Abstract

Cilj je studije bio odrediti otpornost kokcidija na jonofore rabljene na farmama tovnih pilića u provinciji Tizi-Ouzou. Prikupljen je izmet i pronađeni izolati Eimeria oociste su analizirane morfometrijom da bi se odredio njihov sastav te su njima per os cijepljeni pilići Arbor Acres soja, uzgojeni na zemlji. Četiri od šest skupina tih pilića podvrgnuto je ispitivanjem osjetljivosti oocista na četiri antikokcidika dodanih njihovoj hrani [(robenidin (33 ppm), monenzin (120 ppm), narazin-nikarbazin (80 ppm) i salinomicin (60 ppm)], druge dvije skupine bile su kontrolne. Rezultati studije otkrili su prisutnost potpune otpornosti na monenzin i robenidin, kao i djelomičnu otpornost na salinomicin i kombinaciju narazin-nikarbazin. Izostanak osjetljivosti na monenzin i robenidin nije bio iznenađujući obzirom na njihovu neprikladnu i nerazumnu dugogodišnju uporabu kao jedine antikokcidne tvari. Pojava djelomične otpornosti na narazin-nikarbazin i salinomicin ukazuje na postojanje razvoja unakrsne otpornosti u populaciji Eimeria. Mogućnost relativno ujednačenog sastava Eimeria vrste prikupljene na ovim farmama upućuje na to da Eimeria acervulina i Eimeria maxima brže razvijaju otpornost na rabljene jonofore. Zaključno, potrebno je rigorozno razviti strategiju kontrole razmatrajući druge molekule koje su alternativne antikokcidicima.
