Abstract Free-ranging grey wolves (Canis lupus), which are presently recolonizing Italy, can be parasitized by a diversity of helminths, but have rarely been subject to studies of their parasites. Therefore, this study aims to determine the prevalence of gastrointestinal helminths of road-killed grey wolves from the Piedmont region of Italy. Forty-two wolves were collected and examined for the presence of helminths. We recorded 12 helminth species: nine Nematoda and three Cestoda. The nematodes were: Ancylostoma caninum (7.1%), Capillaria sp. (2.4%), Molineus sp. (2.4%), Pterygodermatites affinis (11.9%), Physaloptera sibirica (9.5%), Toxocara canis (9.5%), Toxascaris leonina (2.4%) and Uncinaria stenocephala (26.2%); the cestodes were: Dipylidium caninum (4.8%), Mesocestoides sp. (4.8%) and Taenia multiceps (76.2%). Physaloptera sibirica had the highest mean intensity and T. multiceps had the highest prevalence. Based on age and sex, no differences in the intensity or prevalence of helminth species were found among the hosts. Molineus sp. was recorded for the first time in wolves from the Palearctic region; P. affinis and P. sibirica are respectively reported for the first time in wolves from Europe and Italy.

AbstractEighty-nine samples of grey wolf (Canis lupus L.) faeces were collected between 2002 and 2004 from two areas in the western Beskidy Mts (south Poland). Helminth eggs were observed in 56.2% of faeces examined. These included: Alaria alata (2.2%), taeniid eggs (11.2%), Toxocara canis (5.6%), Toxascaris leonina (1.1%), Eucoleus aerophilus (14.6%), Ancylostoma caninum (12.3%), Uncinaria stenocephala (37%) and unidentified roundworm eggs of the family Strongyloididae (1.1%). Eucoleus aerophilus is recorded for the first time from Poland. The results are compared with the helminth fauna of other wolf populations in Europe.

AbstractThe prevalence of helminth species in stray dogs, from the capital city of the state of Queretaro, was evaluated. A total of 378 dogs were captured and examined for the presence of helminths from January to December 2008. The results showed that 275 (72.8%) of examined dogs were infected with one or more helminth species. Single infections were observed in 139 (50.5%) of infected dogs and 136 (49.5%) harboured mixed infections. Out of the 378 dogs examined, 208 (55.2%) presented nematodes and 182 (48.1%) cestodes. The prevalences (confidence interval) and mean intensities of infection ( ± SD) of nematodes and cestodes encountered were:Ancylostoma caninum42.9% (37.9–47.8) and 22.1 ( ± 34.3);Toxocara canis15.1% (11.8–19.0) and 8.3 ( ± 15.0);Spirocerca lupi4.5% (2.7–7.1) and 3.9 ( ± 4.8);Toxascaris leonina2.3% (1.1–4.5) and 4.8 ( ± 3.5);Physaloptera praeputialis1.9% (0.8–3.8) and 9.7 ( ± 14.9);Dirofilaria immitis1.3% (0.4–3.1) and 5.6 ( ± 2.1);Oslerus osleri0.3% (0.0–1.6) and 5 ( ± 0.0);Dipylidium caninum44.9% (40.0–50.0) and 18.1 ( ± 27.7);Taeniaspp. 6.9% (4.7–9.9) and 6.9 ( ± 7.1). There were no significant differences in prevalences observed either between female (68.5%) and male (76.8%) or between young (70.6%) and adult (74.2%) animals. No differences were observed in the ANOVA test for the mean intensity of infection of any of the parasites (P>0.05).

The grey wolf (Canis lupus L.) is the most widespread large carnivore in Europe with large populations in the Eastern part of Europe and the Balkan Peninsula. In this study, a total of 102 wolves were examined for intestinal helminth parasites. The carcasses were collected within the Serbian part of the wolf’s range during the period 2009–2014. Nine helminth species were found: one nematode, Toxocara canis (3.9%), one trematode, Alaria alata (1.0%), and seven cestodes, Taenia pisiformis (1.0%), T. hydatigena (9.8%), T. polyacantha (2.9%), T. taeniaeformis (2.0%), T. (syn. Multiceps) multiceps (3.9%), T. serialis (1.0%) and Mesocestoides litteratus (1.0%). Taenia (syn. Hydatigera) taeniaeformis has been registered for the first time in a wolf from Europe. An overall moderate prevalence (16.7%) of infected wolves was recorded. There was no statistically significant difference in prevalence between sexes. Of the years studied, the highest prevalence was found in 2014 (57.1%). The maximum number of helminth species per host specimen was four.

Background: We present a study about helminth parasites in wolf (Canis lupus signatus) from Sierra de la Culebra, a protected area in the Northwest of Spain, where is the largest population of wolves of the Spanish territory and one of the largest in Western Europe. Materials and Methods: To this aim, 93 fecal samples were collected during May and June of 2013 using 33% zinc sulphate flotation technique and classified based on their morphology, color, structure and size. Results: Parasites were present in 66.67% of the samples and classified as Eucoleus aerophilus (50.54%), Strongyloides sp. (27%), Ancylostomidae gen. sp. (19.35%), Toxocara Canis (10.75%), Taeniidae gen. sp. (9.68%), Trichuris vulpis (9.68%) and Toxascaris leonina (2.15%). Their distributions were very heterogeneous with the highest prevalence being in Northwest Spain. These differences found can be attributed to local environmental factors (ambient temperature, humidity) as well as animal feeding and social behavior. Conclusion: A wide helminthofauna is observed in the studied wolves, similar to other studies carried out in Europe (Estonia, Finland, Italy, Latvia, Poland, Portugal, Spain and Sweden). In addition, this study constitutes the first description of the presence of Strongyloides sp. in Iberian wolf in Spain.

