Candidatus Arsenophonus arthropodicus is a Gram-negative and intracellular secondary (S) endosymbiont that belongs to the genus Arsenophonus.[1] This bacterium is found in the Hippoboscid louse fly, Pseudolynchia canariensis.[1] S-endosymbionts are commonly found in distinct tissues.[1] Strains of recovered Arsenophonus found in arthropods share 99% sequence identification in the 16S rRNA gene across all species.[1] Arsenophonus-host interactions involve parasitism and mutualism, including a popular mechanism of "male-killing" found commonly in a related species, Arsenophonus nasoniae.[2][3] This species is considered "Ca. A. arthropodicus" due it being as of yet uncultured.[4]
Isolation and genome identification[edit]
Isolation[edit]
Amplified 16S rRNA gene sequences of Phoenix canariensis pupal DNA showed Arsenophonus detection in hemocytes, gut, fat body, and reproductive tissues indicating distribution of bacterium throughout hosts tissues.[1] Lab cultured bacteria found in these tissues show extracellular and intracellular attachment indicating Ca. A. arthropodicus can initiate intracellular infection in the host cells in vitro.[1]
A primary culture of P. canariensis pupae was used to enrich Ca. A. arthropodicus through Gram-positive inhibitor vancomycin and Gram-negative sensitive antibacterial cationic peptides.[1] Ancestral species identification also provides insight into Arsenophonus being a monophyletic clade.[5]
Genome identification[edit]
Contents of the Ca. A. arthropodicus genome are a single chromosome and multiple extrachromosomal elements.[1] Through the use of restriction enzymes Notl and Ascl the approximate chromosome size is 3.51 Mbp.[1] Two species were identified from enrichments based on the behavior of extrachromosomal DNA under alkaline lysis, restriction enzymes, and agarose gel electrophoresis .[1]
