influence of referral bias on the clinical characteristics of patients with gram-negative bloodstream infection.summaryreferral bias can influence the results of studies performed at tertiary-care centres. in this study, we evaluated demographic and microbiological factors that influenced referral of patients with gram-negative bloodstream infection (bsi). we identified 2919 and 846 unique patients with gram-negative bsi in a referral cohort of patients treated at mayo clinic hospitals and a population-based cohort of olmsted county, minnesota, residents between 1 january 1998 and 31 december 2007, respec ...201121281552
potential use of shared antigens for immunization against gram-negative bacillary infections.the demonstration of common antigens shared by all enterobacteriaceae has led to evaluation of the effects of immunization of animals and man with these antigens in protecting against bacterial infections and challenge with lps. both active and passive immunization with the re mutant of s. minnesota and the j5 mutant of e. coli afforded significant protection to mice and rabbits against lethal challenge with viable bacteria and heterologous lps. kdo appears to be the antigenic determinant respon ...19806163155

aminoglycoside resistance in gram-negative bacilli during increased amikacin use. comparison of experience in 14 united states hospitals with experience in the minneapolis veterans administration medical center.resistance to amikacin, gentamicin, and tobramycin was surveyed prospectively during controlled aminoglycoside usage in 14 hospitals. following an initial baseline period (minimum, three months) during which gentamicin use predominated, gentamicin and tobramycin were placed on restrictive control, establishing amikacin as the aminoglycoside of general use (86 percent of total aminoglycoside usage). during an average of 35 months' restriction of gentamicin and tobramycin, significant reductions i ...19854025364

organisms encountered in urine cultures over a 10-year period.urinary isolates from 1961 to 1970 were surveyed. forty-four different species were encountered in urine cultures. the most frequently isolated were escherichia coli, klebsiella, enterococci, pseudomonas aeruginosa, and proteus mirabilis.19724622832
regional differences in patterns of urinary tract infections.the identity of 693 pathogenic bacilli isolated from 2,175 urine specimens cultured during a two-year period in southeastern new mexico is presented along with results of sensitivity testing by kirby-bauer technique. the pattern of infections and sensitivity studies in hospitalized patients is compared with that of office patients and contrasted with results noted in other areas.19751096400
