| ceftriaxone: a beta-lactamase-stable, broad-spectrum cephalosporin with an extended half-life. | ceftriaxone is an aminothiazolyl-oxyimino cephalosporin. it possesses the typical in vitro activity of a third-generation cephalosporin with excellent activity against many gram-negative aerobic bacilli: escherichia coli; species of proteus, klebsiella, morganella, providencia and citrobacter; and enterobacter agglomerans. ceftriaxone also has outstanding bactericidal action against pneumococci, group b streptococci, meningococci, gonococci and hemophilus influenzae. in healthy volunteers, it ha ... | 1985 | 3906584 |
| urinary tract infection in renal transplant patients. | the incidence of urinary tract infections (uti) in 299 renal graft transplantations (281 patients) was analyzed. uti episodes were demonstrated in 185 grafts (62%), most frequently in the first month after transplantation. the infectious episodes were mostly recurrent. persistent infection, detected in 11% of grafts, was associated with urologic complications in almost all cases. no significant correlation between the primary renal disease and the uti rate was found, and there was no significant ... | 1985 | 3905620 |
| use of the hickman catheter for the treatment of lower extremity infections. | the authors discuss the use of a cuffed, silastic catheter, which can be of great value in the reduction of morbidity when dealing with lower extremity infections. when a patient's condition demands the use of long-term antibiotic and/or aminoglyoside therapy, this indwelling central venous catheter can allow easy access to the vascular system and markedly decrease the amount of time the patient has to stay in the hospital. this form of therapy involves the patient in the treatment and displays ... | 1985 | 3905931 |

| development of improved methods for the transport and isolation of haemophilus somnus. | the survival of several strains of haemophilus somnus under various simulated transport conditions was investigated. recovery of h somnus from alginate swabs kept at room temperature was possible for up to 27 hours after sampling, but this period could be extended to 72 hours if the swabs were refrigerated. storage of swabs in transport media did not prolong survival time significantly but did increase the number of bacterial contaminants, thus making recovery of h somnus less likely. the sensit ... | 1985 | 3909276 |

| role of aerobic gram-negative bacilli in endometritis after cesarean section. | endometritis is considered to be a polymicrobial infection, involving aerobes, anaerobes, and genital mycoplasmas. aerobic gram-negative rods make up 7%-25% of all genital isolates, but findings from studies in which special collection techniques were used suggest that many of these may be contaminants from the lower genital tract. bacteremia occurs in 4%-30% of patients with endometritis, and aerobic gram-negative rods account for approximately 25% of blood isolates. both selected therapy studi ... | 1985 | 3909325 |
| [characteristics of various morphological and biological properties of bacteria of the genus proteus]. | the stable o-form of proteus has been found to differ from the initial h-form in the absence of flagellae or in a few weakly developed flagellae, in decreased capacity for agglutination with polyvalent and typing sera and in virulence for laboratory animals. as revealed in this study, the conversion of the h-form of proteus into the stable o-form leads to the loss of resistance to streptomycin, chloramphenicol, tetracycline, monomycin, ampicillin and neomycin. | 1985 | 3907216 |

| influence of rp4 plasmid on extracellular protease secretion by proteus mirabilis. | the transference by conjugation of protease genetic information between proteus mirabilis strains only occurs upon mobilization by a conjugative plasmid such as rp4 (inc p group). upon receiving the rp4 plasmid, the level of proteolytic activity of the protease-excreting p. mirabilis is reduced to about 50%. a similar phenomenon occurs when the protease character is mobilized by the rp4 plasmid from the above transconjugant to a non-protease-excreting recipient strain. the molecular mechanism un ... | 1985 | 3915216 |
| cefmetazole: a broad spectrum cephem antibiotic effective on methicillin- and cephem-resistant staphylococcus aureus. | antibacterial activity of cefmetazole (cmz) was investigated by the plate dilution method. since cmz is stable to any type of bacterial beta-lactamases, it inhibited growth of escherichia coli carrying r plasmids, klebsiella spp., proteus vulgaris, and bacteroides fragilis at the concentration of less than 0.78 to 25.0 micrograms/ml. the distinct characteristic of cmz is its anti-mrsa (methicillin- and cephem-resistant staphylococcus aureus) activity. exclusively in mrsa, a new fraction of penic ... | 1985 | 3915273 |
