Kobayashi K, et al. - Experts examined the associations among surgical site infection (SSI) following spinal surgery, nasal methicillin-resistant staphylococcus aureus (MRSA) colonization, and wound drain culture results. As per findings, there was not a necessary relationship between MRSA carriers and MRSA infection but MRSA carriers were seen to be associated with a positive drain tip culture and SSI, which could be because of the endogenous skin bacteria. Hence, in patients with nasal MRSA colonization or bacteria detected in a drain tip culture, possible SSI ought to be considered.
