Background and Aim: Uncinaria infection often appears in domestic dogs. In the present study, parasitological examination of fecal samples from 782 dogs were analyzed for the presence of Uncinaria stenocephala. Materials and Methods: Fecal samples were analyzed by means of a standardized flotation method using a saturated salt solution containing NaNO3 (specific gravity 1.38), with a centrifugation step. Results: The highest prevalence rates were found among young adult dogs (8.3%), followed by puppies (5.4%); the lowest prevalence rates were found in dogs older than 3 years (4.3%). The prevalence was 5.8% among female dogs and 7.2% in male dogs. Coinfections with roundworms and protozoan parasites were frequently observed in U. stenocephala-positive dogs (15%). In total, three types of coinfections were registered. Coinfection of U. stenocephala + Sarcocystids oocysts was recorded in 19.1% of the dogs (n=10). This may relate to higher prevalence of S. oocysts in dogs (n=153; 19.5%). There were two cases of coinfection of U. stenocephala + Toxocara canis (3.9%), which may relate to low prevalence of T. canis (3.9 %). One case of coinfection of Dipylidium caninum + U. stenocephala (0.1%) also appeared. Conclusion: The present study showed that male dogs and young dogs were most susceptible to U. stenocephala infection.

O estudo das parasitoses intestinais que ocorrem em cães nas áreas rurais do Brasil assume grande importância ante a escassez de trabalhos sobre este assunto. Foram coletadas amostras fecais de cães encontradas no solo de propriedades rurais de alguns municípios da região meio oeste do estado de Santa Catarina. No laboratório, as amostras foram processadas e analisadas pelo método de Hoffman e por centrífugo-flutuação em solução de sacarose. Verificou-se a presença de pelo menos um parasito em 56,0% das amostras. Os seguintes parasitos foram encontrados: Ancylostoma sp., Toxocara canis, Trichuris vulpis, Dipylidium caninum, Giardia sp., Cryptosporidium sp. and Taenia sp. / Echinococcus sp. Estes resultados indicam um nível elevado de contaminação do ambiente rural por parasitos de cães; por conseguinte, os níveis de infecção de cães na área estudada foram também elevados. O quadro sugere a necessidade da adoção de medidas eficazes de saúde pública e remete à discussão das possíveis implicações de tais resultados.

AbstractOne of the most common ectoparasites on domestic carnivores are fleas from the genus Ctenocephalides. This group of blood sucking insects are one of the most important in medical and veterinary terms, as they can serve as carriers of dangerous infectious and may cause other invasive diseases. Research studies have established a variety of fleas and other contagions parasitizing domestic dogs in Poltava, Ukraine. Certain peculiarities of these ectoparasitic studies, as a part of mixed infestations of dogs, have recently been determined. The results of the studies have shown that the species composition of the fleas was represented by two main species. The dominant species was Ct. felis, and their prevalence was 36.05 %. Another species (Ct. canis) was diagnosed less often and had a prevalence of 27.94 %. It was found that in 31.18 % of the dogs, the blood-sucking insects were mostly parasitizing in the form of an associations with: nematoda (Toxocara canis, Trichuris vulpis, Uncinaria stenocephala), Cestoda (Dipylidium caninum), protozoa (Cystoisospora canis), and another ectoparasite (Trichodectes canis). Overall, 33 types of mixed infestations were detected. Moreover, the number of different parasitic species in each dog ranged from one to seven. Fleas of the genus Ctenocephalides (in the composition of two species of parasites) were registered the most often (14.60 %). The infestation of dogs with other forms of mixed infestations was 0.69—8.01 %. The most frequent co-members for Ct. felis were Cestoda [D. caninum (13.47 %)], for Ct. canis—Cestoda [D. caninum (11.23 %)] and Nematoda [T. vulpis (8.29 %)].

