Kopsavilkums
Pieaugošās antimikrobiālās rezistences dēļ, Klebsiella pneumoniae, kuras multirezistence pieaug, būtiski sarežģi infekciju ārstēšanu. Darba mērķis ir izvērtēt nitrofurānu un bakteriofāgu kombinētās terapijas efektivitāti pret K. pneumoniae. Kā nitrofurāns tika izvēlēts Furasols jeb furagīns. Furasols ir medikaments, kas tiek ražots Latvijā un to var iegādāties aptiekā bez receptes. Tika veikta padziļināta literatūras apskate par nitrofurāniem, antimikrobās rezistences problēmu, bakteriofāgiem, kā arī bakteriofāgu un nitrofurānu stabilitātes aspektiem. Veiktajos eksperimentos tika noteikta furagīna minimālā inhibējošā koncentrācija (MIC) pret K. pneumoniae kā arī, fāga-antibiotikas mijiedarbība izmantojot režģveida atšķaidījuma testu. Baktēriju augšana tika noteikta pēc optiskā blīvuma vērtībām.
Rezultāti uzrāda, ka bakteriofāga-furagīna sinerģija pastāv, kombinācija kavē baktērijas augšanu efektīvāk nekā katrs līdzeklis atsevišķi. Kombinētai terapijai ar nitrofurānu un bakteriofāgu ir perspektīva cīņā pret multirezistentiem K. pneumoniae celmiem. Antagonisms starp bakteriofāgu un furagīnu netika novērots. Bakteriofāgs furagīna klātbūtnē saglabāja virulenci.
Due to the increasing antimicrobial resistance, Klebsiella pneumoniae, whose multidrug resistance is on the rise, significantly complicates infection treatment. The aim of this study was to evaluate the effectiveness of combined nitrofuran and bacteriophage therapy against K. pneumoniae. Furasol, also known as furagin, was chosen as the nitrofuran. Furasol is a medication produced in Latvia and available over-the-counter in pharmacies. An extensive literature review on nitrofurans, antimicrobial resistance issues, bacteriophages, nitrofuran-phages stability was conducted. Experiments determined the minimum inhibitory concentration (MIC) of furagin against K. pneumoniae, and the interaction of phage-antibiotic using the checkerboard assay. Bacterial growth was assessed through optical density measurements. Results indicated the existence of synergism between bacteriophage and furagin; the combination inhibited bacterial growth more effectively than either agent alone. Combined nitrofuran and bacteriophage therapy shows promise against multidrug-resistant K. pneumoniae strains. No antagonism was observed between the bacteriophage and furagin. The bacteriophage retained its virulence in the presence of furagin.
