Περίληψη

Ο Αφθώδης πυρετός είναι υψηλής μεταδοτικότητας νόσος των δίχηλων ζώων, η οποία προκάλεσε μεγάλες ζημιές οτο ζωικό κεφάλαιο του Νομού Έβρου. Από το 1994 μέχρι το 2000 υπήρξαν κρούσματα αφθώδη τα έτη 1994,1996 και 2000. Συγκεκριμένα, το 1994 θανατώθηκαν 22 βοοειδή και 375 αιγοπρόβατα, το 1996 6.250 βοοειδή, 24.261 αιγοπρόβατα και 647 χοίροι και το 2000 5.383 βοοειδή, 4.405 αιγοπρόβατα και 359 χοίροι. Οι επιζωοτίες των ετών 1994, 1996 και 2000 ελέγχθηκαν με την ευθανασία των ζώων των μολυσμένων κοπαδιών και την προληπτική ευθανασία των ζώων, τα οποία βρίσκονταν σε εκτροφές οιοποίες χαρακτηρίστηκαν λοιμυποπτες. Το 1994 και 1996 απομονώθηκε ιός τύπου Ο και το 2000 ιός τύπου ASLAj. Στην επιζωοτία του 2000 το στέλεχος τύπου ASIAj μόλυνε κυρίως τα βοοειδή, τα οποία παρουσίασαν μεγάλη ευαισθησία και έντονα κλινικά συμπτώματα.Τα πρόβατα και τα κατσίκια δεν έδειξαν ευαισθησία στον ιό και κλινικά συμπτώματα εμφάνισαν τα ζώα δυο κοπαδιών προβάτων, ενός κοπαδιού κατσικιών και μίας εκτροφής χοίρων. Τα κοπάδια αυτά ήταν τα μόνα που μολύνθηκαν. Το 2000 συνέβη η μοναδική περίπτωση μόλυνσης χοίρων με ιό τύπου ASLAj. Τα περιοριστικά μέτρα ίσχυσαν πέντε μήνες. Σε αυτήν τη μελέτη περιγράφεται η συμπτωματολογία και τα μέτρα ελέγχου, που απορρέουν από την εμπειρία αυτών των ετών. Δίνονται, επίσης, στατιστικά στοιχεία των κρουσμάτων της νόσου και φωτογραφικό υλικό.
