Detection of and an unknown -like nematode in raccoon ().

The raccoon (Carnivora: Procyonidae) is an invasive species of growing importance for the introduction of alien pathogens or as additional hosts for autochthonous pathogens in Europe, including zoonotic parasites. As the population is steadily increasing and outcompeting the red fox () in Germany, the consumption of raccoon meat raises concerns about pathogens they may transmit. Therefore the presence of larvae was here investigated in muscle samples (n = 904) of raccoons from northern Germany.

First detection of Trichinella spiralis in raccoon (Procyon lotor) in Germany.

Trichinella spp. are foodborne parasites that can cause severe and potentially fatal disease in humans. Infections occur through consumption of meat containing the infectious stage (L1).

Toxoplasma gondii in raccoons (Procyon lotor) in Germany: a serosurvey based on meat juice.

Toxoplasma gondii seroprevalence was determined in meat juice samples of 820 free-living raccoons from Germany. The animals were collected between December 2017 and April 2021. Using a commercial enzyme linked immunosorbent assay (ELISA), the overall seroprevalence was found to be 48.

Tick burden on European roe deer (Capreolus capreolus) from Saxony, Germany, and detection of tick-borne encephalitis virus in attached ticks.

Southern Germany is known as tick-borne encephalitis (TBE) risk area; however, the north of the country is almost free of human TBE cases. Due to its location in the transition zone between TBE risk areas and areas with only sporadic cases, Saxony is of importance in the surveillance of TBE. Roe deer (Capreolus capreolus), showing high seroprevalence of TBE virus (TBEV) antibodies, are considered to be sentinels for TBE risk assessment.

Distribution of Alaria spp. mesocercariae in waterfrogs.

The distribution of Alaria-spp.-mesocercariae within the host is relevant for the examination via Alaria spp. mesocercariae migration technique (AMT) regarding predilection sites and may indicate an interaction between parasite and host.

First detection of Baylisascaris procyonis in wild raccoons (Procyon lotor) from Leipzig, Saxony, Eastern Germany.

Baylisascaris procyonis is a zoonotic nematode mainly harbored by the North American raccoon. It can cause severe neurological problems in paratenic hosts and humans. In Germany, raccoons are spread throughout the country.
