RESUMO
An evaluation was made of the risk of contamination by faecal parasites in the population from the use of wastewater in agriculture. The study was based in 3 rural clusters in the northern region of Settat city, Morocco: 2 rural clusters exposed to untreated wastewater in agriculture and 1 not exposed. The sample comprised 333 people aged 3-60+ years: 214 exposed and 119 non-exposed. Stool samples were collected and examined for intestinal parasites. The results showed that the prevalence of intestinal parasitosis (i.e. evidence of at least 1 type of parasite) in the exposed group was significantly higher that the non-exposed group (66.4% versus 31.9%; relative risk 2.1). The household crowding index was also higher in the exposed group.

Cases of onychomycosis diagnosed by mycological examination in the parasitology and mycology laboratory (Children Hospital, Rabat, Marocco) over the 22-year period, between 1982 and 2003, have been reviewed. 17,177 dermatophytes have been isolated in 4,940 patients. Dermatophytes presented 61.46% of onychomycosis, yeasts Candida albicans were responsible in 25.5%, moulds in 1.53% and for 12% fungi identification was not determined (positive direct examination or negative direct examination and culture despite typical clinical aspect). The most frequent dermatophyte was Trichophyton rubrum (83.6%), followed by Trichophyton violaceum var. glabrum (9%) and Trichophyton mentagrophytes var. interdigitale (6.9%). Candida albicans was the prevalent yeast. Moulds were mainly Fusarium spp. (47%), followed Scopulariopsis brevicaulis (16%) and Aspergillus spp. (12%). Dermatophytes and moulds most commonly infected the toenails, yeasts the fingernails.
