Summary: | Introduction: Urinary tract infections as a result of Candida
species are becoming increasingly common in hospital settings.
The association is higher in patients with prolonged urinary
catheterization and also various pre-disposing factors.
Aim: This study was done to look into the significance of
candiduria in the catheterized patients and to perform microbial
catheterization of yeast and biofilm detection by tube method to
guide treatment protocol.
Materials and Methods: This is a prospective study. One hundred
urine samples were collected over a period of 3 months. Specimens
included were those of patients presenting with nosocomial Urinary
tract infection (UTI) after 72 hours of hospitalization. The urine samples
obtained were immediately processed in microbiology laboratory by
semi-quantitative method as per standard protocol. All yeast isolates
were stored for further microbial characterization. Biofilm production
was detected by tube method.
Results: In the present study we observed that out of 100 samples
obtained from catheterized patients presenting with nosocomial UTI
26% were caused by Candida species. Among the 26 Candida isolates
16 (61.53%) were non albicans Candida and 10(38.47%) were Candida
albicans. Out 26 Candida isolates, 14(53.84%) of the candida isolates
were found to produce biofilm. Biofilm production was found to occur
more frequently among non albicans Candida 10(62.5%) than Candida
albicans 4(40.0%).
Conclusion: The present study reiterates the presence of candiduria
in catheterized patients. Non-albicans candida speices are replacing
candida albicans as the predominant pathogen for nosocomial UTI. It
was also observed that Biofilm formation is seen more frequently with
non albicans candida species than with Candida albicans. |
