Abstract

Fascioloidoza jelena lopatara je parazitska bolest uzrokovana velikim američkim
metiljem (Fascioloides magna), prvi put zabilježena u Europi blizu Torina, Italija. Parazit je u
Europu stigao preko uvezene jelenske divljači iz Sjeverne Amerike, a do sada je potvrđen u
nekoliko europskih zemalja, uključujući Hrvatsku, gdje je otkriven u istočnoj Baranji 1999.
godine. Iako parazit rijetko uzrokuje smrt kod jelenske divljači, kod drugih domaćina, poput
domaćih preživača, infekcija često završava smrću. Fascioloidoza izaziva ekonomske gubitke
zbog smanjenja kondicije, tjelesne mase i plodnosti, što zahtijeva sanitarni odstrel. Za kontrolu
fascioloidoze ključne su mjere poput praćenja prevalencije, određivanja optimalne doze
lijekova i procjene terapijske učinkovitosti. Dijagnoza se postavlja koprološkim pregledom
izmeta te pregledom jetre nakon odstrela. Područje istraživanja i utvrđivanja djelotvornosti
terapije za fascioloidozu u jelena lopatara je uzgajalište divljači XVI/8 „Kunjevci“. Tijekom
zimske prihrane divljači izvršeno je terapijsko suzbijanje fascioloidoze jelena lopatara
procijenjene brojnosti oko 180 grla. U lovnoj sezoni 2023./2024. prikupljene su 22 jetre
odstrijeljenih grla jelena lopatara. Rezultati patoanatomskih i parazitoloških pretraga jetara,
prikazani kroz tablice i grafikone pokazuju da metoda suzbijanja fascioloidoze u ograđenom
lovištu daje zadovoljavajuće rezultate, posebno kod zrelih jelena. Kontinuirano izlaganje
terapirane smjese pojačava hijerarhijsku dominaciju na hranilištima što omogućava
dominatnim jedinkama veću konzumaciju terapijske smjese. Proljetno izlaganje smjese štiti
dominantne mužjake od reinvazije. Kasno proljetno izlaganje dodatno smanjuje parazitarno
opterećenje i sprječava superinvaziju kod srednjedobnih i zrelih jelena, te pomaže u liječenju
mužjaka koji izbjegavaju zimsku prehranu. Zreli jeleni pokazali su se posebno pogodnima za
ovaj način liječenja.

Abstract (english)

Fascioloidosis in fallow deer is a parasitic disease caused by the large American liver
fluke (Fascioloides magna), first recorded in Europe near Turin, Italy. The parasite entered
Europe through imported deer from North America and has since been confirmed in several
European countries, including Croatia, where it was discovered in eastern Baranja in 1999.
While the parasite rarely causes death in deer, it often proves fatal in other hosts, such as
domestic ruminants. Fascioloidosis leads to economic losses due to reduced body condition,
weight, and fertility, necessitating culling. Key measures for controlling fascioloidosis include
monitoring prevalence, determining optimal drug dosages, and evaluating therapeutic efficacy.
Diagnosis is made through coprological examination of feces and liver inspection after culling.
The study area for assessing fascioloidosis control in fallow deer is the XVI/8 "Kunjevci" game
farm. During winter feeding, therapeutic control of fascioloidosis was carried out on an
estimated population of about 180 deer. In the 2023/2024 hunting season, 22 livers from culled
fallow deer were collected. Results of pathological and parasitological liver examinations,
presented in tables and graphs, show that the method of controlling fascioloidosis in the
enclosed hunting area yields satisfactory results, particularly in mature deer. Continuous
exposure to medicated feed increases hierarchical dominance at feeding stations, allowing
dominant individuals to consume more of the medicated feed. Spring feeding protects dominant
males from reinfection. Late spring exposure further reduces parasite load and prevents
superinfection in middle-aged and mature deer, while aiding in the treatment of males that avoid
winter feeding. Mature fallow deer have proven to be particularly well-suited for this treatment
