    Abstract:
    Cefotiam (CTM) was administered to female patients suffering from acute cystitis to examine its clinical efficacy and changes in form of the bacteria in urine. CTM was administered to 15 female patients with acute cystitis once a day for three consecutive days (1 g/time in 13 cases, and 0.5 g/time in 2 cases). The overall clinical efficacy was 100%. Bacteriological examination, revealed 13 cases of single infection by E. coli, and one case of E. coli and S. epidermidis (MIC: 0.78 micrograms/ml). MIC of E. coli ranged from 0.05 to 0.78 micrograms/ml. All of the strains were eradicated, the eradication efficacy being 100%. The forms of bacteria in the urine after the administration of CTM were examined in 8 cases (all due to E. coli). Bacteria in urine disappeared or formed a spherical form 5 minutes after the administration of CTM. Disappearance of E. coli was observed in 7 cases at 15 or 30 minutes after drug administration, and with the disappearance, improvements were also observed in the urinary findings. Of these cases, the urinary concentration of CTM was measured in 4 cases. It ranged from 296 to 6,893 micrograms/ml at 5 minutes after the administration. In one case of deficient excretion in urine, filamentation was observed, and with the rise in CTM concentration in urine, granular changes were observed in the shape of bacteria. CTM's excellent clinical efficacy was substantiated by the changes in the form of bacteria in urine.
