The presence of American liver fluke (Fascioloides magna) in Croatian wild ruminant species was detected for the first time in January 2000. At the same time, the problem of adequate parasitological monitoring and treatment appeared in the captive deer population. Quarantine and health screening protocols, as well as migration and transportation influence(More)
A naturally occurring outbreak of fasciolosis in a group of 20 Merinolandschaf (German Merino) sheep was studied. Hematological and blood biochemical values in sheep spontaneously infected with liver fluke Fasciola hepatica were compared with equivalent values in 20 parasite-free sheep from organically farmed flock. Investigated animals were kept in outdoor(More)
Serum samples from 52 free-ranging brown bears (Ursus arctos) collected in Croatia over a period of 10 yr (1998-2007) were tested by microscopic agglutination test for specific antibodies (Ab) to 12 Leptospira spp. pathogenic serovars. At titers ranging from 1:100 to 1:2,000, 19 samples (36.5%) were Abpositive to at least one serovar. Antibodies for 10(More)
Over a period of fi ve years (2002-2007) a total of 351 wild boar (Sus scrofa) serum samples were collected during regular hunting procedures. All samples were tested by microscopic agglutination test (MAT) for the presence of specifi c antibodies (AB) to 12 Leptospira spp. serovars. At different sera dilutions (ranging from 100 to 3200) 112 samples (31.9%)(More)
Trichotecene poisoning in poultry can cause oral lesions, haemorrhages, depletion and necrosis in the lymphopoetic organs and death. Spontaneous poisonings with these toxins are rarely described. This paper describes the spontaneous poisoning of two Brahma chickens with T-2 toxin, diacetoxyscirpenol and deoxynivalenol. Two out of 10 chickens died under(More)
Neoplastic diseases are among the leading health concerns in medicine. As such, epidemiological studies considering canine tumours are benefi cial in understanding the patterns of tumour occurrence. The aim of this study was to analyze data on the occurrence of canine tumours in Croatia. a total of 1568 tumours were diagnosed after routine biopsy submission(More)

Certain indicators of hare population dynamics (Lepus europaeus Pallas, 1778) were analyzed during the 2004/2005 hunting season in 5 hunting grounds of northwestern Croatia. Selected areas included both lowland and mountain habitats. In that period 279 eyes were collected following the regular hunting operations for the purpose of age determination(More)
BACKGROUND Testicular tumors are the most common genital neoplasms in male dogs, with Leydig cell tumors (LCT), seminomas (SEM), and Sertoli cell tumors (SCT) the most common forms. Human SEM are classified as classical (CSEM) or spermatocytic (SSEM). Intratubular germ cell neoplasia of undifferentiated origin (IGCNU) is another form of human testicular(More)
The effects of caponisation on live weight, weight gain, carcass characteristics and blood plasma values of pheasants were examined. Eighty pheasants reared in feathered game nurserie were included in experiment. The birds were castrated at 8 or 12 weeks of age. The age of castration up to 12 weeks showed complete testicular regeneration while when(More)
