These differences reflect the differences between control and fasted steers in several specific rumen microorganisms, including Anaerovibrio lipolytica (p<0.05), Eubacterium ruminantium (p<0.05), Prevotella
albensis (p<0.05), Prevotella
ruminicola (p<0.05), and Ruminobacter amylophilus (p<0.05).
immigration is associated with profound perturbations to the gut microbiome, including loss of diversity, loss of native strains, loss of fiber degradation capability, and shifts from Prevotella
dominance to Bacteroides dominance." These changes resulted in obese individuals and continues in second-generation immigrants born in the U.S.
A Chinese case of prevotella
intermedia and streptococcus constellatus intracranial mixed infection.
But those with relatively more Prevotella
lost seven more pounds of fat on the New Nordic Diet than on the average Danish diet.

When normal flora is disrupted, other bacteria such as Gardnerella vaginalis, Mycoplasma hominis, and Prevotella
bacteroides, to name just a few, can take over, resulting in an unpleasant odor, a watery discharge, and a lower pH.
Other butyrate-producing and mucin-degrading bacteria, such as Prevotella
and Akkermansia muciniphila, are decreased  while short-chain fatty acid- (SCFAs-) producing bacteria such as Klebsiella are increased.
Some members of the gram-negative community are strict anaerobes, including Fusobacterium, Porphyromonas, Prevotella
, Tannerella and Treponema.
At genus level, the predominant genera ranked by abundance(over 1% of themicrobiome)were Prevotella
genus which accounted for 17.2% of the sequences, followed by Bacillus (5.1%), Porphyromonas (3.6%), Streptococcus (3.5%), and Bacteroides (3.2%) as shown in Figure 4.
