| [emergent pathologies: rhodococcus equi infection in the acquired immunodeficiency syndrome]. | rhodococcus equi is an intracellular facultative, gram-positive, partially acid-fast, cocco-bacillary microorganism of increasing importance as a pathogen in severely immunocompromised hiv-positive patients. rhodococcus equi may cause invasive pulmonary infection, bacteremia and disseminated infection. rhodococcus equi is easily cultured from blood or sputum on standard media, but is frequently regarded as a contaminant. delay in establishing a definite diagnosis may result in a poor outcome in ... | 1994 | 8003385 |
| rapid degradation of the triazinone herbicide metamitron by a rhodococcus sp. isolated from treated soil. | seven bacterial isolates which degraded the herbicide metamitron (3-methyl-4-amino-6-phenyl-1,2,4-triazin-5-one) were obtained from field-enhanced soil by liquid enrichment culture. all isolates appeared to be identical and a representative, 0246b, was identified as a rhodococcus sp. by cell wall and fatty acid analyses. this isolate degraded metamitron as the sole source of carbon within 24 h at 25 degrees c and this is the first report of a bacterium capable of growing with metamitron as the s ... | 1994 | 8002472 |
| stereoselective epoxidation of 2,2-dimethyl-2h-1-benzopyran-6-carbonitrile. | the chiral intermediate (3s,4r)-trans-3,4-dihydro-3,4-dihydroxy-2,2-dimethyl- 2h-1-benzopyran-6-carbonitrile [(+)-trans diol 3] was made by the stereoselective microbial epoxidation of 2,2-dimethyl-2h-1-benzopyran-6-carbonitrile 1. this compound is a potential intermediate for the total synthesis of potassium-channel openers. several microbial cultures were found which catalyzed the transformation of 1 to the corresponding (3s,4s)-epoxide 2 and (+)-trans diol 3. the two best cultures, corynebact ... | 1994 | 8000876 |
| enzymatic asymmetric synthesis of alpha-methyl arylalkylamines and alpha-methyl arylalkylalcohols by arylalkyl acylamidases. | with the novel microbial enzyme, 'arylalkyl acylamidase', optically active alpha-methyl arylalkylamines and alpha-methyl arylalkylalcohols have been obtained through enantioselective hydrolysis of their racemic amides and esters. (s)-enantiomers of 1-methylbenzylamine, 1-methyl-3-phenylpropylamine and 1-methyl-3-phenylpropanol of high optical purity (> 94% e.e.) were synthesized with the cells of nocardia erythropolis iam 1440 or cellulomonas fimi aku 671. (r)-enantiomer of 1-methyl-3-phenylprop ... | 1994 | 8000864 |
| a kinetic study and application of a novel carbonyl reductase isolated from rhodococcus erythropolis. | the newly described carbonyl reductase from rhodococcus erythropolis (recr) accepts a broad range of substrates. based on the kinetic constants of a variety of methyl and ethyl ketones a hypothetical model of the substrate-binding site is proposed. whether a substrate of interest may be reduced by the recr can be predicted from this model together with the kinetic data. a study of initial velocities and product inhibition is presented, which shows that the kinetics of the recr follow a theorell- ... | 1994 | 8000863 |
| permeabilization of mycolic-acid-containing actinomycetes for in situ hybridization with fluorescently labelled oligonucleotide probes. | the application of whole-cell hybridization using labelled oligonucleotide probes in microbial systematics and ecology is limited by difficulties in permeabilizing many gram-positive organisms. in this investigation paraformaldehyde treatment, acid methanolysis and acid hydrolysis were evaluated as a means of permeabilizing mycolic-acid-containing actinomycetes prior to hybridization with a fluorescently labelled oligonucleotide probe designed to bind to a conserved sequence of bacterial 16s rrn ... | 1994 | 8000549 |
| evaluation of a monoclonal antibody-based colony blot test for rapid identification of virulent rhodococcus equi. | we recently generated a monoclonal antibody immunoglobulin g1 (mab 10g5), which can recognize 15- to 17-kda antigens, virulence-associated antigens of rhodococcus equi, and developed a colony blot enzyme-linked immunosorbent assay with mab 10g5 for the rapid identification of virulent r. equi. in this epidemiologic study, we evaluated the results of the colony blot test in the identification of virulent isolates of r. equi from feces of horses and soil and compared them with those from a convent ... | 1994 | 7999891 |
