IN VITRO ACTIVITY OF PROPOLIS AGAINST BACTERIAL AND  YEAST PATHOGENS ISOLATED FROM HUMAN INFECTIONS
Provedor de dados: 79
Autores: FERNANDES Jr.,A.; SUGIZAKI,M.F.; FOGO,M.L.; FUNARI,S.R.C.; LOPES,C.A.M.
The in vitro activity of propolis against 118 Staphylococcus aureus, 108 Escherichia coli, 60 Salmonella typhimurium, 50 Candida albicans, 23 Candida parapsilosis, 19 Candida tropicalis and 14 Candida guilliermondii isolated from human infections was studied by the agar dilution method. Among the bacteria, the Gram-negative were the least susceptible organisms showing minimal inhibitory concentration (MIC) for 90% of the strains tested ranging from 22.5 mg/ml - 10,2% V/V to 23.1 mg/ml - 10.5% V/V. The MIC's for Candida ranged from 0.80 mg/ml to &amp;gt; 11 mg/ml (0.40% V/V to &amp;gt; 5.0% V/V), the strains of C. parapsilosis being the least susceptible. The relative order of susceptibility among all isolates, was: S.aureus &amp;gt; C. tropicalis &amp;gt;...

Methodology for testing natural compounds for determination of antifungal activity had been developed with adaptations. The most used are bioautography and agar diffusion with a complex and no defined media. In this study, different methods for determination of antifungal activity of natural products are discussed and the use of M27-A2 microdilution test from CLSI (Clinical and Laboratory Standards Institute, 2002), as general standard methodology for testing plant extracts activity is recommended.

Medium composition influence on Biotin and Riboflavin production by newly isolated Candida sp
Provedor de dados: 58
Autores: Suzuki,Gaby Tiemi; Macedo,Juliana Alves; Macedo,Gabriela Alves.
Complex B vitamins as Biotin and Riboflavin are required by living organisms, not only for growth but also for metabolite production, and the feed market classifies them as growth promoters. Since Brazil will soon be one of the world's biggest animal protein producers, feed production is a large consumer of vitamins and micronutrients. The industry requires 10 mg riboflavin/0.2 mg biotin per kilogram of feed; a ratio of 40 ~ 50:1. Although few studies have been conducted specifically on riboflavin production using factorial design and surface response method as an optimization strategy, it is a common practice in biotechnology with many research reports available. However, there are no reports on the use of statistical design for biotin production. This...

Mastite por leveduras em bovinos leiteiros do Sul do Estado de Minas Gerais, Brasil
Provedor de dados: 65
Autores: Costa,Geraldo Márcio da; Silva,Nivaldo da; Rosa,Carlos Augusto; Figueiredo,Henrique César Pereira de; Pereira,Ulisses de Pádua.
O objetivo deste trabalho foi estudar a freqüência de infecções intramamárias ocasionadas por leveduras a partir de amostras de leite (n=1710) coletadas em 40 rebanhos leiteiros do Estado de Minas Gerais. Cinqüenta e seis estirpes de leveduras do gênero Candida e uma linhagem de Trichosporon loubieri foram isoladas. Candida albicans foi a espécie dominante (28,1% das cepas), seguida por Candida parapsilosis (19,3%), Candida catenulata (14,0%), Candida glabrata (14,0%) e Candida tropicalis (8,8%). Infecções mistas foram detectadas em 29,8% das vacas levedura-positivas. Amostras positivas para leveduras foram predominantemente obtidas (84%) de vacas com mastite subclínica. A baixa taxa de isolamento de leveduras sugere que estes microrganismos não são...
