ABSTRACT

The aim of this study was detect the presence of dermatophyte fungi on wild felids from screening centers. Samples were taken from 30 animals, assembled in two groups: "free-ranging" and "transitory captivity". The dermatophytes (Trichophyton genus), isolated from two felids (6.6%), both of the group "free-ranging".

ABSTRACT

In vitro tests could be a valuable tool for the evaluation of medicinal plants antimicrobial activity. Mentha arvensis of the Lamiaceae family is one of the most frequently traditional plants used in Brazil. Hydroalcoholic extracts of M. arvensis were analyzed for antimicrobial activity on Streptococcus mutans, Streptococcus sobrinus and Candida albicans. Three different assays (agar diffusion, broth macro- and micro-dilution methods) were used to evaluate antimicrobial activity. Although hydroalcoholic extracts of M. arvensis did not show any antibacterial effect, its antifungal activity against C. albicans was revealed. According to the micro-dilution broth assay, MIC of the hydroalcoholic extract from leaves of M. arvensis on Candida albicans strains ranged between 625 and 2500 mg mL-1. Results suggest that M. arvensis hydroalcoholic extract may be considered a potentially antifungal agent against C. albicans, and a possible item for human antibiotic therapy.  However, further biological tests on the plants efficacy and side-effects are necessary before its use on humans.

ABSTRACT

The consumption of homemade doce de leite, which is sold in street markets, is very common in the state of Rio Grande do Sul, Brazil. Generally, these products are not manufactured according to good hygiene guidelines, and may be a risk to consumers health. The aim of the present study was to analyze microbiologically samples of doce de leite commercialized in street markets in the city of Pelotas, Rio Grande do Sul State, according to the present legislation of Brazils National Health Surveillance Agency (Anvisa), and thus verify the sanitary conditions of this product. Samples of doce de leite were randomly acquired from street markets in Pelotas, Rio Grande do Sul State, Brazil. Among the 12 street markets registered in the Pelotas City Council, doce de leite samples were found in only five. The microbiological analyses were carried out according to document RDC n 12 (Jan. 12, 2001) from Brazils National Health Surveillance Agency (Anvisa). Based on the methodologies employed, no microbial pathogen isolates were detected in the investigated samples of doce de leite. According to the criteria established by document RDC n 12, it was concluded that none of the doce de leite samples revealed pathogenic bacterial contamination.


O consumo de doce de leite caseiro, vendido em feiras livres, é comum no Estado do Rio Grande do Sul. Geralmente, estes produtos não são fabricados em acordo com as boas normas de fabricação e podem constituir perigo à saúde do consumidor. O objetivo do presente estudo foi analisar, microbiologicamente, amostras de doce de leite comercializado nas feiras livres da cidade de Pelotas, Estado do Rio Grande do Sul, conforme legislação em vigor da Agência Nacional de Vigilância Sanitária Anvisa, e, dessa forma, verificar as condições sanitárias do produto em questão. Foram adquiridas, aleatoriamente, amostras de doce de leite de feiras livres existentes na cidade de Pelotas, Estado do Rio Grande do Sul, Brasil. Das 12 feiras cadastradas na prefeitura de Pelotas, em apenas cinco foram encontradas amostras de doce de leite. As análises microbiológicas foram realizadas conforme metodologias preconizadas pela Resolução RDC n 12 de 2 de janeiro de 2001 da Agência Nacional de Vigilância Sanitária Anvisa. Com base nas metodologias empregadas, não se obteve isolamento de microrganismos patogênicos nas amostras de doce de leite pesquisadas. De acordo com os critérios estabelecidos pelo documento RDC no 12 da Anvisa, concluiu-se que nenhuma das amostras de doce de leite revelou contaminação bacteriana patogênica.

ABSTRACT

Os ácidos bórico e acético são dois anti-sépticos de uso humano e animal que foram avaliados e comparados, no presentetrabalho, quanto às suas atividades frente a três isolados de Pseudomonas aeruginosa, provenientes de otite externa canina,através de duas técnicas in vitro de antibiograma, pour plate e ágar difusão. O ácido bórico demonstrou ter maior atividadecontra P. aeruginosa.
