Sentence examples for duration of host from inspiring English sources

Point estimates for parameters relating to the duration of host viraemia (ri and ni) were obtained by fitting Gamma distributions to published data.

To allow for a more general distribution for the extrinsic incubation (i.e. latent) period (EIP), the latent class is subdivided into a number of stages in a similar approach to that described above for the duration of host viraemia.

Selective advantage in this case is given by equation 4. One of the most significant parameters in epidemiology is the duration of host infection, D, which is taken to represent the period of time for which an infective is capable of transmission to susceptibles.

For the pathogens to survive in an Ixodes-host cycle, the duration of host infectivity must span the gap between seasons of tick activity [ 28].

A feature of schistosome epidemiology is that infection intensity and disease severity vary considerably between geographic areas and between individuals within the same region whether due to age and duration of exposure, host or parasite genetic background and/or host behaviour.

However, the majority of implantable biomaterials are intended for the duration of the host's lifetime.

Therefore, at optimum concentrations and duration of cytokines, host cell receptors targeted by bacteria may reach threshold levels required for bacterial invasion.

The findings from our studies described above [ 15, 16, 22] suggested that final outcome in patients with ARDS is related to the magnitude and duration of the host inflammatory response, and that intercurrent NIs might be an epiphenomenon of prolonged intense inflammation.
