enzymes of agmatine degradation and the control of their synthesis in klebsiella aerogenes. | the degradation of agmatine to succinate by klebsiella aerogenes occurs in five steps. the enzyme catalyzing the first step, agmatinase, is induced by agmatine. the enzymes catalyzing the second and third steps, putrescine aminotransferase and 4-aminobutyraldehyde dehydrogenase, are induced by putrescine and also by their product, 4-aminobutyrate. the enzymes catalyzing the fourth and fifth steps, 4-aminobutyrate aminotransferase and succinate semialdehyde dehydrogenase, are induced by 4-aminobu ... | 1979 | 35512 |
relation between the adenylylation state of glutamine synthetase and the expression of other genes involved in nitrogen metabolism. | we have partially characterized the biochemical parameters of glutamine synthetase from klebsiella pneumoniae and have shown that the differential affinity of adenylylated and unadenylylated glutamine synthetase for adenosine diphosphate provides a convenient means of determining the adenylylation state. using this assay procedure, we examined the relationship between the adenylylation state and the expression of other genes involved in nitrogen assimilation. we observed no correlation between t ... | 1979 | 35515 |
cefuroxime: a review of its antibacterial activity, pharmacological properties and therapeutic use. | cefuroxime is a new semisynthetic cephalosporin for parenteral administration. it is resistant to destruction by beta-lactamases produced by staphylococci and most gram-negative aerobic bacteria and is active against many bacteria resistant to cephalothin. cefuroxime is the most active of the cephalosporins against gonococci and haemophilus influenzae particularly against beta-lactamase producing strains. given by intramuscular or intravenous injection cefuroxime is effective against a wide vari ... | 1979 | 37064 |
intradermal responses to common bacterial antigens: influences of sex and clinical condition. | intradermal responses to antigens of 12 common bacteria were evaluated in 218 dermatologic and 155 respiratory patients. women responded more frequently than men and respiratory patients responded significantly more frequently than dermatologic patients to certain antigens. interpretation of interspecies associations of responses suggested that certain organisms may be key species in the development of bacterial hypersensitivity. | 1979 | 37788 |
ps-5, a new beta-lactam antibiotic. ii. antimicrobial activity. | ps-5, a new beta-lactam antibiotic, has relatively potent antimicrobial activity against gram-positive and gram-negative bacteria, especially the enterobacter groups, serratia marcescens, the proteus groups and klebsiella pneumoniae. the activity of ps-5 against many beta-lactamase-producing organisms is greater than that of cefoxitin or cefazolin. ps-5 has good therapeutic activity in mice infected with staphylococcus aureus smith or enterobacter cloacae 45. | 1979 | 38238 |
detection of experimental bacteremia and fungemia by examination of buffy coat prepared by a micromethod. | rabbits received intravenous injections of bacteria or fungi, and a comparison was made of the abilities of broth cultures, plating after dilution either in saline solution or in distilled water containing triton x-100, and buffy coat examinations to detect the organisms in heart blood. the most sensitive method was broth culture. by microscopy or subculture of buffy coat cells prepared by centrifugation of blood in microhematocrit tubes, organisms were rapidly and regularly detected when their ... | 1979 | 38662 |
distinctive properties of glutamine synthetase from the cyanobacterium anacystis nidulans. | the intracellular levels of glutamine synthetase (gs) in anacystis nidulans grown under different conditions were determined using a whole-cell assay. nitrate-grown cells have 64% more gs than cells grown in ammonium sulfate. nitrogen starvation does not affect gs levels appreciably. incubation of nitrate-grown cells with ammonium sulfate does not change the ratio of gamma-glutamyl transferase activities stimulated by mg2+ and mn2+ ions. an in vitro test of adenylylation indicates that algae do ... | 1979 | 38892 |
the role of bacterial interference in the increased prevalence of oropharyngeal gram-negative bacilli among alcoholics and diabetics. | the oral flora of alcoholics, diabetics, and normal control subjects were compared using an agar overlay technique to determine whether the increased prevalence of oropharyngeal gram-negative bacilli among alcoholics and diabetics exists because patients with these diseases have decreased numbers of normal inhibitory bacteria in the oropharynx. alcoholics generally had slightly lower concentrations of inhibitory bacteria than control subjects, and diabetics had somewhat higher concentrations tha ... | 1979 | 39482 |
