Colonic microbiota signatures across five northern European countries

Christophe Lay et al. Appl Environ Microbiol. 2005 Jul.

Abstract

The composition of the colonic microbiota of 91 northern Europeans was characterized by fluorescent in situ hybridization using 18 phylogenetic probes. On average 75% of the bacteria were identified, and large interindividual variations were observed. Clostridium coccoides and Clostridium leptum were the dominant groups (28.0% and 25.2%), followed by the Bacteroides (8.5%). According to principal component analysis, no significant grouping with respect to geographic origin, age, or gender was observed.

Score plot of the PCA analysis with focus on groupings of samples with respect to geographic origin using principal components PC1 and PC2. The score plot shows the clustering of different samples, and samples that lie close to each other are similar with respect to the measured variables. Conversely, samples that lie diametrically opposite to each other will be very different from each other.
