It is in the Alphaproteobacteria class, which is part of the Proteobacteria phylum.
are gram-negative alphaproteobacteria that are transmitted between the reservoir and mammal host by hematophagous insects (1).
pensylvanicus were affiliated with Alphaproteobacteria, Gammaproteobacteria, Bacilli, and Mollicutes (Lundgren et al.
However, we have noticed a significant difference between the pharynx and the rest of the GM with class Alphaproteobacteria being the dominant taxon (30%-44%) in the pharynx whereas the Epsilonproteiobacteria (96%-98%) in the remaining segments of the gut, respectively.
Alphaproteobacteria represent the most diverse class of proteobacteria found in both lesions and on unaffected surfaces.
The communities on unaffected carapaces were dominated by members of alphaproteobacteria with at least 5 species (a Thalassobacter sp.
Within the proteobacteria, betaproteobacteria were the dominant class in groundwater (40% of total), with a mix of beta- and alphaproteobacteria in the soil-water (Fig.

The Alphaproteobacteria and Gammaproteobacteria (strains CS-2, CS-3, CS-5, CS-6, and CS-9 in Table 1) have closest relatives in salty environments from Korea and Brazil.
In addition, QIIME revealed that abundance levels of alphaproteobacteria, gammaproteobacteria, and Bacteroidetes levels were elevated when comparing apparently healthy lobsters with diseased lobsters, whereas Flavobacteria (the class that includes Aquimarina spp.
On the basis of 16S rDNA sequence analysis, the isolated ARB were assigned to alphaproteobacteria (n = 4), betaproteobacteria (n = 1), and the Bacteroides-Cytophaga-Flexibacter group (n = 2).