| haemolytic and phospholipase c (plc) activities of rhodococcus equi. | rhodococcus equi, an intracellular organism causing pneumonia and lung abscesses in foals, is generally thought to be non-haemolytic. in the present study, however, 13 of 14 representative isolates were found to be haemolytic when tested on agar media containing washed red blood cells rather than whole blood. red cells of rabbits, dogs, horses and man were more sensitive to lysis than were those of ruminants. two new enzymatic activities of the species were defined: a lecithinase and a phosphati ... | 1994 | 7989259 |
| review of 40 cases of lung abscesses in foals and adult horses. | a retrospective study of 40 horses with primary lung abscesses without pleuropneumonia showed that lung abscesses occurred predominantly in young horses, usually in foals aged < or = 6 months. hyperfibrinogenaemia was present in all but 2 horses, and other common clinical and haematological findings were hyperthermia, tachycardia, polypnoea, and neutrophilic leucocytosis. the most common bacterial species isolated from transtracheal aspirates were streptococcus zooepidemicus (20/34) and rhodococ ... | 1994 | 7988535 |
| rhodococcus equi pneumonia in an hiv-infected patient. | we report a case of a 46-year-old hiv-infected patient suffering rhodococcus equi pneumonia and septicaemia. after the failure of an initial antibiotic treatment, the upper lobe of the right lung was resected due to a cavitating pneumonia. after that the patient stabilized for a period of 7 months by administration of a resistogram-adapted combination of tetracycline, erythromycin and clindamycin. due to the patient's decision, antibiotic treatment was stopped when a cytomegalovirus retinitis wa ... | 1994 | 7987063 |
| brain abscess due to gordona terrae in an immunocompromised child: case report and review of infections caused by g. terrae. | a brain abscess complicated antineoplastic chemotherapy for a primary cerebral rhabdoid tumor in an immunocompromised boy. culture of purulent exudate obtained by surgical puncture of an intracranial hematoma yielded a gram-positive microorganism initially identified as a rhodococcus species by conventional biochemical analysis; however, the isolate was subsequently identified as gordona terrae by ribosomal dna analysis. to our knowledge, this is the third case of human infection caused by g. te ... | 1994 | 7986897 |
| identification of a heroin esterase in rhodococcus sp. strain h1. | a strain of a rhodococcus sp. (termed h1) capable of utilizing heroin as its sole carbon and energy source was isolated by selective enrichment. an inducible heroin esterase was partially purified and shown to catalyze the hydrolysis of both of the acetylester groups of heroin. the enzyme displays optimum activity at ph 8.5 and appears to be a trimer of identical subunits with an m(r) or 39,000 and a native m(r) of 120,000. | 1994 | 7986057 |
| transfer of rhodococcus aichiensis tsukamura 1982 and nocardia amarae lechevalier and lechevalier 1974 to the genus gordona as gordona aichiensis comb. nov. and gordona amarae comb. nov. | we investigated the taxonomic status of rhodococcus aichiensis dsm 43978t (t = type strain) and nocardia amarae dsm 43392t by using both chemotaxonomic and genetic methods. the occurrence of mk-9(h2) as the predominant menaquinone, the presence of relatively long-chain mycolic acids (48 to 62 carbon atoms), and the phylogenetic position as determined by a 16s ribosomal dna sequence analysis provide strong evidence that both r. aichiensis and n. amarae should be transferred to the genus gordona a ... | 1994 | 7981103 |
| [serodiagnosis of caseous lymphadenitis (pseudotuberculosis) in sheep]. | random postmortal isolation of corynebacterium pseudotuberculosis from the sheep used in a research project and the consequently determined serological positivity of these animals indicated the serological examination of the flock from which the sheep came. no symptoms of caseous lymphadenitis were ever observed in the flock in question and no data on the occurrence of this disease were available in the flock history. the sera of 228 head of sheep were used for examinations, while this number of ... | 1994 | 7975051 |

