clinical and microbiologic consequences of amikacin use during a 42-month june 1980, 23% of our pseudomonas aeruginosa isolates and 53% of our serratia species were resistant to gentamicin and tobramycin. during a 3 1/2-year period of almost exclusive amikacin usage, we noted a fall in overall resistance of gram-negative organisms to tobramycin and gentamicin from 18.8% and 19.3% to 15.2% and 16.2%, respectively. this fall in resistance was most notable for escherichia coli, proteus mirabilis, and serratia species. during this period there was no increase in amikac ...19863954526

metabolic variations of proteus in the memphis area and other geographical areas.the number of strains of proteus studied was 413, and these were obtained from all clinical materials with the exception of fecal specimens. lactose was fermented by 37 strains (p. inconstans, 29%; p. rettgeri, 16%; p. mirabilis, 4.2%; p. morganii, 3.6%; and p. vulgaris, 0%) of which 33 were from the genitourinary system. these 33 strains constituted 12.7% of the 260 strains isolated from this source. biochemically, p. mirabilis was the least variable, and p. rettgeri was the most variable of th ...19685664111
nosocomial infection with highly resistant, proteus rettgeri. report of an epidemic.over 22-1/2 months an epidemic of at least 127 cases of nosocomial infection developed from a strain of proteus rettgeri resistant to all antibiotics commonly tested in hospital laboratories. although there were at least four cases of septicemia and one related death, the majority of cases consisted of asymptomatic bacteriuria or clinically mild urinary tract infection. indwelling urinary tract devices and antibiotic therapy were important predisposing factors. data supported an association betw ...1976961694
