The Proteobacteria phylum dominated in pediveliger larvae with 82.97% of the OTUs; Alphaproteobacteria
and Gammaproteobacteria were the most dominant classes with 52.15 and 22.29%, respectively.
The family Anaplasmataceae (Rickettsiales; Alphaproteobacteria
) comprises bacteria that are able to invade and infect their vertebrate host's blood cells, bone marrow-derived phagocytic cells, and endothelial cells; these bacteria can also infect cells of insects, helminths, and arthropod reproductive tissues (1-3).
(2010)--during the processes of composting, the bacterial composition changed from Alphaproteobacteria
and Gammaproteobacteria to Bacteroidetes and Firmicutes.
The OTUs were assigned to the classes Alphaproteobacteria
(8 OTUs), Betaproteobacteria (2 OTUs) and Gammaproteobacteria (3 OTUs) (Table 2).
Bacteria of the genus Wolbachia are obligate intracellular Gram-negative bacteria belonging to the Alphaproteobacteria
class (Table 1) found into the cytoplasmic vacuoles inside the cells of their insects, isopods, mites, arachnids and nematodes hosts .
In total, six well-recognized classes (Gammaproteobacteria, Alphaproteobacteria
, Betaproteobacteria, Deltaproteobacteria, Epsilonproteobacteria, and Zetaproteobacteria) were observed, among which Gammaproteobacteria (31.70-42.23%) in the R-samples and Alphaproteobacteria
(22.13-25.40%) in the S-samples were the top two most abundant classes.
In general, the class level abundances of the 88 OTUs shared between the floodwaters from the vegetative and reproductive stages were very similar and were both dominated by Betaproteobacteria, Actinobacteria, and Alphaproteobacteria
(Figures 4(a) and 4(b)).
PCR product (20 [micro]l) was loaded onto 8% (w/v) polyacrylamide gels, 1 mm thick, in 1x TAE buffer (20 mM Tris-acetate, 0.5 mM EDTA; pH9), with a 40-65% urea and formamide denaturant gradient for the study of Alphaproteobacteria
, Betaproteobacteria, and Firmicutes, 45-75% for Actinobacteria, and 20-70% for the diazotrophic community.
Brucella is a genus of Gram-negative facultative intracellular bacteria that belongs to the class Alphaproteobacteria
. Currently, the genus consists of 10 species that are classified based on their host preferences .

Microorganismos pertenecientes a los grupos de Alphaproteobacteria
, Deltaproteobacteria, Gammaproteobacteria, Actinobacteria, Bacilli y Chroobacteria, entre otros, han sido encontrados en biopeliculas formadas sobre los electrodos de MFC alimentadas con sedimentos marinos (Vandecandelaere et al., 2010, Sokhee et al., 2014), indicando que en ambientes marinos existe una amplia diversidad de microorganismos capaces de formar biopeliculas sobre los electrodos de las MFC.
