occurrence of klebisiella pneumoniae in surface waters.the occurrence of klebsiella pneumoniae in surface waters was not found to be ubiquitous. when it was isolated, escherichia coli could also be found. the fecal coliform to fecal streptococci ratio suggest that its origin could be human, animal, or mixed sources.19751096815
inhibition of microbial growth by fatty amine catalysts from polyurethane foam test tube plugs.when polyurethane foam test tube plugs are autoclaved, they release volatile fatty amines that inhibit the growth of some microorganisms. the chemical structures of these amines were determined by the use of a gas chromatograph-mass spectrometer. they are catalysts used to produce the foam. the problem of contaminating growth media with toxic substances released from polymeric materials is discussed.19751096816
malignant hypertension. recovery of kidney function after renal allograft failure.a 28-year old patient with malignant hypertension developed endstage renal failure necessitating chronic maintenance hemodialysis for seven months and transplantation of a renal allograft that was rejected within a month. after this, with continued control of the hypertension, the patient's own kidneys gradually resumed function and achieved anendogenous creatinine clearance of 30 ml/min. she has not required further dialysis for more than nine months. recovery of sufficient renal function to ma ...19751096841
adsorption of pneumocins and aerocins on bacterial cells.adsorption of aerocins 1a-e26, 1b-e47, 1b-e43, 2-e26, 2-e47 and pneumocins a-114 and a-902 was found to be dependent on the presence of specific receptors on the surface of sensitive bacteria. resistant mutants, selected by these bacteriocins, were incapable of adsorption owing to loss or altered structure of receptors. maximal numbers of killing units of pneumocins and aerocins adsorbed by one bacterial cell of sensitive strains were determined. kinetics of adsorption and degree of killing of b ...19751096844
[purification of beta-lactamases by affinity chromatography].affinity columns able to purifie beta-lactamases have been prepared either by linking covalently reversible inhibitors or substrates to agarose beds. the enzyme is eluted with a gradient of sodium chloride or released with the substrate. this method is a pertinent one for the purification of these enzymes and for the study of bacteria harbouring more than one beta-lactamase.19751096966

comparative in vitro acitvity of chloramphenicol and thiamphenicol on common aerobic and anaerobic gram-negative bacilli(salmonella and shigella excluded).the antibacterial activity of thiamphenicol was compared to that of chloramphenicol against 313 strains of gram-negative bacilli isolated from various clinical specimens. these two antiboitics were equally active against the 106 isolates of haemophilus mic equals 0.1 minus 1.56 mu g/ml) and against 40 strains of bacteroides fragilis (almost all strains being inhibited by 12.5 mug/ml of the two drugs). in contrast, when compared with chloramphenicol, 2-16 times as much of thiamphenicol was requir ...19751097209
evaluation of antibacterial activities of cephalosporin antibiotics: cefazolin, cephaloridine, cephalothin, and cephalexin.the antibacterial activities of 4 cephalosporin antibiotics, cefazolin, cephaloridine, cephalothin and cephalexin, against 330 isolates of bacteria from patients at national taiwan university hospital, were determined by an agar plate dilution technique. cephalosporins possess strong antibacterial activity against gram-positive bacteria except enterococci. staphylococcus aureus is the most susceptible among the organisms tested. more than 90% of staphylococcus aureus strains are suppressed by ce ...19751097210
bacterial studies of clindamycin-associated colitis. a preliminary report.the cause of pseudomembraneous colitis is not known but has been attributed to an alteration in the microbial flora of the colon. to test this hypothesis, a blind, prospective study was undertaken in which fecal samples were cultured quantitatively for aerobic and anaerobic organisms. the patients from which these samples were taken were all receiving clindamycin and had diarrhea secondary to the use of the drug. we were able to show definite differences in the colonic microflora which correlate ...19751097297
a field study of coliform mastitis in sows.three sows with agalactia and mastitis were compared with 3 normally lactating sows at 8, 16, 24, and 32 hours postpartum. bacteriologic examination of milk resulted in isolation of klebsiella pneumoniae or escherichia coli from affected glands of all 3 agalactic sows. milk from clinically normal glands of affected sows and from glands of normal sows was culture-negative for coliforms. affected sows had higher rectal temperatures and lower milk yields, and pigs from affected sows had lower mean ...19751097381
genes for ribitol and d-arabitol catabolism in escherichia coli: their loci in c strains and absence in k-12 and b strains.escherichia coli c strains can grow at the expense of the two natural pentitols ribitol and d-arabitol, sugar alcohols previously thought not to be utilized by e. coli. e. coli strains k-12 and b cannot utilize either compound. the genetic loci responsible for pentitol catabolism in e. coli c, designated rtl and atl, are separate and closely linked. each lies between metg and his and is highly co-transducible with metg and with a p2 prophage attachment site. rtl and atl readily can be transduced ...19751097416
radioimmunoassay, acetylating radio-enzymatic assay, and microbioassay of gentamicin: a comparative study.gentamicin is an aminoglycoside antibiotic widely used to treat gram-negative bacillary infections. because it has a low therapeutic index, monitoring of serum levels may help to insure adequacy of dosage and avoid toxicity. microbiological assays are relatively slow and can be complicated by the presence of other antimicrobials. radioimmunoassay (ria) and acetylating radio-enzymatic assay (ara) are new methods for gentamicin assay which offer the following advantages: rapidity (less than 3 hour ...19751097551
