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.
