| dengue virus in mexican bats. | individuals belonging to five families, 12 genera, and 19 different species of bats from dengue endemic areas in the gulf and pacific coasts of mexico were examined by elisa, rt-pcr, and for the presence of dengue virus (dv) ns1 protein. nine individuals from four species were seropositive by elisa: three insectivorous, myotis nigricans (four positives/12 examined), pteronotus parnellii (3/19), and natalus stramineus (1/4), and one frugivorous artibeus jamaicensis (1/35) (12.86% seroprevalence i ... | 2008 | 18325131 |
| serologic evidence of flavivirus infection in bats in the yucatan peninsula of mexico. | we captured 140 bats of seven species in merida city in the yucatan peninsula of mexico in 2010. serum was collected from each bat and assayed by plaque reduction neutralization test (prnt) using six flaviviruses: west nile virus, st. louis encephalitis virus, and dengue viruses 1-4. flavivirus-specific antibodies were detected in 26 bats (19%). the antibody-positive bats belonged to three species: the pallas's long-tongued bat (glossophaga soricina), jamaican fruit bat (artibeus jamaicensis), a ... | 0 | 23778622 |
| experimental inoculation of artibeus jamaicensis bats with dengue virus serotypes 1 or 4 showed no evidence of sustained replication. | dengue is the most important mosquito-borne viral disease to humans. bats are potential reservoirs for flaviviruses, including dengue virus (denv). in this work, artibeus jamaicensis bats were inoculated with two serotypes of denv using different routes. for experimental inoculations (ei) 1 and 2, bats were inoculated subcutaneously or intraperitoneally with denv-4; for ei-3 bats were inoculated intraperitoneally with denv-1. mock inoculated bats were kept as controls. in ei-4, bats were bitten ... | 2014 | 25311698 |
| dengue virus in bats from southeastern mexico. | to identify the relationship between landscape use and dengue virus (denv) occurrence in bats, we investigated the presence of denv from anthropogenically changed and unaltered landscapes in two biosphere reserves: calakmul (campeche) and montes azules (chiapas) in southern mexico. spleen samples of 146 bats, belonging to 16 species, were tested for four denv serotypes with standard reverse transcriptase polymerase chain reaction (rt-pcr) protocols. six bats (4.1%) tested positive for denv-2: fo ... | 2014 | 24752688 |
| neotropical primary bat cell lines show restricted dengue virus replication. | dengue is the most widespread arboviral disease affecting humans. bats are recognized carriers of emerging viral zoonoses and have been proposed as dengue reservoirs, since rna/ns1 and/or antiviral antibodies have been detected. yet, experimental inoculation of artibeus bats failed to show virus replication. this conflicting results prevent drawing further conclusions of whether bats sustain dengue infection. to test bat cellular permissivity to dengue infection, we established primary bat embry ... | 2017 | 28131369 |
| host and viral traits predict zoonotic spillover from mammals. | the majority of human emerging infectious diseases are zoonotic, with viruses that originate in wild mammals of particular concern (for example, hiv, ebola and sars). understanding patterns of viral diversity in wildlife and determinants of successful cross-species transmission, or spillover, are therefore key goals for pandemic surveillance programs. however, few analytical tools exist to identify which host species are likely to harbour the next human virus, or which viruses can cross species ... | 2017 | 28636590 |
| serological evidence of widespread exposure of grenada fruit bats to chikungunya virus. | antibody detection against selected potentially zoonotic vector-borne alphaviruses and flaviviruses was conducted on sera from bats from all six parishes in grenada, west indies. sera were tested for (i) antibodies to flaviviruses west nile virus, st. louis encephalitis virus, ilhéus virus, bussuquara virus (bsqv), rio bravo virus and all four serotypes of dengue virus (denv) by plaque reduction neutralization test (prnt); (ii) antibodies to alphaviruses western equine encephalitis virus, venezu ... | 2018 | 29575672 |
| hematologic values of jamaican fruit bats (artibeus jamaicensis) and the effects of isoflurane anesthesia. | jamaican fruit bats (artibeus jamaicensis) are used as an animal model for several viruses, including middle east respiratory syndrome virus, dengue virus, zika virus, and tacaribe virus. however, despite ongoing studies regarding these pathogens, little is known regarding the bats' normal physiology. in this study, phlebotomy of the propetagial (cephalic) vein was performed to establish baseline hematologic parameters in an apparently healthy, captive population of jamaican fruit bats. furtherm ... | 2020 | 32164795 |
| current knowledge and ecological and human impact variables involved in the distribution of the dengue virus by bats in the americas. | dengue fever, caused by the dengue virus (denv), is one of the most important reemerging viral diseases transmitted by arthropods worldwide. denv is maintained in nature in two transmission cycles: urban and sylvatic. the latter has only been recorded in africa and asia and involves nonhuman primates as natural hosts, although it has been suggested that other mammals may play a secondary role as potential reservoir host, including bats. the objective of this article is to review the current stat ... | 2021 | 33439764 |
