Scientists studying the body’s natural defenses against bacterial infection have identified a nutrient — taurine — that helps the gut recall prior infections and kill invading bacteria, such as Klebsiella pneumoniae (Kpn). The finding could aid efforts seeking alternatives to antibiotics.
A remediation and public education effort at an abandoned battery recycling facility in Bangladesh eliminated most lead soil contamination, but levels of the toxic metal in children living near the site did not decrease nearly as much. The discrepancy reveals the scope of other lead exposure sources and the challenge they present to public health.
Salmonella enterica serovar Typhimurium bacteria (S. Typhimurium) commonly cause human gastroenteritis, inflammation of the lining of the intestines. The bacteria live inside the gut and can infect the epithelial cells that line its surface. Many studies have shown that Salmonella use a ‘run-and-tumble’ method of short swimming periods (runs) punctuated by tumbles when they randomly change direction, but how they move within the gut is not well understood.
Authors of a new article urge researchers who conduct host-pathogen studies to adopt vouchering practices and to collaborate with natural history museums to permanently archive host specimens, along with their tissue and microbiological samples.
Researchers have developed an infectious disease early warning system that includes areas lacking health clinics participating in infectious disease surveillance. The approach compensates for existing gaps to support better observation and prediction of the spread of an outbreak, including to areas remaining without surveillance.
Scientists have uncovered new evidence of the potential health risks of chemicals in tobacco and marijuana smoke.
(Columbia University’s Mailman School of Public Health) The Global Consortium on Climate and Health Education (GCCHE), an international forum for developing curricula related to the health impacts of climate change, has announced an expanded set of key competencies for students of public health, nursing, and medicine.
The current COVID-19 pandemic has caused a surge of interest in the study of infectious disease transmission, and how control measures could change the course of the pandemic. New research examines the history of recorded smallpox epidemics in London.
New research has shown that implementing point-of-care testing in hospitals to diagnose influenza can lead to better treatment and faster recovery for patients. The researchers are now calling for routine use of these tests to become standard for patients admitted with acute respiratory symptoms during the influenza season.
Researchers demonstrate in a new study that a phage-based inhalation delivery system for vaccines generates potent antibody responses in mice and non-human primates, without causing lung damage. The findings suggest that a safe and effective lung delivery system could one day be used for vaccines and therapeutics against respiratory diseases.
