The Prevalence of Ampicillin, Cephalosporin and Sulphonamide Resistance amongst Urinary Tract Pathogens
A total of 2,031 clinical isolates of Gram negative bacilli was obtained from hospitals in 4 centres and these cultures were tested for resistance to ampicillin, cephazolin and sulphonamide.
Ampicillin and sulphonamide resistance in outpatients ranged from 15–28% of Esch. coli strains and 4–11% of Proteus mirabilis strains. Resistance to cephazolin in outpatients ranged from 0–3% of Esch. coli and 0–6% for Proteus mirabilis. Resistance patterns for Esch. coli, Proteus mirabilis and Klebsiella strains isolated from inpatients were much higher and varied widely.
These patterns are presented and the reasons for these variations discussed.