Une étude parasitologique a été menée en 2015 sur des chiens de sexe, âge et race différents, vivant en liberté dans la ville de Lubumbashi, République démocratique du Congo. Des échantillons de fèces ont été prélevés et analysés par coproscopie selon une méthode de flottation. Sur les 120 chiens examinés, 78 (65 %) étaient infestés, parmi lesquels 74 (61,7 %) avaient des helminthes gastro-intestinaux et 4 (3,3 %) avaient des coccidies. Les coproscopies ont révélé la présence de cinq espèces de parasites : Ankylostoma spp. (41 chiens), Toxocara canis (22), Toxascaris leonina (8), Isospora canis (4) et Dipylidium caninum (3). I. canis n’a été retrouvé que chez les chiots. Le dépistage fréquent d’ankylostomes et de T. canis suggère qu’il existe à Lubumbashi un risque de contamination de l’homme par ces parasites zoonotiques.

AbstractA study of gastrointestinal parasites in 269 faecal samples from dogs (Canis familiaris) collected from Ile-Ife, Nigeria between January and December 2004, revealed seven helminth species:Toxocara canis33.8%,Ancylostomasp. 34.6%,Toxascaris leonina3.3%,Trichuris vulpis3.7%,Dipylidium caninum4.1%,Uncinaria stenocephala0.7% andTaeniasp. 1.1%. The faecal egg intensities, determined as mean eggs per gram of faeces ( ± SEM) were:T. canis393.8 ± 83.4,Ancylostomasp. 101.5 ± 32.8,T. leonina14.3 ± 7.9,T. vulpis3.4 ± 1.5,D. caninum2.2 ± 0.8,U. stenocephala0.2 ± 0.2. The prevalence of intestinal parasites was significantly higher (P < 0.05) in dogs of age 0–6 months than in older age groups. There was no significance difference in overall prevalence of intestinal helminth parasites between male (58.3%) and female (50.0%) dogs (P>0.05). The prevalence of helminth parasites was significantly higher (P < 0.05) in free-ranging than in kennelled dogs. The prevalence of helminth parasites was also significantly higher (P < 0.05) in African shepherds than in Alsatians and other exotic breeds. Each helminth parasite had similar prevalences and intensities among both genders (P>0.05) except inT. vulpis. The overall prevalence of intestinal parasites may continue to rise due to lack of functional veterinary clinics for dog care in Ile-Ife. Therefore, there is the need to establish a veterinary facility in Ile-Ife.

Aims: To study the intestinal helminth fauna of domestic and neglected dogs living in the city of Samarkand and adjacent areas of the Samarkand region and to assess their epidemiological significance. Materials and methods: 112 dogs of different ages from Samarkand and the surrounding area were examined. 45 animals were examined by the method of incomplete helminthological autopsy; diagnostic deworming was performed in 12 priotarny dogs; in 55 dogs, feces were examined once by the Fulleborn method. Results: In the examined dogs, 4 types of cestodes and 4 types of nematodes were found in the intestines. The most common type was dog tapeworm (Dipylidium caninum). The extent of invasion (EI) is 73.7%, the intensity of invasion (AI) is 5-56 copies. Taenia hydatigena tapeworm was detected during preventive deworming in 5 animals out of 12 (41.7%), and at autopsy in 18 dogs out of 45 (40%), AI 1-4 copies. The tapeworm of Echinicoccus granulosus was found in the autopsy of one dog out of 45 (EI-4.4%, AI-more than 350 copies). Mesocestoides lineatus cestodes were observed in the autopsy of 3 dogs (EI-6.7%, AI-1-2 copies). Trichuris (=Trichocephalus) vulpis lived in the caecum of 20 dissected animals (EI-88%, AI-5-23 copies). During coproscopy of feces of 55 dogs, whipworm eggs were found in 25 animals (45.5%). Males and females of Toxocara canis were found in the intestines during autopsy of 5 animals (EI -22%, AI-2-4 copies). Eggs Toxocara coproscopy found in the feces of dogs 9 out of 55 (16.4 percent). The EI of the nematode Toxascaris leonina averaged 14.0%. AI 1-3 copies. The nematode Pterygodermatites (=Rictularia) affinis was found in the singular (male) in the duodenum of one dissected dog. Conclusions: In domestic and neglected dogs living in the territory of Samarkand and the Samarkand region, it was possible to establish the presence of 8 species of intestinal helminths, of which three species are dangerous to humans and have important epidemiological significance: Echinicoccus granulosus, Dipylidium caninum and Toxocara canis.

More than 1200 biological samplings were collected from the free-ranging dogs of various ages and biotopes that allowed to study the diversity of their helminth fauna. The results of investigations revealed that 95% of researched dogs are infested with multiple parasites mostly endoparasites (Eimeria canis, Dipilidium caninum, Echinococcus granulosus, Toxocara canis, Toxascaris leonina, Ancylostoma caninum and Trichocephalus vulpis.). It was established that the level of contamination with the all above mentioned parasites in free-ranging dogs is hogher in the adult dogs compared to the young ones. The young dogs were predominantly infested with parasites from the class Sporozoite (Eimeria canis) and the Nematoda class (Toxocara leonina). The level of contamination with parasites of the free-rangeging dogs is higher in the rural regions compared to the urban area.
