Table 4: MSA and antibiotic testing results distinguishing sample numbers compared to student numbers. S. aureus samples were calculated based on 200 test samples from each group (international and domestic). S. aureus positive students was determined based on 100 test subjects per group for a total of 200 (100 per group). MRSA sample percentage was calculated based on S. aureus positive samples and MRSA positive students was calculated as a percentage of S. aureus positive students. It should be noted that one domestic student had two distinct MRSA isolates which resulted in more unique strains than students.
