Coprological examination was used to estimate the prevalence of gastrointestinal parasites in stray and domiciled dogs from Botucatu, S?o Paulo State, Brazil. Risk factors for dog infection were assessed in relation to demographic, husbandry and management data. The dog owners completed a questionnaire survey on some aspects of dog parasitism such as parasite species, mechanisms of infection, awareness of zoonotic diseases and history of anthelmintic usage. Parasites were found in the faeces of 138 dogs, with an overall prevalence of 54.3%. Dogs harbouring one parasite were more common (31.4%) than those harbouring two (18.5%), three (3.2%) or four (1.2%). The following parasites and their respective frequencies were detected: Ancylostoma (37.8%), Giardia (16.9%), Toxocara canis (8.7%), Trichuris vulpis (7.1%), Dipylidium caninum (2.4%), Isospora (3.5%), Cryptosporidium (3.1%) and Sarcocystis (2.7%). Stray dogs were found more likely to be poliparasitized (P<0.01) and presented higher prevalence of Ancylostoma, T. canis and Giardia (P<0.01) than domiciled ones. Toxocara canis was detected more frequently in dogs with <6 months of age (P<0.05) and no effect of sex or breed could be observed (P>0.05). Except for Ancylostoma, that showed a significantly higher prevalence in dogs living in a multi-dog household (P<0.01), parasite prevalences were similar in single- and multi-dog household. The answers of dog owners to the questionnaire showed that the majority does not know the species of dog intestinal parasites, the mechanisms of transmission, the risk factors for zoonotic infections, and specific prophylactic measures. The predominance of zoonotic species in dogs in the studied region, associated with the elevated degree of misinformation of the owners, indicates that the risk of zoonotic infection by canine intestinal parasite may be high, even in one of the most developed regions of Brazil. 相似文献

The protozoan Giardia duodenalis is a mammalian-infecting parasite that produces diarrhoea and malabsorption in its hosts. A survey to investigate canine infections with G. duodenalis in Romania was undertaken between June 2008 and December 2009. The objectives of the study were to (i) estimate the prevalence of infection in different dog populations (kennels, shelters, shepherd, household) using microscopy and a commercially available enzyme-linked immunosorbent assay (ELISA) test kit; (ii) to establish the level of agreement and characteristics of the tests; and (iii) to identify risk factors for infection by multivariate logistic regression models. Faecal samples were collected from 614 dogs aged from 1 month to 16 years (mean ± SD=2.88 ± 2.86 years). Each sample was tested for the presence of cysts using a flotation method with saturated sodium chloride solution and 416 out of 614 stool samples were further examined for the presence of G. duodenalis specific antigens using Giardia Microwell ELISA (SafePath? Laboratories). Giardia cysts were identified in 8.5% of total dogs (52/614) and statistical significantly more frequently in dogs living in communities. The cysts prevalence according with dog populations was as follows: 7.2%(9/125) in kennel dogs; 16.5%(27/164 in shelter dogs; 4.3%(2/46) in shepherd dogs; 4.8%(4/84) in household dogs from urban areas; and 5.1%(10/195) in household dogs from rural areas. The overall prevalence of Giardia infection by ELISA was 34.6% (144/416). The prevalence was significantly higher in kennel dogs (50%; 13/26), shelter dogs (47.7%; 74/155) and shepherd dogs (40.5%; 17/42) than in household dogs from urban areas (34.1%; 15/44) and household dogs from rural areas (16.8%; 25/149). It was noticed poor agreement between microscopy and ELISA (k=0.19). The microscopy performed best, with an Youden Index of 0.74, a Se of 73.68% and a Sp of 100%. ELISA had 100% Sp, but only 19.44% Se. Young dogs (up to 12 months age) and living in communities were identified as risk factors for infection by multivariate logistic regression analysis. 71.2% (37/52) Giardia cysts positive dogs presented co-infections with other intestinal parasites: Toxocara canis (14/52; 26.9%), Isospora ohioensis (12/52; 23.1%), Ancylostoma caninum (9/52; 17.3%), Uncinaria stenocephala (7/52; 13.5%), Trichocephalus vulpis (6/52; 11.5%), Hammondia heydorni/Neospora caninum (5/52; 9.6%), Sarcocystis spp. (5/52; 9.6%), Isospora canis (4/52; 7.7%), Capillaria aerophila (3/52; 5.8%), Strongyloides stercoralis (2/52; 93.8%), Dipylidium caninum (1/52; 1.9%) and Toxascaris leonina (1/52; 1.9%). 相似文献

