Aims:

 

Aim 1: Characterize the effect of spaceflight analogue culture on microbial pathogenesis related stress responses and in vitro host-pathogen interactions. Analysis will include microbial stress responses as well as colonization and viability following pathogen challenge of three-dimensional (3-D) tissue co-culture models containing immune cells.

 

Aim 2: Characterize the effect of spaceflight analogue culture on the virulence potential of pathogenic microorganisms. Changes in virulence will be assessed using a mouse model of infection. To reduce and refine the use of animals for virulence studies, the selection of microorganisms for Aim 2 will be based on a combination of microbial responses from Aim 1 and previously reported spaceflight and spaceflight analogue experimental data of similar microorganisms.
