Abstract - Urinary tract infection (UTI) is an important
cause of mortality and morbidity and among the most
common healthcare associated infections. In this study
we described the frequency of occurrence and
antimicrobial susceptibility patterns of nosocomial and
community acquired UTI isolates from a Novus Path
Labs, India and Nepal and its Associates Hospitals. All
patients with a positive urine culture were enrolled.
Antimicrobial susceptibility testing was performed with
disk diffusion and E-test MIC. During the study period,
456 isolates were obtained from urine cultures, from a
total of 8818 collected sets, among which 291 were felt to
represent true bacteremia and 98 were nosocomial.
Acinetobacter spp. were the most frequently isolated
agents in the hospital and community acquired UTIs
(32%), followed by Escherichia coli (13.7%) and
KleUTIella spp. (12%). The most effective antibiotics for
gram-negative and gram-positive bacteria were
ciprofloxacin (13% resistance rate) and vancomycin and
oxacillin (with 13% resistance rate), respectively.
Analysis of antibiotic resistance pattern showed that
20.43% of Acinetobacter spp. and 15.4% of
Pseudomonas aeruginosa were multi drug resistant
(MDR), while 48.7% of KleUTIella spp were ESBL-
producing isolates and 15% of Staphylococcus aureus
were oxacillin-resistant. Not observe any vancomycin-
resistant strains among isolates of S. aureus.
Index Terms - Urinary tract infection, bacterial infection,
antibiotics, antimicrobial susceptibility pattern.
INTRODUCTION
Urinary tract infection (UTI) is an important cause of
mortality and morbidity and among the most common
healthcare associated infections. Wide spectrums of
organisms have been described and this spectrum is
subject to geographical alteration (Diekma DJ, 2003).
In a prospective multicenter study of UTI, Weinstein
et al. noted substantial changes in the microbiology,
epidemiology and clinical and prognostic significance
of positive urine cultures over a 20-year period. They
found that Staphylococcus aureus and Escherichia coli
continued to be the most common etiologic agents of
UTI and noted important increases in UTI due to
coagulase-negative staphylococcus, fungi, and
Pseudomonas aeruginosa (community acquired)
(Winn W, 2006).
One of the more alarming recent trends in infectious
diseases is the increasing frequency of antimicrobial
resistance among microbial pathogens causing
nosocomial and community- acquired infections.
Numerous classes of antimicrobial agents have
become less effective as a result of the emergence of
antimicrobial resistance, often as result of selective
pressure of antimicrobial usage (Garg A, 2007).
These resistance trends and the clinical significance
and changing spectrum of microbial pathogens argue
strongly for antimicrobial resistance surveillance.
Such a program will play a critical role in guiding
physicians toward appropriate agents for use in the
treatment of both community- and hospital-acquired
UTI, as well as identifying changing patterns of
etiologic agents and drug susceptibility. Most previous
studies of UTI have been performed in temperate
developed countries. These studies have mainly
focused on nosocomial infections, especially those
acquired in an intensive care unit (Tien HC, 2007).
In the present study we described the frequency of
occurrence and antimicrobial susceptibility patterns of
nosocomial and community-acquired UTI isolates
from a Novus Path Labs, India and Nepal and its
Associates Hospitals (Munoz-Price L, 2008).