A total of 281 faecal samples from owned shepherd and hunting dogs were collected in the Serres Prefecture, Northern Greece and were examined for the presence of intestinal parasites. The overall prevalence of parasitism was 26% and the 11 species found were: Toxocara canis (12.8%), Trichuris vulpis (9.6%), Giardia spp. (4.3%), Isospora (Cystoisospora) spp. (3.9%), Ancylostoma/Uncinaria spp. (2.8%), Cryptosporidium spp. (2.8%), Alaria alata (2.5%), Strongyloides stercoralis (1.8%), Angiostrongylus vasorum (1.1%), Toxascaris leonina (0.7%) and Dipylidium caninum (0.3%). The prevalence of T. canis and Isospora (Cystoisospora) spp. was significantly higher in young than in adult dogs (p < 0.05). There was no significant difference in prevalence between genders, except for T. canis, which was more common in male dogs (p < 0.05). 相似文献

The prevalence of gastrointestinal parasites in stray dogs, and dogs with owners was investigated by fecal examinations from 271 dogs employing sedimentation, simple flotation and centrifugation-flotation methods. The centrifugation-flotation method, when compared to simple flotation or sedimentation methods was generally more accurate in the diagnosis of all intestinal parasites, but statistical differences were detected only in relation to Giardia spp. and Cystoisospora spp. (synonym Isospora spp.). The following parasites, with their respective prevalence, were diagnosed in the fecal samples: Ancylostoma spp. (23.6%); Toxocara canis (5.5%); Trichuris vulpis (4.8%); Spirocerca lupi (1.9%); Dipylidium caninum (0.7%); Giardia spp. (12.2%); Hammondia heydorni (2.6%); Cystoisospora spp. (8.5%); and Sarcocystis spp. (2.2%). The prevalence of most parasites was similar for dogs of mixed-breed and for dogs of a defined-breed, except for Cystoisospora spp. and T. canis which showed a significantly higher prevalence in mixed-breed dogs. The prevalence of Ancylostoma spp. (17.1%) was significantly lower in stray dogs than in those with an owner (31.9%) and the prevalence of Giardia spp. and Cystoisospora spp. was higher in stray dogs (P < 0.05). No effect of season on the occurrence of the different parasite genera could be observed, except for Ancylostoma spp., for which an increase in the percentage of dogs shedding eggs was observed at the beginning of Summer with a peak occurrence during April and May (Autumn). The prevalence of Ancylostoma spp., T. canis, T. vulpis, Giardia spp. and Cystoisospora spp. was higher in adult males than in adult females, but significant differences between the two groups occurred only with Giardia spp. Young animals were found to more frequently shed Nematode eggs in feces than adult animals. 相似文献

Coprological examination was used to determine the prevalence and intensity of gastrointestinal parasites of stray dogs impounded by the Society for the Prevention of Cruelty to Animals (SPCA), Durban and Coast, South Africa. Helminth and protozoan parasites were found in faeces of 240 dogs with an overall prevalence of 82.5% (helminth parasites 93.1% and protozoan parasites 6.9%). The following parasites and their prevalences were detected; Ancylostoma sp. (53.8%), Trichuris vulpis (7.9%), Spirocerca lupi (5.4%), Toxocara canis (7.9%), Toxascaris leonina (0.4%) Giardia intestinalis (5.6%) and Isospora sp. (1.3%). Dogs harbouring a single parasite species were more common (41.7%) than those harbouring 2 (15%) or multiple (2.1%) species. Ancylostoma sp., Toxocara canis and Giardia intestinalis have zoonotic potential and were detected in 66.7% of the samples. 相似文献

The prevalence of gastrointestinal parasites in dogs was studied in the province of Córdoba (southern Spain), with special attention to those parasites that can be transmitted to man. The experiment was completed with the examination of soil samples from public parks and city gardens. The study was carried out over a population of 1800 animals entered in the Control Animal Centre (CECA) by coprological methods, and within this group, 300 dogs were sacrificed and necropsied. The prevalence of any intestinal parasitic infection was 71.33%. The following parasites of the gastrointestinal tract were recorded: Isospora canis (22%), Isospora (Cystoisospora) spp. (10.22%), Sarcocystis (2.5%), Hammondia/Neospora (1.94%), Giardia canis (1%), Dipylidium caninum (13.2%), Taenia hydatigena (7.66%), Taenia pisiformis (4%), Uncinaria stenocephala (33.27%), Toxascaris leonina (14.94%), Toxocara canis (17.72%) and Trichuris vulpis (1.66%). Related to public health, it is important to point out the presence of T. canis only in puppies younger than one year and Uncinaria, more frequent in adult dogs. Soil samples of parks revealed the presence of eggs of Toxocara, and it suggests the existence of real risk for human infection. 相似文献

