Type and morphology. E. coli is a Gram-negative, facultative anaerobic (that makes ATP by aerobic respiration if oxygen is present, but is capable of switching to fermentation or anaerobic respiration if oxygen is absent) and nonsporulating bacterium. Cells are typically rod-shaped, and are about 2.0 μm long and 0.25–1.0 μm in diameter, with a cell volume of 0.6–0.7 μm 3.

The bacterial strains used in this study are listed in Table 1. R. insidosa strain FC1138 was isolated from food contact surfaces in a fresh-cut processing plant (Liu et al., 2013). E. coli O157:H7 strain FS4052 is a derivative from the non-virulent strain CDC B6-914 that carries a stable plasmid expressing green fluorescent protein (pGFP) (Fratamico, Deng, Strobaugh, & Palumbo, 1997).

Yersinia enterocolitica. Yersinia enterocolitica is a Gram-negative, asporogenous, rod-shaped bacterium and a member of the Enterobacteriaceae family of Proteobacteria that causes a broad range of gastrointestinal syndromes ranging from acute enteritis and enterocolitis to mesenteric lymphadenitis ().

They block enzymes and can cause bacteria to have irregularly shaped membranes, producing results ranging from inhibited growth to cell death. [email protected] NPs were highly effective against Escherichia.

Medical Microbiology begins with a review of the immune system, focusing on the body’s response to invading microorganisms. Bacteria are then covered, first with a series of chapters presenting the general concepts of bacterial microbiology and then with chapters detailing the major bacterial pathogenes of humans. Similar sections cover virology, mycology, and parasitology.

Genetics – Methods in genetics: Genetically diverse lines of organisms can be crossed in such a way to produce different combinations of alleles in one line. For example, parental lines are crossed, producing an F1 generation, which is then allowed to undergo random mating to produce offspring that have purebreeding genotypes (i.e., AA, bb, cc, or DD).
