“…The bacterial communities of the spider samples were dominated by five types of endosymbionts, Wolbachia, Cardinium, Rickettsia, Spiroplasma, and Rickettsiella. The dominant OTUs (operational taxonomic units) from each of the five endosymbionts were analyzed, and the results showed that different spider species were usually dominated by special OTUs. …”

“…Moreover, the other frequently observed quartet sequence 5′-CGGC-3′ in the ori region was homologous to the mitochondrial signal sequence of replication initiation, while the comparison of quartet sequence composition in APMV/Rickettsia-genome showed significantly similar values, suggesting that APMV also conserves the mitochondrial replication system acquired from an ancestral genome of mitochondria during eukaryogenesis.…”

“…Furthermore, new tickborne rickettsial infections continue to be recognized in Europe such as tickborne lymphadenopathy identified in 1997 and caused by Rickettsia slovaca. Novel tickborne infectious diseases will continue to emerge worldwide for the foreseeable future and be a challenge to the health of human populations. …”