| purification and characterization of an amidase from an acrylamide-degrading rhodococcus sp. | a constitutively expressed aliphatic amidase from a rhodococcus sp. catalyzing acrylamide deamination was purified to electrophoretic homogeneity. the molecular weight of the native enzyme was estimated to be 360,000. upon sodium dodecyl sulfate-polyacrylamide gel electrophoresis, the purified preparation yielded a homogeneous protein band having an apparent molecular weight of about 44,500. the amidase had ph and temperature optima of 8.5 and 40 degrees c, respectively, and its isoelectric poin ... | 1994 | 7944367 |
| pulmonary malacoplakia associated with rhodococcus equi infection in a patient with acquired immunodeficiency syndrome. | pulmonary malacoplakia associated with rhodococcus equi, an opportunistic gram-positive coccobacillus, is unusual. although this patient is the ninth reported to have pulmonary malacoplakia, he is only the third patient with the acquired immunodeficiency syndrome who has been reported to have pulmonary malacoplakia associated with r equi infection. the patient was a 49-year-old man infected with the human immunodeficiency virus who on initial examination was found to have cavitary pneumonia in t ... | 1994 | 7942603 |
| [new macrolides]. | the macrolides are still widely used in general practice and the new 14- or 15 membered-ring compounds-roxithromycin, clarithromycin, dirithromycin, azithromycin -may offer a new development. their antibacterial activity is similar to erythromycin but azithromycin is more active against gram negative strams. roxythromycin exhibits high serum concentrations; azithromycin and dirithromycin present low serum concentrations but prolonged half-lives allowing a reduction of the duration of treatment p ... | 1994 | 7939238 |
| phosphorylative inactivation of rifampicin by nocardia otitidiscaviarum. | rifampicin was inactivated by nocardia otitidiscaviarum to yield two products designated rip-3 and rip-4. the full structures of rip-3 and rip-4 were determined to be 21-(o-phosphoryl) rifampicin and 3-formyl-21-(o-phosphoryl) rifamycin sv, respectively, but neither product had any antimicrobial activity. | 1994 | 7928806 |
| survival and replication of rhodococcus equi in macrophages. | rhodococcus equi is a facultative intracellular bacterium of macrophages that can cause serious pneumonia in both young horses and immunocompromised people. essential to understanding rhodococcus pathogenesis is a quantitative documentation of the intracellular events that follow macrophage phagocytosis of the organism. by using a bacterial immunofluorescence staining assay, we verified the intracellular survival and replicative potential of r. equi in both murine peritoneal macrophages and equi ... | 1994 | 7927672 |
| tamponade due to rhodococcus equi in acquired immunodeficiency syndrome. | infection with rhodococcus equi has been described as a cause of cavitary pneumonia in aids patients. we report such a case, complicated by bacteremia, tamponade, and possible brain and liver abscesses. medical treatment was successful with pericardiocentesis and antibiotherapy with teicoplanin, gentamicin, clarithromycin, rifampicin, supplemented by empirical treatment of cerebral toxoplasmosis. antibiotherapy was terminated after 6 months, without relapse 2 months later. | 1994 | 7924515 |
| detection of a genetic locus encoding resistance to rifampin in mycobacterial cultures and in clinical specimens. | the polymerase chain reaction (pcr) and automated dna sequencing were used to detect a genetic locus, rpob, associated with rifampin resistance in mycobacterium tuberculosis (tb) in clinical isolates and directly in clinical specimens. primers derived from the sequence of a tb rpob gene fragment were used to amplify dna from bacterial and mycobacterial isolates. an rpob-specific pcr product was obtained for five of five tb, seven of eight other mycobacterial species, nocardia sp., corynebacteriu ... | 1994 | 7924218 |
| bacteria and pesticides: a new aspect of interaction--involvement of a new biofactor. | positively charged hydrophobic pesticides of the dipyridyl family [diquat, paraquat, benzylviologen (bv++), etc.] were shown to provoke accumulation of 2-methylbutane-1,2,3,4-tetraol-2,4- cyclopyrophosphate in the cells corynebacterium (brevibacterium) ammoniagenes while neutral dipyridyls were not. hydrophobicity was also an important factor in this phenomenon. of the other pesticides tested, only linuron was effective. bv++ also induced biosynthesis of the compound in rhodococcus rhodochrous, ... | 1994 | 7916959 |
