A recent study, performed in Chicago and Rabat, Morocco, found that a novel finger-prick test for infection with the parasite Toxoplasma gondii during pregnancy — and many other potential applications — is 100 percent sensitive and 100 percent specific for detecting the presence of this life-damaging microorganism.
The new outbreak of the deadly Ebola virus declared just last week in eastern Democratic Republic of Congo is believed to have claimed more than 30 victims so far, highlighting the continued urgency to find a way to stop the pathogen from killing the people it infects. A new study is shedding light on the role of specific proteins that trigger a mechanism allowing Ebola virus to enter cells to…
For the first time, researchers at University of California San Diego School of Medicine and Imperial College London, with international collaborators, have determined that Kawasaki disease (KD) can be accurately diagnosed on the basis of the pattern of host gene expression in whole blood. The finding could lead to a diagnostic blood test to distinguish KD from other infectious and inflammatory…
Monash University’s Biomedicine Discovery Institute (BDI) researchers have identified a new mechanism used by Henipaviruses in infection, and potential new targets for antivirals to treat them. Their findings may also apply to other dangerous viruses.
Beckman Coulter announced commercialization of its DxM MicroScan WalkAway system, a diagnostic solution for bacterial identification and antibiotic susceptibility testing for microbiology laboratories. The DxM MicroScan WalkAway system uses direct minimum inhibitory concentrations (MIC) for detection of antimicrobial resistance, offering greater confidence in results through gold-standard…
Scientists conducting the first comprehensive study of key immune system cells—collected from West African Ebola survivors— have made a surprising discovery that provides important clues to developing effective vaccines against the infection.
Novaerus, an Irish company specialising in non-chemical air disinfection using patented ultra-low energy plasma, announced the launch of the Defend 1050, a portable, easy to use device ideal for rapid disinfection and purification of the air in large spaces and high-risk situations such as operating theatres, ICUs, IVF labs, emergency and waiting rooms, and construction zones.
Imagine a pathogen that infects completely healthy people and can cause blindness in one day and flesh-eating infections, brain abscesses and death in just a few days. Now imagine that this pathogen is also resistant to all antibiotics.
Researcher have created an ingestible sensor to non-invasively monitor indicators of disease in the stomach and intestines.
More than two years after reports of skyrocketing Zika rates surfaced worldwide, questions still loom about this complicated virus. Professor of Biological Science Hengli Tang and his postdoctoral researcher Jianshe Lang from the Florida State University take a deep dive into the differences between Zika and the Dengue virus.
Medicines given to household pets to kill fleas and ticks might be effective for preventing outbreaks of malaria, Zika fever and other dangerous insect-borne diseases that infect millions of people worldwide, according to a new study led by scientists at Calibr, a non-profit drug discovery institute closely affiliated with Scripps Research and TropIQ Health Sciences, a Dutch social enterprise.
Australia's national science agency CSIRO has identified a new gene that plays a critical role in regulating the body's immune response to infection and disease.
Since 2013, a new strain of meningococcal bacteria has spread rapidly in Niger and Nigeria, leading to large-scale outbreaks of meningitis. Analysis of the genetic material shows that with just two gene mutations, harmless bacteria transform into a strain that could cause major epidemics in these two countries.
While treatments for HIV mean that the disease is no longer largely fatal, the world still lacks a true therapy that can eradicate the virus across a globally—and genetically different—population.
The first defense line of the body against virus infections is composed of so-called restriction factors. SAMHD1, one of such restriction factors, does not only play a role in the defense against viruses but also in the development of autoimmune disorders and cancer. The question of which effect SAMHD1 exertsin the cell is decided by addition or removal of phosphate groups.
Antimicrobial resistance is on the rise worldwide. This is becoming a problem for infectious diseases like tuberculosis as there are only a few active substances available to combat such diseases. Pharmacists at Martin Luther University Halle-Wittenberg (MLU) have now found a way to increase the efficacy of a common tuberculosis agent while, at the same time, reducing resistance to it. The…
Green blood is one of the most unusual characteristics in the animal kingdom, but it's the hallmark of a group of lizards in New Guinea. Prasinohaema are green-blooded skinks, or a type of lizard. The muscles, bones and tongues of these lizards appear bright, lime-green due to high levels of biliverdin, or a green bile pigment, which is toxic and causes jaundice. Surprisingly, these lizards…
A recently identified pig virus can readily find its way into laboratory-cultured cells of people and other species, a discovery that raises concerns about the potential for outbreaks that threaten human and animal health. Researchers at The Ohio State University and Utrecht University in the Netherlands collaborated to better understand the new virus and its potential reach. Their study, the…
Gram-negative pathogens are responsible for half of all healthcare-associated infections and their ability to resist traditional antibiotics makes them more dangerous for seriously ill patients in a healthcare setting. The need for new approaches to treat these pathogens is essential and there are a number of trials trying to find suitable answers. One of them is the RESTORE-IMI 1 pivotal Phase…
Anthrax, plague and tularemia are three potent agents terrorists would be likely to use in an attack, according to the Centers for Disease Control and Prevention. Each is highly and quickly lethal to humans. But there are no licensed vaccines for tularemia and plague, and although there is an anthrax vaccine, it requires a burdensome immunization schedule and has severe side effects. Now, a…
A Vanderbilt team took the next leap forward in using a little-known bacteria to stop the spread of deadly mosquito-borne viruses such as Zika and dengue. Wolbachia are bacteria that occur widely in insects and, once they do, inhibit certain pathogenic viruses the insects carry. The problem with using Wolbachia broadly to protect humans is that the bacteria do not normally occur in mosquitoes…
While specific data remains limited on a possible connection between online forums and sexually-transmitted infections (STIs), this has become an area of increased focus. The subject was, for example, aired in April by one of the UK’s leading experts in the field, during the 28th European Congress of Clinical Microbiology and Infectious Diseases (ECCMID), in Madrid. At the four-day event, Dr…
Experts at the 70th Annual Meeting of the German Society for Hygiene and Microbiology, held in Bochum, exchanged information on newly discovered resistances. ‘Specifically, resistance against a class of antibiotics that has, so far, always been viewed as a reserve appears to be developing more intensively than previously assumed,’ explained Professor Sören Gatermann, congress president and…
This platform enables you to perform high class molecular diagnostics at an unbelievable speed. All assay run times are as short as 15 to 30 minutes, depending on the sample material. The lyophilised reactions are shippable and storable at room temperature and ready to use, with a shelf life of 18 month. Due to the robustness of the polymerase you don’t need any DNA extraction. The…
Loreen Herwaldt doesn’t believe there is a ‘gold standard’ for infection prevention, but she knows there are common sense steps that hospitals can take to prevent disease outbreaks. ‘I don’t think there’s a gold standard, or a silver bullet, but more like standard operating procedures,’ says Herwaldt, an infectious disease specialist at the University of Iowa, USA. ‘These are…