microbiological activity of cefazedone as compared to cefazolin and cephalothin. | in a comparison of the antibacterial activity of (6r,7r)-7-(2-[3,5-dichloro-4-oxo-1(4h)-pyridyl]-acetamido)-3-([5-methyl-1,3,4-thiadiazol-2-yl)-thio]methyl)-8-oxo-5-thia-1-azabicyclo[4,2,0]oct-2-ene-2-carboxylic acid (cefazedone, refosporen) as compared to other cephalosporins it can be seen that cefazedone possesses good activity against gram-positive bacteria; as regards activity against enterobacteriaceae, in particular strains of e. coli, klebsiella species and proteus mirabilis, they fall w ... | 1979 | 39575 |
evidence for pili-mediated adherence of klebsiella pneumoniae to rat bladder epithelial cells in vitro. | the possible role of pili in the pathogenesis of urinary tract infections caused by klebsiella pneumoniae was studied in an in vitro mixture of a phosphate-buffered saline suspension of rat bladder epithelial cells and phosphate-buffered saline-washed k. pneumoniae. nonpiliated and piliated populations derived from a single k. pneumoniae strain were obtained by controlling the total time of growth in broth medium. the piliated phase demonstrated a significant increase in adherence when compared ... | 1979 | 39895 |
polymicrobial bacteremia. | of 26,961 blood cultures taken during an 18-month period at the cincinnati general hospital, 1,715 (6%) were positive. ninety-four patients had blood cultures containing more than one organism. although aerobic and anaerobic streptococci were the most frequently isolated bacteria, a variety of microorganisms, including staphylococcus aureus and the klebsiella-enterobacter-serratia group, was isolated in different combinations depending on the underlying disease. neurological illness, malignant n ... | 1979 | 40048 |

glutamine synthetase mutations which affect expression of nitrogen fixation genes in klebsiella pneumoniae. | previous studies have implicated glutamine synthetase (l-glutamate:ammonia ligase [adenosine diphosphate for-ing], ec 6.6.1.2) as a major controlling element of the nitrogen fixation (nif) genes in klebsiella pneumoniae. we report here the isolation of a new class of k. pneumoniae mutants which exhibit altered patterns of nif and hut (histidine utlization) regulation. the expression of nif in these mutants, which were isolated as gln+ (glutamine nonrequiring) revertants of a particular glna muta ... | 1979 | 40960 |
interferon and cytotoxic factor (cytotoxin) released in the blood of mice infected with mycobacterium bovis bcg. i. enhanced production of interferon and appearance of cytotoxin stimulated by capsular polysaccharide of klebsiella pneumoniae or bacterial lipopolysaccharide. | interferon production stimulated by the active substance (neutral fraction) of the capsular polysaccharide of klebsiella pneumoniae (neutral cps-k) in bcg-infected mice was compared with that by bacterial lipopolysaccharide (lps). prior infection with bcg increased the responsiveness of mice to the lethal effect of neutral cps-k as well as to that of lps. associated with this, bcg-infected mice showed a markedly enhanced ability to produce interferon after stimulation not only by lps but also by ... | 1979 | 41163 |
resistance of gram-negative bacteria to antibiotics in large calf agglomerations. | the antibiotic resistance of e. coli, citrobacter, enterobacter-klebsiella and pseudomonas aeruginosa strains isolated from calves was tested. a high proportion of multiresistance was found even in e. coli strains isolated from newborn calves. gram-negative bacteria isolated from animals in three large calfhouses were almost 100% resistant to ampicillin, tetracyclines and sulphonamides. multiresistance was general and varied from 5 to 12 antibiotics among different strains. initial high sensitiv ... | 1979 | 41425 |
[a clinical observation of cefuroxime in pediatric field (author's transl)]. | cefuroxime, a new synthetic cephalosporin, was administered to 10 pediatric patients (6 with respiratory tract infection, 2 with urinary tract infection, 1 with sepsis of e. coli and 1 with enterocolitis). the clinical result was good and excellent in all the 10 cases. no side effect was observed in any of them. | 1979 | 41955 |
evolution of enzyme structure. | three-dimensional structures of enzymes offer evidence about their evolution. there are clear examples of divergent families (e.g. mammalian serine proteases) and convergence (e.g. chymotrypsin and subtilisin). topological similarities in dehydrogenases may reflect an ancient divergence or merely chemical constraints on protein architectures. further experimental evidence is desirable to back up arguments based on molecular morphology. by growing microorganisms on novel foodstuffs in a chemostat ... | 1979 | 42054 |
