Mohamed Sesay was once part of an eight-person team of laboratory technicians trained to test for Ebola virus. But as the outbreak exploded and more and more samples arrived, his team was overwhelmed. One by one his colleagues sickened and died. He too eventually fell ill but survived, and is the only member of his team left to tell the tale.
Tests for antibiotic resistance can take up to three days to come back from the lab, hindering doctors' ability to treat bacterial infections quickly. Now, researcher Justin Besant and his team at the University of Toronto have designed a small and simple chip to test for antibiotic resistance in just one hour, giving doctors a shot at picking the most effective antibiotic to treat potentially deadly infections. Their work was published this week in the international journal Lab on a Chip
By unlocking the secrets of a bizarre virus that survives in nearly boiling acid, scientists at the University of Virginia School of Medicine have found a blueprint for battling human disease using DNA clad in near-indestructible armor.
A recent study with Kansas State University researchers details vaccine development for two new strains of avian influenza that can be transmitted from poultry to humans. The strains have led to the culling of millions of commercial chickens and turkeys as well as the death of hundreds of people.
With Canadian government funding, medical scientists have created and demonstrated a new tool that could dramatically lower the tragic annual toll of 760,000 infants and children killed, and millions more stunted, due to severe diarrhea. Using an inexpensive innovation in specimen collection, the Canadian-led team diagnosed previously unrecognized pathogens that had caused the severe diarrhea of more than one-third of children in a group of southern Africa hospitals.
The Association for Professionals in Infection Control and Epidemiology (APIC) and Infection Prevention and Control (IPAC) Canada annual conferences are just around the corner. Industry leaders will come together to exchange knowledge and creative solutions toward our shared goal of reducing hospital-acquired infections (HAI) and associated costs – financial and beyond. Many types of technology and solutions will be presented to enhance every aspect of the infection preventionist role, including hand hygiene compliance monitoring.
Researchers with the Fralin Life Science Institute at Virginia Tech have identified a gene responsible for sex determination in mosquitoes that can transmit yellow fever, dengue, and chikungunya viruses. Only female mosquitoes bite because they need blood for developing eggs, and researchers believe that a higher ratio of males could reduce disease transmission.
Bacteria resistant to antibiotics are on the rise. There are different explanations for how resistances are transferred. Researchers from the Vetmeduni Vienna found phages in chicken meat that are able to transfer antimicrobial resistance to bacteria. Phages are viruses that exclusively infect bacteria. They can contribute to the spread of antimicrobial resistance. The findings may also be relevant for clinical settings. The study was published in the journal Applied and Environmental Microbiology.
