Background: Microbial cells growing in biofilms, play a huge role in the spread of antimicrobial resistance. In this study, biofilm
formation of
Klebsiella
strains belonging to 3 different
Klebsiella species (
K. ornithinolytica, K. oxytoca and K. terrigena),
cooccurences’ effect on biofilm formation amount and anti-biofilm effects of
Citrus limon and
Zingiber officinale essential oils on
biofilm formations of highest biofilm forming
K. ornithinolytica, K. oxytoca and K. terrigena strains were determined.
Materials and Methods: Anti-biofilm effects of
Citrus limon and
Zingiber officinale essential oils on biofilm formations of highest
biofilm forming
K. ornithinolytica, K. oxytoca and K. terrigena strains were investigated.
Results: 57% of
K. ornithinolytica strains and 50% of
K. oxytoca strains were found as Strong Biofilm Forming (SBF), there wasn’t
any SBF strain in
K. terrigena species. In addition to this, clinical materials of urine and sperm were found as the most frequent
clinical materials for strong biofilm forming
K. ornithinolytica and
K. oxytoca isolations respectively (63%; 100%) Secondly, all
K. ornithinolytica strains isolated from surgical intensive care unit and all
K. oxytoca strains isolated from service units of urology
were found as SBF. Apart from these, although the amount of biofilm, formed by co-occurence of
K. ornithinolytica -
K. oxytoca
and
K. oxytoca -
K. terrigena were more than the amount of biofilm formed by themselves separately, biofilm formation amount of
co-occurrence of
K. ornitholytica -
K. terrigena strains was lower than biofilm formation amount of
K. ornithinolytica but higher
than biofilm formation amount of
K. terrigena.
Conclusion: The antibiofilm effects of
Citrus limonum and
Zingiber officinale essential oils could be used against biofilm
Klebsiella aquired infections.
