“…Outside Poland, a high percentage of A. alata infections (96%) was found in Lithuania, a country bordering Poland on the north-east [ 4 ]. Research in other European countries showed a moderately high or low prevalence of A. alata (5.5–31.4%) [ 3 , 6 , 7 , 37 , 38 , 40 , 41 ].

“…In Europe Taenia spp. have been commonly registered in foxes with a prevalence ranging between 8.3–62% [ 3 – 7 , 33 – 35 , 37 , 38 , 40 , 48 ]. It should be noted that the lowest percentage of infected foxes has been recorded in southern Europe (Italy; [ 40 ]), and the highest in Lithuania (the north-eastern part of the continent) [ 4 ].…”

Prevalence of intestinal helminths of red foxes (Vulpes vulpes) in central Europe (Poland): a significant zoonotic threat

et al. 2018

BackgroundThe red fox (Vulpes vulpes) is widely distributed in the world; in central Europe, it is the most numerous wild species of the family Canidae. It can play the role of a definitive host for many intestinal parasites, including zoonotic helminths. Poland, with its geographical location (central Europe), is an interesting area for parasitological investigations of this species. The aim of this study was to evaluate and compare the prevalence of intestinal helminths in red foxes in different regions of Poland.MethodsIntestines of 473 red foxes from four different regions were examined using the sedimentation and counting technique (SCT). In addition, 344 samples of faeces were examined using flotation.ResultsOverall, intestinal helminths were found in 98.9% of red foxes. The average prevalence of detected parasites was as follows: Mesocestoides spp. (84.1%); hookworms (67.9%); Alaria alata (61.5%); Toxocara/Toxascaris (49.5%); Taenia spp. (42.5%); Echinococcus multilocularis (25.6%); and Trichuris vulpis (2.3%). The prevalence of the majority of parasite species was similar in each region. Significant differences between regions were observed in the case of E. multilocularis: a low prevalence in the south-western and northern regions (0% and 0.9%, respectively) and a high prevalence in the south-east and northeast (39.3% and 42.7%, respectively). In the case of A. alata, important differences were found between northern (96.5% and 93.7% in northern and northeast regions, respectively) and southern regions (15.2% and 24.7% for south-western and south-east regions, respectively). The percentage of positive samples obtained with coproscopic examination (except for Trichuris) was significantly lower than that obtained with SCT. Analysis of the prevalence estimated in individual regions with the use of both methods (flotation and SCT) showed a high correlation for all parasite species (except for Mesocestoides spp.). The flotation method also allowed us to detect the eggs of the lung nematode Eucoleus aerophilus (syn. Capillaria aerophila) (76.2% of positive foxes).ConclusionsThis study showed a very high percentage of red foxes infected with intestinal helminths in different parts of Poland. Depending on the location, some differences were observed regarding the prevalence of dangerous zoonotic parasites, which should be considered in the assessment of infection risk for humans.

“…Among nematodes, roundworms from the family Toxocaridae are common, especially Toxocara canins and less frequently Toxocara cati and Toxascaris leonina [10,[15][16][17]. Other popular intestinal nematodes of red foxes are hookworms, most frequently belonging to the Uncinaria stenocephala and Ancylostoma caninum species [12,18,19]. There are differences in geographical distributions between these two species: Uncinaria infections concern colder parts of continents, while the area of Ancylostoma occurrence includes countries with a mild climate and relatively high temperatures [20].…”

Distribution of Parasitic Helminths in the Small Intestine of the Red Fox (Vulpes vulpes)

et al. 2020

The aim of the study was to analyze the distribution of the main groups of parasitic helminths within the small intestine of the red fox on the example of animals coming from eastern Poland. Two hundred and sixteen red foxes shot in eastern Poland were used in the investigation. Before examination, each small intestine was divided into three equal parts: anterior (A), middle (M), and posterior (P). Each part was examined separately with the sedimentation and counting technique. Six different types of intestinal parasites were detected: Alaria alata (78.7%), Mesocestoides spp. (78.2%), hookworms (72.7%), Taenia spp. (53.2%), Toxocara/Toxascaris (43.1%), and Echinococcus multilocularis (18.5%). Alaria alata was most often found in A and in the only-A variant. Taenia spp. and Toxocara/Toxascaris occurred often in A and were the second (after A. alata) parasites in terms of frequency occurring in the only-A variant. Mesocestoides spp. was most commonly located in M. Parasites with predilection sites located mainly in M and P were E. multilocularis and hookworms. In all parasite species, the variant covering the entire intestine (A + M + P) was found in samples with a higher intensity compared to variants limited to one or two fragments. Our investigation, as one of the few of its type, conducted a comprehensive analysis of the distribution of intestinal helminths in the small intestine of the red fox. It showed significant differences in the distribution of parasitic helminths in the small intestine of the red fox. Determining typical predilection sites for parasites in the intestine can be helpful in creating effective diagnostic methods.

Background: The red fox (Vulpes vulpes) is a widely distributed animal in the world. This wild carnivore is also a common host of several dangerous zoonotic parasites, primarily nematodes. Nematodes of red foxes, such as Toxocara canis and Uncinaria stenocephala, can cause numerous health problems in humans and domesticated animals. The aim of the study was to determine the parameters of occurrence of nematodes in red fox (Vulpes vulpes) in north-western Poland. Methods: The study was carried out in north-western Poland. The research material consisted of 620 red foxes (Vulpes vulpes). Parasitological sections of the foxes were taken using the sedimentation and counting technique.Results: The prevalence of infestations with nematodes was 77.3%, while the mean infection intensity was 20.1 per animal. The presence of Toxocara canis, Toxascaris leonina, Uncinaria stenocephala and Trichuris vulpis was noted. The greatest prevalence was presented by Uncinaria stenocephala (34.0%). Male and female foxes displayed a similar prevalence of nematodes. Their presence was recorded in the duodenum, jejunum, ileum and caecum of the foxes, and they were significantly more common in the jejunum than in other parts. The most commonly-observed coinfection was between Uncinaria stenocephala and Toxocara canis. Conclusions: It can be seen that nematodes are present in high numbers among foxes in north-western Poland. This phenomenon certainly contributes to an increased risk of transmission of parasites to humans and domestic animals, and this can represent a threat to health and even life.
