Dietas altas en grasas y sus efectos sobre el intestino

El objetivo de esta revisión fue exponer el conocimiento actual sobre la relación existente entre dietas altas en grasa (DAG), alteraciones morfológicas de la mucosa intestinal, efectos inflamatorios y cáncer intestinal. Las DAG inicialmente producen aumento de la microbiota patógena, lo que reduce ...

Effect of Myracrodruon urundeuva and Qualea grandiflora extracts on viability and activity of microcosm biofilm and prevention of enamel demineralization in vitro

The objective of this study was to evaluate the antimicrobial and anti-caries effects of two plant extracts. The first chapter dealt with a review of the literature whose objective was to discuss the antimicrobial potential of Brazilian natural agents on the biofilm related to dental caries and gingiviti...

O impacto do lúpus eritematoso sistêmico juvenil na inflamação gengival: achados clínicos, imunológicos e microbiológicos

Os objetivos desse estudo foram avaliar a expressão de citocinas no soro e fluido gengival, a produção de arginina-peptidil-deiminase (anti-PPAD) e o perfil microbiológico de pacientes com lúpus eritematoso sistêmico juvenil (LESj) e comparar com indivíduos saudáveis sistemicamente. Como objetivo...

Antimicrobial effect of copper surfaces on bacteria isolated from poultry meat

Braz. j. microbiol; 49 (supl.1), 2018
Abstract Poultry meat is a food product that usually carries high rates of microbial contamination, including foodborne pathogens. The poultry industry has established different systems to minimize these hazards. In recent years, extensive literature has demonstrated the antimicrobial activity of differe...

Bioconversion of waste cooking oil glycerol from cabbage extract to lactic acid by Rhizopus microsporus

Braz. j. microbiol; 49 (supl.1), 2018
Abstract Glycerol from spent oil was processed by transesterification for biodiesel production. Although glycerol contains many types of impurities, it can be used as a C-source for lactic acid production by fungi, such as Rhizopus microsporus. In this study, we found that wild type R. microsporus (LTH23...

Survey on pathogenic Escherichia coli and Salmonella spp. in captive cockatiels (Nymphicus hollandicus)

Braz. j. microbiol; 49 (supl.1), 2018
Abstract We surveyed healthy captive cockatiels (Nymphicus hollandicus) for Escherichia coli and Salmonella spp. Cloacal swabs were collected from 94 cockatiels kept in commercial breeders, private residencies and pet shops in the cities of São Paulo/SP and Niterói/RJ (Brazil). Three strains of E. coli...

Cost-effective production of bacterial cellulose using acidic food industry by-products

Braz. j. microbiol; 49 (supl.1), 2018
Abstract To reduce the cost of obtaining bacterial cellulose, acidic by-products of the alcohol and dairy industries were used without any pretreatment or addition of other nitrogen sources. Studies have shown that the greatest accumulation of bacterial cellulose (6.19 g/L) occurs on wheat thin stillage ...

The use of Prevotella bryantii 3C5 for modulation of the ruminal environment in an ovine model

Braz. j. microbiol; 49 (supl.1), 2018
Abstract In the Southern Hemisphere, ruminants are mostly raised in grazing systems where animals consume forage and are supplemented with low amounts of concentrates. Concentrates are usually given separately and are rapidly ingested. This practice leads to changing rumen environment conditions during t...

Diversity and communities of culturable endophytic fungi from different tree peonies (geoherbs and non-geoherbs), and their biosynthetic potential analysis

Braz. j. microbiol; 49 (supl.1), 2018
Abstract To know more about the potential roles of endophytic fungi in the formation mechanism of Daodi medicinal material, diversity and communities of culturable endophytic fungi in three types of tree peonies were investigated. Endophytic fungi of three types of tree peonies were isolated and identifi...

Dynamics and diversity of the bacterial community during the spontaneous decay of açai (Euterpe oleracea) fruits

Braz. j. microbiol; 49 (supl.1), 2018
Abstract The biodiversity and evolution of the microbial community in açai fruits (AF) between three geographical origins and two spontaneous decay conditions were examined by applying culture-independent methods. Culture-independent methods based on 16S rRNA from fifteen samples revealed that Proteobac...
