity p. acnes-induced inflammatory cells were capable of producing four times as much o2- as at 1g. therefore, neither corticosterone nor microgravity experienced durin ... | 1991 | 1647434 |
| comparative studies on a superoxide dismutase exhibiting enzymatic activity with iron and manganese as active cofactor. | the sod of propionibacterium freudenreichii, ssp. shermanii belongs to a new group of sod's capable of retaining activity with either fe or mn as active metal cofactor. both enzymes exhibit identical secondary structure and immunological determinants. hydrogen peroxide irreversibly inhibits both enzymes. the protein moiety of the fe- and mn-sod could be digested with trypsin to a single active fragment. | 1991 | 1649091 |
| activity of mersacidin, a novel peptide, compared with that of vancomycin, teicoplanin, and daptomycin. | mersacidin, a new peptide antibiotic, was four- to eightfold less active (mic for 90% of isolates, 8 micrograms/ml) than vancomycin, teicoplanin, or daptomycin against staphylococcus aureus. coagulase-negative staphylococci were inhibited by 8 micrograms/ml, and the mics of mersacidin for hemolytic streptococci and streptococcus pneumoniae were 4 to 8 micrograms/ml. the mersacidin mics for anaerobic organisms were as follows: clostridium perfringens, 4 micrograms/ml; propionibacterium acnes, 8 m ... | 1991 | 1649577 |
| near-uv-induced radicals in propionibacterium acnes, studied by electron spin resonance spectrometry at 77 k. | suspensions of propionibacterium acnes were uv irradiated and the induced radicals were measured at 77 k by electron spin resonance (esr) spectrometry. two types of radical were formed during irradiation and stabilized in the frozen suspensions. the relative yield of each radical was studied as a function of irradiation wavelength. the first radical, which was a singlet with a peak-to-peak width of 20 g, was insensitive to the deoxygenation of the samples and to the exchange of solvent water by ... | 1991 | 1650821 |
| cloning, sequencing, and expression of pyrophosphate-dependent phosphofructokinase from propionibacterium freudenreichii. | pyrophosphate-dependent 6-phosphofructo-1-kinase (ppi-pfk) from propionibacterium freudenreichii is a non-allosteric enzyme with properties dissimilar to those of other described phosphofructokinases. the enzyme was cloned into pbluescript, sequenced, and expressed in escherichia coli at levels 15 times higher than those observed in propionibacterium. the gene consists of 1215 bases which code for a protein of 404 amino acids and a mass of 43,243 daltons. high g + c in the codon usage (66%) of t ... | 1991 | 1653240 |
| changes in polyphosphate composition and localization in propionibacterium acnes after near-ultraviolet irradiation. | electron microscopy showed that electron-dense granules accumulated in propionibacterium acnes in larger amounts when the bacteria were grown on a phosphate-rich medium. x-ray microanalysis demonstrated that the granules contained mostly phosphorus and potassium, indicating that the cells contained polyphosphate granules. when cells were grown on a complex bacto-agar medium, the amount and the size of the polyphosphate granules were reduced. polyphosphate was also detected with 31p nuclear magne ... | 1991 | 1655185 |
| the appearance of t cells bearing self-reactive t cell receptor in the livers of mice injected with bacteria. | we demonstrated in the present study that with bacterial stimulation, an increased number of alpha/beta t cells proliferated in the liver of mice and that even t cells bearing self-reactive t cell receptor (tcr) (or forbidden t cell clones), as estimated by anti-v beta monoclonal antibodies in conjunction with immunofluorescence tests, appeared in the liver and, to some extent, in the periphery. the majority (greater than 80%) of forbidden clones induced had double-negative cd4-8-phenotype. in a ... | 1991 | 1677392 |
