Hyalomma marginatum and rufipes are two-host tick species, which mainly distributed in southern Europe, Africa middle-eastern Asia. They well-known vectors of Crimean Congo hemorrhagic fever (CCHF) virus other viruses as well Rickettsia aeschlimannii. In recent years, these species have been found sporadically Germany, but they do not belong to the autochthonous fauna Germany.Ticks with unusual morphology were collected sent from private persons or public health offices involve institutions...
Infections with liver and rumen flukes are among the most frequent parasitic diseases in cattle worldwide. In Europe, predominant fluke species is Fasciola hepatica, recently rapidly spreading mostly Calicophoron daubneyi occasionally Paramphistomum leydeni. this study, 1638 faecal samples from individual dairy cows 24 northern 18 southern German farms as well one central farm, all preselected for potential F. hepatica infection, were examined to determine in-herd prevalences of infections....
Ixodes ricinus constitutes the main European vector tick for Lyme borreliosis pathogen Borrelia burgdorferi (sensu lato), relapsing fever borrelia miyamotoi, as well Anaplasma phagocytophilum and several Rickettsia species. Under laboratory conditions, a transovarial transmission to next generation is described spp. spp., especially regarding B. whereas efficiency of transfer under field conditions largely unstudied.In order better estimate potential infection risk by larvae humans animals,...
In Europe, two tick species of the genus Dermacentor occur, marginatus and reticulatus. When spatial distribution both in Germany was studied comprehensively for first time 1976, D. populations were recorded along Rhine Main river valleys southwestern Germany, while reticulatus very rare. last 50 years, however, a considerable range expansion has been noted several European countries. To assess current spp. citizens asked to send ticks suspected belong or that "unusual" appearance. From...
Ticks and tick-borne diseases play a major role in companion animal health. Additionally, the European tick fauna is changing, for instance due to spread of Dermacentor reticulatus, displaying higher likelihood winter activity than Ixodes ricinus. Therefore, we investigated current infestations dogs cats Germany parts Austria seasonal infestation risk.Overall, 219 veterinary practices were invited collect ticks from on monthly basis. morphologically identified female I. ricinus specimens...
The newly discovered group of Jingmenviruses has been shown to infect a wide range hosts and associated with febrile illness in humans. During survey for ticks from Lower Saxony, Germany, Alongshan virus (ALSV) was identified Ixodes spp. ticks. Additional screenings revealed the presence ALSV bodies saliva collected at several locations Saxony. Vector competence studies that included ricinus Dermacentor reticulatus validated replication within those tick species. In vitro feeding experiments...
Changing climatic conditions and other anthropogenic influences have altered tick distribution, abundance seasonal activity over the last decades. In Germany, two most important species are Ixodes ricinus Dermacentor reticulatus, latter of which has expanded its range across country during past three While I. was rarely found colder months in past, D. reticulatus is known to be active at lower temperatures. To quantify appearance winter, specimens were monitored quasi-natural plots times a...

Abstract Background Hyalomma marginatum and H. rufipes are two-host tick species, which mainly distributed in southern Europe, Africa to central Asia but may also be found Central Northern Europe through introduction by migratory birds. Methods Ticks were collected while feeding or crawling on animals humans, from the environment, different regions Germany, between 2019 2021 a citizen science study 2022 2023 wake of this study. Results From 2023, total 212 adult ticks detected Germany. This...
Myiasis due to parasitic fly larvae (maggots) can have major consequences for animal health and welfare. The European hedgehog Erinaceus europaeus is frequently presented in rehabilitation centres veterinary practices problems, including myiasis. In the present study, 557 hedgehogs at wildlife Northern Germany during 2018–2021 were examined presence of dipteran eggs larvae. Overall, 15.6% animals carried and/or Four different species identified by PCR sequencing internal transcribed spacer 2...
The present study investigated the prevalence of Borrelia burgdorferi sensu lato (s.l.) genospecies in Ixodes ricinus ticks collected Hanover, Northern Germany, 2010. At same time served as fifth-year-follow-up for data comparison with 2005.A total 2100 questing were and analysed by quantitative real-time PCR (qPCR) subsequent species differentiation via Reverse Line Blot Sanger sequencing. Simultaneously, results obtained 2010 compared to infection rates from 2005 evaluate development B....
Malaria represents a major cause of death from infectious disease. Hemozoin is Plasmodium-derived product that contributes to progression cerebral malaria. However, there gap knowledge regarding how hemozoin recognized by innate immunity. Myeloid C-type lectin receptors (CLRs) encompass family carbohydrate-binding act as pattern recognition in In the present study, we identify CLR CLEC12A receptor for hemozoin. Dendritic cell-T cell co-culture assays indicate CLEC12A/hemozoin interaction...
Abstract Background The poultry red mite (PRM) Dermanyssus gallinae is the most common ectoparasite on and causes high economic losses in farming worldwide. Pyrethroid acaricides have been widely used for its control and, consequently, pyrethroid resistance has arisen. In this study we aim to investigate occurrence of geographical distribution mutations across PRM populations Europe. Results Full dose–response contact bioassays revealed very levels against several pyrethroids...
A considerable range expansion of Dermacentor reticulatus has been observed in several European countries, which is concerning the light its vector function for pathogens, including Babesia canis and tick-borne encephalitis virus (TBEV). The present study provides an update on distribution ticks Germany, using a citizen science approach. Ticks were collected by citizens from March 2020 to May 2021, submitted along with information date location collection, potential hosts details about...
