Climate change associated transformations of Arctic marine ecosystems are having detrimental impacts on Arctic endemic marine mammals. However, warming conditions are providing new habitats for temperate marine mammals, some of which are expanding into Arctic regions, posing a threat of novel pathogen introduction and disease transmission. We analyzed swab samples for Influenza A, morbilli‐ (Phocine distemper virus, PDV), and...

Ticks are medically relevant as vectors for multiple pathogens. Besides Ixodes ricinus , which occurs ubiquitously throughout Europe, the meadow tick Dermacentor reticulatus is increasingly common. We used a Citizen Science approach to demonstrate the recent Germany-wide range expansion of this tick species, and to investigate its infection rate with Babesia canis , a canine pathogen causing potentially fatal disease. Travelli...

Dermanyssus gallinae , the poultry red mite (PRM), is a hematophagous temporary ectoparasite that causes serious economic losses and animal health impairment on laying hen farms worldwide. Control is limited by the parasite’s hidden lifestyle, restrictions on the use of chemical acaricides and the development of resistance against certain drug classes. As a result, research was conducted to explore alternative control methods....

In the present study, the acaricidal effects of cold atmospheric pressure plasma treatment on poultry red mites of different developmental stages have been investigated under laboratory conditions using a dielectric barrier discharge system. A total of 1890 poultry red mites and 90 mite eggs, respectively, were exposed to the plasma under various parameter settings with a single plasma pulse generated using the gas mixture of...

The Northern German Black Grouse metapopulation has been affected since decades by a sharply decline that has ultimately led to a reduced genetic variability. Gastrointestinal parasitoses are common among Black Grouse, but it is not clear if they have a further negative impact on the development of this already threatened metapopulation. Therefore, between 2011 and 2014, the occurrence and seasonal variation of gastrointestina...
