the celtic fringe of britain: insights from small mammal phylogeography.recent genetic studies have challenged the traditional view that the ancestors of british celtic people spread from central europe during the iron age and have suggested a much earlier origin for them as part of the human recolonization of britain at the end of the last glaciation. here we propose that small mammals provide an analogue to help resolve this controversy. previous studies have shown that common shrews (sorex araneus) with particular chromosomal characteristics and water voles (arvi ...200919793757
cornea, retina, and lens morphology in five soricidae species (soricomorpha: mammalia).we analyzed the cornea, retina, and lens of five species of soricidae (pygmy shrew, sorex minutus; common shrew, sorex araneus; millet's shrew, sorex coronatus; water shrew, neomys fodiens; greater white-toothed shrew, crocidura russula) by light and electron microscopy. in all of these species, the corneal epithelium showed a dead cell layer, which may increase the refractive power of the cornea, thereby reducing the hypermetropy that would be expected in a small eye. moreover, the anterior sur ...200919367448
relationships of basal metabolic rate, relative testis size and cycle length of spermatogenesis in shrews (mammalia, soricidae).the aim of the present study was to determinate the cycle length of spermatogenesis in three species of shrew, suncus murinus, sorex coronatus and sorex minutus, and to assess the relative influence of variation in basal metabolic rate (bmr) and mating system (level of sperm competition) on the observed rate of spermatogenesis, including data of shrew species studied before (sorex araneus, crocidura russula and neomys fodiens). the dynamics of sperm production were determined by tracing 5-bromod ...200818402763
metals distribution and interactions in tissues of shrews (sorex spp.) from copper- and zinc-contaminated areas in poland.to assess the risk from heavy metal accumulation to insectivorous species exposed to different pollutants, shrews [sorex araneus (linnaeus 1758) and sorex minutus (linnaeus 1766)] were collected in the olkuski ore region (oor; a zn and cd smelter area), legnicko-głogowski copper mine region (lgcr; a copper ore-mining area), and białowieza forest (bf; a control area). a few sites were chosen in each region and a total of 57 animals were collected from them. the liver and kidneys were dissected fr ...200516091604

co-circulation of soricid- and talpid-borne hantaviruses in poland.previously, we reported the discovery of a genetically distinct hantavirus, designated boginia virus (bogv), in the eurasian water shrew (neomys fodiens), as well as the detection of seewis virus (swsv) in the eurasian common shrew (sorex araneus), in central poland. in this expanded study of 133 shrews and 69 moles captured during 2010-2013 in central and southeastern poland, we demonstrate the co-circulation of bogv in the eurasian water shrew and swsv in the eurasian common shrew, eurasian py ...201425445646
a novel myxozoan parasite of terrestrial mammals: description of soricimyxum minuti sp. n. (myxosporea) in pygmy shrew sorex minutus from hungary.as part of a biodiversity study in northwestern hungary, we conducted a parasitological survey of small mammals. in both common shrews (sorex araneus linnaeus) and pygmy shrews (sorex minutus linnaeus), we found myxospores of a species of soricimyxum prunescu, prunescu, pucek et lom, 2007 (myxosporea) and plasmodia in the bile ducts within the liver. spores from both species of shrewswere morphologically and morphometrically indistinguishable, but differed in their ssu rrna gene sequences by 3.3 ...201526370293
a synopsis of records of myxozoan parasites (cnidaria: myxozoa) from shrews, with additional data on soricimyxum fegati from common shrew sorex araneus in hungary and pygmy shrew sorex minutus in slovakia.myxozoans (cnidaria: myxozoa) are almost exclusively endoparasites of aquatic vertebrates and invertebrates, with the notable exception being two species of soricimyxum prunescu, prunescu, pucek et lom, 2007 described from terrestrial shrews (soricidae) in central europe. myxospores of the two parasites are morphologically indistinguishable, but have ssu rdna sequences that differ by about 4%. herein, we report additional molecular and histology data from soricimyxum fegati prunescu, prunescu, p ...201627312127
the generalist tick ixodes ricinus and the specialist tick ixodes trianguliceps on shrews and rodents in a northern forest ecosystem--a role of body size even among small hosts.understanding aggregation of ticks on hosts and attachment of life stages to different host species, are central components for understanding tick-borne disease epidemiology. the generalist tick, ixodes ricinus, is a well-known vector of lyme borrelioses, while the specialist tick, ixodes trianguliceps, feeding only on small mammals, may play a role in maintaining infection levels in hosts. in a northern forest in norway, we aimed to quantify the role of different small mammal species in feeding ...201526671686
