Genome Sequence of Avirulent Riemerella anatipestifer Strain RA-SG

Abstract

Riemerella anatipestifer is a pathogenic bacterium that has spread all over the world and is associated with epizootic infections in waterfowl and other avian species. R. anatipestifer RA-SG is an avirulent strain, isolated from an infected duck in Guangdong province, China. The genome sequence of this species is presented herein.

A homolog of glyceraldehyde-3-phosphate dehydrogenase from Riemerella anatipestifer is an extracellular protein and exhibits biological activity

“…Among the known serotypes of R. anatipestifer, there are huge variations in the virulence between serotypes and between different strains even within the same serotype (Subramaniam et al, 2000). Although four genome sequences of R. anatipestifer of strains ATCC 11845 (Mavromatis et al, 2011), RA-GD (Yuan et al, 2011), RA-YM (Zhou et al, 2010), and RA-SG (Yuan et al, 2013) have been reported, little is known about the molecular basis of the pathogenicity of R. anatipestifer infection, and so far, few virulence factors have been characterized other than virulence-associated protein D (VapD) (Chang et al, 1998), CAMP cohemolysin (Crasta et al, 2002), and outer membrane protein A (OmpA) (Hu et al, 2011).…”

Evolution in action: dissemination of tet(X) into pathogenic microbiota

“…Three genomic sequences of R. anatipestifer , published (Yuan et al, 2011) or available as database entries (GenBank accession numbers CP003787 and CP004020), also carry chromosomally encoded genes similar to tet (X) (Figure 1). Interestingly, four other strains of R. anatipestifer , for which genome sequences are available (Mavromatis et al, 2011; Zhou et al, 2011; Wang et al, 2012; Yuan et al, 2013), have not yet acquired tet (X). No information regarding antibiotic use practices at sampling sites where R. anatipestifer strains have been isolated is available in the cited publications.…”

Genome Sequence of Avirulent Riemerella anatipestifer Strain RA-JLLY

“…A total of 4,199 bp containing 61 repeat sequences were detected in the genome. Similar to another avirulent R. anatipestifer , RA-SG, two credible clustered regularly interspaced short palindromic repeats (CRISPRs) and two possible CRISPRs were found ( 14 ). In addition, there is an 89-bp prophage sequence.…”
