Abstract:
Worldwide data show that there is increasing resistance among urinary tract pathogens to conventional drugs. The aim of this study was to obtain data on susceptibility patterns of pathogens responsible for urinary tract infections (UTIs) in Poland to currently used antimicrobial agents. A multicentre study of 141 pathogens from hospital-acquired infections and 460 pathogens from community-acquired infections was carried out between July 1998 and May 1999. The most prevalent aetiological agent was Escherichia coli (73.0%), followed by Proteus spp. (8.9%) and other species of Enterobacteriaceae (9.6%). Few community infections were caused by Gram-positive bacteria (2.2%). Gram-positive cocci were isolated more frequently from a hospital setting (14.1%) and the most common were Enterococcus spp. (8.5%). Pseudomonas aeruginosa was found only among hospital isolates and was responsible for 10.7% of infections. E. coli isolates from both community and hospital infections were highly susceptible to many antimicrobial agents with the exception of those isolates producing extended-spectrum beta-lactamases (ESBLs). Of all Enterobacteriaceae tested, 38 strains (6.9%) were capable of producing ESBLs.
Insights
Urinary tract infection pathogens in Poland show increasing antimicrobial resistance, particularly Escherichia coli strains producing extended-spectrum beta-lactamases (ESBLs). This highlights the need for updated treatment guidelines to combat drug-resistant bacteria.
Area of Science:
- Microbiology
- Infectious Diseases
- Pharmacology
Background:
- Growing global antimicrobial resistance in urinary tract pathogens poses a significant clinical challenge.
- Conventional antimicrobial agents are becoming less effective against common urinary tract infection (UTI) causing bacteria.
Purpose of the Study:
- To assess the antimicrobial susceptibility patterns of UTI pathogens in Poland.
- To identify prevalent etiological agents and their resistance profiles to current antimicrobial drugs.
Main Methods:
- A multicentre study conducted from July 1998 to May 1999.
- Involved analysis of 141 hospital-acquired and 460 community-acquired infection pathogens.
- Identified causative agents including Escherichia coli, Proteus spp., Enterobacteriaceae, Enterococcus spp., and Pseudomonas aeruginosa.
Main Results:
- Escherichia coli was the most common pathogen (73.0%), showing high susceptibility except for extended-spectrum beta-lactamase (ESBL) producing strains.
- 38 strains (6.9%) of Enterobacteriaceae tested produced ESBLs.
- Pseudomonas aeruginosa (10.7%) and Gram-positive cocci like Enterococcus spp. (8.5%) were more frequent in hospital-acquired infections.
Conclusions:
- Escherichia coli remains a primary UTI pathogen in Poland, but ESBL production is a growing concern.
- Antimicrobial susceptibility patterns necessitate careful consideration for effective UTI treatment.
- Monitoring resistance trends is crucial for public health and clinical practice.
