[demonstration of antibody-coated bacteria in the urine of pregnant women]. | urinary sediments of 64 pregnant women with significant bacteriuria which has been demonstrated several times before, have been investigated for the presence of antibody coated bacteria. antibody titers were determined in the corresponding serum samples in addition and the results were compared with the clinical diagnosis. in 50% of pregnant women with pyelonephritis antibody coated bacteria could be demonstrated, while 60% of them had elevated serum titers. taking into account both results in 8 ... | 1977 | 331754 |
mercury resistance and r plasmids in clinical isolates of kebsiella pneumoniae. | the mercury and antibiotic resistance of 155 clinical isolates of klebsiella pneumoniae (k. pneumoniae) was determined. resistance to mercury tested was found in 64.5% of the total isolates. the frequencies of resistance to sm, tc, cp, km and gm were 65.8%, 49.0%, 48.4%, 37.4% and 3.9%, respectively. and we selected 94 mercury and drug resistant strains, and they were tested for their ability to transfer the resistance to the mercury and drug sensitive recipients of e. coli k12 ml 1410-nx and e. ... | 1977 | 331756 |
the clinical usefulness of an ongoing bacteremia surveillance program. | surveillance of bacteremic patients within one week of the detection of a positive blood culture provides information of great clinical utility for relatively little effort. in this report one year's experience is reviewed to illustrate that an individual hospital's experience with bacteremia may diverge from national norms. such reviews may also detect recurring errors in medical judgment which may be corrected through proper education. | 1977 | 331951 |
bacteriostatic inhibition of klebsiella pneumoniae by three human transferrins. | three human transferrin variants verified by rivanol precipitation were separated using vertical block polyacrylamide gel electrophoresis followed by elution convection. a bacteriostatic inhibition measurement in vitro of the three transferrins was made. the data indicate that human transferrin variants exhibit different degrees of inhibition on klebsiella pneumoniae. | 1977 | 332055 |
effect of dimethyl sulphoxide on the expression of nitrogen fixation in bacteria. | storage in dimethyl sulphoxide (dmso) of escherichia coli k12 hybrids carrying nif+ genes from klebsiella pneumoniae can result in selection of a defective nitrogen-fixing phenotype. similar results are obtained with e. coli k12 hybrids containing the nitrogen-fixing capacity from rhizobium trifolii. dmso appears to affect particular inner membrane proteins associated with energy metabolism in e. coli k12 and four chromosomal regions (chld, chlg, his and unc) are associated with resistance to dm ... | 1977 | 332135 |
isolation of poly-alpha-l-guluronate lyase from klebsiella aerogenes. | the bacterium klebsiella aerogenes type 25 produces an extracellular alginolyase which has been partly purified. the enzyme is specific for the alpha-l-guluronosyl linkages in whole alginate and fractions therefrom. the end products of its action on polyguluronic acid blocks are mainly the unsaturated di- and tri-saccharides, with a smaller proportion of the homologous tetrasaccharide. some general properties of the enzyme are reported. | 1977 | 332364 |
detection of bacterial infection of the pancreatic ducts in patients with pancreatitis and pancreatic cancer during endoscopic cannulation of the pancreatic duct. | bacterial infections of the pancreas and bacteremia may occur during episodes of pancreatitis. detection of bacterial infections of the pancreas in the past has required laparotomy. the present study was undertaken to determine whether bacterial infection of the pancreas occurred during nonsuppurative pancreatitis. during endoscopic cannulation of the main pancreatic duct, secretin was administered intravenously and pancreatic juice aspirated from within the duct was cultured. bacterial infectio ... | 1977 | 332575 |
immunological interrelationships between cholera toxin and the heat-labile and heat-stable enterotoxins of coliform bacteria. | cholera toxin (ct) and the heat-labile (lt) toxin of escherichia coli are known to share antigenic properties. the present study examined the immunological relationship of ct and the lt and heat-stable (st) toxins of e. coli, klebsiella pneumoniae, and enterobacter cloacae. the neutralizing capacity of equine ct antiserum and of antiserum raised in rabbits to the lt toxin of the three species of coliform bacteria was evaluated by determining their capacity to inhibit the action of purified ct an ... | 1977 | 332637 |

explusion of salibi-clamp from the internal carotied artery in the neck by infection. | a left infraclinoid carotid aneurysm (3 x 2-5 x 2 cm) in a 60-year old woman presented with total ophthalmoplegia and trigeminal symptoms. a staged internal carotied occlusion in the neck was performed using a salibi-clamp. a chronic infectious fistula developed (klebsiella aerogenes). when superficial debridement failed, operative removal of the salibi-clamp was planned seven months after its insertion. the clamp was found subcutaneously without any relation to the internal carotid artery and w ... | 1977 | 333303 |
the role of plasma cells in scleroma. electron-microscopic study. | three cases of rhinoscleroma in the granulomatous stage were examined under the electrom microscope. the rough endoplasmic reticulum of plasma cells in scleroma displayed cisternal dilatations forming russell bodies and cytoplasmic vacuolations containing viable and degenerated bacilli forming mikulicz cells. thus, they play a double role, producing antibodies and providing protection for the intracellular bacilli. new ultrastructural findings of klebsiella rhinoscleromatic bacilli were describe ... | 1977 | 333340 |

acriflavine violet red bile agar for the isolation of klebsiella. | a medium for the isolation and detection of klebsiella is described. it contains 0.06% acriflavine in violet red bile agar (difco). klebsiella appeared as 5 to 7 mm mucoid (24 h at 37 degrees c) golden-yellow colonies. pseudomonas aeruginosa and enterobacter spp. appeared as small, brown to dark brown colonies. escherichia coli as well as many other gram negative organisms and gram positive organisms did not grow on this medium. | 1977 | 334697 |
intramammary infections in a dairy herd with a low incidence of streptococcus agalactiae and staphylococcus aureus infections. | in a dairy herd with a low incidence of intrammary infections due to streptococcus agalactiae and staphylococcus aureus, clinical mastitis remained a serious problem despite good control of nonclinical mastitis through postmilking teat disinfection and antibiotic therapy of known infected quarters at the end of lactation. during the 2-year study, the incidence of clinical mastitis was 0.88 cases/cow-year; 32.2% were caused by streptococcal species other than str agalactiae and 33.5% by gram-nega ... | 1977 | 334713 |
reactivity and inhibitor potential of hydroxycitrate isomers with citrate synthase, citrate lyase, and atp citrate lyase. | the four isomers of hydroxycitrate have been tested as substrates and inhibitors for citrate synthase, citrate lyase, and atp citrate lyase. none of the isomers served as a substrate for citrate synthase and they were moderate to weak inhibitors of this reaction. of the four isomers, only (pncit)-(2s)-2-hydroxycitrate did not serve as a substrate for citrate lyase while (pncit)-(4s)-4-hydroxycitrate was the only isomer which did not serve as a substrate for atp citrate lyase. no consistent patte ... | 1977 | 334761 |
enzymatic degradation of polygalacturonic acid by yersinia and klebsiella species in relation to clinical laboratory procedures. | as scored by several specified plating procedures, clinical and environmental strains of yersinia enterocolitica, yersinia pseudotuberculosis, and klebsiella pneumoniae "oxytocum" showed detectable, albeit generally weak, ability to digest polygalacturonic (pectic) acid. none of these bacterial strains had the vigorous and rapid pectolytic activity on these polygalacturonic acid-containing media that is typical of soft-rot erwinia species, although some of the oxytocum strains came fairly close. ... | 1977 | 334794 |
