The important quality criterion is absence of pathogens, a term which covers all disease-bearing bacteria. This criterion is usually determined by test for Eschericia coli, a species of bacteria so common in the gut that it is a reliable indicator of any pathogenic contamination.

The speed with which bacteria acquire resistance to antibiotics cautions restraint about prescribing them too frequently. Between 1983 and 1993, the percentage of patients receiving antibiotics rose from 1.4 to 45. During those years, researchers isolated Eschericia coli annually from patients, and tested the microbes for resistance to five types of fluroquinolones. Between 1983 and 1990, the antibiotics easily killed all 92 E. coli strains tested. However, in the interval from 1991 to 1993, 11 of 40 tested strains (28 percent) were resistant to all five drugs.

Bacteria such as Eschericia coli and Salmonella typhimurium swim by rotating flagella that lie on their surfaces (Figure 34.28). When the flagella rotate in a counterclockwise direction (viewed from outside the bacterium), the separate flagella form a bundle that very efficiently propels the bacterium through solution.

Heat stable enterotoxins are produced by Eschericia coli bacteria in the intestine and are responsible for acute diarrhea in humans and animals. They display a remarkable ability to retain their activity even at 100°C. 

Fig. 5.4 The OmpF porin from Eschericia coli is an integral membrane channel-forming protein which spans the outer membrane in Cram-negative bacteria. The structure of a monomer of the OmpF porin is shown. In total, 16 /3-bands are configured in the form of a cylinder and form the walls of a pore through which selective passage of ions takes place.

Tobramycin is an aminoglycoside antibiotic used to treat aerobic gram negative infections, such as Eschericia Coli, Enterobacter species, Pseudomonas species, or Staphylococcus Aureus. Aminoglycosides are notorious for their narrow therapeutic index and tobramycin is no exception. Prolonged exposure to aminoglycosides may...
