Microbiologists Investigate How to Fight Opportunistic Pathogens
August 24th 2015The Department of Microbiology at Kazan Federal University is investigating factors which allow bacteria to persist in human body when exposed to high-strength antibiotics. The team is focused on Proteus, Morganella, Providencia, and Serratia genera, which all are identified as opportunistic microbes and thus are dangerous to individuals with weakened immune system.
New Study Makes Major Advance Toward More Effective, Long-Lasting Flu Vaccine
August 24th 2015Scientists from the Scripps Research Institute (TSRI) and the Janssen Pharmaceutical Companies of Johnson & Johnson have found a way to induce antibodies to fight a wide range of influenza subtypes-work that could one day eliminate the need for repeated seasonal flu shots.
Ebola Diaries: A Psychological Toll to Endure
August 24th 2015A WHO logistician, Francis Mulemba was first deployed to West Africa in March 2014 to respond to the fifth Ebola outbreak in his career. He took care of logistic and administrative tasks in Gueckedou, Guinea, the epicenter of the epidemic. Five months later, he was sent to Monrovia, Liberia, to support training of the national burial teams. He said that situation in Liberia was unlike any other Ebola outbreak he had experienced before.
The Challenge of Getting Children to Ebola Healthcare Centers in Sierra Leone
August 24th 2015Intense surveillance in Kambia, Sierra Leone, has revealed that around 75 percent of deaths have been occurring in children under 5. Even though Ebola transmission was halted in Kambia last month, mothers still are afraid of Ebola and don’t take their young children to health centers. World Health Organization (WHO) epidemiologists are countering misperceptions to get mothers and their children back to the health centers and lower childhood mortality rates.
Chestnut Leaves Yield Extract That Disarms Staph Bacteria
August 21st 2015Leaves of the European chestnut tree contain ingredients with the power to disarm dangerous staph bacteria without boosting its drug resistance, scientists have found. PLOS ONE is publishing the study of a chestnut leaf extract, rich in ursene and oleanene derivatives, that blocks Staphlococcus aureus virulence and pathogenesis without detectable resistance.
Immune System Helps Killer Cells When Infection is Present
August 21st 2015Scientists at the University of Bonn, together with colleagues from the U.S. and Japan, have shed light on an important immune mechanism. Their work shows how the body provides the important killer cells with a helper in the case of an infection. The study could point the way to better vaccines in the future. The work has been published in the renowned journal Cell.
The Benefits of Ready-to-Use Wipes
August 21st 2015The traditional towel-and-bucket method of environmental cleaning is being replaced in many hospitals by ready-to-use disinfectant wipes. These pre-soaked disposable wipes are increasingly used for the disinfection of near-patient surfaces to prevent the spread of microorganisms and the emergence of nosocomial infections. This report explores the benefits of ready-to-use wipes as well as reviews the key factors that impact wipes' efficacy.
A Little Goes a Long Way: Stemming Antibiotic Resistance by Using Less
August 21st 2015Prompt initiation of antibiotics to treat infections has been proven to reduce mortality and save countless lives. But evidence has shown that use of these drugs far exceeds what is clinically necessary, leading to patient harm, excess costs and an increase in antibiotic-resistant bacteria worldwide.
Cellphone Data Help Scientists Track Infectious Diseases
August 20th 2015Tracking mobile phone data is often associated with privacy issues, but these vast datasets could be the key to understanding how infectious diseases are spread seasonally, according to a study published in the Proceedings of the National Academy of Sciences.
Biologist Observes a Paradigm Shift in Multi-drug Resistance
August 20th 2015Bacteria are pretty wily creatures. Take for example, an organism such as Salmonella, which which are killed by antibiotics in lab tests, but can become highly resistant in the body. It is an example of what UC Santa Barbara biologist Michael Mahan refers to as the Trojan horse strategy. Identified through new research conducted by Mahan and his colleagues, the Trojan horse strategy may explain why antibiotics are ineffective in some patients despite lab tests that predict otherwise. The research findings appear in the journal EBioMedicine.
