Two gems from the summary:
Workers with facial hair were less likely to be colonized with Staph- ylococcus aureus (41.2% vs 52.6%, P 1ā4 0.02) and meticillin-resistant coagulase-negative staphylococci (2.0% vs 7.0%, P 1ā4 0.01).
And,
Overall, colonization is similar in male healthcare workers with and without facial hair; however, certain bacterial species were more prevalent in workers without facial hair.
