Identification and phylogenetic analysis of Arsenophonus- and Photorhabdus-type bacteria from adult Hippoboscidae and Streblidae (Hippoboscoidea)

This is the first report of Arsenophonus- and Photorhabdus-type bacteria from Streblidae (bat flies) and Hippoboscidae (louse flies, keds). Strains were detected by means of polymerase chain reaction of 16S rDNA, and phylogenctic analysis determined the relationship of the obtained sequences to previously reported sequences in GenBank. Phylogenetic analysis by means of maximum parsimony revealed that all isolated Arsenophonus spp. 16S rDNA sequences formed a monophyletic sub-clade within other insect Arsellopholuls spp., while the Photorhabdus spp. sequences are part of a monophyletic clade including Photorhabdits spp., Xenorhabdus spp. and Proteus spp. (c) 2005 Elsevier Inc.
