Abstract

Krpelji su obligatni, hematofagni ektoparaziti koji su vektori uzročnika raznih zaraznih i
parazitarnih bolesti životinja te zoonoza (virusa, bakterija, protista i oblića). U prijenosu bolesti
sudjeluju samo određene vrste krpelja šikare te njihova rasprostranjenost uvelike ovisi o
godišnjem dobu i geografskoj lokaciji. Cilj ovog istraživanja je bio identificirati vrstu, spol i
razvojni stadij krpelja te utvrditi prevalenciju krpelja šikare u Osječko-baranjskoj županiji s
obzirom na područje istraživanja i mjesece u godini. Pomoću dobivenih rezultata ustanovljena
su područja potencijalnih rizika od infekcije i invazije različitim uzročnicima bolesti koje
prenose krpelji šikare. Krpelji su uzorkovani metodom „dragging“ i „flagging“ iz okoliša, a
razvojni stadij i vrsta identificirani pomoću postojećih ključeva. Rezultati determinacije su
prikazani originalnim skicama i fotografijama, dok je prevalencija prikazana pomoću tablica i
grafikona. Uzorkovane vrste su Ixodes ricinus, Ixodes hexagonus, Haemaphysalis inermis,
Dermacentor reticulatus, Dermacentor marginatus i Rhipicephalus sanguineus. Od svih vrsta
I. ricinus je najbrojnija s prevalencijom od 43,51% (57/131). R. sanguineus čini 31,29%
(41/131) od ukupnog broja uzorkovanih krpelja te je pronađen samo u Osijeku, dok je vrsta H.
inermis pronađena jedino na Gajić planini, a čini 16,79% (22/131). Tijekom istraživanja
pronađeni su krpelji vrste D. reticulatus s prevalencijom od 6,87% (9/131) u mjestu Kopačevo,
te jedna ženka krpelja vrste D. marginatus u okolici Luga. Pronađena je i jedna nimfa vrste I.
hexagonus u okolici Josipovca. Zaključno ovom istraživanju, vrsta koja predstavlja najveći
rizik u prijenosu zaraznih i parazitarnih bolesti s obzirom na rasprostranjenost u Osječkobaranjskoj županiji je I. ricinus, no ne treba zanemariti i vektorski potencijal vrste H. inermis
sjeverno, na Gajić planini te R. sanguineus u gradu Osijeku.

Abstract (english)

Ticks are obligate, hematophagous ectoparasites which are vectors of various infectious and
parasitic animal diseases and zoonoes (viruses, bacteria, protists and helminths). Only specific
species of hard ticks are involved in disease transmission, and their distribution greatly depends
on the season and geographical location. The aim of this research was to identify the species,
gender and developmental stage of ticks and to determine the prevalence of hard ticks in
Osijek-Baranja County considering the study area and the months of the year. Using the
obtained results, areas of potential risks of infection with various tick-borne diseases agents
have been established. Ticks were sampled from the environment using the „dragging“ and
„flagging“ method, and their developmental stage and species were identified using existing
keys. The determination results are presented with original sketches and photographs, while
the prevalence is shown using tables and graphs. The species sampled were Ixodes ricinus,
Ixodes hexagonus, Haemaphysalis inermis, Dermacentor reticulatus, Dermacentor
marginatus and Rhipicephalus sanguineus. Among all species, I. ricinus is the most abundant
with a prevalence of 43,51% (57/131). R. sanguineus constitutes 31,29% (41/131) of the total
number of sampled ticks and was found only within the city of Osijek, while H. inermis was
found solely on Gajić, accounting for 16,79% (22/131). During the research, D. reticulatus
ticks were found with a prevalence of 6,87% (9/131) in the village of Kopačevo, as well as one
D. marginatus female tick in the vicinity of Lug. One I. hexagonus nymph was sampled in the
vicinity of Josipovac. In conclusion, based on this research, the species posing the highest risk
of transmission of tick borne diseases due to its distribution in the Osijek-Baranja County is I.
ricinus. However, the vector potential of H. inermis to the north on Gajić and R. sanguineus in
the city of Osijek should not be ignored.
