Fat-soluble vitamin K is an essential component of the blood clotting process. Menaquinones are the naturally occurring form of vitamin K identified in bacteria. Lipid extracts were made from three bacteria originally isolated from the human neonatal gut and identified as Enterobacter agglomerans, Serratia marcescens and Enterococcus faecium . Following preparative thin layer chromatography (TLC), the lipid extracts were subjected to liquid chromatography-mass spectrometry (LC-MS) analysis. Peak analysis of the LC-MS data showed that the three bacteria produce various forms of menaquinone.

Comparing the gut flora of Irish breastfed and formula-fed neonates aged between birth and 6 weeks old. Microbial Ecology in Health and DiseaseJan 2005, Vol. 17, No. 3, Pages 163-168 (doi:10.1080/ 08910600500430664) Microbiological methods were used to specifically enumerate Lactobacilli sp., Bifidobacteria sp., Enterococci sp., Staphylococci sp., Bacteroides sp., Clostridia sp. and coliforms present in the gut. The data indicated major trends present, including the fact that Bifidobacteria sp. and Lactobacilli sp. were more prevalent in the gut flora of breast fed neonates whereas E.coli and Enterococci sp. were more prevalent in the gut flora of formula fed neonates. The higher prevalence of Bifidobacteria and Lactobacilli, which are often incorporated into probiotic foods, in Irish breast fed neonates thus re-enforces the advantages of breastfeeding over formula feeding.
