The Oka vaccine strain
was obtained from the commercial vaccine preparation Varivax[R] (Genbiotech, India; Batch no: 200704041 Date of Expiry: 20/10/ 08) and processed in parallel with the clinical strains
Lungs from animals infected with the contemporary flu strain
showed few, if any, of these effects.
To know the extent to which configurations and conditions show deviations from this, one needs to test a range of samples under different conditions to different strain
How to identify profitable strains
and market them are just two.
In reassortment, scientists inject fertilized chicken eggs with both a standard nonpathogenic influenza strain
known to grow well in eggs and the circulating strain
that carries the genes expressing the desired HA and NA protein subtypes.
The specimens were then aged under strain
for several different periods of time.
The new trial vaccine is specific to the H5N1 strain
of avian influenza, but can be easily and quickly adapted to protect against other strains
of the virus.
Together, the cyclic stress strain
curve and the strain
-life curve enable designers to account for local stress-strain
conditions at stress concentrations like fillets.
In these methods either the Fourier coefficients, or diffraction line profiles themselves are calculated using models for the strain
and size distributions in the specimens.
He went on to discuss how HIV strains
are defined on the basis of their tropism.
The DNA of 1 outbreak strain
, which infected as many as l0 people, was tested only once in this study.
A virulent, once-rare strain
has driven a string of recent outbreaks and is suspected to be responsible for much of the overall increase in the disease.
These instruments range from custom servohydraulic testers for high strain
rate experiments to electromechanical instruments.
