Emerging antibiotic resistance among the uropathogens

Area of Science:

• Clinical microbiology
• Infectious diseases
• Public health

Background:

• Urinary tract infections (UTIs) are common, necessitating ongoing surveillance of causative pathogens and their antibiotic susceptibility.
• Antimicrobial resistance (AMR) poses a significant global health threat, particularly in hospital settings.

Purpose of the Study:

• To analyze the culture positivity rate and identify common uropathogens in clinically suspected UTI cases.
• To investigate the antibiotic sensitivity patterns of uropathogens and track the emergence of drug resistance over time.
• To assess the impact of antibiotic usage on the development of resistant bacterial strains.

Main Methods:

• Retrospective analysis of 18,876 urine samples collected between 1997 and 1998.
• Microbiological culture and identification of uropathogens.
• Antibiotic sensitivity testing (AST) to determine susceptibility patterns.

Main Results:

• A culture positivity rate of 37% was observed among the analyzed samples.
• An increasing incidence of Proteus species was noted in 1998, particularly in hospitalized patients.
• Withdrawal of certain antibiotics led to the re-emergence of sensitive strains, while the overuse of newer agents like amikacin and netilimicin contributed to resistance.

Conclusions:

• Antibiotic stewardship is crucial to manage and prevent the spread of antimicrobial resistance.
• The study underscores the urgent need for a comprehensive national antibiotic policy to guide rational drug use.
• Monitoring antibiotic resistance trends is essential for effective UTI management and public health protection.
