Grey seals (Halichoerus gryphus), the main final host of gastric parasitic nematode Contracaecum osculatum in Baltic, have recently recolonized southwestern Baltic Sea. This colonization could lead to an increase prevalence and intensity third-stage larvae C. livers cod (Gadus morhua), which serve as transport for this helminth. We performed a parasitologic study spring 2012 compared results with previously unpublished data from 1982/1983. Additionally, grey were counted annually 2000 2011...
Freshwater pulmonate snails from three locations in Lake Furesø north of Copenhagen were screened for infection with furcocercariae (by shedding the laboratory) and recovered parasite larvae diagnosed by molecular methods performing PCR rDNA sequencing internal transcribed spacer [ITS] region). Overall prevalence was 2%. Recovered cercariae Lymnaea stagnalis (Linnaeus) as Diplostomum pseudospathaceum Niewiadomska, 1984 (prevalence 4%) Radix balthica D. mergi (Dubois, 1932) 2%). Pathogen-free...
We report the results of investigations 2010 through 2023 hymenopteran parasitoids associated with gall midges in Europe. A total 242 collections were made, from each which one to several parasitoid species emerged, resulting ca. 200 recorded and 267 host-parasitoid interaction records. The families involved Eulophidae (63 species), Platygastridae (56 Torymidae (34 Pteromalidae (31 Ceraphronidae (5 Eupelmidae (4 Eurytomidae (2 species) Encyrtidae (1 species). As many as 159 interactions are...
Inflammatory bowel disease (IBD) in developed countries is linked with elevated hygienic standards. One of the several factors involved this question may be reduced exposure to immunomodulatory effects parasitic helminths. Several investigations on treatment mice and humans helminth-derived substances have supported notion, but underlying mechanisms remain unclear. This study therefore dissects what extent a series immune-related genes are modulated zebrafish experimentally induced colitis...
Crohn's disease and ulcerative colitis—inflammatory bowel diseases (IBD)—are chronic conditions with an inadequately understood pathogenesis. Employing a set of novel molecular markers in gene expression assay (qPCR), we have used adult zebrafish to investigate two acute inflammatory models, induced by the haptenizing agents oxazolone TNBS. In addition, goblet cell dynamics scales intestine 5-HT (serotonin) intestinal tissues were investigated through optical projection tomography. Gene...
An updated list of terrestrial Parasitengona mites Denmark, containing 34 species aggregated in eight families, is presented and compared to existing records from Fennoscandia. Five parasitengone species, Charletonia cardinalis, Leptus mariae (Erythraeidae), Platytrombidium fasciatum (Microtrombidiidae), Paratrombium egregium (Trombidiidae) Centrothrombidium blackwellae (Johnstonianidae) are recorded as new the fauna Denmark. We provide 29 parasite-host association between their arthropod...
The paper presents descriptions of new taxa and records quill mites the family Syringophilidae Lavoipierre, 1953 (Acari: Prostigmata: Cheyletoidea) parasitising aquatic birds in Faroe Islands, Denmark. Sulisyringophilus jenskjeldi n. gen., sp., is described from northern gannet, Morus bassanus (Linnaeus) (Suliformes: Sulidae). genus, Sulisyringophilus, genus differs morphologically similar Procellariisyringophilus Schmidt Skoracki, 2007 by presence lateral hypostomal teeth leg setae vsII...
A new species of nasal mite, Ptilonyssus simplex n. sp. is described and illustrated based on material from Bohemian waxwing, Bombycilla garrulus (Linnaeus, 1758) (Bombycillidae). The bird host was collected in a residental area Hirtshals, Denmark, October 2022. set diagnostic characters presented order to differentiate the overall similar bombycillae Pence, 1973 which has been recorded spp. Europe Northern America.
A new feather mite species, Temnalges fulicae sp. n. (Psoroptoididae: Pandalurinae), is described from two species of coots, Fulica americana Gmelin, 1789 (type host), in Canada, and F. atra Linnaeus, 1758, Denmark. The close to other the genus associated with rails (Rallidae), especially T. megalonyx Gaud, 1968, having a long spur-like process on tibia III males, prodorsal hysteronotal shields separated by wide area striated tegument females. Males are most clearly distinguished opisthosoma...
Fungal and arthropod consumers constitute the vast majority of global terrestrial biodiversity. Yet, link from richness composition producer (plant) communities to consumer is poorly understood. species could be a simple function at site. Alternatively, it complex chemical structural properties making up communities. We used databases on plant–fungus plant–arthropod trophic links derive biota per associated plant (coined score). assessed how well scores predicted by attributes species. Next,...
Abstract Consumers constitute the vast majority of global terrestrial biodiversity. Yet, local consumer richness is poorly understood. Plant species offers a simple hypothesis to how diversification carbon substrates may promote diversity arthropods and fungi. We took this one step further used databases on plant-consumer interaction links derive associated biota per plant (link score). Using inventory 130 sites we investigated 1) well link score could be predicted by attributes 2) if sum...
Aprostocetus eriophyes (Taylor, 1909) (Hymenoptera: Eulophidae) is reported as new to the Hungarian fauna. Female specimens were reared from galls of hazelnut big bud mite (Phytoptus avellanae Nalepa, 1889) (Phytoptidae) collected in February April 2017 at six different locations Hungary. Diagnosis, hosts, biology and distribution A. discussed. With 3 figures.
