Abstract

Bolest kljuna i perja papiga predstavlja jednu od najvažnijih bolesti kako u ptica
u divljini tako i kod ptica u zatočeništvu. Uzrokuje promjene na perju, kljunu i
kandžama, iako može biti smrtonosna, pogotovo u mladih ptica, dok kod starijih
uzrokuje kronični oblik bolesti koji uvelike smanjuje kvalitetu života ptici. Uzrokovana
je cirkovirusom koji je imunosupresivan i hepatotoksičan, što posljedično vodi do
razvoja sekundarnih infekcija i uginuća. Bolest je proširena po cijelom svijetu
zahvaljujući izrazitoj kontagioznosti virusa. Cilj ovog istraživanja bio je odrediti
pojavnost cirkovirusa kod papiga u zatočeništvu u Hrvatskoj analizirajući uzorke
zaprimljene u Ambulanti za ptice Veterinarskog fakulteta Sveučilišta u Zagrebu i
prikupljene iz jedne uzgajivačnice ptica. Sakupljen je ukupno 131 uzorak podrijetlom
od različitih vrsta papiga - 20 uzoraka izmeta, 24 uzorka perja, 9 uzoraka organa i 2
brisa kloake (=55) iz Ambulante, dok je u uzgajivačnici prikupljeno 40 uzoraka izmeta
i 36 uzoraka perja (=76). Utvrdili smo pozitivan rezultat u 16 od 36 (44,4%) pregledanih
jedinki iz Ambulante. Polovica pozitivnih jedinki nije pokazivala nikakve kliničke
znakove koji bi upućivali na infekciju cirkovirusom. Zanimljiv podatak je da smo u
uzgajivačnici utvrdili pozitivan rezultat u 5 od 54 (9,26%) pregledanih jedinki, te je
svih pet jedinki držano u paru s pticom koje su pokazale negativan rezultat. S obzirom
na dobivene rezultate, preporuča se uvođenje mjera za kontinuirano praćenje i
regulaciju pojavnosti cirkovirusa u Hrvatskoj, s naglaskom na monitoring
uzgajivačnica i trgovina kućnim ljubimcima.

Abstract (english)

Psittacine beak and feather disease represents one of the most important diseases in
wild birds, as well as in pet birds. It affects feathers, beaks and claws of the birds, although it
is often a fatal disease, especially in young birds, while in adult birds it can cause chronic
problems which significantly diminishes the quality of life in the infected birds. It is caused by
circovirus that is immunosuppressive and hepatotoxic, which consequently leads to secondary
infections and death. The disease is distributed all around the world thanks to its high
contagiousness. The purpose of this study was to determine the prevalence of circovirus in
parrots in captivity through analyzing samples obtained from the Bird Clinic at the Faculty of
Veterinary Medicine, University of Zagreb, and from a parrot breeder. We have collected 131
sample originating from various psittacine species – 20 fecal samples, 24 feather samples, 2
cloacal swabs and 9 organ samples (=55) were collected form the Clinic, while 40 fecal samples
and 36 feather samples (=76) were collected from the breeder. We have determined that 16 out
of 36 (44,4%) examined birds from the Clinic tested positive for PBFD. Half of the positive
birds did not show any clinical signs of PBFD. Interestingly, we have determined 5 out of 54
(9,26%) positive birds from the breeder, and all positive birds were paired with birds which
tested negative for PBFD. Considering the results of this research, it would be beneficial to
introduce regulatory measures for continuous monitoring of circovirus presence and
transmission in Croatia, with emphasis on breeders and pet shops.
