| geographic variations, cloning, and functional analyses of the venom acidic phospholipases a2 of crotalus viridis viridis. | geographic venom samples of crotalus viridis viridis were obtained from south dakota, wyoming, colorado, oklahoma, texas, new mexico, and arizona. from these samples, the phospholipases a(2) (pla(2)s) were purified and their n-terminal sequences, precise masses, and in vitro enzymatic activities were determined. we purified two to four distinct acidic pla(2)s from each sample; some of them displayed different inhibition specificities toward mammalian platelets. one of the acidic pla(2)s induced ... | 2003 | 12623078 |
| venom characteristics as an indicator of hybridization between crotalus viridis viridis and crotalus scutulatus scutulatus in new mexico. | one hundred and thirteen venoms from 46 populations of crotalus viridis viridis were screened by immunodiffusion for protein toxins antigenically similar to the phospholipase a2 (pla) toxin 'mojave toxin', using a polyclonal antibody to it's basic pla subunit. venom i.p. ld50 values in mice were recorded from 22 of the 46 populations. the venoms of three of 14 specimens from southwest (s.w.) new mexico and one specimen from northern arizona were immunologically positive by the immunodiffusion te ... | 1990 | 2120798 |
| eimeria crotalviridis sp. n. from prairie rattlesnakes, crotalus viridis viridis, in new mexico with data on excystation of sporozoites and ultrastructure of the oocyst wall. | oocysts of eimeria crotalviridis sp. n. are described from praire rattlesnakes, crotalus viridis viridis in new mexico on the basis of light and electron microscopy and in vitro excystation of sporozoites. sporulated oocysts of e. crotalviridis are elliptical, 26.4 x 22.3 (23-29 x 20-24) micrometer with ovoid sporocysts 11.7 x 8.1 (11-13 x 7-9) micromiter. a micropyle, micropyle cap and polar bodies are absent, but oocyst and sporocyst residua and stieda and substieda bodies are present. excyste ... | 1977 | 915840 |
| 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 |
