| comparative evaluation of five aminoglycosides for treatment. | gentamicin, tobramycin, sisomicin, amikacin and kanamycin are compared for therapeutic use by correlating the in vitro minimal inhibitory concentration with the in vivo concentration of the antibiotic attainable in the serum at half the time intervall between two administrations of the drugs. using this method of evaluation, e. coli, enterobacter and sensitive strains of the klebsiella and pseudomonas species can be treated in principle equally well with gentamicin, tobramycin and sisomicin, and ... | 1976 | 820656 |
| antibacterial activity of selected beta-lactam and aminoglycoside antibiotics against cephalothin-resistant enterobacteriaceae. | the in vitro antibacterial activity of four beta-lactam antibiotics (cefatrizine [bl-s640], cefamandole, cefoxitin, and carbenicillin) and three aminoglycosides (amikacin, gentamicin, and tobramycin) was determined against 197 strains of cephalothin-resistant enterobacteriaceae. eighty strains were found to be gentamicin-sensitive, and 117 were found to be gentamicin-resistant. carbenicillin was the most active beta-lactam antibiotic against gentamicin-sensitive serratia marcescens and enterobac ... | 1976 | 949175 |
| providencia stuartii, a hospital pathogen: potential factors for its emergence and transmission. | the emergence of providencia stuartii as a hospital pathogen in a burn unit was demonstrated by routine infection surveillance. the organism was initially recognized in a burn wound and subsequently in urine or sputum. compared to controls, those patients harboring p. stuartii were similar in age and percentage of body surface burned and were more likely to have been in one of the two burn unit rooms, (p less than 0.02). infection with p. stuartii was independent of duration in the intensive car ... | 1976 | 952286 |
