Real-Time Polymerase Chain Reaction (PCR) Five molecular targets were assayed using real-time PCR including human waste biomarkers (Bacteroides
16S rRNA [Bacteroides HF183] [Bernhard & Field, 2000; Haugland et al., 2010] and Bacteroides
hypothetical human-specific protein [Bacteroides HumM2] [Shanks et al., 2009]) and animal waste biomarkers (mitochondrial cytochrome b of dog and deer hosts [Schill & Mathes, 2008] and the mitochondrial NADH dehydrogenase subunits 5 and 2 of cat and avian hosts [Caldwell & Levine, 2009]).
Other groups that are part of the normal human microbiota are the anaerobic bacteria Bacteroides
sp., Prevotella sp., and Porphyromonas sp.
The association of Bacteroides
the taiotaomicron and Methanobrevibacter smithii increased the metabolic activity of germ-free colonized mice.
The study was carried out on stools of breast-fed infants with different genetic risk of CD (low and high); it showed that high-risk infants had a higher prevalence of Bacteroides
vulgatus, whereas low-risk infants had higher population of B.
species were identified in samples 1, 5, 6, 15, 18, and 20.
(3) Historical but outmoded names include Bacteroides
corrodens and HB-1.
'The lower abundance of Bacteroides
among the C-section infants may be a contributing factor to the observed differences in the Th1-associated chemokines.'
fragilis group consists of species of obligate anaerobic bacteria that inhabit the human gut.
Organisms within the four phyla were further divided into the following genera: Citrobacter (22%), Enterobacter (19%), Parabacteroides (11%), Bacteroides
(15%), Clostridia (7%), Akkermansia (7%), Aeromonas (4%), Robinsoniella (4%), Dorea (4%), and unknown Clostridiales (7%) (Fig 1).
The most common pathogen isolated was Escherichia coli, followed by Bacteroides
marker found in Bacteroides
, another type of fecal bacteria.
