| virtopsy of a gravid boa constrictor using computed tomography and magnetic resonance imaging. | this article presents radiologic examinations of a deeply sedated boa constrictor with boid inclusion body disease (bibd) as an adjunction to the subsequent necropsy. this method is known as virtopsy. the boa constrictor in the present case was gravid. computed tomography (ct) allowed for the detailed depiction of a fetal skeleton at the rear end of the adult snake. furthermore, tiny gas formation was detected inside the cranium of the fetus, which was deemed a radiologic sign for decomposition. ... | 2020 | 33089008 |
| cooperative rescue of a juvenile capuchin (cebus imitator) from a boa constrictor. | the threat of predation by snakes is considered to have played a significant role in the evolution of primate sensory systems and behavior. however, we know relatively little about individual and group responses given the rarity of observed predation events. here we report an observed (filmed) predation attempt by an adult boa constrictor (~ 2 m) on a juvenile white-faced capuchin (cebus imitator) in the sector santa rosa of the área de conservación guanacaste, costa rica. the snake caught the j ... | 2020 | 33033278 |
| protein electrophoresis of plasma samples from boa constrictors with and without reptarenavirus infection. | reptarenaviruses infect a variety of boid and pythonid snake species worldwide and have been shown to be the cause of inclusion body disease (ibd). little is known about the correlations between virus infection and clinical disease, as well as the effects of viral infection on the immune system and the blood protein fractions. the goal of this study was to examine the differences in the plasma protein fractions in reptarenavirus reverse transcription polymerase chain reaction (rt-pcr)-negative a ... | 2020 | 32549564 |
| flesh flies (diptera: sarcophagidae) attracted to a snake carcass (boa constrictor) in yucatan peninsula, mexico. | a study was carried out to determine sarcophagidae diversity attracted to the different stages of decomposition of a boa constrictor cadaver during late winter in the yucatan peninsula. as a result of this study, seven species of sarcophagidae were documented, oxysarcodexia conclausa (walker, 1861) (diptera: sarcophagidae), peckia (euboettcheria) volucris (wulp, 1895) (diptera: sarcophagidae), blaesoxipha (gigantotheca) plinthopyga (wiedemann, 1830) (diptera: sarcophagidae), oxysarcodexia amoros ... | 2020 | 32533178 |
| leptospira interrogans in wild boa constrictor snakes from northeast brazil peri‑urban rainforest fragments. | leptospirosis, a disease that occurs worldwide, especially in tropical regions, is caused by bacteria of the genus leptospira and affects mammals, amphibians, and reptiles. boa constrictor snakes are commonly found in atlantic rainforest fragments in peri‑urban areas, which indicates a greater possibility of the contact of these animals with humans residing there. therefore, the aim of this work was to detect leptospira spp infection through molecular assays in wild b. constrictor snakes rescued ... | 2020 | 32504590 |
| identification of reptarenaviruses, hartmaniviruses, and a novel chuvirus in captive native brazilian boa constrictors with boid inclusion body disease. | boid inclusion body disease (bibd) is a transmissible viral disease of captive snakes that causes severe losses in snake collections worldwide. it is caused by reptarenavirus infection, which can persist over several years without overt signs but is generally associated with the eventual death of the affected snakes. thus far, reports have confirmed the existence of reptarenaviruses in captive snakes in north america, europe, asia, and australia, but there is no evidence that it also occurs in w ... | 2020 | 32238580 |
| identification and characterization of the first endogenous phospholipase a2 inhibitor from a non-venomous tropical snake, boa constrictor (serpentes: boidae). | endogenous phospholipase a2 inhibitors from snake blood (sbplis) have been isolated from several species around the world, with the primary function of self-protection against the action of toxic phospholipases a2. in american snakes, sbplis were solely described in pit vipers, in which the natural protection role is justified. in this study, we described a sbpli in boa constrictor (popularly known as jiboia), a non-venomous snake species from america. | 2020 | 32231698 |
| detection of an arenavirus in a group of captive wagler's pit vipers (tropidolaemus wagleri). | a group of eight wagler's pit vipers (tropidolaemus wagleri) from a private collection died with respiratory signs within 6 mo of one another. the group consisted of an adult breeding pair that was wild caught and six offspring from this pair. four of the dead snakes were submitted for gross and histopathology. signs of bacterial pneumonia were detected in all four examined snakes. no inclusion bodies suggestive of viral infection were found in any of the examined tissues. polymerase chain react ... | 2020 | 32212570 |
| experimental modification of morphology reveals the effects of the zygosphene-zygantrum joint on the range of motion of snake vertebrae. | variation in joint shape and soft tissue can alter range of motion (rom) and create trade-offs between stability and flexibility. the shape of the distinctive zygosphene-zygantrum joint of snake vertebrae has been hypothesized to prevent axial torsion (twisting), but its function has never been tested experimentally. we used experimental manipulation of morphology to determine the role of the zygosphene-zygantrum articulation by micro-computed tomography (μct) scanning and 3d printing two mid-bo ... | 2020 | 32127376 |
