We focused on a comparison of karyological data for the European brown hare Lepus europaeus, from the Asian part of Turkey. In Turkish L. europaeus, the diploid number (2n), the fundamental number of chromosomal arms (FN) and the number of autosomal arms (FNa) were determined to be 2n=48, 84 and 80, respectively. The autosomes are composed of three pairs of metacentric chromosomes, four pairs of submetacentric chromosomes, ten pairs of subtelocentric chromosomes and six pairs of acrocentric chromosomes. The X chromosome was a medium-large submetacentric and the Y chromosome was a very small acrocentric. This is the third report for L. europaeus from Turkey and confirmed the previous results with regard to 2n. However, when comparing our findings with those of other authors, there were karyotypic differences among the chromosomes. These differences were related to the number of chromosome arms. Additionally, we present the skull measurements of seven samples for the Turkish brown hare collected from three localities, and these measurements conformed to those of previous studies.

The present study was focused on both the new distributional records and karyological data for Arvicola amphibius from the European part of Turkey. The karyotype of the Eurasian water vole was investigated by examining its metaphase chromosomes. The diploid number of chromosomes (2n), the fundamental number of chromosomal arms (FN) and the number of autosomal arms (FNa) were found to be 36, 64 and 60, respectively, for one female individual from a single locality in the European part of Turkey. It was determined that A. amphibius has 2n = 36 chromosomes, consisting of seven metacentric, three submetacentric, three subtelocentric and four acrocentric chromosome pairs. The X chromosome was a large submetacentric. The present study confirmed the previous results with regard to 2n. However, comparison of our findings with those of other authors indicates that there are karyotypic differences among the chromosomes. These differences were related to the morphology of chromosomes. Additionally, we reported external and skull measurements and new distributional records from six localities for the Turkish water vole. The measurements presented in this study conform to those of samples examined by other authors.

Liver lesions were studied in 40 free-living adult European brown hares ( Lepus europaeus) and varying hares ( Lepus timidus) of both sexes that had died in Sweden with the viral infection European brown hare syndrome (EBHS). The lesions were characterized by their histopathologic, immunohistochemical, and electron microscopic findings. Periportal to massive coagulation necrosis was a distinctive feature of EBHS. Lytic necrosis, inflammation, fatty degeneration, and cholangitis occurred variably. Accumulation of basophilic granules in the cytoplasm of hepatocytes was commonly observed; these lesions corresponded ultrastructurally to mitochondrial calcification. Viral antigen was revealed in the cytoplasm and nucleus of hepatocytes and in the cytoplasm of macrophages.

AbstractFascioliasis has recently been included in the WHO list of Neglected Zoonotic Diseases. Besides being a major veterinary health problem, fascioliasis has large underdeveloping effects on the human communities affected. Though scarcely considered in fascioliasis epidemiology, it is well recognized that both native and introduced wildlife species may play a significant role as reservoirs of the disease. The objectives are to study the morphological characteristics of Fasciola hepatica adults and eggs in a population of Lepus europaeus, to assess liver fluke prevalence, and to analyze the potential reservoir role of the European brown hare in northern Patagonia, Argentina, where fascioliasis is endemic. Measures of F. hepatica found in L. europaeus from northern Patagonia demonstrate that the liver fluke is able to fully develop in wild hares and to shed normal eggs through their faeces. Egg shedding to the environment is close to the lower limit obtained for pigs, a domestic animal whose epidemiological importance in endemic areas has already been highlighted. The former, combined with the high prevalence found (14.28%), suggest an even more important role in the transmission cycle than previously considered. The results obtained do not only remark the extraordinary plasticity and adaptability of this trematode species to different host species, but also highlight the role of the European brown hare, and other NIS, as reservoirs capable for parasite spillback to domestic and native cycle, representing a potentially important, but hitherto neglected, cause of disease emergence.
