In Vitro Culture and Phylogenetic Analysis of "Candidatus Arsenophonus triatominarum," an Intracellular Bacterium from the Triatomine Bug, Triatoma infestans

Abstract: An intracellular symbiotic bacterium was isolated from the hemolymph of Triatorna infestans and cultured in an Aedes albopictus cell line. 16s ribosomal DNA sequence analysis revealed that the bacterium was a member of the y-3 subgroup of the class Proteobacteria, having 96.2% sequence identity with the most closely related bacterium, Arsenophonus nasoniae, the causative agent of the son-killer trait in the parasitoid wasp Nasonia vitripennis. These bacteria share morphological features and a common tissue dis… Show more

“…Artificial culture has been achieved only on insect cell lines (Hypsa and Dale, 1997;Dale et al, 2006). Different species of Arsenophonus from different hosts share 499% 16S rRNA gene sequence similarity, suggesting recent host acquisition (Dale et al, 2006).…”

“…Meanwhile, the molecular mechanisms underlying insect-microbe interactions are much less well understood, because most of these insect mutualistic symbionts are neither culturable nor genetically manipulatable. Recent studies have succeeded in the isolation of several facultative symbionts by using insect cell lines or axenic media (27,29,32,57,65,87,92), revolutionizing studies of insect endosymbiosis. The present article reviews the amazing diversity of bacterial endosymbiosis in insects, focusing on several model systems with culturable endosymbionts, which provides a new perspective regarding how intimate symbiotic associations may have evolved and how they are maintained within insects.…”

“…Condiciones de la reacción de PCR: el ADN bacteriano fue amplificado con los iniciadores: 16F (5'-GCTTAACACATGCAAG-3') y 16R (5'-ACGGGCAGTGTGTACAAGACC-3'), correspondientes a las posiciones 45 a 61 y 1406 a 1386, respectivamente, del gen codificante para el ARN ribosomal 16S de E. coli (13). La PCR se realizó en un volumen final de 50 ml, según lo descrito por Hypsa y Dale, (1997) y el producto de amplificación fue visualizado mediante electroforesis horizontal en geles de agarosa al 1% coloreados con bromuro de etidio (12).…”