investigation of the ecology of francisella tularensis during an inter-epizootic period.abstract a 1-year study of the ecological cycle of francisella tularensis was performed in an enzootic area during an inter-epizootic period. the study was based on multiple sampling of all major constituents of the disease cycle. seroprevalence of tularemia in the european brown hare (lepus europaeus) population was 5.1% (10/197) with low antibody titers (1/10 and 1/20), and f. tularensis ssp. holarctica was isolated from four hares. f. tularensis was not detected in the 38 common voles (microt ...201021142970
seewis virus: phylogeography of a shrew-borne hantavirus in siberia, russia.hantaviral antigens were originally reported more than 20 years ago in tissues of the eurasian common shrew (sorex araneus), captured in european and siberian russia. the recent discovery of seewis virus (swsv) in this soricid species in switzerland provided an opportunity to investigate its genetic diversity and geographic distribution in russia.201020426688
new method for visualization of c-heterochromatin in synaptonemal complex spreads.dapi staining of the metaphase chromosomes pretreated with barium hydroxide generates a c-like banding pattern. in this work a protocol for visualizing similar pattern at the synaptonemal complex (sc) spreads after immunostaining is suggested. this method was used to visualize centromeric and sex heterochromatin at the sc spreads of guppy fish (poecilia reticulata peters, 1859). the efficiency of this method was further confirmed at sc spreads of the northern red-backed vole (myodes rutilus (pal ...201324260695

apparent scarcity of glial fibrillary acidic protein expression in the brain of the pygmy shrew sorex minutus as revealed by immunocytochemistry.we examined astroglial cells in the brain of the pygmy shrew sorex minutus (insectivora). for that purpose we labeled glial fibrillary acidic protein (gfap) immunohistochemically in brain sections with a polyclonal antibody. antigen retrieval experiments were performed to counteract formaldehyde fixation masking of gfap epitopes. our results showed remarkable paucity of gfap-immunoreactive cells and fibers in the cerebral cortex and nuclei, as well as in the majority of the diencephalic and mese ...200415351450
new records for anaplasma phagocytophilum infection in small mammal species.tick-borne diseases pose a major threat in public health. the epidemiological dynamics of these diseases depends on the tick vector species and their hosts, as well as the geographical distribution and ecology of both. among many possible hosts for ticks, small mammals have a major role in the development of immature stages of several tick species. small mammals are also important reservoir hosts for several pathogenic agents and possible reservoirs for anaplasma phagocytophilum. in this context ...201829558990
molecular evidence and diversity of the spotted-fever group rickettsia spp. in small mammals from natural, suburban and urban areas of eastern slovakia.rickettsiae of the spotted fever group are considered as emerging pathogens; ticks, fleas and mites are known to be their vectors. however, the prevalence and species diversity of rickettsiae in small mammals and the role of these hosts in the circulation of bacteria are much less studied. during 2014-2016, a total of 250 small mammals (apodemus agrarius, apodemus flavicollis, apodemus uralensis, myodes glareolus, crocidura leucodon, crocidura suaveolens, micromys minutus, microtus arvalis, micr ...201830207272
detection of rickettsia spp. in fleas collected from small mammals in slovakia, central europe.this survey is aimed at investigation of species composition of fleas removed from small terrestrial mammals captured in rural, suburban, and urban types of habitat and molecular screening of the presence and diversity of rickettsia species in collected ectoparasites. in total, 279 fleas (siphonaptera) belonging to 9 species of 2 families, ceratophyllidae and hystrichopsyllidae, were collected from 115 (46%) out of 250 trapped small mammals of eight species (apodemus agrarius, apodemus flavicoll ...202032366189
how did pygmy shrews colonize ireland? clues from a phylogenetic analysis of mitochondrial cytochrome b sequences.there is a long-standing debate as to how ireland attained its present fauna; we help to inform this debate with a molecular study of one species. a 1110 base pair fragment of the mitochondrial cytochrome b gene was sequenced in 74 specimens of the pygmy shrew, sorex minutus, collected from throughout its western palaearctic range. phylogenetic analysis of these sequences revealed several well-supported lineages. most of the 65 haplotypes belonged to a northern lineage, which ranged from britain ...200312908980
detection of shrew-borne hantavirus in eurasian pygmy shrew (sorex minutus) in central europe.recently, it was found that not only rodents but also shrews are reservoir hosts of hantaviruses. in central europe, only seewis virus, associated with the eurasian common shrew (sorex araneus), has been recognized until now. in the present report, tissue samples from shrews belonging to crocidurinae and soricinae subfamilies, trapped in czech republic, germany, and slovakia, were screened for the presence of novel hantaviruses. three new hantavirus partial l-segment sequences were obtained from ...201323602837
