The existance of these mutated pathogens, and others, are explained to a large degree by the overuse and misuse of antibiotics. Especially is this true in the wealthier countries like the U.S., where healthy chickens and cattle are routinely fed antibiotics, and both children and adults are routinely prescribed antibiotics for the common cold or flu. In the healthy intestinal tract, dozens of different species of bacteria compete for nutrients. The ability of beneficial bacteria to maintain their positive balance of power over more harmful strains results in proper digestion and good health. Antibiotic use upsets this balance.
Antibiotics destroy both good and bad bacteria.
And it is almost impossible to destroy 100 percent of the pathogenic variety without long-term exposure to antibiotics, which many patients are unwilling to complete. Leaving behind even 1 percent or less of the harmful pathogens can have disastrous effects. In January of 1999, the FDA finally proposed limiting the use of antibiotics in animals and poultry. Report on Kidney Infection treatment failures. Much of the bacterial problem could be corrected by limiting antibiotic use and introducing beneficial forms of bacteria, yeast, and other natural, biological agents like garlic, into the system.
