| seasonality and synchrony of reproduction in three species of nectarivorous philippines bats. | differences among species and among years in reproductive seasonality (the tendency for clusters of events to fall at approximately the same point in each year) and synchrony (amount of clustering of events within a year) have been intensively studied in bats, but are difficult to assess. here, we use randomization methods with circular statistics to test for synchrony and seasonality of reproduction in three species of nectarivorous megachiropteran bats on negros island in the central philippin ... | 2003 | 14633285 |
| detection of campylobacter jejuni in rectal swab samples from rousettus amplexicaudatus in the philippines. | bats are the second diversity species of mammals and widely distributed in the world. they are thought to be reservoir and vectors of zoonotic pathogens. however, there is scarce report of the evidence of pathogenic bacteria kept in bats. the precise knowledge of the pathogenic bacteria in bat microbiota is important for zoonosis control. thus, metagenomic analysis targeting the v3-v4 region of the 16s rrna of the rectal microbiota in rousettus amplexicaudatus was performed using high throughput ... | 2016 | 27109214 |
| the distribution of henipaviruses in southeast asia and australasia: is wallace's line a barrier to nipah virus? | nipah virus (niv) (genus henipavirus) is a recently emerged zoonotic virus that causes severe disease in humans and has been found in bats of the genus pteropus. whilst niv has not been detected in australia, evidence for niv-infection has been found in pteropid bats in some of australia's closest neighbours. the aim of this study was to determine the occurrence of henipaviruses in fruit bat (family pteropodidae) populations to the north of australia. in particular we tested the hypothesis that ... | 2013 | 23637812 |
| detection and molecular characterization of cryptosporidium and eimeria species in philippine bats. | the genus cryptosporidium, which is an obligate intracellular parasite, infects various vertebrates and causes a diarrheal disease known as cryptosporidiosis. bats are naturally infected with zoonotic pathogens; thus, they are potential reservoirs of parasites. we investigated the species and genotype distribution as well as prevalence of cryptosporidium and eimeria in philippine bats. we captured and examined 45 bats; four were positive for cryptosporidium spp. and seven were positive for eimer ... | 2016 | 26833326 |
| heterochrony in limb evolution: developmental mechanisms and natural selection. | the tetrapod limb provides several examples of heterochrony-changes in the timing of developmental events. these include species differences in the sequence of skeletal chondrogenesis, in gene transcription in the developing limbs, and in the relative time at which forelimb and hind limb buds develop. here, we examine (i) phylogenetic trends in limb heterochrony; (ii) changes in developmental mechanisms that may lead to heterochrony; and (iii) the possible role that heterochrony plays in generat ... | 2009 | 19130597 |
| molecular phylogeny of a genetically divergent hantavirus harbored by the geoffroy's rousette (rousettus amplexicaudatus), a frugivorous bat species in the philippines. | the recent discovery of genetically distinct hantaviruses in multiple species of shrews and moles (order eulipotyphla, families soricidae and talpidae) prompted a further exploration of their host diversification and geographic distribution by analyzing lung tissues from 376 fruit bats representing six genera (order chiroptera, suborder yinpterochiroptera, family pteropodidae), collected in the republic of the philippines during 2008 to 2013. hantavirus rna was detected by rt-pcr in one of 15 ge ... | 2016 | 27516187 |
| the distribution of serotonergic nerve on the hippocampus of the fruit bats (rousettus amplexicaudatus). | rousettus amplexicaudatus is one of the old world fruit bats, commonly known in javanese word as codot belongs to order chiroptera and suborder megachiroptera. r. amplexicaudatus possessed an outstanding visual ability, which helps in the process of searching for food. those activities process and save within the brain involving the learning and memory activities. learning and memory activities are centered around the hippocampus with the help of serotonergic nerve. | 2019 | 31749582 |
| morphological study of the lingual papillae in the fruit bat (rousettus amplexicaudatus) by scanning electron microscopy and light microscopy. | this study was carried on the tongues of ten normal, healthy and adult fruit bats (rousettus amplexicaudatus, also known as the nyap biasa bat) in yogyakarta, java island, indonesia. the tongue was protrusible, elongated and flat with a rounded apex, and its width and thickness increased gradually towards to lingual root. there were two main types of lingual papillae, mechanical (filiform) and gustatory (fungiform and circumvallate). the tongue was divided into three parts (apex, corpus and radi ... | 2020 | 31696546 |
