| comparative electron microscopy of chorio-allantoic placental barrier in some indian chiroptera. | in the present study the comparative ultrastructure of the definitive chorio-allantoic placental barrier has been studied in considerable detail in six species of bats, representing six different families and both suborders of chiroptera, by electron microscopy, and these species illustrate different kinds of interhaemal membranes met with among bats. the definitive chorio-allantoic placenta of rousettus leschenaulti is haemodichorial, since the syncytiotrophoblast and cytotrophoblast layers are ... | 1990 | 2220288 |
| molecular phylogeny of mobatviruses (hantaviridae) in myanmar and vietnam. | the discovery of highly divergent lineages of hantaviruses (family hantaviridae) in shrews, moles, and bats of multiple species raises the possibility that non-rodent hosts may have played a significant role in their evolutionary history. to further investigate this prospect, total rna was extracted from rnalater®-preserved lung tissues of 277 bats (representing five families, 14 genera and 40 species), captured in myanmar and vietnam during 2013⁻2016. hantavirus rna was detected in two of 15 bl ... | 2019 | 30866403 |
| insectivorous bat reproduction and human cave visitation in cambodia: a perfect conservation storm? | cave roosting bats represent an important component of southeast asian bat diversity and are vulnerable to human disturbance during critical reproductive periods (pregnancy, lactation and weaning). because dramatic growth of cave tourism in recent decades has raised concerns about impacts on cave bats in the region, we assessed the reproductive phenology of two insectivorous species (hipposideros larvatus sensu lato and taphozous melanopogon) at three caves in cambodia for 23 months in 2014-2016 ... | 2018 | 29709036 |
| flying around in the genome: characterization of line-1 in chiroptera. | l1s are transposable elements that move by a copy-and-paste mechanism that continuously increases their copy number in the genome, such that each genome has a record of the l1 history in that host lineage. they make up about 20% of the genomes of eutherian mammals and have played a major role in shaping genome evolution. chiroptera has the lowest average genome size among mammalian orders and the only documented case of l1 extinction affecting an entire mammalian family. herein, l1 activity and ... | 2019 | 32095030 |
| first molecular investigation of haemosporidian parasites in thai bat species. | malaria parasites in the phylum apicomplexa (order: haemosporida) infect diverse vertebrates and invertebrate hosts. at least seven genera of haemosporidian parasites have been described to exclusively infect bats. most of these parasites remain enigmatic with a poorly known host range. here, we investigated 271 bats belonging to 21 species and seven families from six provinces of thailand. overall, 124 out of 271 bats (45.8%) were positive for haemosporidian parasites, while none had plasmodium ... | 2020 | 32904325 |
| epidemiology and molecular characterization of rotavirus a in fruit bats in bangladesh. | rotavirus a (rva) is the primary cause of acute dehydrating diarrhea in human and numerous animal species. animal-to-human interspecies transmission is one of the evolutionary mechanisms driving rotavirus strain diversity in humans. we screened fresh feces from 416 bats (201 pteropus medius, 165 rousettus leschenaultii and 50 taphozous melanopogon) for rva using rrt-pcr. we detected a prevalence of 7% (95% ci 3.5-10.8) and 2% (95% ci 0.4-5.2) in p. medius and r. leschenaultii, respectively. we d ... | 2020 | 32876756 |
| 'rigid' internal timing in the circadian rhythm of flight activity in a tropical bat. | the timing of the emergence activity of a colony of the bat taphozous melanopogon occupying a cave environment in madurai (lat. 9°58' n, long. 78°10' e) and consisting of approximately 150-180 animals of both sexes was studies at 10-day intervals for one year. even though the time of sunset during the eyar varied over a range of 41 min, the bats displayed an astonishingly 'rigid' time of emergence that was restricted to a narrow 'gate' of 16 min from 18:25 to 18:41 h. the timing of the terminati ... | 1977 | 28309094 |
