| molecular phylogeny of the superorder archonta. | the superorder archonta has been hypothesized to include primates, tree shrews, bats, and flying lemurs as descendants of a common ancestor. more recently, a diphyletic origin for bats has been proposed. to evaluate these hypotheses, the nucleotide sequence of the mitochondrial cytochrome oxidase subunit ii gene was determined from a bushbaby (galago senegalensis), flying lemur (cynocephalus variegatus), tree shrew (tupaia glis), spear-nosed bat (phyllostomus hastatus), rousette bat (rousettus l ... | 1991 | 1658802 |

| host specificity in bat ectoparasites: a natural experiment. | we undertook a field study to determine patterns of specialisation of ectoparasites in cave-dwelling bats in sri lanka. the hypothesis tested was that strict host specificity (monoxeny) could evolve through the development of differential species preferences through association with the different host groups. three species of cave-dwelling bats were chosen to represent a wide range of host-parasite associations (monoxeny to polyxeny), and both sympatric and allopatric roosting assemblages. of th ... | 2009 | 19232350 |
| structural and functional studies of leptins from hibernating and non-hibernating bats. | leptin, a 16-kda hormone produced by mature adipocytes, has been shown to regulate the hibernation of mammals. in this study, the leptin gene sequences of both hibernating (rhinolophus ferrumequinum) and non-hibernating (rousettus leschenaultii) bats were determined, and the leptin proteins from these two different species of bats were expressed in escherichia coli for the first time. results showed that the amino acid sequence of the leptin protein from hibernating bats had a lower degree of id ... | 2010 | 20394750 |
| contrasting genetic structure in two co-distributed species of old world fruit bat. | the fulvous fruit bat (rousettus leschenaulti) and the greater short-nosed fruit bat (cynopterus sphinx) are two abundant and widely co-distributed old world fruit bats in southeast and east asia. the former species forms large colonies in caves while the latter roots in small groups in trees. to test whether these differences in social organization and roosting ecology are associated with contrasting patterns of gene flow, we used mtdna and nuclear loci to characterize population genetic subdiv ... | 2010 | 21085717 |
| recent loss of vitamin c biosynthesis ability in bats. | the traditional assumption that bats cannot synthesize vitamin c (vc) has been challenged recently. we have previously shown that two old world bat species (rousettus leschenaultii and hipposideros armiger) have functional l-gulonolactone oxidase (gulo), an enzyme that catalyzes the last step of vc biosynthesis de novo. given the uncertainties surrounding when and how bats lost gulo function, exploration of gene evolutionary patterns is needed. we therefore sequenced gulo genes from 16 bat speci ... | 2011 | 22069493 |

| progressive pseudogenization: vitamin c synthesis and its loss in bats. | for the past 50 years, it was believed that all bats, like humans and guinea pigs, did not synthesize vitamin c (vc) because they lacked activity of l-gulonolactone oxidase (gulo) in their livers. humans and guinea pigs lack the activity due to pseudogenization of gulo in their genomes, but there is no genetic evidence to show whether such loss in bats is caused by pseudogenization. unexpectedly, our successful molecular cloning in one frugivorous bat (rousettus leschenaultii) and one insectivor ... | 2010 | 21037206 |

We found that telomerase activity was present in all tissues sampled, but it was greater in metabolically active tissues such as liver, spleen, and kidney. Of special interest is the raised activity found in the heterothermic bat H. armiger, and the hibernating bats having raised values for spleen, heart, and kidney. ... | 2011 | 22082270 |

| characterization of microsatellite loci in fulvous fruit bat rousettus leschenaulti. | rousettus leschenaulti is an abundant species in many countries of south-east asia, including south china. we isolated seven microsatellite loci in r. leschenaulti from genomic dna enriched for ca repeats with the enriched library method. a total of 56 samples from a population in the guangxi province of china were tested with these microsatellite markers. the polymorphism ranged from seven to 16 alleles, and the observed heterozygosity was 84-94%. it is the first time microsatellite markers wer ... | 2006 | 32355465 |
| comparative genomic analyses illuminate the distinct evolution of megabats within chiroptera. | the revision of the sub-order microchiroptera is one of the most intriguing outcomes in recent mammalian molecular phylogeny. the unexpected sister-taxon relationship between rhinolophoid microbats and megabats, with the exclusion of other microbats, suggests that megabats arose in a relatively short period of time from a microbat-like ancestor. in order to understand the genetic mechanism underlying adaptive evolution in megabats, we determined the whole-genome sequences of two rousette megabat ... | 2020 | 32966557 |
| 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 |
| extracellular matrix composition of different spleen compartments of fruit bats. | the distribution and composition of extracellular matrix (ecm) of the spleen in two species of fruit bats, namely cynopterus titthaecheilus and rousettus leschenaultii, were examined by histochemistry and immunohistochemistry. reticular fibres accompanied by laminin were identified to make up the splenic stromal network. types i and iii collagen were identified in various spleen compartments with varying intensities. thin and short elastin fibres were scattered in several parts of the spleen. vi ... | 2020 | 31877588 |
| filovirus-reactive antibodies in humans and bats in northeast india imply zoonotic spillover. | bats are reservoirs for several zoonotic pathogens, including filoviruses. recent work highlights the diversity of bat borne filoviruses in asia. high risk activities at the bat-human interface pose the threat of zoonotic virus transmission. we present evidence for prior exposure of bat harvesters and two resident fruit bat species to filovirus surface glycoproteins by screening sera in a multiplexed serological assay. antibodies reactive to two antigenically distinct filoviruses were detected i ... | 2019 | 31671094 |