Gastrointestinal (GIT) parasites of domestic cats (Felis catus) not only cause morbidity but are also potential zoonotic agents. The current study aimed at establishing the prevalence of GIT parasites in cats kept by households in Thika region, Kenya. Fecal samples were collected randomly from 103 cats and analyzed for presence of parasites using standard parasitological methods. In descending order, the prevalence of the detected protozoa parasites wasIsosporaspp. 43.7% (95% CI: 40.4–47%),Cryptosporidiumspp. 40.8% (95% CI: 37.5–44.1%),Toxoplasma gondii7.8% (95% CI: 4.5–11.1%), andEntamoebaspp. 2.9% (95% CI: 1.6–6.2%). The prevalence of the observed helminths wasStrongyloides stercoralis43.7% (95% CI: 40.4–47%),Toxocara cati23.3% (95% CI: 20–26.6%),Ancylostomaspp. 9.7% (95% CI: 6.4–13%),Dipylidium caninum8.7% (95% CI: 5.4–12.0%), andAcanthocephalaspp. 1.9% (95% CI: 1–4.2%). The percentage of cats excreting at least one species of parasite was 73.2% (95% CI = 69.9–76.5%). The study shows that the cats have high spectrum (9) of parasites which are known to affect the cat’s health and some are of zoonotic significance.

Fecal samples from cattle in 100 feedlots in 13 states were bacteriologically cultured for Escherichia coli O157 that did not ferment sorbitol, lacked beta-glucuronidase, and possessed genes coding for Shiga-like toxin. In each feedlot 30 fresh fecal-pat samples were collected from each of four pens: with the cattle shortest on feed, with cattle longest on feed, and with cattle in two randomly selected pens. E. coli O157 was isolated from 210 (1.8%) of 11,881 fecal samples. One or more samples were positive for E. coli O157 in 63 of the 100 feedlots tested. E. coli O157 was found at roughly equal prevalence in all the geographical regions sampled. The prevalence of E. coli O157 in the pens with cattle shortest on feed was approximately threefold higher than for randomly selected and longest on feed pens. Of the E. coli O157 isolates found in this study, 89.52% expressed the H7 flagellar antigen. E. coli O157 was found to be widely distributed among feedlot cattle, but at a low prevalence, in the United States.

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 Occurrences of gastrointestinal parasites were assessed in fecal samples from 3,099 dogs in the metropolitan region of São Paulo, SP, that were treated at the Veterinary Hospital of the University of São Paulo Veterinary School. The samples were analyzed using the flotation and centrifugal sedimentation methods. The results were compared with those from previous studies (at different times). The frequency of each parasite was correlated with the dogs’ ages, breeds and gender, as well as the occurrences of diarrhea and the use of anthelmintics, by means of the chi-square or Fisher exact test. Partitioned chi-square tests were used to compare occurrences of each parasite and the times analyzed. Out of the total number of samples, 20.5% were positive and 16.1% (102/635) of these presented more than one genus of parasites. Ancylostoma spp. (7.1%) and Giardia spp. (5.5%) were the most frequent helminths and protozoa, respectively. Ancylostoma spp. was associated (p<0.05) with age (over one year), mixed breeds, sex (male) and no use of anthelmintics. Dogs under one year and mixed breeds were associated with occurrences of Toxocara canis; and younger dogs with Giardia spp., Cryptosporidium spp. and Cystoisospora spp. Giardia spp. were also associated with dogs with a defined breed (p<0.05). All the parasites analyzed presented lower incidence in the last period analyzed than in the previous periods.

The results of the examination of 543 faecal specimens by the Merthiolate Iodine Formaldehyde Concentration (M.I.F.C.) technique, Willis's salt flotation method and by direct saline smear are given.The appearances of helminth ova and protozoan parasites in M.I.F.C. preparation are described.The M.I.F.C. method showed a much greater efficiency for the detection of helminth ova over the other two methods. It did not prove as satisfactory for the detection of protozoan parasites. Effective concentration of trophozoite forms was not observed. The possible reasons for this are discussed.It is proposed to adopt this method in combination with the direct saline smear for routine use in this laboratory.
