NIH Investigates Multidrug-Resistant Bacterium Emerging in Community Settings
September 6, 2023
New “hypervirulent” strains of the bacterium Klebsiella pneumoniae have emerged in healthy people in community settings, prompting a National Institutes of Health research group to investigate how the human immune system defends against infection. After exposing the strains to components of the human immune system in a laboratory “test tube” setting, scientists found that some strains were more likely to survive in blood and serum than others, and that neutrophils (white blood cells) are more likely to ingest and kill some strains than others.

Probiotic Markedly Reduces S. aureus Colonization in Phase 2 Trial
January 17, 2023
A promising approach to control Staphylococcus aureus bacterial colonization in people—using a probiotic instead of antibiotics—was safe and highly effective in a Phase 2 clinical trial. The new study, reported in The Lancet Microbe, found that the probiotic Bacillus subtilis markedly reduced S. aureus colonization in trial participants without harming the gut microbiota, which includes bacteria that can benefit people.

NIH-Supported Clinical Trial of Phage Therapy for Cystic Fibrosis Begins
October 4, 2022
Enrollment has begun in an early-stage clinical trial evaluating bacteriophage therapy in adults with cystic fibrosis (CF) who carry Pseudomonas aeruginosa (P. aeruginosa) in their lungs. The trial is evaluating whether the bacteriophage, or “phage,” therapy is safe and able to reduce the amount of bacteria in the lungs of volunteers. The trial is being conducted by the Antibacterial Resistance Leadership Group (ARLG), funded by the National Institute of Allergy and Infectious Diseases.

World TB Day 2022—Invest to End TB. Save Lives
March 24, 2022
Today marks the 140th anniversary of the announcement by Dr. Robert Koch that tuberculosis (TB) is caused by the bacterium Mycobacterium tuberculosis. World TB Day is a reminder that this ancient disease remains a relentless killer. The National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, affirms its commitment to the 2022 World TB Day theme, Invest to End TB. Save Lives, by supporting and conducting wide-ranging research aimed at reducing the health and economic impacts of TB.
Trial of Existing Antibiotic for Treating Staphylococcus aureus Bacteremia Begins
April 27, 2021
A clinical trial to test the antibiotic dalbavancin for safety and efficacy in treating complicated Staphylococcus aureus (S. aureus) bacteremia has begun. The trial will enroll 200 adults hospitalized with complicated S. aureus infection at approximately 20 trial sites around the United States. The trial is being sponsored by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health.
