Macroscopic lung pathology in swine influenza, MRSA, and dual-infected pigs. The pathology score represents the sum of lesion scores, graded by different lobes: right and left caudal (0–5), right and left cranial and middle (0–10), and accessory (0–5) lobes. Days after SIV infection are indicated on the X-axis, and average score on day of harvest is depicted on the Y-axis. Average lesion score is depicted for MRSA only (n = 4), SIV only (n = 4), and dual-infected animals (n = 4). Asterisk indicates a P value of <0.05 for MRSA compared with animals dual-infected on D4. Values represent mean with standard error.
