Veillonella

(vā'yō-nel'ă),
A genus of nonmotile, nonsporeforming, anaerobic bacteria (family Veillonellaceae) containing small (0.3-0.5 mcm in diameter), gram-negative cocci which occur as diplococci short chains and in masses. Carbon dioxide is required for growth, and carbohydrates are not fermented. These organisms are parasitic in the mouth and the intestinal and respiratory tracts of humans and other animals; they produce serologically specific endotoxins (lipopolysaccharides) that induce pyrogenicity and the Schwartzman phenomenon in rabbits; in humans, they have been associated with human bite infections and as a component of polymicrobial abscesses. The type species is Veillonella parvula.

The most present genera are Streptococcus, followed by Veillonella, Prevotella, Fusobacterium, and Rothia [17, 19].
The only differences found were in the relative abundance of aerobic and anaerobic, being the obese population, presenting a higher proportion of anaerobic genera, mostly Veillonella, Bulleidia, and Oribacterium.
In another study of the gut microbiota of sixteen 6-8year-old Caucasian children with T1DM, compared with those of the control group, the number of Enterobacter cloacae, Bacteroides, and Veillonella increased significantly, the number of Actinomyces, Firmicutes, Bifidobacterium, and Lactobacillus species decreased, and the ratio of Bacteroides to Firmicutes increased [18].

When using molecular techniques, the most common species were found as Streptococcus, Veillonella, Provetella and Actinomyces.
Data also suggest that smoking could alter the upper airway microbiome, resulting in enrichment for Veillonella .[sup][28],[32]
The investigation determined that the infectious agent was Veillonella and not F.
Nevertheless, the stomach most commonly found bacteria are Prevotella, Streptococcus, Veillonella and Rothia.
