Taking antibiotics today could leave antibiotic resistance genes in your gut for up to two years later, scientists find.
The U.S. Food and Drug Administration (FDA) approved ceftaroline fosamil, an injectable antibiotic to treat pneumonia and skin infections.
In the age of superbugs, this new injectable antibiotic will give clinicians another weapon to combat the growing battle against the often deadly, drug resistant bacteria.
Forest Laboratories' IV antibiotic Teflaro will interfere with the bacterial cell wall. The agency said in a news release that the drug will treat the following infections:
- methicillin-resistant Staphylococcus aureus (MRSA)
- community acquired bacterial pneumonia (CAMP)
- acute bacterial skin and skin structure infections (ABSSSI)
While it's important to have new antibiotics to treat the multi-drug resistant strains of pathogenic bacteria, scientists are looking more closely at the destruction antibiotic treatment has on a patient's normal gut flora.
As it turns out, the antibiotics you take today can have long-term consequences on your stomach.
Scientists found that patients taking antibiotics had high levels of antibiotic-resistant genes in their gut after a week off the treatment. While it was thought that the gut would take a short time to restore itself after antibiotic treatment, scientists have found that's not really what happens.
Patients can harbor antibiotic resistant genes a couple years after taking antibiotics - even if the patient never pops another antibiotic pill again.
Dr Cecilia Jernberg from the Swedish Institute for Infectious Disease Control published the study in the journal Microbiology, which officially comes out on November 3.
"The long-term presence of resistance genes in human gut bacteria dramatically increases the probability of them being transferred to and exploited by harmful bacteria that pass through the gut," said Jernberg. "This could reduce the success of future antibiotic treatments and potentially lead to new strains of antibiotic-resistant bacteria."
While the issue of antibiotic resistance is a growing concern, there are certainly better administration guidelines that could be established to contain the situation or at least encourage more conservative use of antibiotics.
