in Eurasia," Infection, Genetics and Evolution, vol.
They can be responsible for infection and abscesses and can potentially transmit Lyme Disease, a particularly nasty condition, caused by a spirochaete
called Borrelia, that affects the heart and joints.
Lyme borreliosis, caused by the spirochaete
Borrelia burgdorferi sensu lato (s.l.), is a tickborne disease encountered primarily in the temperate regions of the Northern Hemisphere; in some countries, many thousands of cases are reported each year.
Six main phyla were found at varying proportions including 56% and 53% for Firmicutes, 33% and 32% for Bacteroidetes, 6% and 5% for Spirochaete
, 2% and 3% for Verrucomicrobia, 1% and 4% for Proteobacteria, and 1% and 1% for Fibrobacteres, in Mongolian horses and Thoroughbred horses, respectively (Figure 3A and 3B).

Por otro lado, en los filos con menor abundancia se encuentran Proteobacteria (0.71%), Bacteroidetes (0.19%), Fusobacteria (0.05%), DeinococcusThermus (0.04%), Cyanobacteria (0.04%), Acidobacteria (0.02%), Chloroflexi (0.02%), Gemmatimonadetes (0.01%), Tenericutes (0.01%), Planctomycetes (0.01%), Verrucomicrobia (0.01%), Spirochaetes
(0.003%), Nitrospirae (0.002%), Synergistetes (0.001%), Chlamydiae (0.0006%) (Tabla 6).
These microbiota are composed of representatives of many phyla, such as Firmicutes, Proteobacteria, Cyanobacteria, Spirochaetes
, Planctomycetes, Verrucomicrobia, Fusobacteria, Tenericutes and Bacteroidetes (Green & Barnes, 2010; Fernandez-Piquer et al., 2012), as well as those of a wide diversity of bacterial genera, including Vibrio, Pseudomonas, Acinetobacter, Photobacterium, Moraxella, Aeromonas, Micrococcus, and Bacillus (King et al., 2012; Wegner et al., 2013; Romalde et al., 2014; Trabal-Fernandez et al., 2014).
