Enterococcus spp. are Gram-positive lactic acid-producing bacteria found in the intestinal tracts of animals, like mammals, birds, and arthropods. Enterococcus spp. may cause oportunistic infections in vertebrate and invertebrate hosts. We report here the draft genome sequence of Enterococcus casseliflavus PAVET15 containing 3,722,480 bp, with 80 contigs, an N50 of 179,476 bp, and 41.93% GC content.
Enterococcal bacteria are found in several ecosystems and are useful as a fecal indicator for water quality and models of infection involving core and variable genetics elements that are not fully understood (1). Bacteria belonging to the genus Enterococcus are part of the microbiome of the cattle tick gut and may be found in female, male, and egg samples (2); additionally, several isolates of Enterococcus species bacteria from actual infections in engorged female ticks were obtained (3, 4).
Here, we present the draft genome sequence of Enterococcus casseliflavus PAVET15, obtained from an engorged female tick that showed symptoms of bacterial infection, such as the presence of an exudate at the genital orifice. This strain was grown overnight in Trypticase soy agar (TSA; Difco-BD) medium at 37°C, and the genomic DNA was extracted using the Wizard genomic purification kit (Promega). The sequence genome was obtained using 454 FLX pyrosequencing (Roche) by building DNA fragment libraries, according to the manufacturer’s recommendations. The genome was assembled using Newbler version 2.8, obtaining a total of 3,722,480 bp, 80 contigs, an N50 of 179,476 bp, average contig size of 46,531 bp, and largest contig of 349,357 bp. Genome sequence annotation was made by RAST [http://rast.nmpdr.org (5)]. The resulting genome comprises 3,594 coding proteins, 58 rRNAs, 50 tRNAs, and 41.93% GC content. We found 93.58% identity with E. casseliflavus and high synteny. For phylogenetic species differentiation, we used rpoB and tufA genes (data not shown). The virulent genes found in the strain PAVET15 could be relevant in the effort to find a biocontrol in the integral strategy to control the cattle tick.
