Genome Size Determination and Coding Capacity of Sodalis glossinidius , an Enteric Symbiont of Tsetse Flies, as Revealed by Hybridization to Escherichia coli Gene Arrays

Abstract: Recent molecular characterization of various microbial genomes has revealed differences in genome size and coding capacity between obligate symbionts and intracellular pathogens versus free-living organisms. Multiple symbiotic microorganisms have evolved with tsetse fly, the vector of African trypanosomes, over long evolutionary times. Although these symbionts are indispensable for tsetse fecundity, the biochemical and molecular basis of their functional significance is unknown. Here, we report on the genomic … Show more

“…; Diptera, Glossinidae), and Sitophilus oryzae primary endosymbiont (SOPE), a symbiont with the rice weevil (Sitophilus oryzae; Coleoptera, Dryophthoridae). Both of these recently established symbionts (4,24) show no AϩT bias in several of their sequenced genes (2,24). Although their genomes, 2.0 Mb for Sodalis (2) and 3.0 Mb for SOPE (11), have been reduced in size in comparison to free-living relatives, they are significantly larger than those of obligates.…”

“…Microarrays have been shown to be helpful for quick detection of antibiotic resistance (24), determination of virulence and pathogenicity (5,16,17), species determination (6), genome comparison (1,2,8,18), and molecular epidemiological typing of strains (3,9). In addition, the microarray procedure was used successfully to analyze the deletions and amplification mutations commonly found in Salmonella mutagenicity assay strains (Ames test) (21).…”

“…Among nonpathogenic arthropod endosymbionts, some but not all species of Buchnera carry plasmids encoding proteins involved in the biosynthesis of amino acids that are deficient in the phloemsap diet of the host aphid (50). Genome sequencing of an obligate endosymbiont, Wigglesworthia glossinidia (2), and a secondary symbiont, Sodalis glossinidius (1,14), of blood-feeding tsetse flies (Diptera: Glossinidae) revealed the presence of plasmids of undefined biological significance. Within the Rickettsiales, a plasmid has been described only for R. felis isolate California 2, a rickettsial endosymbiont of fleas (32).…”
