Group 2 (saliva, tongue, tonsils, and posterior pharyngeal wall) demonstrated a decreased relative abundance of Firmicutes compared to Group 1 replaced by increased levels of four phyla: Bacteroidetes, Fusobacteria, Actinobacteria and the candidate phylum TM7, and with a predominance of Streptococcus (approximately 20%), followed by approximately equal abundance of the genera Veillonella, Prevotella
, Neisseria, Fusobacterium, Actinomyces and Leptotrichia
A diet that limited intestinal Prevotella
growth also protected the mutant mice from developing osteomyelitis.
Twelve percent of the women had Prevotella
species in their endometrium that were resistant to both ceftriaxone and doxycycline, but not metronidazole.
Gram-negative organisms--including Klebsiella spp, Prevotella
spp, and Escherichia coli--were less commonly isolated.
At the genus level, the abundance of Bacteroides was much greater in cases, whereas Prevotella
was much more abundant in controls.
1980]; b) KVLB-2 agar (kanamycin 75[micro]g/ml-vancomycin 2[micro]g/ ml blood) for the isolation of pigmented and non-pigmented Prevotella
spp, Porphyromonas spp and Bacteroides spp; c) TSBV (trypticase-soy-agar) supplemented with 5% serum 75 [micro]g/ml bacitracin and 5 [micro]g/ml vancomycin to quantify Aggregatibacter actinomycetemcomitans [Slots, 1982].
reported its antibacterial activity against Streptococcus mutans, Streptococcus sobrinus, Prevotella
intermedia and Porphyromonas gingivalis (Kim, J.
Abscess fluid cultures from drainage revealed Prevotella
intermedia, Haemophilus parainfluenzae and Streptococcus spp.
Recent studies have linked diet to two main types of bacteria: Bacteroides help break down fats and proteins, and Prevotella
tackle fiber and carbohydrates.
fragilis 81 (45%), Clostridium perfringens 23 (13%), Peptostreptococcus anaerobius 14 (8%) and Prevotella
melaninogenica 14 (8%) were analysed separately.

The types of gut microbiota (called enterotypes) can be classified into three large, clearly distinguishable groups: Bacteroides, Prevotella
