“…In this study, only one case of cryptosporidiosis was identified in a non-diarrheic sample. With regard to previous data in the region of detection in adults (9%) 36 and children (62%) 22 , we note that this profile can be related to age, which influences the distribution of the parasite, and the fact that the modified Ziehl-Neelsen stain does not normally detect this parasite as described for I. belli.…”

Introduction:We describe the epidemiology of intestinal parasites in patients from an AIDS reference service in Northeastern São Paulo, Brazil. Methods: Retrospective evaluation was done for all HIV-1/AIDS-positive patients whose Hospital de Base/São José do Rio Preto laboratorial analysis was positive for enteroparasites after diagnosis of HIV-1 infection, from January 1998 to December 2008. Statistical analysis was performed using the R statistical software version 2.4.1. The level of significance adopted was 5%. Results: The most frequent protozoan was Isospora belli (4.2%), followed by Giardia lamblia (3.5%), Entamoeba coli (2.8%), and Cryptosporidium parvum (0.3%). Ancylostoma duodenale (1.4%) was the most frequently detected helminth, while Taenia saginata and Strongiloides stercoralis were found in 0.7% of the samples. The results showed that diarrhea was significantly associated with giardiasis and isosporiasis. However, no association was observed between CD4 + cell counts, viral load, and the characteristics of any particular parasite. Conclusions: Our data may be useful for further comparisons with other Brazilian regions and other developing countries. The data may also provide important clues toward improving the understanding, prevention, and control of enteric parasites around the world. Keywords: Epidemiology. HIV-1. AIDS. Enteroparasites.

Métodos: Durante o período de janeiro de 1998 a dezembro de 2008, foi realizado este estudo retrospectivo por meio da análise dos prontuários dos pacientes diagnosticados com HIV-1/AIDS atendidos no Ambulatório de Doenças Infecto-Parasitárias do Hospital de Base, São José do Rio Preto, São Paulo. As análises estatísticas foram realizadas usando a versão 2.4.1 do software estatístico R. O nível de significância adotado foi de 5%. Resultados: O protozoário mais frequente foi o Isospora belli (4,2%), seguido da Giardia lamblia (3,5%), Entamoeba coli (2,8%) e Criptosporidium parvum (0,3%). O Ancylostoma duodenalis (1,4%) foi o helminto mais detectado, enquanto a Taenia saginata e o Strongiloides stercoralis foram observados em 0,7% das amostras. Os resultados mostraram que a diarreia foi significativamente associada com giardíase e isosporíase. Entretanto, nenhuma associação foi observada entre as contagens de células T CD4 + , carga viral e da característica de qualquer parasita em particular. Conclusões: Nossos dados podem ser úteis para futuras comparações com outras regiões do Brasil e outros países em desenvolvimento. Os dados também podem fornecer pistas importantes para a melhoria da compreensão, prevenção e controle de parasitas entéricos em todo o mundo. Palavras-chaves: Epidemiologia. HIV-1. AIDS.

“…1 In Brazil, a large variation in this parasite frequency has been observed and in some regions of São Paulo State, up to 40% of the population carries this protozoan. 2 Few molecular studies have been conducted in Brazil and discordant results were reported. In Rio de Janeiro city, Southeastern region of Brazil, only A1 and A2 subgenotype were found in human fecal samples and A1 subgenotype was the only one detected in the domestic animals isolates.…”

Objective: In order to evaluate the potential zoonotic transmission of Giardia duodenalis, isolates from humans and dogs in the Northwestern region of the São Paulo State, Brazil were characterized based on the β-giardin gene. Methods: The samples were analyzed by sequencing of the Nested-PCR products. Results: The A1 and A2 subgenotypes were detected in human and dogs. Cysts of assemblage B, C and D have not been found in any isolates studied. Conclusions: These results are consistent with the view that giardiasis in the largest endemic region of the Brazil should not be seen as a single entity.

¹ FCAV -Unesp Jaboticabal -andrelgalvao@hotmail.com ² FMV -Unesp Araçatuba RESUMO: Os protozoários do gênero Cryptosporidium sp. são parasitos que completam seu ciclo biológico na superfície de células epiteliais dos tratos respiratório, gastrointestinal e urinário de mamíferos, aves, répteis e peixes. A criptosporidiose é uma enfermidade que quando ocorre na forma de infecção natural, geralmente se apresenta assintomática ou com alterações gastrointestinais. Considerada uma zoonose, pois os animais quando infectados, principalmente os bovinos, constituem em fonte de infecção para o ambiente e para o homem, uma vez que eliminam grandes quantidades de oocistos em suas fezes. A sintomatologia quando presente é caracterizada por diarréia aquosa, desidratação, dores abdominais, perda de peso e morte, principalmente em indivíduos imunossuprimidos, e notadamente em paciente com vírus da imunodeficiência humana (HIV) e em crianças. Métodos terapêuticos eficazes no combate deste agente para os animais e para o homem, até o presente momento não foram estabelecidos, sendo aplicado o tratamento de suporte. Desta forma, trata-se de uma doença emergente, e a organização mundial de saúde a colocou na lista das doenças negligenciadas. Medidas de profilaxia são recomendadas como saneamento básico, utilização de métodos apropriados para a inativação dos oocistos e garantia de higiene pessoal constituem táticas para se minimizar a disseminação do Cryptosporidium. A presente revisão literária teve como objetivo descrever a importância da criptosporidiose em saúde pública. Palavras-chave: bovinos; cão; Cryptosporidium; gato IMPORTANCE OF CRYPTOSPORIDIOSIS AS ZOONOSIS ABSTRACT:The protozoa of the genus Cryptosporidium sp. are parasites that complete their life cycle on the surface of epithelial cells of the respiratory, gastrointestinal and urinary tracts of mammals, birds, reptiles and fish. Affected animals generally are asymptomatic but gastrointestinal disorders sometimes can be present. Criptoporidiosis is considered a zoonosis. Infected animals, especially cattle, are a source of infection for the environment and humans, because they eliminate large numbers of oocysts in their feces. The symptoms when present is characterized by watery diarrhea, dehydration, abdominal pain, weight loss and death, especially in immunosuppressed individuals, and especially in patients with human immunodeficiency virus (HIV) and children. Therapeutic methods effective to eliminate this agent in animals and humans has not been developed but it is necessary to applied support treatment. Criptosporidiosis is considered by the World Health Organization as an emerging disease. Basic sanitation, use of appropriate methods for the inactivation of oocysts and security of personal hygiene are recommended as Prophylactic methods to minimize the spread of Cryptosporidium. This literature review was aimed at describing the importance of cryptosporidiosis in public health.
