First Newborn's Aspirate Microbial Analysis and Lysozyme Activity Determination

Abstract

The aim of the present study was to investigate the presence of micro organisms in pregnant women's cervicovaginal regions just before delivery and in the first aspirate of the upper respiratory tract and the oral cavity in the newborns immediately after delivery. Microbial analyses of smears taken two hours postpartally from the throat, oral cavity, stomach and ear of neonates showed totally altered findings. Estimating lysozyme activity in the first newborn's aspirate, by the use of turbidimetry, according to the method of Prockop and Davidson (Lysozyme-Testomer-Boehringwerke), we found it's very high value. Our study in dicates that there is a strict relationship between microbiological substratum and lysozyme activity in the first newborn's aspirate. (Thai J Obstet Gynaecol 1993; 5: 87-90.)