| amidase coupled with low-molecular-mass nitrile hydratase from rhodococcus rhodochrous j1. sequencing and expression of the gene and purification and characterization of the gene product. | the cloned 9.4-kb insert of plasmid pnhj20l containing low-molecular-mass nitrile hydratase (l-nhase) gene from rhodococcus rhodochrous j1 [kobayashi, m. et al. (1991) biochim. biophys. acta 1129, 23-33] was digested with various restriction enzymes, and the trimmed fragments were inserted into puc18 or puc19. a 1.96-kb ecori-sphi region located 1.9-kb downstream of the l-nhase gene was found to be essential for the expression of amidase activity in escherichia coli; the gene arrangement of the ... | 1993 | 7916690 |
| [nosocomial infections: new agents, incidence, prevention]. | nosocomial infection is one of the major health problems confronting clinicians in intensive care units. incidence has been estimated to vary from 5 to 10%, leading to death in one of every 5000 persons hospitalized. this situation is not however static since hospital epidemics and nosocomial infections evolve as a consequence of advances in antibiotic drug therapy and surgical and intensive care techniques. microbial investigations themselves are of major importance as the collection of epidemi ... | 1995 | 7899352 |
| [distribution of alpha-n-acetylgalactosaminidases in marine and freshwater microorganisms]. | the distribution of the alpha-n-acetylgalactosidases producers among 856 marine bacteria isolated from sea water, sediments and associated with sponges, mollusks, echinoderms inhabited in different area of the pacific ocean and 423 baikalian microorganisms from fresh water and sponges have been studied. about 24% as marine as baikalian strains produced this enzyme. the most number of alpha-n-ac-galactosidase producers were found for marine bacteria genera aeromonas, alteromonas and vibrio (71% a ... | 1994 | 7898396 |
| isolation of insertion elements from gram-positive brevibacterium, corynebacterium and rhodococcus strains using the bacillus subtilis sacb gene as a positive selection marker. | the sacb gene of bacillus subtilis was successfully applied in various arthrobacter, brevibacterium, corynebacterium and rhodococcus strains for the isolation of transposable elements. three different insertion sequence (is) elements entrapped in sacb were isolated. the is elements is-bl and is-cg isolated from brevibacterium lactofermentum and corynebacterium glutamicum, respectively, were found to be similar in size (1.45 kb) and generated target duplications of 8 bp. their inverted repeats sh ... | 1995 | 7896070 |
| brevibacterium linens pbl33 and rhodococcus rhodochrous prc1 cryptic plasmids replicate in rhodococcus sp. r312 (formerly brevibacterium sp. r312). | the replication of two cryptic plasmids from brevibacterium linens atcc 9174 (pbl33) and rhodococcus rhodochrous atcc 4276 (prc1) was investigated in rhodococcus sp. r312 (formerly brevibacterium sp. r312). the recombinant plasmids psp33 (pbl33 derivative) and pspc1 (prc1 derivative) were found to be suitable for establishing new host-vector systems for rhodococcus sp. r312. they all carry the tn903 neomycin-resistance-encoding gene (aphi). | 1995 | 7867954 |
| o-, m- and p-hydroxybenzoate degradative pathways in rhodococcus erythropolis. | rhodococcus erythropolis strain s1 uses the gentisate pathway to metabolize salicylate and m-hydroxybenzoate and the protocatechuate pathway to degrade p-hydroxybenzoate. m-hydroxybenzoate 6-hydroxylase was induced by growth on m-hydroxybenzoate or gentisate, and salicylate 5-hydroxylase only by growth on salicylate. p-hydroxybenzoate 3-hydroxylase could be induced only by growth on p-hydroxybenzoate. m-hydroxybenzoate or p-hydroxybenzoate could repress the induction of salicylate 5-hydroxylase. ... | 1995 | 7867918 |
| enzyme-catalysed enantioselective hydrolysis of racemic naproxen nitrile. | the bacterial strain rhodococcus butanica (atcc 21197), which exhibits nitrilase and nitrile hydratase/amidase activities, catalyses the enantioselective hydrolysis of racemic naproxen nitrile (r/s)-1 to furnish a moderate enantiomeric excess of (s)-naproxen (s)-3. racemic naproxen amide (r/s)-2 is not a good substrate for this strain. resting cells of the newly selected bacterial strain rhodococcus sp. c3ii catalyse the enantioselective hydrolyses of racemic naproxen nitrile (r/s)-1 and naproxe ... | 1994 | 7858980 |
