Biochemical Analysis of Germinal Membrane and Cyst Fluid by Raman Spectroscopy in Echinococcosis

Objective:Hydatidosis is a zoonotic parasitic infection caused by the larval stage of Echinococcus granulosus. The aim of this study was to investigate the biochemical structures of germinal membrane and cyst fluids obtained from patients with liver involvement during surgery, by Raman spectroscopy at the molecular level.Methods:Molecular characterization of germinal membrane and cyst fluid according to mitochondrial gene region was determined and phylogenetic analysis was performed. Raman spectroscopy was used in samples and spectral bands between 300 and 1800 cm-1 were examined.Results:As a result of PCR, approximately 400 bp DNA band was obtained from germinal membranes and cyst fluids gathered from patients. Peaks were observed at 780, 880, 970, 1151, 1200, 1270 cm-1 for germinal membrane and at 780 and 1200 cm-1 for cyst fluid. The highest spectral bands were obtained at 1333-1335 cm-1 and were determined to be modes indicating the CH3CH2 collagen and polynucleotide chain.Conclusion:In the identification of microorganisms and biochemical analysis of biological tissues; different diagnostic methods such as molecular, serological and conventional methods are used. In addition to these methods, Raman spectroscopy has been shown in studies to be a fast, non-destructive and noninvasive method. Therefore, it is thought to be an alternative method for analyzing the basic biochemical components of microorganisms at molecular level.
