Influenza Pandemic Vaccines: Spread Them Thin?
T he global spread of highly pathogenic H5N1 infl uenza through poultry fl ocks is driving a large research effort aimed at mitigating the worst effects of an eventual human pandemic. Mathematical models and computer simulations are being used to explore different policy options in infl uenza pandemic control (for examples, see [1–4]). In a new study published in PLoS Medicine, Riley, Wu, and L...
متن کاملNew high-temperature superconducting phase spread alloy thin films
We have prepared Gd,-IPrXBa,Cu,O,-, phase spread alloy thin films with well-defined variations in the concentration of Pr across a single substrate. Their Pr concentrations were independently determined from electrical resistivity and Auger electron spectroscopy measurements. The results from both methods are in good agreement with each other. Using this technique several high-temperature super...
متن کاملSpread and change in stress resistance of Shiga toxin-producing Escherichia coli O157 on fungal colonies
To elucidate the effect of fungal hyphae on the behaviour of Shiga toxin-producing Escherichia coli (STEC) O157, the spread and change in stress resistance of the bacterium were evaluated after coculture with 11 species of food-related fungi including fermentation starters. Spread distances of STEC O157 varied depending on the co-cultured fungal species, and the motile bacterial strain spread f...
متن کاملDestructive disinfection of infected brood prevents systemic disease spread in ant colonies
In social groups, infections have the potential to spread rapidly and cause disease outbreaks. Here, we show that in a social insect, the ant Lasius neglectus, the negative consequences of fungal infections (Metarhizium brunneum) can be mitigated by employing an efficient multicomponent behaviour, termed destructive disinfection, which prevents further spread of the disease through the colony. ...
متن کاملThe interaction of thin-film flow, bacterial swarming and cell differentiation in colonies of Serratia liquefaciens.
The rate of expansion of bacterial colonies of S. liquefaciens is investigated in terms of a mathematical model that combines biological as well as hydrodynamic processes. The relative importance of cell differentiation and production of an extracellular wetting agent to bacterial swarming is explored using a continuum representation. The model incorporates aspects of thin film flow with variab...
