“…The consumption of mineral water is quite popular among certain groups of the Brazilian population. Nowadays, Brazil has the sixth largest production of mineral water in the world, with a production of approximately 3.5 billion liters in 2000 (8). The reason for this popularity partly lies on the therapeutic and medicinal properties attributed to mineral water, but the concept of purity commonly associated with it also accounts for its increased consumption (14).…”

The quality of mineral water commercialized in Brazil regarding the microbial content was analyzed and the results were compared with the standards established by the current legislation. Results demonstrated there was no bacterial contamination, but several types of fungi were found. Therefore, bottled mineral water could be considered a possible route for the transmission of filamentous fungi and yeasts.

“…A resolução ainda define "água adicionada de sais" como sendo a água para consumo humano preparada e envasada e que contém um ou mais dos compostos previstos no regulamento 3 . A desconfiança sobre a água proveniente do sistema público de abastecimento é um dos fatores que, muitas vezes, levam à utilização de fontes alternativas, como a água envasada, no entendimento de que essa fonte é segura [4][5][6] . Ainda, estudos identificaram que outros fatores, como custo, comodidade, proteção à saúde e características organolépticas, podem influenciar a percepção da população sobre a qualidade da água envasada, orientando a opção pelo seu consumo ou não 4,[7][8][9][10][11] .…”

Cad. Saúde Colet., 2014, Rio de Janeiro, 22 (3): 224-32Resumo O objetivo deste trabalho foi caracterizar a qualidade microbiológica e física de águas envasadas comercializadas em Viçosa (MG) e compreender as percepções dos usuários relacionadas a essa fonte de abastecimento para consumo humano. O diagnóstico da qualidade da água envasada foi realizado por meio de avaliação microbiológica e física de amostras de quatro marcas de água mineral envasada em galão de 20 L. A qualidade dessas águas foi verificada por meio de análises bacteriológicas para Escherichia coli, coliformes totais, enterococos, Pseudomonas aeruginosa, valores de cor e turbidez. O perfil dos consumidores de água envasada, a percepção sobre a qualidade da água e os motivos para escolha dessa água foram obtidos por intermédio de entrevistas, empregando a estratégia da análise de conteúdo. A partir dos resultados encontrados foi constatado que as águas envasadas comercializadas no município de Viçosa (MG) apresentaram, em algum momento, contagem de microrganismos em valores superiores aos recomendados pela legislação. Já no estudo qualitativo sobre a percepção dos consumidores de água envasada foi possível perceber que a escolha para o consumo de água envasada está relacionada menos ao sentido de proteção da saúde e mais à disseminação de uma prática social, consolidada e legitimada no cotidiano.Palavras-chave: água envasada; microbiologia; percepção social. AbstractThe objective of this study was to characterize the microbiological and physical quality of mineral bottled water commercialized in Viçosa's city, Minas Gerais' State, and understand the perceptions related to its consumption. Samples of four brands of bottled water, in gallons of 20 liters, were analyzed for microbial (Escherichia coli, total coliforms, enterococci, Pseudomonas aeruginosa) and physical (color and turbidity) characterization. In addition, bottled water's consumers were interviewed to identity the perceptions concerning water quality and the reasons for choosing this water; these data were analyzed using content analysis strategy. The results showed that bottled water commercialized in Viçosa's city had, at some point, microorganisms counting higher than those recommended by Brazilian's regulation. The results concerning the qualitative study showed that the choice for bottled water consumption is less related to the sense of health protection than to a social practice, consolidated and legitimated in everyday.

“…The ozone in its gaseous or aqueous phases is effective against the majority of microorganisms tested by numerous research groups (2,4,5,6,26). Low concentrations and shortterm contact are enough to inactivate bacteria, mold yeast, protozoa algae and fungi (10,11,12,20).…”

The ozone is effective against most microorganisms due to its high oxidant power. Low concentrations and short-term contact are sufficient to inactivate bacteria, mold, yeast, parasites, seaweeds, protozoa and fungi. Microsporum canis is an important agent of dermatophitosis in human and animal. The aim of the current study was to assess the efficacy of ozonized oil over Microsporum canis in rabbits. Eighteen male New Zealand white rabbits, weight ranging from 2 to 3.2 kg were depilated in the cranial dorso-lateral and right caudal, and cranial and left caudal regions. The regions were inoculated with Microsporum canis, excepting the right caudal region, and were denominated TM, O, OM and M, respectively. After seven days, the treatment of lesions in TM began with 0.12g of terbinaphine 1% cream; in OM and O with 0.12g of ozonized oil; all animals were treated once a day for 28 days. Region M was not treated. Material was collected from those regions for cultivation in Sabouraud agar at day 28 of treatment. In the evolution of the treatment with terbinaphine, of 14 contaminated regions with Microsporum canis ten evolved to cure.With the ozonized oil, of 15 contaminations, four were cured. Clinically, that is, the macroscopic evaluation of lesions showed improvement in the TM and OM treated regions. We can conclude that there was statistical evidence of the protection action of the oil against the dermatophyte.
