| drinking and flying: does alcohol consumption affect the flight and echolocation performance of phyllostomid bats? | in the wild, frugivorous and nectarivorous bats often eat fermenting fruits and nectar, and thus may consume levels of ethanol that could induce inebriation. to understand if consumption of ethanol by bats alters their access to food and general survival requires examination of behavioural responses to its ingestion, as well as assessment of interspecific variation in those responses. we predicted that bats fed ethanol would show impaired flight and echolocation behaviour compared to bats fed co ... | 2010 | 20126552 |
| identification of cortical germ cells in adult ovaries from three phyllostomid bats: artibeus jamaicensis, glossophaga soricina and sturnira lilium. | it is generally considered that, in mammals, the ovary is endowed with a finite number of oocytes at the time of birth. however, studies concerning rodents, lemurs and humans suggest the existence of stem cells from the germline that may be involved in germ-cell renewal, maintaining postnatal follicle development. this type of work on wild species is scarce; therefore the objective of this study was to determine ovarian morphology and the presence of progenitor cells from the germline of three s ... | 2013 | 22953782 |

| gonadal morphogenesis and establishment of the germline in the phyllostomid bat sturnira lilium. | in vertebrates such as the mouse and the human, primordial germ cells (pgcs) arise at the base of the allantois and are carried to the epithelium of the posterior intestine, to later migrate to the primordial gonads. in the case of bats, almost nothing is known about this process. to clarify the dynamics of pgcs during gonadal morphogenesis in the phyllostomid bat sturnira lilium, the proteins for the ddx4, sox9 and mis genes were detected in the gonads of embryos at different stages of developm ... | 2017 | 28823522 |
| reproductive biology of the bat sturnira lilium (chiroptera, phyllostomidae) in the atlantic forest of rio de janeiro, southeastern brazil. | bats can be monoestrous or polyestrous, and seasonal or non-seasonal in their reproductive patterns. the strategy adopted by each species or population depends on the regional climate. the objective this study was to analyze reproductive data of sturnira lilium from long-term sampling carried out in several sites in rio de janeiro states, southeastern brazil. we carried out sampling in 42 sites (with altitudes ranging from sea level to 1300 m a.s.l.) from may 1989 to december 2011. in total, we ... | 2014 | 25627603 |
| evaluation of the cell population of the seminiferous epithelium and spermatic indexes of the bat sturnira lilium (chiroptera: phyllostomidae). | due to the scarcity of information about patterns of spermatogenesis in bats, this study aimed to provide information on the testicular activity of the bat sturnira lilium along the annual seasons. thus, a series of morphometrical and stereological analyses were made using the testes of adult s. lilium in order to achieve a better understanding of the sperm production dynamics. light and transmission electron microscopy analyses were performed in testicular fragments of animals captured during d ... | 2014 | 25003782 |
| a comparative immunohistochemical study of endocrine cells in the digestive tract of two frugivorous bats: artibeus cinerius and sturnira lilium. | the purpose of the present study was to examine the serotonin (5-hydroxytryptamine, 5-ht), gastrin (gas), cholecystokinin (cck) and glucagon (gluc) endocrine cells in the gastrointestinal tract of frugivorous phillostomidae bats, sturnira lilium and artibeus cinerius, to clarify the correlation between distribution of cell types and their relative frequency, with feeding habits. five portions of the gastrointestinal tract--fundus, pilorus, and three parts of the intestine, i, ii and iii--were ex ... | 2008 | 18068220 |
| crystal structures of two subtype n10 neuraminidase-like proteins from bat influenza a viruses reveal a diverged putative active site. | recently, we reported a unique influenza a virus subtype h17n10 from little yellow-shouldered bats. its neuraminidase (na) gene encodes a protein that appears to be highly divergent from all known influenza nas and was assigned as a new subtype n10. to provide structural and functional insights on the bat h17n10 virus, x-ray structures were determined for n10 na proteins from influenza a viruses a/little yellow-shouldered bat/guatemala/164/2009 (gu09-164) in two crystal forms at 1.95 å and 2.5 å ... | 2012 | 23012478 |
| specific mutations in the pb2 protein of influenza a virus compensate for the lack of efficient interferon antagonism of the ns1 protein of bat influenza a-like viruses. | recently, two new influenza a-like viruses have been discovered in bats, a/little yellow-shouldered bat/guatemala/060/2010 (hl17nl10) and a/flat-faced bat/peru/033/2010 (hl18nl11). the hemagglutinin (ha)-like (hl) and neuraminidase (na)-like (nl) proteins of these viruses lack hemagglutination and neuraminidase activities, despite their sequence and structural homologies with the ha and na proteins of conventional influenza a viruses. we have now investigated whether the ns1 proteins of the hl17 ... | 2018 | 29321309 |
| structural and functional characterization of neuraminidase-like molecule n10 derived from bat influenza a virus. | the recent discovery of the unique genome of influenza virus h17n10 in bats raises considerable doubt about the origin and evolution of influenza a viruses. it also identifies a neuraminidase (na)-like protein, n10, that is highly divergent from the nine other well-established serotypes of influenza a na (n1-n9). the structural elucidation and functional characterization of influenza nas have illustrated the complexity of na structures, thus raising a key question as to whether n10 has a special ... | 2012 | 23012237 |
| landscape ecology of trypanosoma cruzi in the southern yucatan peninsula. | landscape interactions of trypanosoma cruzi (tc) with triatoma dimidiata (td) depend on the presence and relative abundance of mammal hosts. this study analyzed a landscape adjacent to the calakmul biosphere reserve, composed of conserved areas, crop and farming areas, and the human community of zoh laguna with reported chagas disease cases. sylvatic mammals of the chiroptera, rodentia, and marsupialia orders were captured, and livestock and pets were sampled along with t. dimidiata in all habit ... | 2015 | 26219998 |
| serological evidence of arenavirus circulation among fruit bats in trinidad. | tacaribe virus (tcrv) was isolated in the 1950s from artibeus bats captured on the island of trinidad. the initial characterization of tcrv suggested that artibeus bats were natural reservoir hosts. however, nearly 60 years later experimental infections of jamaican fruit bats (artibeus jamaicensis) resulted in fatal disease or clearance, suggesting artibeus bats may not be a reservoir host. to further evaluate the tcrv reservoir host status of artibeus bats, we captured bats of six species in tr ... | 2017 | 28953976 |
