| 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 |
| 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 |
