The intracellular protozoan is distributed worldwide and infects many species of warm-blooded animals. Most mammals, including humans, can serve as intermediate hosts. This pathogen, with its zoonotic potential, causes toxoplasmosis, a condition that can range from subclinical to fatal in humans.

is an obligate intracellular protozoan that causes toxoplasmosis in warm-blooded animals. Although most infections in humans and animals are subclinical, an infection can nevertheless be fatal. One of the important characteristics in the epidemiology of this parasite is waterborne transmission.

The urinary bladder and lower urinary tract of domestic and wild carnivores can be parasitised by filamentous nematodes from the genus (syn. ). Infestations are often asymptomatic, but severe courses in dogs and cats have been described.

Giardia duodenalis is a cosmopolitan flagellate that causes giardiasis, one of the most significant gastrointestinal diseases in humans. This parasite can be a serious threat to public health because it can cause waterborne outbreaks as well as sporadic infections in humans. Invasive raccoons (Procyon lotor) may play a role in disseminating Giardia into the environment and transmitting it to humans and domestic animals because they live in high densities and deposit their faces in latrines near areas used by humans.

Background: Cryptosporidium spp. are protozoan parasites that cause enteric infection in a wide range of mammals, including humans. The raccoon (Procyon lotor) is an invasive species in many parts of the world and studies have shown that they can be infected with Cryptosporidium spp.

Infestation with Baylisascaris procyonis, a gastrointestinal nematode of the raccoon, can cause fatal disease in humans. We found that the parasite is widespread in central Germany and can pose a public health risk. The spread of B.

Article Synopsis
  • - The study analyzed total mercury (THg) and selenium (Se) levels in the hair of raccoons and European wildcats from Germany and Luxembourg, finding varying concentrations of these elements among species and locations.
  • - Raccoons had higher selenium levels (0.851 mg/kg) compared to wildcats (0.641 mg/kg), with raccoons from Luxembourg showing significantly higher THg levels than those from Germany (0.369 vs 0.273 mg/kg).
  • - The Se:THg molar ratio was much higher in German raccoons, about four times that of Luxembourg raccoons, and a significant negative correlation was observed between THg concentration and Se:THg ratio in both species.

European populations of free-living wildcats have been shown to be exposed to cat viruses. Luxembourg has a high degree of habitat fragmentation, and hybridisation rates between domestic cats and wildcats are high. We therefore assessed the seroprevalence of six viruses in 34 serum samples collected between 2001 and 2016 from wildcats in Luxembourg.

Despite increasing consumption of mouflon (Ovis orientalis musimon) meat in Germany, there is currently no surveillance of Toxoplasma gondii infection in populations of these animals and generally little knowledge about the prevalence of this protozoan in German wild ungulates. Between 2011 and 2015, we collected 138 blood samples from a free-living mouflon population in central German and tested sera for the presence of T. gondii antibodies using a modified agglutination test (MAT, cut-off 1:20).

Animal parasitic nematodes can cause serious diseases and their emergence in new areas can be an issue of major concern for biodiversity conservation and human health. Their ability to adapt to new environments and hosts is likely to be affected by their degree of genetic diversity, with gene flow between distinct populations counteracting genetic drift and increasing effective population size. The raccoon roundworm (Baylisascaris procyonis), a gastrointestinal parasite of the raccoon (Procyon lotor), has increased its global geographic range after being translocated with its host.

Parasites of an invasive species, the raccoon dog (Nyctereutes procyonoides) from western Poland were investigated to clarify poorly known ecological key aspects of the species. The research was conducted in two study areas: the Ujście Warty National Park and the Bogdaniec Forestry District. Intestinal samples were collected from the intestinal tracks of 39 dead animals and 51 faecal samples were collected in all seasons from latrines of raccoon dogs.

Trichinellosis is still one of the most important food-borne parasitic zoonoses and is considered as a threat to public health worldwide. The aim of this study was to use genotyping techniques to determine the prevalence of Trichinella species in wild raccoon dogs (Nyctereutes procyonoides) in western Poland. The infection rate in raccoon dogs was 0.
