| Este trabalho objetivou caracterizar fenotipicamente isolados de Escherichia coli a partir de amostras obtidas de mãos e narizes de manipuladores, de leite cru e de queijo Minas Frescal produzidos em um laticínio em Goiás, Brasil, visando a estabelecer uma relação de contaminação entre o manipulador e/ou a matéria-prima e o produto final. Foram coletadas 24 amostras de leite cru e de queijo Minas Frescal, 46 swabs de mãos e 46 de narizes dos manipuladores envolvidos na fabricação do queijo, no período entre março/2004 e fevereiro/2005. As 69 cepas isoladas foram submetidas ao teste de suscetibilidade a seis antimicrobianos (ampicilina, cefalotina, ciprofloxacina, gentamicina, sulfametoxazol trimetoprin e tetraciclina) e, a partir deste teste, foi possível... |

| The aim of the study was to analyze epidemiological and microbiological aspects of oral colonization by methicillin-resistant Staphylococcus of health care workers in a cancer hospital. Interview and saliva sampling were performed with 149 health care workers. Antimicrobial resistance was determined by disk diffusion and minimum inhibitory concentration. Polymerase Chain Reaction, Internal Transcribed Spacer-Polymerase Chain Reaction and Pulsed Field Gel Electrophoresis were performed for genotypic characterization of methicillin-resistant Staphylococcus. Risk factors were determined by logistic regression. Methicillin-resistant Staphylococcus colonization prevalence was 19.5%, denture wearing (p = 0.03), habit of nail biting (p = 0.04) and preparation and... |

| An attempt was made to evaluate microbiological quality of horticultural crops grown organically. Three species of vegetables were used, lettuce (Lactuva sativa), radish (Raphanus sativus) and spinach (Tetragonia expansa), grown organically, in fertile soil. Six different treatments were applied: mineral fertilizer, chicken, cow, and pig manure, chicken litter and cow manure, in association with a liquid foliar biofertilizer. These crops were handled according to correct agronomic practices for growing crops organically for commercial purposes. Samples were examined for the Most Probable Number (MPN/g/mL) of total and fecal coliforms and to detect the presence of Escherichia coli and Salmonella spp. All analyzed samples were considered acceptable for... |
