“…According to the literature, the numbers of opportunistic infections in HIV/AIDS patients 13 has diminished considerably since the introduction of HAART in 1996, including cases of cryptosporidiosis. However, in this study it was impossible to determine the influence of this therapy on infections with Cryptosporidium sp and Cystoisospora belli, since only 8.5% of patients which presented coccidian regularly received HAART.…”

“…3 The parasite attaches itself to the intestinal epithelium of the host, resulting in varying degrees of villous atrophy and inflammatory infiltration of the lamina propria. 4 The clinical presentation is highly variable, but is frequently characterized by watery diarrhea, sometimes accompanied by abdominal pain, low-grade fever, malaise, nausea, vomiting, and loss of appetite. Symptoms usually appear 2-10 days after infection and can last for a few weeks.…”

Abstract. The risk factors for acquisition of cryptosporidial infection in resource-poor settings are poorly understood. A nested case-control study was conducted to assess factors associated with childhood cryptosporidiosis (detected by stool polymerase chain reaction) in an endemic, Indian slum community using data from two community-based studies with 580 children followed prospectively until their second birthday. Factors were assessed for overall cryptosporidiosis (N = 406), and for multiple (N = 208), asymptomatic (N = 243), and symptomatic (N = 163) infections, respectively. Presence of older siblings (odds ratio [OR] = 1.88, P = 0.002) and stunting at 6 months of age (OR = 1.74, P = 0.019) were important risk factors for childhood cryptosporidiosis. Always boiling drinking water before consumption, the use of a toilet by all members of the family, and maternal age 23 years were protective. These results provide insights into acquisition of childhood cryptosporidiosis in settings with poor environmental sanitation, contaminated public water supply systems, and close human-animal contact. Disease control strategies will require a multifaceted approach.

Giardia spp. e Cryptosporidium spp. em água de manancial superficial de abastecimento contaminada por dejetos humano e animal [Giardia spp. and Cryptosporidium spp. in RESUMOEstudou-se ocorrência de cistos de Giardia spp. e oocistos de Cryptosporidium spp. -(oo)cistos -na bacia hidrográfica do Ribeirão São Bartolomeu, localizada no município de Viçosa, MG. O estudo incluiu as populações humana e animal existentes na área da bacia, bem como no efluente de uma estação de tratamento de esgoto (ETE) e de duas instalações para suínos. Os resultados indicam presença de (oo)cistos no manancial (médias geométricas: 3,92 e 3,62 (oo)cistos/l para Giardia spp. e Cryptosporidium spp., respectivamente). Propriedades com exploração bovina foram positivas ao longo de todo período (prevalência média de propriedades positivas 36,4% para Giardia spp. e 18,0% para Cryptosporidium spp.). O efluente da ETE apresentou elevada concentração de cistos de Giardia spp. (média geométrica na ordem de 10 4 /l), mas não foram encontrados oocistos de Cryptosporidium spp. A ocorrência de (oo)cistos apresentou comportamento sazonal, sendo que os valores médios de (oo)cistos e de pluviosidade do trimestre de coleta revelaram bom ajuste de correlação (R 2 =98,3%; P=0,0087 para Giardia spp. e R 2 =91,8%; P=0,0421 para Cryptosporidium spp.). A significativa ocorrência de (oo)cistos no manancial sugere que a forma de ocupação do solo interfere na qualidade parasitológica da água bruta. Os resultados apontam para a importância de adoção de medidas preventivas, como proteção de áreas de mananciais, objetivando reduzir riscos de transmissão de protozoários via água de consumo humano.Palavras-chave: água, manancial de abastecimento, Giardia spp., Cryptosporidium spp., qualidade da água (São Bartolomeu Stream-SB), at Viçosa city, MG. In the studied area, characterization of animal farms and identification of sewage and animal wastes discharges were undertaken. In addition, a sewage treatment plant (STP) and effluents of two swine farms were sampled.
