Vincent, Dickson, and Daniel solve last week's case study, present a new one, and reveal how secreted proteins from a helminth prevent diabetes in mice.
t's a battleground down there—in the soil where plants and bacteria dwell.
Even though beneficial root bacteria come to the rescue when a plant is being attacked by pathogens, there's a dark side to the relationship between the plant and its white knight. According to research reported by a U... Read More
Vincent and Dickson discuss the spread of P. knowlesi in Malaysia, and how Leishmania parasites protect the sandfly gut from bacterial infection.
An antimicrobial agent found in common household soaps, shampoos and toothpastes may be finding its way inside human noses where it promotes the colonization of Staphylococcus aureus bacteria and could predispose some people to infection. Researchers at the University of Michigan report their fi... Read More
If you're a pet-owner who kisses your dog on the mouth, you might want to think twice.
A new study in the journal Archives of Oral Biology suggests that it's possible for disease-causing oral bacteria to be exchanged between dogs and their owners.
Japanese researchers examined dental plaqu... Read More
ANYONE who walks in the woods will be familiar with witches’ brooms (pictured). Many trees sport these bushy tumours, which have a variety of causes. An important one is a group of bacteria called phytoplasma that are, in turn, carried from plant to plant by sap-sucking insects such as leafhoppe... Read More
Carl Woese, a biophysicist and evolutionary microbiologist whose discovery 35 years ago of a “third domain” of life in the vast realm of micro-organisms altered scientific understanding of evolution, died on Sunday at his home in Urbana, Ill. He was 84.
His death was announced by the Universi... Read More
A bacterial protein in common house dust may worsen allergic responses to indoor allergens, according to research conducted by the National Institutes of Health and Duke University. The finding is the first to document the presence of the protein flagellin in house dust, bolstering the link betw... Read More
