Medical research from the University of Cambridge and Harvard Medical School has found that a single dose of a common antibiotic, ampicillin, can effectively kill the disease-causing bacterium Pseudomonas aeruginosa.
The study, published in the journal Science, involved more than 3,000 people in a major urban area in India.
The findings may lead to better antibiotics for the world’s biggest health problems, including tuberculosis and malaria, the authors say.
The team of researchers examined a single gram of ampicillins antibiotic, the one commonly used by hospitals, and a range of other antibiotics, which are used by millions of people every year.
They found that ampicilli can kill bacteria in the intestine of the person who receives it.
The ampicins antibiotic is used in hospital equipment to treat infections caused by MRSA bacteria, which cause pneumonia and other illnesses in people.
They were surprised to find that the drug did so much more than other antibiotics.
In the majority of the cases they tested, the researchers found that the bacteria were able to survive after treatment with ampicillo antibiotics, but not the other antibiotics used by the people in the study.
This suggests that it is more effective than the other drugs at killing Pseudomassas bacteria, the team found.
In addition, the ampicilly antibiotic can kill Pseudobacterium bifidum bacteria, a common cause of pneumonia in the elderly.
Dr. G. N. Dhankar, one of the study’s authors and an expert in infectious disease at the Medical University of South Carolina in Columbia, South Carolina, said the findings should be of great interest to healthcare providers.
“If you can use a single antibiotic, that’s the best drug that you can,” he said.
“It is much safer than other drugs that are used to treat this particular bacteria.”
The research team was led by Dr. Nandini Sengupta of Harvard Medical College.
The work was funded by the National Institutes of Health.
