The present results of investigations performed on fresh fecal samples from a healthy adult and subjects with acute leukemia cultured bacteriologically using both aerobic and anaerobic techniques have led to the following conclusions. 1) In studies on the intestinal bacterial flora of the subjects examined, obligate anaerobic bacteria rather than facultative anaerobes accounted for more than 99...

Modern consumers are interested in the use of non-chemical methods to control pathogens when heat sterilization is not an option. Such is the case with teewurst sausage, a raw spreadable sausage and a popular German commodity. Although Listeria was not found in teewurst, the optimal microbial growing conditions of teewurst coupled with the ubiquity of L. monocytogenes in nature, makes the possi...

BACKGROUND Alterations in the intestinal bacterial flora are believed to be contributing factors to many chronic inflammatory and degenerative diseases including rheumatic diseases. While microbiological fecal culture analysis is now increasingly used, little is known about the relationship of changes in intestinal flora, dietary patterns and clinical outcome in specific diseases. To clarify th...

Fifty bifidobacteria strains were isolated from fecal samples of allergic and age matched healthy infants. Allergic infants were found to have an adult type Bifidobacterium flora with high levels of Bifidobacterium adolescentis. Healthy infants had a typical infant Bifidobacterium flora with high levels of Bifidobacterium bifidum. These isolates were tested for their adhesive properties to huma...

objective the standard of hygiene in daily life and hospitals can be increased by the use of new antimicrobial fibers, which diminish the danger of pathogenic bacteria. in this study, the antimicrobial effect of special fibers on some staphylococcus isolates was investigated. materials and methods the antimicrobial effect of special type of fibers produced in isfahan poly acryl plant on three s...

this is the first report about adverse inhibitory effect of v-guard and e-guard gasoline additives against soil beneficial streptomyces. v-guard and e-guard gasoline additives are anti valve seat recession agents used in unleaded gas for old car engines in iran. they contaminate soil and groundwater by fuel leaks and spills. streptomyces are of the major contributors to the biological buffering...

To test the role of bacterial fractions released from intestinal flora during immunomodulation by antimicrobial agents, BALB/c mice were treated with the non-absorbable antibiotics polymyxin B or teicoplanin by the intragastric route. The composition of faecal microbiota and the capacity of spleen cells to proliferate in response to B-cell and T-cell mitogens were assessed at several times duri...

Non-immunological defence mechanisms represent an important line of intestinal defence in addition to humoral and cellular immunity. This review summarises the evidence for the role of the non-immunological defence system. Protective factors that have been amply documented are gastric juice, intestinal motility, and intestinal flora. Components of pancreatic juice, lysozyme, and epithelial cell...
