    Zookeys 2019; 875:1-29Janssen HY, Pham CT, … Ziegler T
  • A new species of the genus Lycodon is described from Cao Bang Province, Vietnam, based on three individuals with distinct differences in morphology and molecular data. The new species is differentiated from its congeners by a combination of the following characters: dorsal scales in 17-17-15 rows, smooth throughout; supralabials usually eight (rarely nine); infralabials ten; one elongated loreal …
  • StatPearls: Water Moccasin Snake Toxicity [BOOK]
    StatPearls Publishing: Treasure Island (FL) Thackston Derek D VCU Health Wills Brandon K. BK Virginia Commonwealth University BOOK
  • The water moccasin or cottonmouth, Agkistrodon piscivorus, is a semi-aquatic pit viper found throughout the Southeastern United States and into West Texas[1] Their two common names derive from the white-colored membranes in its mouth and living near sources of water. Cottonmouth snakes are part of the Crotalinae family of pit vipers which includes rattlesnakes and copperheads.  Like the other Nor…
  • Characterization of the melanopsin gene (Opn4x) of diurnal and nocturnal snakes. [Journal Article]
    BMC Evol Biol 2019; 19(1):174Hauzman E, Kalava V, … Ventura DF
  • CONCLUSIONS: The loss of the Opn4m gene and extra-ocular photosensitive tissues in snakes may be associated with a prolonged nocturnal/mesopic bottleneck in the early history of snake evolution. The presence of melanopsin-containing cells in all retinal nuclear layers indicates a globally photosensitive retina, and the expression in classic photoreceptor cells suggest a regionalized co-expression of melanopsin and visual opsins.
  • Non-venomous snakebites in the Western Brazilian Amazon. [Journal Article]
    Rev Soc Bras Med Trop 2019; 52:e20190120Silva AMD, Mendes VKDG, … Bernarde PS
  • CONCLUSIONS: The symptoms produced by the snakes Helicops angulatus and Philodryas viridissima, combined with their coloration can be confused with venomous snakes (Bothrops atrox and Bothrops bilineatus), thus resulting in incorrect bothropic snakebite diagnosis.
  • Envenomation by an opisthoglyphous snake, Erythrolamprus aesculapii (Dipsadidae), in southeastern Brazil. [Case Reports]
    Rev Soc Bras Med Trop 2019; 52:e20190055Menegucci RC, Bernarde PS, … Martins M
  • Snakebites by aglyphous or opisthoglyphous snakes are common in Brazil. We report a case of snakebite by the opisthoglyphous Erythrolamprus aesculapii. The victim presented with pain, edema, and bleeding at the bite site, along with erythema, similar to a Bothrops envenomation. In this type of snakebite, if the snake is not brought to the hospital, the victim may receive unnecessary serum therapy…
  • Persistent pit viper envenomation in three dogs. [Journal Article]
    Toxicon 2019; 166:83-87Schaer M
  • CONCLUSIONS: The clinical course of the three dogs described in this study showed that veterinary patients can experience persistent envenomation in a similar manner as described in humans. It behooves the veterinary practitioner to be aware of this complication and to be prepared to extend antivenom treatment as deemed necessary.
