MCF-7 Cells. MCF-7 is a breast cancer cell line isolated in 1970 from a 69-year-old White woman. [1] MCF-7 is the acronym of Michigan Cancer Foundation-7, referring to the institute in Detroit where the cell line was established in 1973 by Herbert Soule and co-workers. [2]
Methanobrevibacter smithii is the predominant methanogenic archaeon in the microbiota of the human gut. [1] M. smithii has a coccobacillus shape.It plays an important role in the efficient digestion of polysaccharides (complex sugars) by consuming the end products of bacterial fermentation (H 2, CO 2, acetate, and formate). [2]
Other stool tests involve the detection of antibiotic resistance as to guide appropriate therapy, e.g. Clarithromycin resistance of Helicobacter pylori represents a major challenge in eradication therapy but the responsible bacterial genomic markers can be detected in stool using PCR technology and thus can guide the prescription of the ...
Spiral bacteria are another major bacterial cell morphology. [2] [30] [31] [32] Spiral bacteria can be sub-classified as spirilla, spirochetes, or vibrios based on the number of twists per cell, cell thickness, cell flexibility, and motility. [33] Bacteria are known to evolve specific traits to survive in their ideal environment. [34]
The test is fast and can be performed in a doctor's office. A patient must not be receiving antibiotics. At least half a milliliter of feces is collected, and a strip of nitrazine paper is dipped in the sample and compared against a color scale. A pH of less than 5.5 indicates an acidic sample. [5]
Pseudescherichia vulneris is a Gram-negative bacterial species. P. vulneris is a fermentative, oxidase-negative, motile rod, which holds characteristics of the family Enterobacteraceae. This bacterium can colonize in the respiratory tract, genital tract, stool, and urinary tract.
Vibrio spp. are facultative anaerobes that test positive for oxidase and do not form spores. [4] [5] All members of the genus are motile. They are able to have polar or lateral flagellum with or without sheaths. [4] [6] Vibrio species typically possess two chromosomes, which is unusual for bacteria.
By growing and counting colonies of fecal coliform bacteria from a sample of water, the amount of bacteria originally present can be determined. Membrane filtration is the method of choice for the analysis of fecal coliforms in water. Samples to be tested are passed through a filter of particular pore size (generally 0.45 micrometre). The ...
