“…Unlike shelter and household dogs, shepherd dogs seem to be more prone to taeniid infection, which possibly is due to the frequent consumption of raw meat and carcasses [2, 88]. Echinococcosis is still endemic in Greece with a high prevalence reported in livestock [89–91].…”

BackgroundThe objectives of this study were to evaluate the prevalence and infection intensity of intestinal parasites in different dog and cat populations in Crete, Greece, estimate the zoonotic risk and identify risk factors.MethodsFaecal samples from shelter, household and shepherd dogs and shelter and household cats were analyzed using sedimentation/flotation techniques. Giardia and Cryptosporidium were detected by a quantitative direct immunofluorescence assay (IFA). PCR and sequencing was performed to evaluate the zoonotic potential of Giardia and Cryptosporidium positive samples.ResultsTotals of 879 dog and 264 cat faecal samples were examined. In dogs, the overall prevalence was 25.2% (CI: 22.4–28.1) for Giardia spp.; 9.2% (CI: 7.3–11.1) for Ancylostoma/Uncinaria spp.; 7.6% (CI: 5.9–9.4) for Toxocara spp.; 5.9% (CI: 4.4–7.5) for Cryptosporidium spp.; 4.6% (CI: 3.2–5.9) for Cystoisospora spp.; 2.7% (CI: 1.7–3.8) for Toxascaris leonina; 1.7% (CI: 0.9–2.6) for Capillaria spp.; 0.8% (CI: 0.2–1.4) for taeniid eggs; 0.2% (CI: 0–0.5) for Dipylidium caninum; and 0.1% (CI: 0–0.3) for Strongyloides stercoralis. In cats, the prevalence was 20.5% (CI: 15.6–25.3) for Giardia spp.; 9.5% (CI: 5.9–13.0) for Cystoisospora spp.; 8.3% (CI: 5.0–11.7) for Toxocara spp.; 7.6% (CI: 4.4–10.8) for Ancylostoma/Uncinaria spp.; 6.8% (CI: 3.8–9.9) for Cryptosporidium spp.; 4.2% (CI: 1.8–6.6) for Capillaria spp.; 0.8% (CI: 0–1.8) for taeniid eggs; and 0.4% (CI: 0–1.1) for Hammondia/Toxoplasma. Concerning the risk factors evaluated, there was a negative association between age and Giardia infection and between age and T. leonina infection intensity for dogs. Sequencing results revealed the presence of mainly animal-specific G. duodenalis assemblages C and D in dogs and assemblages F, C and BIV-like in cats, with only a limited number of (co-)infections with assemblage A. As for Cryptosporidium, the dog-specific C. canis and the pig-specific C. scrofarum were detected in dogs and the cat-specific C. felis was detected in cats.ConclusionsHigh levels of parasitism in both dogs and cats were recorded. Giardia was the most prevalent parasite in all dog and cat populations except for shepherd dogs. Genotyping results suggest a limited zoonotic risk of Giardia and Cryptosporidium infections from dogs and cats in Crete. Taeniid eggs were more prevalent in shepherd dogs suggesting access to carcasses and posing a threat for cystic echinococcosis transmission. Infection rates of Toxocara spp. in both dogs and cats show that companion animals could be a significant source of infection to humans.Electronic supplementary materialThe online version of this article (doi:10.1186/s13071-017-1989-8) contains supplementary material, which is available to authorized users.

“…5 The first and only report of a field study of E. granulosus in Australian dogs using this test collected faeces from rural dogs in two relatively small geographical areas: around Yass in New South Wales (NSW) and the other around Mansfield and Whitfield in Victoria. 6 The authors reported 'an unexpectedly large proportion' of E. granulosus coproantigen-positive dogs (NSW 99/344 (29%), Victoria 37/217 (17.5%)).…”

ÖZAmaç: Bu çalışma, çoban köpeklerinde sindirim sistemi helmintlerinin yaygınlığını ve zoonoz öneme sahip türlerin varlığını belirlemek amacıyla yapılmıştır. Yöntemler: Dışkı örnekleri önce makroskobik olarak incelenmiş, daha sonra helmint yumurtaları yönünden formalin ethyl-acetat sedimentasyon ve ZnSO 4 flotasyon yöntemleri ile bakılmıştır. Results: Helminth infection was detected in 35.26% of sheep dogs. Taenia spp. was the most common helminth (12.05%), followed by Toxocara spp. (9.38%), Toxascaris leonina (6.25%), and Trichuris spp. (4.2%). The positive results in the E. granulosus and T. canis-specific PCRbased molecular tests were obtained in 14 of the Taenia egg-positive samples and in 5 of the Toxocara egg-positive samples from dogs. This study has suggested that coprophagy and feed raw offal and meat to dogs may be responsible for finding atypical helminth eggs in fecal samples from dogs in the absence of an actual infection. Conclusion: To make the diagnosis of their owned parasites of dogs, E. granulosus and T. canis which have zoonotic importance, feces must be examined by both conventional and copro-PCR techniques. In addition to dogs' feeding habits, other related factors must be taken into account in the epidemiology of helminth infection; thus, precaution and control measures will be more reliable.

Detection of Echinococcus granulosus coproantigens in faeces from naturally infected rural domestic dogs in south eastern Australia

Abstract: Echinococcus granulosus occurs commonly in rural dogs in south eastern Australia and an education program promoting the public health importance of responsible management of rural dogs is urgently needed.