The prevalence and risk factors of non-systemic canine ecto- and endoparasitism and anthelminthic use in Murcia located at the centre of the Spanish Mediterranean coastal arch, was investigated by coprology and necropsy in up to 275 pet, city shelter and stray dogs in 2001-2004. Faecal parasite stages were detected in 25% of dogs. Species frequency was 6-10% for Toxocara canis, Ancylostomatidae spp., Toxascaris leonina and Isospora canis, and 0.4-1% for Trichuris vulpis, Giardia lamblia, and Dipylidium caninum. Logistic regression indicated that the risk of intestinal parasitism was highest for dogs 相似文献

A total of 2193 fecal samples from owned dogs were collected during the 2003-2004 period in Southern Greater Buenos Aires, and were evaluated for the presence of intestinal parasites by a flotation-centrifugation method. The overall prevalence was 52.4%, and the 11 species found were: Ancylostoma caninum (13%), Isospora ohioensis complex (12%), Toxocara canis (11%), Trichuris vulpis (10%), Sarcocystis sp. (10%), Giardia duodenalis (9%), Isospora canis (3%), Hammondia-Neospora complex (3%), Dipilydium caninum (18 cases), Cryptosporidium sp. (5 cases), and Toxascaris leonina (1 case). There was no significant difference in the overall prevalence between genders (female = 50.4%, male = 54.6%), and breeds (pure = 52.3%, mixed = 53%), but prevalence in puppies (<1 year) was higher than in adult dogs (62.7% versus 40.8%, respectively). Only the prevalence of A. caninum differed between genders, with higher values for males. The prevalences of six of the parasite species showed a decreasing trend with increasing host age, and an inverse pattern was found for two other species. The prevalences of three protozoa were significantly higher in pure-breed dogs, and those of two nematodes were significantly higher in mixed-breed dogs. The prevalences of T. canis, A. caninum, and T. vulpis were spatially heterogeneous with a clear Southwest-Northeast gradient. Only prevalences of Sarcocystis sp. and G. duodenalis showed seasonal variation. The frequency distribution of the number of species per fecal sample did not differ from a random distribution. Results obtained throughout the world were discussed. 相似文献

Canine babesiosis is a tick-borne parasitic disease caused by the intraerythrocytic parasites, Babesia canis and Babesia gibsoni. A lethargic, weak, American Staffordshire Terrier (pit bull) dog, which had regenerative, normocytic, normochromic anemia, was shown by polymerase chain reaction analysis to be infected with B. gibsoni. Transmission electron microscopy of ethylenediamine tetraacetic acid-treated blood disclosed many well-preserved, intraerythrocytic babesia trophozoites. Four morphologic forms of babesia trophozoites are described (small spheres, small rods, irregular forms lacking pseudoinclusions, and large spheres having pseudoinclusions) and are compared with intraerythrocytic forms of B. canis and B. gibsoni described in other light and electron microscopic studies of in vivo and in vitro Babesia infections. This is the first detailed transmission electron microscopic study of canine B. gibsoni-infected red blood cells in North America. 相似文献

Apart from their veterinary importance, the hookworms Ancylostoma caninum, Ancylostoma braziliense and Ancylostoma caninum are also capable of causing zoonotic disease in humans. A highly sensitive and species-specific PCR-RFLP technique was utilised to detect and differentiate the various canine Ancylostoma spp directly from eggs in faeces. This technique was utilised to screen 101 canine faecal samples from parasite endemic tea growing communities in Assam, India, as part as an ongoing epidemiological investigation into canine parasitic zoonoses. The prevalence of hookworms in dogs was found to be 98% using a combination of PCR and conventional microscopy. Overall, 36% of dogs were found positive for single hookworm infections with A. caninum, 24% positive for single infections with A. braziliense and 38% had mixed infections with both A. caninum and A. braziliense. No dogs were found positive for A. ceylanicum in the community under study. The high prevalence of A. caninum and A. braziliense in dogs in this community may account for the high incidence of cutaneous larva migrans (CLM) observed among the human population residing at the tea estates. The PCR-RFLP technique described herein allows epidemiological screening of canine hookworms to be conducted rapidly, with ease and accuracy, and has the potential to be applied to a number of different clinical, pharmacological and epidemiological situations. 相似文献
