“…The overall S. aureus nares colonization rate of 22.0% noted in this study is higher than the only other investigation addressing nasal colonization among asymptomatic gravidas, noting a 4.0% S. aureus nasal colonization in 1978 [ 6 ]. Chen et al recently published S. aureus colonization rates from rectovaginal specimens collected for routine group B streptococcus (GBS) cultures done between 35–37 weeks of gestation and found that 17.1% of nearly 3000 women also had evidence for genital S. aureus colonization [ 13 ].…”

“…The carriage rate for S. aureus and MRSA among women presenting for obstetric care has not been recently evaluated. An evaluation published in 1978 of S. aureus nasal colonization among asymptomatic gravidas admitted to labor and delivery documented a 4% colonization rate [ 6 ]. The importance of S. aureus colonization as a marker for subsequent surgical-site infectious morbidity is well documented [ 7 , 8 ].…”

Objective. To determine colonization rates of Staphylococcus aureus given the potential for future intervention trials aimed at reducing surgical-site infectious morbidity, and to estimate methicillin-resistant Staphylococcus aureus (MRSA) rates in our patient population. Study design. Prospective pilot investigation comprising data from 104 gravidas admitted to an urban labor and delivery unit. All underwent anterior nares culture collection with a subset also undergoing vaginal culture collection. Results. Twenty-two percent of women were colonized in the anterior nares. Of the 28 women who had vaginal cultures collected, 4/28 (14.2%) demonstrated Staphylococcus aureus colonization. There was 82% concordance between the nares and vagina. Nine percent of isolates were MRSA strains. Overall, 2/96 (2.1%) of women were MRSA-colonized. Conclusions. Rates of Staphylococcus aureus colonization among gravidas entering labor and delivery are modest and consistent with the general population. MRSA rates among gravidas appear to be reassuringly low in this pilot study.

“…These two clinical entities were chosen because published reports demonstrate that S aureus is a major pathogen in these two outcomes. 11,29,50 Other potential burdensome infections of perinatal importance such as chorioamnionitis and/or postpartum endometritis were not included due to the lack of formal reports documenting MRSA as a direct cause of these intrauterine infections. In addition, a recent investigation by Thurman et al 51 (including pregnant women) documents a high rate of vulvar abscesses attributable to MRSA, thus highlighting the overall increasing burden.…”
