PCR procedures based on 16S rRNA gene sequences specific for 12 anaerobic
bacteria that predominate in the human intestinal tract were developed and
used for quantitative detection of these species in human (adult and baby)
feces and animal (rat, mouse, cat, dog, monkey, and rabbit) feces.
Fusobacterium prausnitzii, Peptostreptococcus productus, and Clostridium
clostridiiforme had high PCR titers (the maximum dilutions for positive PCR
results ranged from 10(-3) to 10(-8)) in all of the human and animal fecal
samples tested. Bacteroides thetaiotaomicron, Bacteroides vulgatus, and
Eubacterium limosum also showed higher PCR titers (10(-2) to 10(-6)) in
adult human feces. The other bacteria tested, including Escherichia coli,
Bifidobacterium adolescentis, Bifidobacterium longum, Lactobacillus
acidophilus, Eubacterium biforme, and Bacteroides distasonis, were either
at low PCR titers (less than 10(-2)) or not detected by PCR. The reported
PCR procedure including the fecal sample preparation method is simplified
and rapid and eliminates the DNA isolation steps.
