Abstract
We examined 834 isolates of urinary cultures (26 fungi and 808 isolates from 28 bacteria) in an academic geriatric teaching hospital for microbial spectrum and resistance analysis. Of the bacteria, 90% were associated to ten species. Detection rate of MRSA and ESBL was 1%, detection rate for pseudomonas aeruginosa, proteus species, coagulase negative staphylococci and klebsiella species were higher than in an university clinic (p < 0.001). Resistency rates were high for the 10 most frequent bacteria: 53.3% of cross-tabulations between bacterium and antibiotic agent (sulfamethoxazol-trimethoprim, amoxicillin-clavulanate, ciprofloxacin, moxifloxacin, cefuroxim, imipenem) showed resistency rate higher than 10%. We assume that specific factors of geriatric sample taking have an impact to our 2-year resistogram results. It is necessary to combine data analysis from comprehensive geriatric assessment and microbiological methods.
