Long-term treatment ANTIBIOTIC Damaging Good Bacteria

A new Stanford University study found, antibiotic treatment, especially for long-term or repeated, can be a negative effect on good bacteria that live in the stomach. This good bacteria to help various aspects of human nutrition, metabolism and immune response.

In the study, the researchers focused on antibiotics that are widely used, ciprofloxacin, prescribed for a condition caused by bacteria, including urine infection. During these experts suspect, ciprofloxacin only cause danger on the good bacteria in the body.

The researchers found more than 5,600 species and a different strain of bacteria in the feces of volunteers treated with ciprofloxacin. When drinking antibiotics, about 30% of the species and strain of the bacteria affected the means.

Antibiotic effect on the stomach bacteria that vary between individuals with one another. Two volunteers showed a sharp decrease in the type of bacteria. Studies also found, so treatment with antibiotics is completed, most stomach strain of the bacteria need time to 4 weeks to return to the level before treatment.

No volunteers reported signs - signs that problems associated with the stomach for fluctuations in population stomach bacteria. But the study indicates, the possibility of antibiotic treatment have effects that last long on the overall health without known. The findings published in the journal PLoSBiology online edition.
