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.

AbstractIn a survey carried out during the period May 1995 to November 1996, in communities of various ethnic groups in northern Israel, 206 dogs were examined for Echinococcus granulosus and other intestinal helminth parasites by arecoline hydrobromide purges and the coproantigen-ELISA. The arecoline test was performed close to the owners' homes, using plastic sheets secured to the ground. From 56 dogs examined in the Muslim town of Tamra, six (10.7%) were found to be infected with E. granulosus. Four of them also had a mixed infection of Taenia hydatigena and Dipylidium caninum (two dogs), and the remaining two dogs were infected with either D. caninum or Taenia pisiformis. An additional 18 dogs were infected with either T. pisiformis (eight dogs), D. caninum (seven dogs), or T. hydatigena (three dogs). Two of these dogs harboured mixed infections whereas the remaining 32 dogs were free of helminths. In the Jewish villages, none of the 150 dogs examined were infected with E. granulosus, although 26 (17.3%) were infected with D. caninum, four (2.7%) with Ancylostoma spp. and one (0.7%) with Toxocara canis. Only one of the 22 stray dogs and none of the 15 jackals examined were infected with E. granulosus. However, 21 (95.4%) of the dogs and 12 (80%) of the jackals harboured helminth infections, including: D. caninum (16 dogs and seven jackals), Ancylostoma spp. (five jackals), T. hydatigena (three dogs), and T. canis (one dog). Approximately 18% of the dogs and 33% of the jackals showed mixed infections with two or more of the above helminths. In the abattoirs, 52 (5.9%) of the 874 sheep and 33 (5.3%) of the 616 goats from 17 herds slaughtered in the Muslim and Druze villages were found to be infected with E. granulosus, compared with a 0% infection rate observed in 93 sheep from two herds in Jewish villages.

Abstract In the present study, 64 golden jackals were examined for intestinal helminths in three regions of Vojvodina, Serbia. Among the examined jackals 57.8% were infected with at least one parasite species. Using the intestinal scraping technique (SCT), eight species of intestinal helminths were found: Alaria alata (7.8%), Toxascaris leonina (9.4%), Toxocara canis (4.7%), Uncinaria stenocephala (20.3%), Echinococcus multilocularis (14.1%), Mesocestoides sp. (42.2%), Taenia pisiformis, and Taenia hydatigena (the overall prevalence of Taenia infection was 6.3%). To the best of our knowledge, this is the first report of T. leonina in jackals from Serbia. In comparison with the SCT results, coprological tests were less sensitive and specific for parasite identification, as only two nematode species (T. leonina and T. canis) as well as ancylostomatid and taeniid eggs were identified. The total prevalence of intestinal helminths was higher in males (71.9% males, 45% females), but the difference was not statistically significant (χ 2 = 3.76; P = 0.052). Co-infection with two species of intestinal helminths was found in 35% of the examined golden jackal individuals, three-species co-infection was demonstrated in 21.6%, whereas four-species co-infection was detected in 2.7% of the golden jackals examined. Echinococcus multilocularis has previously been recorded in jackals and foxes in Serbia, but only in Vojvodina. Our results corroborate the findings of previous studies, and indicate that the Vojvodina Province, more specifically the Srem region, is probably a high-risk area for E. multilocularis transmission to humans.

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 Status

Abstract Sixteen intestinal helminth species were recovered from 271 necropsied stray dogs during a survey undertaken in Raoued and Soukra, two northeastern rural regions of Tunisia. Recorded parasites included trematodes (Brachylaemus sp., Phagicola italica, Heterophyes heterophyes), cestodes (Echinococcus granulosus, Dipylidium caninum, Diplopylidium noelleri, Mesocestoides lineatus, Mesocestoides litteratus, Taenia hydatigena, Taenia pisiformis, Taenia multiceps), nematodes (Toxocara canis, Ancylostoma caninum, Uncinaria stenocephala, Trichuris vulpis) and one acanthocephalan Macracanthorhynchus hirudinaceus. This is the first record of Brachylaemus sp., P. italica, H. heterophyes, D. noelleri and M. hirudinaceus in dogs from Tunisia. Echinococcus granulosus was found in 5·16% of dogs with a higher intensity of infection recorded in younger animals (303 worms/infected dog). Molecular analysis confirmed E. granulosus sensu stricto as the cause of canine echinococcosis. This epidemiological study investigating the status of intestinal helminths of dogs recorded a prevalence of 98·89% and a mean intensity of 87·62 worms per infected dog and confirmed the infection of 95·14% of dogs with helminths of potential zoonotic concern. Results of this study emphasize the need to interrupt parasite transmission using preventive approaches in zoonoses control programmes mainly against cystic echinococcosis, as well as reducing transmission to other animals by regular dog dosing treatments and proper management of dog populations.

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.

SummaryA total of 180 foxes (Vulpes vulpes) from an area scarcely investigated of north-west Italy, were examined for intestinal helminths using sedimentation and counting technique (SCT). Faecal samples were submitted to centrifugation with 50 % zinc sulphate used as flotation solution.No fox was found completely negative for intestinal helminths. The most frequently identified nematodes were Uncinaria stenocephala (70.0 %), Molineus legerae (27.2 %), Toxocara canis (26.7 %), Toxascaris leonina (25.6 %), Trichuris vulpis (21.1 %), Aonchotheca putorii (8.9 %), Pterygodermatites affinis (5.6 %). Genus Mesocestoides (81.7 %), family Dilepididae (29.4 %) and Taenia spp. (8.3 %) were the most prevalent cestodes. All foxes were negative for E. multilocularis and E. granulosus. In two foxes trematodes belonging to the family Plagiorchidae were found.The study highlighted that foxes are hosts of intestinal helminths of veterinary and medical importance which may be transmitted to dogs and humans.

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.

ABSTRACTThe activities of the enzymes superoxide dismutase (E.C.:1.15.1.1) and catalase (E.C: 1.11.1.6) were studied in purified extracts of four nematodes: Ascaris suum, Toxascaris leonina, Toxocara canis and T. cati adult males and females. No catalase activity was found in any of the extracts. The results reveal that the SOD activities of the four parasites presented species differences and also sexual differences within each species. Polyacrylamide gel electrophoresis pattern analysis confirmed that the mobilities, widths and band intensities varied according to the species and sex of the parasite from which the enzyme was obtained.

Summary We determined the prevalence of primarily zoonotic parasites in the small intestines of 40 (20 males and 20 females) red foxes living near human dwellings. The total prevalence of parasite infection was 77.5 % (31/40); the prevalence was 37.5 % (15/40) for Toxocara canis and 35 % (14/40) for Toxascaris leonina. The mean intensity infection was 3 and 11 helminths for T. canis and T. leonina, respectively. The prevalence of other intestinal helminths and mean infection intensity in this study are given: Echinococcus multilocularis 40 % (16/40) with 1000 individuals, Mesocestoides spp. 40 % (16/40) with 8 individuals, Uncinaria stenocephala 10 % (4/40) with 8 individuals, and Taenia pisiformis 10 % (4/40) with 1 individual. With regards to prevalence and intensity of infection, as well as prevalence of individual parasites, there were no significant differences (P≥0.05) between male and female red foxes.
