Yeasts and filamentous fungi in bottled mineral water and tap water from municipal supplies
The main objective of this study was to analyse the occurrence of yeasts and filamentous fungi in drinking water as well as to investigate their correlation with the indicator bacteria of faecal pollution. Yeasts were detected in 36.6% and 11.6% of the bottled mineral on water dispensers and tap wat...

description | The main objective of this study was to analyse the occurrence of yeasts and filamentous fungi in drinking water as well as to investigate their correlation with the indicator bacteria of faecal pollution. Yeasts were detected in 36.6% and 11.6% of the bottled mineral on water dispensers and tap water samples from municipal system, respectively. Twenty-one (35.0%) of bottled mineral water and two (3.3%) of tap water samples were positive for filamentous fungi. For bottled mineral water 12 (20.0%) of 60 samples were positive for total coliform, compared with 3(5.0%)out of 60 samples from tap water. The mineral water from dispensers was more contaminated than tap water. Strains belonging to the genera Candida identified to the species level were C. parapsilosis, C. glabrata and C. albicans. Thus, bottled mineral water from water dispensers and tap water could be considered a possible transmission route for filamentous fungi and yeasts, and could constitute a potential health hazard, mainly to immunocompromised indivuals.<br>O principal objetivo do presente estudo foi avaliar a prevalência de leveduras e fungos filamentosos em água potável, bem como investigar suas correlações com bactérias indicadoras de contaminação fecal. Leveduras foram detectadas em 36,6% e 11,6% das amostras de água mineral de garrafão em dispensadores de água e água de torneira do sistema municipal, respectivamente. Vinte e uma (35,5%) das amostras de água mineral de garrafão e duas (3,3%) das amostras de água de torneira foram positivas para fungos filamentosos. Para água mineral de garrafão, 12 (20.0%) das 60 amostras foram positivas para coliforme total, comparado com 3 (5.0%) das 60 amostras de água de torneira. A água coletada de garrafões de água mineral dos dispensadores foi marcadamente mais contaminada que as amostras de água de torneira. Candida spp identificadas ao nível de espécie foram C. parapsilosis, C. glabrata e C. albicans. Como está sendo reportado, água mineral de garrafão em dispensador e água de torneira pode ser considerada como possíveis vias de transmissão de fungos filamentosos e leveduras, e podem constituir um potencial risco para a saúde, principalmente de pessoas imunocomprometidas. |
