Genetic study uncovers fungal sex secrets, which shed light on candidiasis

Fri, 15 Dec 2017 00:00:00 EST

Nanoparticles as a solution against antibiotic resistance?

Fri, 15 Dec 2017 00:00:00 EST

(Friedrich-Schiller-Universitaet Jena) Scientists of the Friedrich Schiller University Jena, Germany succeeded in developing an efficient method to treat mucoviscidosis. Crucial are nanoparticles that transport the antibiotics more efficiently to their destination. First of all, the active particles need to have a certain size to be able to reach the deeper airways and not to bounce off somewhere else before. Ultimately, they have to penetrate the thick layer of mucus on the airways as well as the lower layers of the bacteria biofilm.

Thu, 14 Dec 2017 00:00:00 EST

(PLOS) In the past decade, the first cases of respiratory tract infection caused by bat-borne Pteropine ortheovirus (PRV) have been reporting in humans. To help shed light on the clinical course of PRV infection, researchers reporting in PLOS Neglected Tropical Diseases have now used a mouse model of the infection to study its virulence, pathology and pathogenesis.



Lactic acid bacteria can protect against Influenza A virus, study finds

Wed, 13 Dec 2017 00:00:00 EST

(Georgia State University) Lactic acid bacteria, commonly used as probiotics to improve digestive health, can offer protection against different subtypes of influenza A virus, resulting in reduced weight loss after virus infection and lower amounts of virus replication in the lungs, according to a study led by Georgia State University.



Monkeys infected by mosquito bites further Zika virus research

Wed, 13 Dec 2017 00:00:00 EST

(University of Wisconsin-Madison) Monkeys who catch Zika virus through bites from infected mosquitoes develop infections that look like human Zika cases, and may help researchers understand the many ways Zika can be transmitted.



How well will the flu vaccine work this winter?

Wed, 13 Dec 2017 00:00:00 EST

(University of Texas Medical Branch at Galveston) Scientists from UTMB and Biomed Protection predicted which H3N2 variants would become 'vaccine resistant', and this prediction has been confirmed during the 2017 Australian flu season. The results published suggest that the current flu vaccine will work better during the 2018 US flu season than the 2017 Australian flu season.



Lyme study uses drug discovery methods that have fueled cancer breakthroughs

Wed, 13 Dec 2017 00:00:00 EST

(Duke University Medical Center) Researchers at Duke Health are working to expand the medical toolkit for treating Lyme disease by identifying vulnerable areas of disease-causing bacteria that could lead to innovative therapies.



Study: Lyme bacteria survive 28-day course of antibiotics months after infection

Wed, 13 Dec 2017 00:00:00 EST

(Tulane University) Lyme bacteria can survive a 28-day course of antibiotic treatment four months following infection by tick bite, according to a new study using a primate model for the disease. Despite testing negative for Lyme disease, some subjects were infected with Lyme bacteria in heart, brain and other organs.



Chimpanzee deaths in Uganda pinned on human cold virus

Wed, 13 Dec 2017 00:00:00 EST

(University of Wisconsin-Madison) In the wild, chimpanzees face any number of dire threats, ranging from poachers to predators to deforestation. That's why scientists, investigating an outbreak of respiratory disease in a community of wild chimpanzees in Uganda's Kibale National Park, were surprised and dismayed to discover that a human 'common cold' virus known as rhinovirus C was killing healthy chimps.

How do bacteria adapt?

Wed, 13 Dec 2017 00:00:00 EST

(Technical University of Munich (TUM)) A fundamental prerequisite for life on earth is the ability of living organisms to adapt to changing environmental conditions. Physicists at the Technical University of Munich (TUM) and the University of California San Diego (UCSD) have now determined that the regulation mechanisms used by bacteria to adapt to different environments are based on a global control process that can be described in a single equation.

(McGill University Health Centre) Believe it or not, a tropical blood parasite native to Latin America could be harmful to Canadians. Infectious diseases like malaria or Zika may have dominated recent headlines but Chagas -- the 'Kissing Bug' disease -- is in the spotlight following the publication of a new case study in the Canadian Medical Association Journal. Experts from Winnipeg and Montreal warn natives of Latin America and their offspring are at risk of contracting Chagas disease.
