Patent ID: 7054756

Claim:
A bacteriological examination system for measuring drug sensitivity of bacterial species, comprising: an in-hospital drug-sensitivity statistic database in which statistics of drug sensitivities of a plurality of bacterial species residing in a hospital towards a plurality of drugs are recorded; a regional drug-sensitivity statistic database in which statistics of drug sensitivities of the plurality of bacterial species residing in each region towards the plurality of drugs are recorded; a drug fastness index calculating routine for reading an average-per-sample drug sensitivity with respect to each bacterial species residing in hospital from said in-hospital drug-sensitivity database, for reading an average-per-sample drug sensitivity with respect to the same species of bacteria residing in a region from said regional drug-sensitivity database, for calculating a value by dividing difference between the in-hospital average-per-sample drug sensitivity of the bacterial species and the regional average-per-sample drug sensitivity of the bacterial species by the regional average-per-sample drug sensitivity of the bacterial species, and for averaging respective values of said each bacterial species so as to derive a drug fastness index with respect to the drug; and an output means for outputting the drug fastness index calculated by the drug fastness index calculating routine.
