When bacteria carrying resistance to antibiotics ...

Dangerous scenario: Antibiotic resistance genes from GM foods are digested bacteria in the intestines during digestion. When bacteria carrying resistance genes to antibiotics buy strattera ever cause an infection, it would be very difficult for doctors to treat. So far, however, there is no real evidence that the genes of resistance to antibiotics in the GM plants are threatened. However, as a preventive measure, some experts say that the resistance genes to antibiotics should not be used. Over the past 15 years there have been numerous scientific studies on this topic. So far, nothing dangerous was found. The most important results of these studies are:


probability of successful transmission of genes bacteria is very low. According to experts, laboratory experiments are likely to place anywhere from 1:10,000,000,000,000 in 1:1,000,000,000,000,000,000,000,000,000. Resistance genes and antibiotics most frequently used, is distributed in the body that cause disease. Tests on the stool of people do not take antibiotics, showed that in 60 percent of cases, more than 10 percent of bacterial resistance was at least one type of antibiotic. Soil tests have confirmed that antibiotic-resistant bacteria, including kanamycin-resistant bacteria are widespread in nature. Even if the resistance genes from


were transferred to bacteria in some cases increase the number of antibiotic-resistant bacteria in the environment would be immeasurably small. Kanamycin now rarely prescribed in human medicine. still used to treat some infections, but because the resistance is so widespread, treatment, usually in combination with agents (beta-lactamase inhibitors), host of the impact resistance genes. When we eat fruits and vegetables we eat antibiotic-resistant microorganisms in the soil. It is not known negative consequences. Despite these considerations, some still believe that the markers of resistance to antibiotics not be used at all as a preventive measure for environmental and consumer protection. It is believed that if GM plants with antibiotic resistance genes are planted on a very large area, a rare case of transfer of genes in other organisms (


) can be significant. .
