An acid-fast pathogen; over one-third of the world's population is infected; caseous necrosis is a hallmark of disease; MDR, XDR, BCG, and DOTS apply to this organism. Mycobacterium tuberculosis The most common cause of non-nosocomial urinary tract infections, usually in women; also the cause of the life-threatening disease known as hemolytic uremic syndrome. Escherichia coli Brainpower Read More Causes a life-threatening disease in individuals experiencing crowded and stressful living...

3 advantages of being a small cell - greater nutrient exchange, faster growth rate, higher mutation accum rate 3 features euk/prok share - cytoplasmic membrane, cytoplasm, ribosomes 3 functions of pili - surface attachment, genetic exchange, and type IV motility 3 properties of all cells - metabolism, growth, evolution 3 types of flagella and what they look like - peritrichous (on all sides), polar (one on the end), lophotrichous (multiple on end) 4 properties of only some cells - differe...

true motility Correct Answer-directed motion of bacteria (energy expenditure by the cell) brownian movement Correct Answer-random back-and-forth jiggling motion due to collisions of water molecules with the cells (cells don't go anywhere)... results from kinetic energy of molecules around the cell flagella Correct Answer-long, whip-like structures that extend beyond the surface of the cell and glycocalyx and propel the cell through its environment. Composed of flagellin serovars Correc...
