词条 | Non-motile bacteria |
释义 |
Though the lack of motility might be regarded a disadvantage, some non-motile bacteria possess structures that allow their attachment to eukaryotic cells, like GI mucousal cells.[4] Vancomycin resistant Enterococcus spp. are non-motile while vancomycin susceptible Enterococcus spp. Some genera have been divided based upon the presence or absence of motility. Motility is determined by using a motility medium. The ingredients include motility test medium, nutrient broth powder, NaCl and distilled water. An inoculating needle (not a loop) is used to insert the bacterial sample. The needle is inserted through the medium for a length of one inch. The media tube incubated at 380C. Bacteria that are motile grow away from the stab, and toward the sides and downward toward the bottom of the tube. Growth should be observed in 24 to 48 hours. With some species, the bacterium is inconsistent related to its motility.[5]References1. ^{{cite web|url=http://faculty.ccbcmd.edu/courses/bio141/labmanua/lab7/nonmotil.html|title=BIOL 230 Lab Manual: Nonmotile Bacteria in Motility Medium|website=faculty.ccbcmd.edu}} {{Bacteria classification}}{{Bacteria}}{{microorganisms}}{{Portal|Medicine}}{{bacteria-stub}}2. ^{{cite web|url=http://textbookofbacteriology.net/structure_2.html|title=Structure and Function of Bacterial Cells|first=Kenneth Todar, Madison,|last=WI|website=textbookofbacteriology.net}} 3. ^{{cite journal |vauthors=Bardy S, Ng S, Jarrell K |title=Prokaryotic motility structures|journal=Microbiology |volume=149 |issue=Pt 2 |pages=295–304 |year=2003|pmid = 12624192 |doi=10.1099/mic.0.25948-0}} 4. ^{{cite journal|url=https://wwwnc.cdc.gov/eid/article/5/2/99-0205_article|title=Enteropathogenic E. coli, Salmonella, and Shigella: Masters of Host Cell Cytoskeletal Exploitation|first=Danika|last=Goosney|publisher=|journal=Emerging Infectious Diseases|volume=5|issue=2|pages=216–223|doi=10.3201/eid0502.990205|pmid=10221873|pmc=2640686}} 5. ^{{cite journal|pmc=172872 | pmid=8665466 | volume=8 | issue=4 | title=Identification, classification, and clinical relevance of catalase-negative, gram-positive cocci, excluding the streptococci and enterococci | journal=Clin Microbiol Rev | pages=479–95 | last1 = Facklam | first1 = R | last2 = Elliott | first2 = JA}} 4 : Bacteria|Bacteriology|Domains (biology)|Microscopic organisms described by Antonie van Leeuwenhoek |
