| Abstract |
Chiropteran mammals worldwide harbour trypanosomes (Euglenozoa: Kinetoplastea: Trypanosomatida) of the subgenus 'Schizotrypanum' in the classical sense. Latterly, these trypanosomes have been referred to as members of the 'Trypanosoma cruzi clade' as their phylogenetic relationships, structure and life cycle conform to T. cruzi, parasitising various terrestrial mammals as well as humans in Latin America. Little is known, however, about the trypanosome species in Asian bats. During a survey on Borrelia spp. in the Eastern bent-winged bat (Miniopterus fuliginosus) living in a cave in Wakayama Prefecture, Japan, incidental proliferation of trypanosomes was detected in two of 94 haemocultures. Squat or slender trypanosomes that proliferated in the cultures were 7.5-20.5 μm in length between both body ends and 1.0-3.8 μm in width with/without free flagella up to 14.5 μm (n = 29). The nucleotide sequences of the small subunit ribosomal RNA gene (SSU rDNA; 2176 bp), large subunit ribosomal RNA gene (1365 bp) and glycosomal glyceraldehyde-3-phosphate dehydrogenase gene (gGAPDH; 843 bp) of the present isolates were characterized to clarify their molecular phylogenetic position in T. cruzi-like trypanosomes. The newly obtained SSU rDNA and gGAPDH nucleotide sequences showed the highest identities with Brazilian and European isolates of Trypanosoma dionisii of the T. cruzi clade, ranging between 99.4 and 99.7% or between 95.6 and 99.3% identities, respectively. Although multiple T. dionisii isolates from the North and South American continents showed the closest molecular genetic relatedness to the present Far East isolates, only short SSU rDNA segments of the former isolates were deposited. Therefore, a definitive conclusion cannot be made until full nucleotide sequencing of at least the American isolates' SSU rDNA is available. This is the first confirmation of a Far East distribution of T. dionisii, demonstrating a wide geographical distribution of the species in the Eurasian and American continents with a limited nucleotide variation. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 18 January 2018.
All research outputs
#17,926,658
of 23,016,919 outputs
Outputs from Parasitology Research
#2,096
of 3,802 outputs
Outputs of similar age
#332,974
of 473,640 outputs
Outputs of similar age from Parasitology Research
#51
of 94 outputs
Altmetric has tracked 23,016,919 research outputs across all sources so far. This one is in the 19th percentile – i.e., 19% of other outputs scored the same or lower than it.
So far Altmetric has tracked 3,802 research outputs from this source. They receive a mean Attention Score of 2.7. This one is in the 37th percentile – i.e., 37% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 473,640 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 25th percentile – i.e., 25% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 94 others from the same source and published within six weeks on either side of this one. This one is in the 35th percentile – i.e., 35% of its contemporaries scored the same or lower than it.
