FIG 7  .

S. aureus UAMS-1 dissemination following influenza A virus coinfection. Each symbol represents the CFU recovered from a tissue sample from an individual mouse. The closed points represent nasal tissue (NT), and the open symbols represent lung tissue (LT). The black circles show the results for control mice that received only intranasal bacteria, and the blue diamonds show the results for mice that were colonized and coinfected with influenza virus 48 h later. The dashed line indicates the limit of CFU detection. Data presented are cumulative data from four independent replicate experiments. Values that are significantly different are indicated by bars and asterisks as follows: *, P = 0.0325; ***, P = 0.0002.
