Περίληψη

Η κυστική εχινοκοκκίαση (CE) είναι μια παρασιτική ζωονόσος που προκαλείται από την προνύμφη Echinococcus granulosus sensu lato. Η παρούσα μελέτη διεξήχθη για τον μοριακό χαρακτηρισμό των κύστεων CE που ελήφθησαν από έναν γάιδαρο που είχε μολυνθεί φυσικά με κύστεις CE και για τον προσδιορισμό της ποικιλομορφίας των απλοτύπων. Διερευνήθηκαν δέκα μεμονωμένες κύστεις CE που εντοπίστηκαν στο ήπαρ ενός γαϊδάρου. Το γονιδιωματικό DNA εξήχθη από κάθε μεμονωμένη απομόνωση κύστης. Προϊόν PCR τμήματος 875 bp του μιτοχονδριακού γονιδίου της υπομονάδας 1 της κυτοχρωμικής οξειδάσης c (mt-CO1) ενισχύθηκε με τη χρήση ειδικών εκκινητών. Τα προϊόντα PCR καθαρίστηκαν και πραγματοποιήθηκε ανάλυση της αλληλουχίας. Οι μερικές αλληλουχίες του γονιδίου mt-CO1 που ανήκουν στις απομονώσεις της κύστης CE συγκρίθηκαν με τις δημοσιευμένες αλληλουχίες αναφοράς. Οι μερικές αλληλουχίες του mt-CO1 ταυτοποιήθηκαν ως E. equinus. Μετά από ανάλυση απλοτύπων, ταυτοποιήθηκαν δύο διαφορετικοί απλότυποι (Hap01 και Hap02). Εννέα αλληλουχίες που προέκυψαν από την παρούσα μελέτη ανήκαν στον κύριο απλότυπο (Hap01)- ωστόσο, μια άλλη αλληλουχία γαϊδούρας από την παρούσα μελέτη εντοπίστηκε στον Hap02 με νουκλεοτιδική διαφορά. Παρόλο που ο Echinococcus granulosus s.s. (G1 και G3) αναφέρεται ότι είναι το κυρίαρχο είδος και τα τρέχοντα ευρήματα έδειξαν ότι ο E. equinus (G4) και οι απλότυποι του θα μπορούσαν επίσης να κυκλοφορούν σε γαϊδούρια από την Τουρκία.
