| 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 |
| 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 |
| 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 |
| 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 |
| 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 |
| 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 |
| 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 |
