Antimicrobial resistance
among bacterial
pathogens isolated from
UTIs

Introduction
 Among the 10 leading causes of death,
infections are considered the number
one in the low income countries and the
fourth killer in the developed countries.
 Most of the infections are caused by
bacteria
 Antibiotics are the only drugs for these
bacterial diseases
• Urinary Tract Infection (UTI) is the most
common infectious diseases diagnosed in
outpatients.
• Reporting of antimicrobial susceptibility
testing is usually achieved in 48 h.
• The treatment decision is empirical, being
influenced by available data reflecting
antibiotic resistance.
• Knowledge of the antimicrobial resistance
patterns of common uropathogens is
essential to provide clinically appropriate
and cost effective therapy.
Aims of study
1. To determine the frequency of the
uropathogens
2. To determine the susceptibility of these
isolates to commonly used and newer
antimicrobial agents.
• A prospective study was conducted on bacteria
isolated from the urine of patients with UTI in the
city of Nablus, Palestine.

Spread of antibiotic resistance
Recommendations
1. Surveillance program of antibiotic
resistance
2. Local guidelines
3. Responsible use of antibiotics