| molecular detection of reptile-associated borrelia in boa constrictor (squamata: boidae) from veracruz, mexico. | the reptile-associated borrelia represent a monophyletic group of bacteria transmitted by several species of hard ticks, which has been reported to only infect amphibians and reptiles in eurasia and middle east, however, this bacterial group has not been studied in north america. the aim of this study was to assess the presence of borrelia spirochetes in blood samples of native reptiles of mexico. blood samples were directly obtained from individuals, dna extractions were performed using chelex- ... | 2020 | 32112720 |
| active anti-predator behaviour of red titi monkeys (plecturocebus cupreus). | due to their inconspicuous behaviour and colouration, it has been assumed that titi monkeys' main anti-predator behaviour is passive crypsis and hiding. so far, active predator mobbing has been documented only for black-fronted titi monkeys, callicebusnigrifrons. here we report for the first time mobbing behaviour of red titi monkeys, plecturocebus cupreus (previously callicebus cupreus), as reaction to an ocelot (leopardus pardalis) and a boa constrictor. we also report other active anti-predat ... | 2019 | 32110716 |
| boaγpli: structural and functional characterization of the gamma phospholipase a2 plasma inhibitor from the non-venomous brazilian snake boa constrictor. | plasma in several organisms has components that promote resistance to envenomation by inhibiting specific proteins from snake venoms, such as phospholipases a2 (pla2s). the major hypothesis for inhibitor's presence would be the protection against self-envenomation in venomous snakes, but the occurrence of inhibitors in non-venomous snakes and other animals has opened new perspectives for this molecule. thus, this study showed for the first time the structural and functional characterization of t ... | 2020 | 32106235 |
| visual contrast and intensity affect perch choice of brown tree snakes (boiga irregularis) and boa constrictors (boa constrictor). | habitat structure can affect animal movement both by affecting the mechanical demands of locomotion and by influencing where animals choose to go. arboreal habitats facilitate studying path choice by animals because variation in branch structure has known mechanical consequences, and different branches create discrete choices. recent laboratory studies have found that arboreal snakes can use vision to select shapes and locations of destinations that mechanically facilitate bridging gaps. however ... | 2020 | 32070798 |
| effects of brodifacoum and diphacinone exposure on four species of reptiles: tissue residue levels and survivorship. | anticoagulant rodenticides are used worldwide to control pest rodent species. however, the risks posed to non-target reptiles have not been well characterized. in this study, 46 giant ameivas (ameiva ameiva), 39 boa constrictors (boa constrictor), 33 wood turtles (rhinoclemmys pulcherrima), and 47 green iguanas (iguana iguana) were orally dosed with one of two levels of either diphacinone or brodifacoum anticoagulant in propylene glycol solutions. dosages were derived using daily food intake (df ... | 2020 | 31858711 |
| genomic basis of convergent island phenotypes in boa constrictors. | convergent evolution is often documented in organisms inhabiting isolated environments with distinct ecological conditions and similar selective regimes. several central america islands harbor dwarf boa populations that are characterized by distinct differences in growth, mass, and craniofacial morphology, which are linked to the shared arboreal and feast-famine ecology of these island populations. using high-density radseq data, we inferred three dwarf island populations with independent origin ... | 2019 | 31642474 |
| antibody response in snakes with boid inclusion body disease. | boid inclusion body disease (bibd) is a potentially fatal disease reported in captive boid snakes worldwide that is caused by reptarenavirus infection. although the detection of intracytoplasmic inclusion bodies (ib) in blood cells serves as the gold standard for the ante mortem diagnosis of bibd, the mechanisms underlying ib formation and the pathogenesis of bibd are unknown. knowledge on the reptile immune system is sparse compared to the mammalian counterpart, and in particular the response t ... | 2019 | 31498825 |
| human, nonhuman primate, and bat cells are broadly susceptible to tibrovirus particle cell entry. | in 2012, the genome of a novel rhabdovirus, bas-congo virus (basv), was discovered in the acute-phase serum of a congolese patient with presumed viral hemorrhagic fever. in the absence of a replicating virus isolate, fulfilling koch's postulates to determine whether basv is indeed a human virus and/or pathogen has been impossible. however, experiments with vesiculoviral particles pseudotyped with bas-congo glycoprotein suggested that basv particles can enter cells from multiple animals, includin ... | 2019 | 31105663 |
| identification of a novel deltavirus in boa constrictors. | hepatitis d virus (hdv) forms the genus deltavirus unassigned to any virus family. hdv is a satellite virus and needs hepatitis b virus (hbv) to make infectious particles. deltaviruses are thought to have evolved in humans, since for a long time, they had not been identified elsewhere. herein we report, prompted by the recent discovery of an hdv-like agent in birds, the identification of a deltavirus in snakes (boa constrictor) designated snake hdv (shdv). the circular 1,711-nt rna genome of shd ... | 2019 | 30940697 |
