| the occurrence of the trehalose fermenting, tetracycline and polymyxin resistant phenotype among the enterobacteriaceae. | in proteus morganii, p. mirabilis, and providencia stuartii the ability to ferment trehalose and resistance to tetracycline were associated in 90%-97% of the strains. the same was true of at least 78% of the strains of serratia marcescens. proteus vulgaris showed a more quantitative association of the two traits. as the characters occur independently in 3-10% of the strains, the association is considered to be due to simultaneous selection in some natural niche. the trehalose fermenting, tetracy ... | 1980 | 6251697 |
| comparative in vitro activities of cefotaxime and ceftizoxime (fk749): new cephalosporins with exceptional potency. | cefotaxime and its desacetoxymethyl derivative, ceftizoxime (previously known as fk749), are both extremely active against a wide spectrum of bacteria. in the present comparative study, the activity of ceftizoxime exceeded that of cefotaxime by a factor of four or more for strains of klebsiella, enterobacter, providencia, serratia, and bacteroides; the only species for which the activity of cefotaxime exceeded that of ceftizoxime by a factor of four was vibrio cholerae. against other species, th ... | 1980 | 6252829 |
| a comparison of dna cleavage by the restriction enzymes salpi and psti. | methods for obtaining highly active, exonuclease-free, stable preparations of the streptomyces albus p restriction enzyme salpi are described. salpi and its isoschizomer psti (from the taxonomically distant providencia stuartii 164) both cleave their recognition sequence (5'-ctgcag-3') to generate fragments terminating in tetranucleotide 3' extensions whose sequence is 5'-tgca-3'. bacteriophage r4g2 dna, protected against salpi cleavage by pregrowth on s. albus p, is also protected against psti ... | 1980 | 6255438 |

| mechanisms of in vitro sensitivity to sulfadiazine silver. | sulfonamide-resistant organisms have been reported as a frequent consequence of the clinical use of sulfadiazine silver. at this burn center, sulfonamide resistance occurred in more than 80% of gram-negative isolates. we tested the requirement for the individual antimicrobial activities of sulfadiazine and silver for the vitro activity of sulfadiazine silver. the sulfadiazine component is not necessary for in vitro sensitivity. in vitro sensitivity to sulfadiazine silver does not consistently pr ... | 1983 | 6401421 |
| the condom catheter: urinary tract infection and other complications. | a retrospective study of 64 geriatric patients on an extended care unit at the va medical center strongly suggested that long-term use of a condom catheter drainage system (ccds) (mean use, 35 months) was regularly associated with urinary tract infection. common nosocomial pathogens were found, particularly proteus-providencia. the ccds was also associated with significant penile complications. it is hoped that these hazards can be minimized by careful application and monitoring of the ccds. | 1983 | 6405482 |
