“…Other studies in urban areas in Brazil also revealed low frequency of Cryptosporidium in dogs. Gennari et al (1999) have found 2.8% of 353 animals shedding Cryptosporidium. Funada et al (2007) found 2.4% of positivity for Cryptosporidium in 1,755 samples of dogs, collected between January 2000 and December 2004.…”

The aim of this study was to assess the occurrence of Cryptosporidium in domestic animals in rural properties surrounding rain forest fragments within the municipality of Teodoro Sampaio, southeastern Brazil. Conventional sucrose flotation method followed by molecular characterization of the parasites by sequencing PCR products amplified from SSU rRNA gene were used. Stool samples were collected from domestic animals raised as pets and livestock in all rural properties surrounding three forest fragments. Samples from cattle (197), equine (63), pigs (25), sheep (11), and dogs (28) were collected from 98 rural properties. The frequency of occurrence of Cryptosporidium within each animal species was 3.0% (6/197) among cattle and 10.7% (3/28) among dogs. Cryptosporidium was not detected in stool samples from equine, sheep, and pigs. All sequences obtained from the six samples of calves showed molecular identity with Cryptosporidium andersoni while all sequences from dog samples were similar to C. canis. The frequency of occurrence of Cryptosporidium in these domestic animal species was low. The absence of C. parvum in the present study suggests that the zoonotic cycle of cryptosporidiosis may not be relevant in the region studied. The presence of Cryptosporidium species seldom described in humans may be, otherwise, important for the wild fauna as these animals are a source of infection and dissemination of this protozoan to other animal species. The impact and magnitude of infection by C. andersoni in wild ruminants and C. canis in wild canids have to be assessed in future studies to better understand the actual importance of these species in this region.

“…and Cryptosporidium spp. (GENNARI et al, 1999(GENNARI et al, , 2001. Not only stray dogs and cats, but also domestic animals are important in the epidemiology of such zoonosesand play an important role, since they generally frequent public places that are also visited by other animals and humans, thus leading to a high likelihood of infection by parasitic agents (LABRUNA et al, 2006).…”

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.Keywords: Dogs, helminths, protozoa, São Paulo, Brazil. ResumoA ocorrência de parasitos gastrintestinais foi estudada em amostras fecais de 3099 cães, da região metropolitana de São Paulo, SP, tratados no Hospital Veterinário da Faculdade de Medicina Veterinária da Universidade de São Paulo. As amostras foram analisadas por métodos de flutuação e centrífugo-sedimentação. Os resultados foram comparados com estudos prévios (diferentes períodos). Associação entre as frequências de cada parasito e idade, raça, sexo, ocorrência de diarreia e uso de anti-helmínticos foram analisadas pelo teste do qui-quadrado ou exato de Fisher. O qui-quadrado estratificado foi utilizado para comparar a ocorrência de cada parasito e os períodos analisados. Do total 20,5% das amostras eram positivas e 16,1% destas (102/635) apresentaram mais de um gênero de parasitos. Ancylostoma spp. (7,1%) e Giardia spp. (5,5%) foram os mais frequentes helminto e protozoário, respectivamente. Ancylostoma spp. foi associado (p<0,05) com idade (> 1 ano), animais sem raça definida, sexo (macho) e a não utilização de anti-helmínticos. Cães < 1 ano e mestiços apresentaram associação com ocorrência de Toxocara canis e cães jovens com Giardia spp, Cryptosporidium spp. e Cystoisospora spp. Giardia spp. também apresentou associação com cães de raças definidas (p<0,05). Para todos os parasitas analisados a incidência diminuiu no último período analisado quando comparado aos anteriores.

Ectoparasitos e helmintos intestinais em ResumoOs objetivos da realização deste trabalho foram determinar a prevalência de ectoparasitos e parasitos gastrointestinais (GI) em gatos domiciliados, nas regiões central e periférica, da cidade de Lages, SC e também caracterizar as famílias proprietárias de gatos quanto as suas condições sócioeconômicas e culturais. No período de dezembro de 2005 a dezembro de 2006, foram distribuídos 600 questionários a proprietários de animais cidade de Lages, SC e coletados ectoparasitos e amostras de fezes. A prevalência para ectoparasitos foi de 13,8% (28/203) e para parasitos GI, 37,8% (42/111). A prevalência de parasitos em gatos domiciliados da região periférica foi maior que os da região central. Os ectoparasitos observados foram Ctenocephalides felis felis, C. canis e Ctenocephalides híbrido (C. felis felis × C. canis). Os ovos de helmintos intestinais identificados nas fezes de gatos foram Ancylostoma spp., Toxocara sp., Trichuris sp., família Taeniidae e Oncicola sp. Na região periférica, o maior número de animais positivos pertencia a proprietários de baixa renda salarial e pouca escolaridade. As populações residentes nos bairros da região periférica encontram-se mais expostas aos agentes com potencial zoonótico.Palavras-chave: Parasitos, gatos domiciliados, diagnóstico. AbstractThe purpose of this research was to determinate the prevalence of ectoparasites and gastrointestinal (GI) parasites in domiciliated cats, from central and peripheral region, of Lages city, Santa Catarina State and also characterize the economic, social and cultural status of families' pet owners. From the period of December 2005 to December 2006, 600 questionnaires were distributed to pet owners of Lages city and ectoparasites and faeces were collected. The prevalence of ectoparasites was 13.8% (28/203) and for GI parasites was 37.8% (42/111). The prevalence of parasites in domiciliated cats from the peripheral region were bigger than in the central region. The ectoparasites observed were Ctenocephalides felis felis, C. canis and Ctenocephalides hybrid (C. felis felis x C. canis). The intestinal helminths eggs observed in cats faeces were Ancylostoma spp., Toxocara sp., Trichuris sp., Taeniidae family and Oncicola sp. In the peripheral region, the largest number of positive animals belonged to owners of low-income wage and low education The peripheral region population are over exposed to potencial zoonotic agents.
