A serosurvey examining exposure to and tick-borne encephalitis virus in Danish blood donors, August 2022.

Objectives: (Bbsl) and tick-borne encephalitis virus (TBEV) are tick-borne pathogens. This study aimed to investigate the seroprevalence of these pathogens in Danish blood donors.

Methods: A total of 1000 plasma samples equally distributed (n = 200) from all five Danish regions were analyzed.

Can protection motivation theory predict protective behavior against ticks?

Background: Cases of reported tick-borne diseases in humans have increased over the past decades. Strategies informing the public about ticks, their associated diseases, and preventive measures are often highlighted as important in limiting pathogen transfer and disease. However, knowledge about the motivation for people to apply preventative measures is sparse.

Neoehrlichia mikurensis in Danish immunocompromised patients: a retrospective cohort study.

Background: The tick-borne bacterium, Neoehrlichia mikurensis (N. mikurensis) can cause severe febrile illness and thromboembolic complications in immunocompromised individuals. We investigated the presence of N.

Neoeherlichiosis is an emerging tick-borne infection causing disease in individuals with inadequate B-cell responses because of haematologic cancer or treatment with B-cell depletion therapies such as rituximab. The infection has recently been found as a cause of prolonged fever among several patients receiving rituximab in Denmark. This review covers current knowledge on the clinical spectrum among healthy as well as immune compromised individuals, transmission, pathogenesis, diagnosis, and treatment.

Aphid-infested beans divert ant attendance from the rosy apple aphid in apple-bean intercropping.

Ecological intensification of cropping systems aims at restoring multi-functionality while supporting current productivity levels. Intercropping is a form of ecological intensification involving ecological processes beneficial to farmers that do not take place in monocultures. Thus, it represents a practical approach to decrease the use of synthetic inputs such as insecticides in cultivated systems.

Multiple infections in questing nymphs and adult female Ixodes ricinus ticks collected in a recreational forest in Denmark.

During its lifecycle, the generalist Ixodes ricinus takes up three blood meals from a wide selection of vertebrate hosts, some of which are reservoirs for multiple vector-associated pathogens. Since I. ricinus also readily bites humans, pets, and livestock, these hosts are at risk of becoming infected with more than one tick-borne pathogen.

Survival and localization of African swine fever virus in stable flies (Stomoxys calcitrans) after feeding on viremic blood using a membrane feeder.

Since 2014, African swine fever virus (ASFV) has been spreading within Eastern Europe. Within affected regions, the virus has infected some farms with high biosecurity and a marked seasonality of outbreaks in domestic pigs has been observed. ASFV transmission from stable flies, Stomoxys calcitrans, has previously been shown both mechanically and via ingestion of whole flies.

Infection of pigs with African swine fever virus via ingestion of stable flies (Stomoxys calcitrans).

Within Eastern Europe, African swine fever virus (ASFV) has unexpectedly spread to farms with high biosecurity. In an attempt to explain this process, pigs were allowed to ingest flies that had fed on ASFV-spiked blood, which had a realistic titre for an infected pig. Some of the pigs became infected with the virus.
