A New Antibiotic For Fighting Disease-Causing Bacteria – Part 1 of 3
A New Antibiotic For Fighting Disease-Causing Bacteria. Laboratory researchers express they’ve discovered a new antibiotic that could prove valuable in fighting disease-causing bacteria that no longer counter to older, more frequently used drugs. The new antibiotic, teixobactin, has proven effective against a number of bacterial infections that have developed resistance to existing antibiotic drugs, researchers discharge in Jan 7, 2015 in the journal Nature. Researchers have used teixobactin to cure lab mice of MRSA (methicillin-resistant Staphylococcus aureus), a bacterial infection that sickens 80000 Americans and kills 11000 every year, according to the US Centers for Disease Control and Prevention (CDC).
The recent antibiotic also worked against the bacteria that causes pneumococcal pneumonia. Cell elegance tests also showed that the new drug effectively killed off drug-resistant strains of tuberculosis, anthrax and Clostridium difficile, a bacteria that causes life-threatening diarrhea and is associated with 250000 infections and 14000 deaths in the United States each year, according to the CDC. “My believe is that we will probably be in clinical trials three years from now,” said the study’s senior author, Kim Lewis, director of the Antimicrobial Discovery Center at Northeastern University in Boston.
Lewis said researchers are working to focus the new antibiotic and make it more effective for use in humans. Dr Ambreen Khalil, an infectious disease expert at Staten Island University Hospital in New York City, said teixobactin “has the potential of being a valuable addition to a limited number of antibiotic options that are currently available”. In particular, its effectiveness against MRSA “may end up to be critically significant”.
