new genetic lineages, host associations and circulation pathways of neorickettsia endosymbionts of digeneans. | neorickettsia is a genus of intracellular bacteria endosymbiotic in digeneans that may also invade cells of vertebrates and are known to cause diseases of wildlife and humans. herein, we report results of screening for neorickettsia of an extensive collection of dna extracts from adult and larval digeneans obtained from various vertebrates and mollusks in the united states. seven isolates of neorickettsia were detected by pcr and sequenced targeting a 527 bp long region of 16s rrna. sequence com ... | 2012 | 22875676 |
rhinoclemmysnema n. g. and three new species of nematodes of the family atractidae (cosmocercoidea), with notes on the helminth fauna of rhinoclemmys pulcherrima (testudines: bataguridae) in costa rica. | rhinoclemmysnema n. g. and three new species of atractid nematodes, namely, atractis costaricaensis n. sp., orientatractis asymmetrica n. sp. and rhinoclemmysnema multilabiatum were recovered from the small and large intestine of rhinoclemmys pulcherrima, the painted wood turtle in the guanacaste conservation area, costa rica. the genera and three species are characterized by the features of the cephalic region and male tail. neopolystoma fentoni (conjuctival sac) and heronimus mollis (lungs) we ... | 2006 | 17125541 |
phylogenetic position of heronimus mollis (digenea): evidence from 18s ribosomal rna. | most (1918bp) of the nucleotide sequence of the 18s ribosomal rna gene of heronimus mollis was determined. we aligned this sequence with 18s rrna sequences from 7 other digeneans and an aspidobothrean. using these data we explored the phylogenetic position of h. mollis. no support was found for the hypothesis that h. mollis is the sister taxon of the remaining digeneans examined here; similarly, no support was found for the hypothesis that h. mollis is closely related to the paramphistomes. thes ... | 1993 | 8354603 |
