    Seasonal prevalences of Cryptosporidium and Giardia infections in children attending day care centres in Salamanca (Spain) studied for a period of 15 months (1996)
    Springer
    European journal of epidemiology 12 (1996), S. 291-295

    Notes: Abstract Five studies were carried out in children younger than 4 years old attending regularly day care centres in order to determine the intestinal parasitization by Cryptosporidium and Giardia. The percent of children parasitized by Cryptosporidium was 10% (17 children out of 170 studied). Cryptosporidiosis was more frequent in winter than in other seasons (difference statistically significant). Giardia intestinulis which was the most frequent parasite, was identified in 25.3% (43 children out of 170 studied). Giardiasis was more frequent in autumn and in the low SEL (difference statistically significant in both cases). The frequency of giardiasis increased from 8% in children studied during 1–2 seasons, to 34% in children studied for 3–5 seasons (difference statistically significant), whereas the frequency of cryptosporidiosis did not show variation with increased number of specimens studied per child. The 35% of children parasitized by Cryptosporidium sp. showed gastrointestinal symptoms but only 14% of children with Giardia intestinalis.

    Epidemiology and clinical significance of Blastocystis hominis in different population groups in Salamanca (Spain) (1992)
    Springer
    European journal of epidemiology 8 (1992), S. 553-559

    Keywords: Blastocystis hominis ; Epidemiology ; Day care centres and primary schools ; Patients attending the hospital ; Clinical significance

    Topics: Medicine
    Notes: Abstract A prospective study was carried out to investigate the epidemiology and clinical significance of Blastocystis hominis in the following groups of the population of the city of Salamanca (Spain): in children attending 11 day car centres and 7 primary schools, two fecal samples were obtained from each child, and in 1231 patients attending the Clinical Hospital. A B. hominis incidence of 5.3–10.3% was found in the day care centres and an incidence rate of 13.4–19.4% was found in the primary schools. All the cases were observed in asymptomatic children. The incidence of B. hominis was greater in children older than 3 years in the day care centres and in the 10–14 year-old group in the primary schools. A heavier parasitization was observed in the boys than in the girls and in the students of schoold in areas of low socio-economic level. B. hominis was identified in 40 patients attending the Clinical Hospital (3.25% of all those studied). The maximum peak of incidence was found in subjects with ages between 10 and 14 years. A follow up study was performed on 18 patients parasitized exclusively by B. hominis; 7 of these were considered to have acute gastroenteritis and one chronic gastroenteritis associated with the protozoan. No statistically significant association was observed between the number of B. hominis cells and the presence of diarrhoea. Our results show that despite the high number of asymptomatic carriers of B. hominis in the juvenile population, this protozoan may be, on other occasions, responsible for gastrointestinal symptoms.

    Cryptosporidium oocysts in water for human consumption (1994)
    Springer
    European journal of epidemiology 10 (1994), S. 215-218 
    Details
    ISSN: 1573-7284
    Keywords: Cryptosporidium oocysts ; Staining methods ; Water
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract A study was carried out on the presence of oocysts ofCryptosporidium spp. in water for human consumption in the Province of Salamanca, Spain, using four different staining techniques: Ziehl-Neelsen, auramine, indirect immunofluorescence with monoclonal antibodies (Meridian, USA) and direct immunofluorescence with monoclonal antibodies (Pasteur, France). The presence of oocysts was detected in the water used for the washing of sand filters in the four water purifying plants and in the drinking water of two of the six geographical areas studied. The Ziehl-Neelsen and auramine staining techniques were found to have excellent diagnostic correlation. Immunofluorescence stainings with monoclonal antibodies proved to be less sensitive.
