| characterization of venom (duvernoy's secretion) from twelve species of colubrid snakes and partial sequence of four venom proteins. | r.e. hill and s.p. mackessy. characterization of venom (duvernoy's secretion) from twelve species of colubrid snakes and partial sequence of four venom proteins. toxicon xx, xx-yy, 2000. - venomous colubrids, which include more than 700 snake species worldwide, represent a vast potential source of novel biological compounds. the present study characterized venom (duvernoy's gland secretion) collected from twelve species of opisthoglyphous (rear-fanged) colubrid snakes, an extremely diverse assem ... | 2000 | 10858509 |
| morphologic and morphometric analysis of hepatozoon spp. (apicomplexa, hepatozoidae) of snakes. | hepatozoon species are the most abundant hemoparasites of snakes. its identification has been based mainly on the morphologic characterization of the gamonts in the peripheral blood of the vertebrate host and also of the cysts found in the internal organs of the vertebrate and invertebrate hosts. using a computerized image analysis system, we studied five species of hepatozoon from recently captured snakes in botucatu, state of s o paulo, brazil, to evaluate the importance of the morphology and ... | 2003 | 12563486 |
| seasonal variation of hepatozoon spp. (apicomplexa, hepatozoidae) parasitemia from boa constrictor amarali (serpentes, boidae) and hydrodynastes gigas (serpentes, colubridae). | the aim of this study was to evaluate the parasitemia variation of three hepatozoon species in brazilian snakes. this study was conducted between 2001 and 2003 and included hepatozoon terzii from boa constrictor amarali, and hepatozoon migonei and hepatozoon cyclagrasi from hydrodynastes gigas. it was observed that the parasitemia tended to decrease in all three hepatozoon species but the parasites were not eliminated. this data suggest that hepatozoon infection may be similar to toxoplasma gond ... | 2005 | 15999279 |
| new tick records from the state of rondônia, western amazon, brazil. | from 2005 to 2012, ticks were collected from different hosts at different localities of the state of rondônia. the following 16 ixodid tick species were identified: ixodes fuscipes, amblyomma auricularium, amblyomma coelebs, amblyomma dubitatum, amblyomma geayi, amblyomma humerale, amblyomma latepunctatum, amblyomma longirostre, amblyomma naponense, amblyomma nodosum, amblyomma oblongoguttatum, amblyomma ovale, amblyomma romitii, amblyomma rotundatum, amblyomma scalpturatum, and amblyomma varium ... | 2014 | 23975565 |
| [cammalanus railliet and henry, 1915 (nematoda, camallanidae). parasite from hydrodynastes gigas (reptilia, serpentes, colubridae) from argentine chaco]. | adult specimens of camallanus genus (nematoda, camallanidae), parasitizing a hydrodynastes gigas (serpentes, colubridae) from chaco in the north east of argentina, are described for the first time. the morphologic and morphometric parasitological studies were carried out using diaphanization by lactophenol technique. the specimens described were drawn and photographed. with this investigation the analysis of the reptilian pathologies, the knowledge of which is necessary to make projects, to mana ... | 2006 | 9302777 |
| local envenomation from the bite of a juvenile false water cobra (hydrodynastes gigas; dipsadidae). | the false water cobra (hydrodynastes gigas) is a non-front-fanged colubroid snake frequently exhibited in zoos, and maintained by amateur collectors. little detailed documentation regarding the time-course of symptoms development and the consequences of their bites to humans has been published. reported here is a case of envenoming in a 25 yo male that occurred after the bite of a juvenile h. gigas. the victim was bitten on the fourth digit of the left hand while processing the snake for sex det ... | 2016 | 26743113 |

| utilization of natural history information in evidence based herpetoculture: a proposed protocol and case study with hydrodynastes gigas (false water cobra). | herpetocultural practices are based on norms driven by economy of space and time for keepers, with little scientific inference backing their practice. in recent years, a subset of herpetoculturalists have promoted evidence-based husbandry that relies on science and experimental design to generate husbandry practice. a theoretical framework and protocol are proposed herein that enables any individual who has access to the internet the ability to use various outlets of natural history information ... | 2020 | 33153054 |
