hydrolytic rate at low drug concentration as a limiting factor in resistance to newer cephalosporins.hydrolysis kinetics of two cephalosporinases from citrobacter freundii and proteus vulgaris having different affinities for cefotaxime and ceftazidime was assessed in studies with cefotaxime, ceftazidime, bmy-28142, and imipenem. the two cephalosporinase genes were cloned into strains of escherichia coli. the production of these cephalosporinases in strains of e. coli, as well as in the derepressed mutants of c. freundii and p. vulgaris, caused a decrease in susceptibility to the newer cephalosp ...19883055173
inducible beta-lactamases: clinical and epidemiologic implications for use of newer cephalosporins.the emergence of resistance to multiple beta-lactam antibiotics is a major problem in patients infected with organisms that characteristically produce inducible beta-lactamases--e.g., species of pseudomonas, enterobacter, serratia, citrobacter, indole-positive proteus, and providencia. resistance has emerged in 14%-56% of patients infected with these organisms and treated with one of the newer cephalosporins. the emergence of resistance has been associated with clinical failure or relapse in 25% ...19883055176
paradoxical antibacterial activities of beta-lactams against proteus vulgaris: mechanism of the paradoxical effect.fifteen beta-lactam antibiotics were divided into four classes based on their antibacterial actions and beta-lactamase-inducing activities in proteus vulgaris. one of these groups, which included cefmenoxime, ceftriaxone, cefuzonam, and cefotaxime, showed a clear paradoxical antibacterial activity against p. vulgaris. this group showed growth-inhibitory activity at relatively low concentrations, up to certain limits. these cephalosporins have, as a common moiety, an aminothiazolyl-oxyimino group ...19883056246
[immunomodulating therapy of adjuvant disease in rats using cyclophosphamide in combination with prodigiozan--its effect on anti-infectious resistance].the effect of immunomodulating therapy of adjuvant disease in rats with cyclophosphamide, prodigiozan and their combinations on infection resistance, weight of the lymphoid organs and leukocyte counts in peripheral blood, as well as the effect of prodigiozan on acute toxicity of cyclophosphamide in intact mice and mice exposed to the freund's complete adjuvant (fca) was studied. prodigiozan did not increase acute toxicity of cyclophosphamide in the intact mice. it lowered the cyclophosphamide to ...19883056303
brain abscesses in neonates. a study of 30 cases.since the introduction of ultrasonography and computerized tomography (ct) scanning, brain abscesses are found more frequently in cases of neonatal meningitis and septicemia, particularly when the offending pathogen is proteus. thirty cases of brain abscess in neonates are reported, 27 of which were caused by proteus species infections. twenty infants had meningitis and 13 had septicemia. most of the abscesses were enormous, and multiple abscesses were observed in 17 cases. the frontal region wa ...19883057126
variable in vitro activity of cefaclor, cephalothin and cefadroxil against escherichia coli, klebsiella pneumoniae and proteus mirabilis.the in vitro activity of cefaclor, cephalothin and cefadroxil to 50 escherichia coli, 23 klebsiella pneumoniae and 20 proteus mirabilis strains was tested with the disc diffusion and microdilution plate techniques. cefaclor was more active than cefadroxil, while cephalothin was intermediate. the differences seriously affected the classification into the routine sir system. for susceptibility testing we question the use of cephalothin as a class representative of oral cephalosporins.19883057617
chromosomal beta-lactamase expression and resistance to beta-lactam antibiotics in proteus vulgaris and morganella morganii.indole-positive members of the proteeae usually have inducible expression of chromosomal beta-lactamases. mutants with stably derepressed beta-lactamase expression occur in inducible populations at frequencies in the range of 10(-6) to 10(-8). the contribution of these beta-lactamases to drug resistance was examined in morganella morganii and proteus vulgaris. the m. morganii enzyme was a high-molecular-weight (49,000) class i cephalosporinase with low vmax rates for ampicillin, carbenicillin, a ...19883058021
