| molecular taxonomic position of the elephant schistosome, bivitellobilharzia nairi, newly discovered in sri lanka. | bivitellobilharzia nairi (mudaliar and ramanujachar, 1945) dutt and srivastava, 1955 was first recorded in india. a number of adult worm specimens of this schistosome species were recovered from a domestic elephant, which died in 1999 in sri lanka. this is the first report of this schistosome from sri lanka. in the present study, in order to clarify the phylogenetic relationship with other species of schistosomes, sequences from the second internal transcribed spacer (its2) of the ribosomal gene ... | 2004 | 14984837 |
| an approach to revealing blood fluke life cycles, taxonomy, and diversity: provision of key reference data including dna sequence from single life cycle stages. | revealing diversity among extant blood flukes, and the patterns of relationships among them, has been hindered by the difficulty of determining if specimens described from different life cycle stages, hosts, geographic localities, and times represent the same or different species. persistent collection of all available life cycle stages and provision of exact collection localities, host identification, reference dna sequences for the parasite, and voucher specimens eventually will provide the fr ... | 2006 | 16629320 |
| morphology and surface topography of the schistosome bivitellobilharzia nairi from the asian elephant (elephas maximus maximus) in sri lanka. | bivitellobilharzia nairi was first recorded from an indian elephant (elephas maximus) in berlin. infections with this parasite have become increasingly important in e. maximus maximus populations in sri lanka. the present work is the first morphological description of this schistosome from sri lanka. a number of adult worms were recovered from a dead asian elephant near the elephant orphanage, pinnawala, in sri lanka. the observed clinical features of the infected elephant included emaciation, s ... | 2013 | 22989615 |
| sharing schistosomes: the elephant schistosome bivitellobilharzia nairi also infects the greater one-horned rhinoceros (rhinoceros unicornis) in chitwan national park, nepal. | because the digenetic trematode fauna of nepal is poorly known, we began to search for schistosomes in and around chitwan national park (cnp) of southern nepal. both domestic and wild indian elephants (elephus maximus) are present, and we found one of two dung samples from wild elephants and 1 of 22 (4.5%) dung samples from domestic elephants to be positive for schistosome eggs. the morphology of the eggs and both cox1 and 28s sequences derived from the eggs/miracidia were consistent with bivite ... | 2014 | 23113960 |
