| a report of intestinal sarcocystosis in the bullsnake (pituophis melanoleucus sayi) and a re-evaluation of sarcocystis sp. from snakes of the genus pituophis. | we report a severe enteric infection of sarcocystis sp. from a wild-caught bullsnake (pituophis melanoleucus sayi). the animal was collected in october 1988 by a commercial dealer, imported into the united kingdom during november 1988 and purchased by the london zoo, in december 1988. the animal was not fed after capture and was anorexic from the time of purchase to the time of death in january 1989. on necropsy, the animal was emaciated and the mucosa of the proximal intestine was markedly thic ... | 1995 | 8592365 |
| parasites of prairie rattlesnakes (crotalus viridis viridis) and gopher snakes (pituophis melanoleucus sayi) from the eastern high plains of new mexico. | three prairie rattlesnakes (crotalus viridis viridis) and two gopher snakes (pituophis melanoleucus sayi) from the eastern high plains of new mexico (usa) were examined for parasites. one cestode (oochoristica osheroffi), and two nematode (kalicephalus inermis and physoloptera retusa) species were recovered from two infected rattlesnakes. one female gopher snake was infected with two nematode (k. inermis and rhabdias spp.) and one mite (entonyssus halli) species. | 1989 | 2716118 |
| conservation genetics of the eastern yellow-bellied racer (coluber constrictor flaviventris) and bullsnake (pituophis catenifer sayi): river valleys are critical features for snakes at northern range limits. | on the north american great plains, several snake species reach their northern range limit where they rely on sparsely distributed hibernacula located in major river valleys. independent colonization histories for the river valleys and barriers to gene flow caused by the lack of suitable habitat between them may have produced genetically differentiated snake populations. to test this hypothesis, we used 10 microsatellite loci to examine the population structure of two species of conservation con ... | 2017 | 29095863 |
| [cryptosporidiosis in adders (pituiophis melanoleucus sayi)]. | infection of snakes with cryptosporidia is known to occur as hypertrophic gastritis associated with postprandial regurgitation. this is a report of a severe and fatal intestinal cryptosporidiosis in a group of snakes (pituophis melanoleucus sayi) kept at a zoological garden. the clinical and pathological findings are described and discussed in this paper. pathohistologically fibrinous, diphtheroid and necrotizing enteritides were diagnosed. histological examination was completed by electron micr ... | 1998 | 9531675 |
| characterization of bradykinin-related peptides generated in the plasma of six sarcopterygian species (african lungfish, amphiuma, coachwhip, bullsnake, gila monster, and gray's monitor). | incubation of heat-denatured plasma from six species occupying different evolutionary positions within the sarcopterygian lineage [the dipnoan, protopterus annectens (african lungfish); the urodele, amphiuma tridactylum (three-toed amphiuma); the colubrid snakes, pituophis melanoleucus sayi (bullsnake) and masticophis flagellum (coachwhip); and the lizards heloderma suspectum (gila monster) and varanus grayi (gray's monitor)] with trypsin generated bradykinin-related peptides that were detected ... | 1998 | 9748409 |
