Because of the increasing importance of STAPHYLOCOCCUS AUREUS (SA), including methicillin-resistant SA (MRSA) in serious neonatal infections, we studied the contribution of perinatal maternal-infant transmission of SA to the colonization and infection of newborn infants. Cultures for SA, including MRSA, were obtained from nares and vagina of women in labor at term. Each mother's infant, if delivered vaginally, was cultured from nares and skin at delivery and again after 48 hours (at discharge). All MRSA and selected SA isolates were studied by pulsed field gel electrophoresis (PFGE). Infants were monitored after discharge for staphylococcal infection for 4 weeks. Of 304 women completing the study, 43 were colonized with SA, and 9/43 had MRSA. Of 252 evaluable infants, 25 were colonized with SA, and 9/25 had MRSA. Six of 252 mother-infant pairs were concordant for SA colonization, and one of these for MRSA. Isolates from five of these six infants were indistinguishable from their mother's isolates by PFGE, including the pair with MRSA. One SA-colonized infant and four noncolonized infants subsequently developed staphylococcal infections during the monitoring period. About 20% of SA isolates in this maternal population were MRSA. Perinatal maternal-infant transmission accounted for 20% of instances of perinatal colonization of infants with SA. Molecular confirmation of perinatal maternal-infant transmission of MRSA was first documented. In this population of term infants, most SA infections in the first 4 weeks of life appeared to result from colonization that occurred after discharge from the nursery.

About Me
- Pat O'Connor
- Am old enough to understand the difference between the Bay of Pigs - and roasting a pig at a epicurian feast. Been thru the hippy, yippie and yuppie years - always remaining who I am. Very much believe in "Sing your own song - weave your own tapestry" Am young enough to still know the thrill of new discoveries, the beauty of the evening, to celebrate the joy of another tommorow. Survived these many decades with a severe medical problems. Sorting out the maze of now having two lymphomas and all their nasty little companions, but I continue. Besides, being a simple iconoclastic eclectic, have been called many things. An incurable romanticist - with a strong touch of reality. Thinker, intellectual (God, how I hate that term) - been told I am a lion with the heart of the poet. Know how to wage war and conquer my foes - but would rather be known as one who brings hope and life. To bring hope into anothers life is the ultimate of joys. Life should be about bringing hope, peace, vision... a sense of purpose beyond yourself.
