Abstract
Dichelobacter nodosus is an anaerobic bacterium with fastidious growth requirements that is the principal cause of footrot associated with lameness in sheep and goats. In India, D. nodosus serogroups B and E have been recorded as major causes of footrot. Here we report the draft genome sequence of a D. nodosus serogroup E strain (JKS-07) from a case of virulent footrot in India. The whole genome of the D. nodosus JKS-07 serogroup E was sequenced using an Illumina HiSeq 2500 platform and was annotated according to functional gene categories. De novo genome assembly and annotation were performed using Perl scripts developed in-house using the Nr/Nt and UniProt databases. The assembled genome is 1389350bp and contains 1301 genes. The genome has 45 tRNAs and 9 rRNAs. The draft genome sequence will provide insight into the various genes and regulators involved in D. nodosus growth and survival. Information on the genome of the D. nodosus serogroup E strain is important bearing in mind the fact that both serogroups B and E are associated with virulent footrot, either alone or frequently together. In order to develop an efficacious vaccine against virulent footrot, it is essential to know the serological diversity as well as the virulence status of the D. nodosus strains. Serogroups B and E are potential vaccine candidates to mitigate ovine footrot in India.
