Details

Key Concepts:

• The human GI tract contains a diverse and complex ecosystem of microbiota that can exert significant influence on health
• New molecular techniques now allow exploration of this ecosystem
• Molecular techniques solve many of the problems of traditional culture-based microbiology
• Molecular techniques significantly improve sensitivity and specificity in parasitology and bacteriology of fecal samples
• Molecular techniques allow for better understanding of microbiota balance which enhances treatment options and improves outcomes
