Abstract

Oko 1500 vrsta trakavica parazitira u ribama i neke mogu uzrokovati značajne bolesti.
Među njima treba izdvojiti trakavice roda Triaenophorus i to vrste T. nodulosus i T. crassus,
koje uzrokuju trienoforozu štuke. U crijevu konačnog domaćina, tj. ribi iz porodice Esocidae,
ove odrasle trakavice uzrokuju erozije i ulceracije sluznice praćene staničnom infiltracijom i
fibrozom. Budući da je štuka (E. lucius i E. masquinongy) jedini konačni domaćin trakavice i
da protiv trienoforoze u Republici Hrvatskoj nema registriranog lijeka, smanjenje populacije
štuke u otvorenim vodama, smanjit će učestalost i intenzitet bolesti. U diplomskom radu,
histološkom pretragom crijeva štuke invadirane odraslim trakavicama T. nodulosus, istražena
je patogenost parazita za konačnog domaćina. Materijal za istraživanje porijeklom je iz rijeke
Mrežnice i prikupljen je tijekom 2021. godine u sklopu provedbe projekta Hrvatske zaklade za
znanost („Biomolekule koje vežu metale i zdravstveni poremećaji kod slatkovodnih
organizama izloženih industrijskom otpadu“; šifra projekta IP-2019-04-2636, voditeljica

Abstract (english)

About 1500 tapeworms (Cestoda) parasitise fish, and some of them may cause
important diseases. Among them are cestodes of the genus Triaenophorus, specifically T.
nodulosus and T. crassus, which cause triaenophorosis in pikes (Esox sp.). In northern pike (E.
lucius), their definitive host, these adult tapeworms cause intestinal ulceration with cellular
infiltration and fibrosis. Since in Croatia the northern pike is the only definitive host and there
are no legally approved anthelmintics, the only strategy to control triaenophorosis in natural
waters is to reduce the population of northern pike. In the present study, the pathogenic effect
of adult T. nodulosus was assessed by histological examination. The material (infected fish)
was collected in 2021 at the Mrežnica River. The study was carried out as part of the Croatian
Science Foundation-supported project Metal-binding biomolecules and health disturbances of
freshwater organisms exposed to industrial wastes (IP-2019-04-2636).
