Fascioloidosis is a parasitic disease of primary wild and domestic ruminants, caused by giant liver fluke, Fascioloides magna. The definitive host of the liver fluke in its area of origin (North America) is the white-tailed deer (Odocoileus virginianus). In Europe, the red deer (Cervus elaphus) and European fallow deer (Dama dama) are definitive hosts and the most sensitive hosts to F. magna infection, on which the parasite exerts serious pathogenic effects. In this study, we analyzed fecal samples and livers of 72 D. dama from 11 hunting grounds in Arad County, Romania. Of the 72 fecal samples and livers from D. dama, trematodes of the genus Fascioloides were identified in four (5.56%). Sequencing revealed that the trematodes identified in the samples were similar to the sequence of F. magna (GenBank no. EF534992.1, DQ683545.1, KU232369.1). The sequence obtained from the molecular analysis has been deposited in GenBank® under accession number OQ689976.1. This study describes the first report of giant liver fluke (F. magna) infection in D. dama in Romania.

Due to its adaptive versatility to numerous types of habitats, extremely diverse both in terms of composition and specificity, developed in various areas of the Western Plains of Romania, the European fallow deer (Dama dama) is a species with high ecological plasticity. In this area, the D. dama interacts with other species of wild fauna but also with numerous domestic animals, an important aspect in terms of the sanitary-veterinary status of animal populations, as well as the existence of a potential risk of infection with various species of parasites that can cause the D. dama specimens to obtain certain diseases and even zoonoses. A total of 133 esophagi from D. dama have been examined for helminths. Of the 133 esophagus samples from D. dama, nematodes of the genus Gongylonema were identified in 25 (18.80%). Sequencing revealed that the nematode identified in the samples was 99% similar to the sequence of Gongylonema pulchrum (GenBank no. LC026018.1, LC388754.1, AB646061). The present research is the first report of the nematode G. pulchrum from D. dama in Romania.

Demodicosis is one of the most important external parasitic diseases found in carnivores. Three species of the Demodex mite inhabit the skin of dogs and related species, D. canis being the most prevalent. This paper describes the first case of infestation with D. injai in a golden jackal in Romania. An emaciated golden jackal female body found in Timiș County, western Romania, was examined at Parasitology Department of Faculty of Veterinary Medicine, Timișoara. The gross lesions were present on different regions of the body: feet, tail, axillary and inguinal areas, and skin folds as well, consisting of erythema, extensive severe alopecia with lichenification, seborrhea, and scaling. In order to establish diagnosis, microscopic examination of skin scrapes, trichogram (hair plucking), acetate tape test (impression), fungal culture, and PCR were performed. Both microscopic measurements and PCR analysis have confirmed the presence of D. injai.