| dietzia, a new genus including dietzia maris comb. nov., formerly rhodococcus maris. | sequencing of the 16s ribosomal dnas (rdna) of two strains of rhodococcus maris was performed to determine the relationship of this species to other mycolic acid-containing actinomycetes. for this purpose we also determined the 16s rdna sequences for the type species of the genus rhodococcus, rhodococcus rhodochrous, and for mycobacterium chlorophenolicum (formerly rhodococcus chlorophenolicus), rhodococcus erythropolis, gordona bronchialis, and gordona terrae, for which only partial sequence da ... | 1995 | 7857805 |
| amino acid sequence analysis of ribosomal protein at-l30 from members of the family pseudonocardiaceae. | the phylogenetic relationships of the genera belonging to the family pseudonocardiaceae were examined by a novel approach, amino acid sequencing of ribosomal at-l30 proteins. the results of partial amino acid sequencing of at-l30 preparations revealed that the members of the family pseudonocardiaceae are divided into four clusters; the first cluster contains the genus actinopolyspora, the second cluster contains the genus saccharopolyspora, the third cluster contains the genus amycolatopsis, and ... | 1995 | 7857791 |
| routine identification of mycobacterium tuberculosis complex isolates by automated hybridization. | methodologies for biochemical identification of mycobacteria isolated from clinical samples are still cumbersome, taking skilled technicians 3 to 6 weeks. we describe here a 2-h identification system for mycobacterial isolates belonging to the mycobacterium tuberculosis complex using a dna probe. after 30 min of hands-off sample preparation, the 1.5-h hybridization test is totally automated in the newly developed vidas system (biomérieux, marcyl'etoile, france), which performs solid-phase specif ... | 1994 | 7852560 |
| rhodococcus equi: fatal pneumonia in a patient without aids. | rhodococcus equi infections are being recognized with greater frequency in immunocompromised patients and the population infected with the human immunodeficiency virus (hiv). r. equi usually causes a progressive pneumonia that may or may not cavitate and is relatively refractory to antibiotic therapy. we report a case of fatal r. equi pneumonia in a normal host. | 1994 | 7852068 |
| cytologic appearance of rhodococcus equi in bronchoalveolar lavage specimens. a case report. | immunocompromised patients are at risk of developing infections caused by rhodococcus equi, a gram-positive bacillus that can cause pneumonia in patients with acquired immunodeficiency syndrome. to the author's knowledge this is the first report describing the cytologic features of the infection in a patient who had a confirmatory tissue biopsy and positive culture. infection with r equi may go unrecognized by pathologists unaware of its presentation and appearance in cytologic material. | 1995 | 7846998 |
| rhodococcus equi infection in hiv-positive patients: report of 5 cases and literature overview. | the importance of rhodococcus equi infection, an uncommon human pathogen that almost exclusively affects immunocompromised hosts, has greatly increased following the advent of acquired immune deficiency syndrome (aids) epidemics. until the present time, 38 cases of r. equi infection have been described in human immunodeficiency virus (hiv)-infected patients; we now report a further five personal cases. r. equi was acquired via respiratory exposure to animals in less than half of the patients, an ... | 1994 | 7841972 |
| degradation of the thiocarbamate herbicide eptc (s-ethyl dipropylcarbamothioate) and biosafening by rhodococcus sp. strain ni86/21 involve an inducible cytochrome p-450 system and aldehyde dehydrogenase. | determination of the n-terminal sequences of two eptc (s-ethyl dipropylcarbamothioate)-induced proteins from thiocarbamate-degrading rhodococcus sp. strain ni86/21 resolved by two-dimensional electrophoresis enabled the localization of the respective structural genes on two distinct dna fragments. one of these strongly induced proteins is a nad(+)-dependent dehydrogenase active on aliphatic aldehydes. the second protein was identified as a cytochrome p-450 enzyme. the cytochrome p-450 gene repre ... | 1995 | 7836301 |
