It is normal to identify low numbers of yeast cells in stool samples, says a clinical study published in Infectious Disease Reports. Some patients exposed to high levels of antibiotics exhibit high levels of yeast in stool samples but this finding does not appear to have any clinical significance.Continue Reading
High levels of yeast in the stool may be associated with inflammatory conditions, argues Carol A. Kumamoto in a review article published in Current Opinion in Microbiology. Kumamoto's opinion is based on the fact many patients suffering from gastrointestinal diseases such as Crohn's disease may have increased yeast in the stool. The author notes however that since many of these patients receive regular treatment with antibiotics, the level of yeast in the stool may be a side effect of the antibiotics.
Stool is tested for pathogenic organisms in cases of diarrhea that continue for several days, says the American Association for Clinical Chemistry. The test distinguishes between disease-causing organisms and the many organisms that are normally found in stool. The bacteria, fungi and yeast that normally inhabit the gastrointestinal tract are called normal flora. Pathogenic organisms usually enter the digestive tract via contaminated foods and beverages. The most common organisms that cause diarrhea are salmonella, shigella, campylobacter, certain strains of Escherichia coli and Clostridium difficile.Learn more about Cells
In a laboratory setting, boiling chloroplasts essentially prevents the reduction of 2.6-dichlorophenol-indophenol (DPIP). This artificial electron acceptor is used in place of nicotinamide adenine dinucleotide phosphate (NADP+) to measure photosynthetic activity.Full Answer >
An infection with coccobacilli bacteria is caused by an upset in the balance between bacteria and yeast distribution in the vagina, reports MedHelp. A doctor needs to diagnose this condition, known as bacterial vaginosis, as there are a number of different bacteria that can be responsible for vaginal infections.Full Answer >
Yeasts are unicellular members of the fungi kingdom and include those commonly found in baking and brewer's yeast, which are of the species saccharomyces cerevisiae. A member of the fungi phylum ascomycota, S. cerevisiae is also known as a "true yeast" because it reproduces by budding. Yeasts are eukaryotic organisms that are unable to obtain their nutritional needs by photosynthesis and require a reduced form of carbon as a food source.Full Answer >
Common baker's yeast, also known scientifically as Saccharomyces cerevisiae, contains 16 chromosomes. This is in its haploid state, a stage of the fungal organism's life cycle in which it reproduces via budding, which is the most usual state for yeast.Full Answer >
