“…Samples of 20 g were obtained and taken directly from the anal blister and subsequently labelled by date, origin and medical record obtained from the owner. The samples were isolated in propylene bags and transported in thermal boxes at a temperature of 4°C, following Toscan et al, 18 to the Veterinary Parasitology Laboratory of the Catholic University of Temuco for processing. Once in the laboratory, the samples were deposited in 50 mL Falcon tubes with 30 mL of 70% ethanol for centrifugation at 1500 g for 15 min.…”

Background:There are no studies of potential zoonotic diseases in Mapuche communities' horses. Objectives:The objective of this study was to determine the prevalence of Cryptosporidium in horses of the Mapuche communities. Study design:This was a cross-sectional study.Methods: Faecal samples from 100 randomly selected horses (n = 100) were taken from rural Mapuche communities from four municipalities from the Araucanía Region.These samples were processed with the modified Ziehl-Neelsen staining technique and grouped by sex, age and municipality. Results:The general prevalence of Cryptosporidium spp. was 67.0% (n = 67). The prevalence was 51.0% (n = 51) in males and 49.0% (n = 49) in females, and there is no gender association to the presentation of Cryptosporidium spp. The prevalence by municipality was 60.0%, 80.0%, 64.0% and 64.0% in Curarrehue, Lonquimay, Padre las Casas and Teodoro Schmidt, respectively. The above shows no significant association between the sector and the presence of Cryptosporidium spp. The prevalence by age was 95.4% of horses tested positive for Cryptosporidium between birth and 6 years of age. About 27.3% of horses were tested positive in the age group between 7 and 10 years. There was no presence of Cryptosporidium spp. in the age group older than 11 years, showing a significant relationship between the age of the animal and the presence of Cryptosporidium (P ˂ 0.05). Main limitations:The sample analysis did not specifically identify the type of Cryptosporidium, and it was not possible to evaluate the zoonotic risk in the Mapuche communities.Conclusions: Cryptosporidium spp. is present in working horses in Mapuche communities, with a 67.7% general prevalence, and there is a significant association between this parasite and the age of the horses, being higher in the age group between 0 and 6 years, with a prevalence of 95.4%. There may be a potential zoonotic risk in the Mapuche communities.

RESUMO-Investigações relativas à criptosporidiose são fundamentais, tendo em vista o seu potencial zoonótico e sua patogenicidade em animais de produção e de companhia. Os equinos podem estar envolvidos na transmissão da infecção por Cryptosporidium e podem ter papel epidemiológico relevante nesta protozoose. A grande possibilidade destes animais se infectarem com este protozoário justifica a importância de se atentar para a ocorrência desta enfermidade. Objetivou-se demonstrar por meio de revisão de literatura, alguns aspectos epidemiológicos da criptosporidiose na espécie equina. Palavras-Chave Cryptosporidium, equino, coccídio. ABSTRACT-Inquiries about cryptossporidiosis are essential because its zoonotic potential and pathogenicity in pets and production animals. The horse can be involved in the transmission of the infection by Cryptosporidium and can have an epidemiological role in this disease. The great possibility of adquiring this protozoan, justify the importance of attempting against for the occurrence of this illness. The aim of this article was to demonstrated through literature revision, some epidemiological aspects of the cryptosporidiosis in the equine specie.

“…Dada à grande prevalência destes protozoários tanto na medicina veterinária quanto na saúde pública, diversos estudos foram realizados em animais domésticos, de companhia e de produção (NAVARRO et al, (1997), GENNARI et al, (1999, GUIMARÃES et al, (2001), ABE et al, (2002, OLIVEIRA-SEQUEIRA et al, (2002), BARTMANN, (2002, FIGUEIREDO et al, (2004), HUBER et al, (2005, ALVES ), THOMAZ, (2006), FONTANAROSSA et al, (2006, CAPUANO & ROCHA, (2006), MARTINEZ-MORENO et al, (2007), PAPAZAHARIADOU et al, (2007), MUNDIM et al, (2007), ALMEIDA et al, (2008), GOMES et al, (2008), RINALDI et al, (2008), PRESOTTO, (2009), PRATES et al, (2009), SEVÁ et al, (2010), TOSCAN et al, (2010). Estes estudos tiveram como objetivo avaliar a importância destes parasitos em relação à saúde dos animais, determinar fatores de risco que favorecem a infecção, avaliar a eficiência de fármacos no tratamento destas parasitoses e estimar o significado epidemiológico dos índices de prevalência em relação à saúde pública.…”

Dogs and cats are the most common domestic animals used for interact and live with humans. Even more these animals are sharing the same habitat with the human beings. Despite of the benefits of this intimate relationship, we must consider that dogs and cats can be hosts for zoonotic parasites, including Giardia and Cryptosporidium, both parasites with great relevance in veterinary medicine and public health. Giardia is a cosmopolitan enteric protozoan responsible for diarrhea in a wide variety of hosts, including man. Cryptosporidium is an emergent and opportunist parasite, which attained relevance with the advent of the acquired immune deficiency syndrome, since this parasite can cause severe disease in immunocompromised individuals. From an epidemiological standpoint, it is important to understand which are the Cryptosporidium species and Giardia genotypes which affect humans and animals, as well as know those with zoonotic potential. The prevalence rates knowledge of these parasites in canine and feline populations becomes an important tool that makes possible to delineate actions to reduce risk of transmission to other animals, as well as to the human population. The assemblages of Giardia duodenalis more prevalent in dogs and cats are also an important determination, since this protozoan has great genetic diversity and also the canine and feline's host species can harbor both zoonotic and species-specific assemblages. Through the use of traditional parasitological methods, the present study aimed to evaluate the prevalence of G. duodenalis and Cryptosporidium sp. in dogs (n=299) and cats (n=38) belonging to stray, community and semi-domesticated strata and captured by the Zoonosis Control Center of Campinas (CCZ), from March 2011 to March 2012. The positive samples for G. duodenalis have been molecularly characterized through locus tpi. The possible association among the epidemiological characteristics of the studied population with the infection by Giardia and Cryptosporidium, was also evaluated. The prevalence of G. duodenalis was 13.3% in fecal samples in dogs and statistical significant difference has been observed in relation to the consistency of the fecal sample, with higher prevalence in doughy or diarrheic samples. The prevalence of G. duodenalis in cats was 5.5%. In relation to Cryptosporidium, the prevalence in dogs was 2.0%. Oocysts were not found in fecal samples from cats. All amplified sequences sampled from dogs feces showed identity with C or D assemblage of G. duodenalis, suggesting that dogs belonging to evaluated strata constitute low risk to public health in the city of Campinas. The cat's fecal sample, which were possible to sequence, showed identity with the Assemblage AI, demonstrating that animals of this species belonging to this particular strata can be a concern in public health for the city of Campinas, since they can eliminate cysts with zoonotic potential.
