Comparison of Congo Red Agar methods and tube turbidity in biofilm formation in Klebsiella pneumoniae isolates from cases of urinary tract infections in Samen Al-Aeme Hospital Bojnourd
Biofilm can be called a bacterial community that often forms on living or non-living surfaces and is common in natural, industrial, and hospital environments. Klebsiella pneumoniae as a pathogen has the potential to produce biofilms. Understanding biofilm formation in biofilm-forming bacteria is important. The aim of this study was to investigate the biofilm formation in isolates of Klebsiella pneumoniae from urinary tract infections of Samen Al-Aeme Hospital in Bojnourd using two phenotypic
Concord agar and tube turbidity.
The present study examined 30 samples of positive cultures with Klebsiella pneumoniae isolation from patients with urinary tract infections referred to Samen Al-Aeme Hospital in Bojnourd. Biochemical tests such as gram stain, urea, simon citrate, and TSI were performed to confirm the isolates. Isolations for biofilm formation were investigated by the Congo Red Agar method and tube testing.
In this study, 50% of the isolates had strong biofilm and 16.66% had moderate biofilm. Also, in the turbidity method, 33.33% of the pipes had strong biofilm and 40% had medium biofilm.
In the two methods studied, the studied isolates were able to produce biofilm. Due to the production of biofilm in bacteria and its importance in pathogenesis and increasing bacterial resistance against common antibiotics, it is very important to study the production of biofilm.
