| assessment of the antimicrobial activity of few saudi arabian snake venoms. | venoms of two cobras, four vipers, a standard antibiotic and an antimycotic, were evaluated comparatively, as antimicrobials. | 2015 | 26668657 |
| choleoeimeria salaselensis sp. n. (apicomplexa: eimeriidae) from the gall bladder of the horned viper cerastes gasperettii (serpentes: viperidae) in saudi arabia. | oocyst morphology and endogenous developmental stages are described for choleoeimeria salaselensis sp. n. from the gall bladder of 10 horned vipers, cerastes gasperettii leviton and anderson, in saudi arabia. sporulated oocysts are ellipsoidal, 23 x 15 (22-25 x 14-17) microm, length/width ratio (l/w) 1.5 (1.4-1.6), each with 4 sporocysts (eimeria-like), but lack a micropyle, polar granules and oocysts residuum. sporocysts are ellipsoidal, 8 x 5 (7-9 x 5-) microm, l/w 1.5 (1.4-1.6), and stieda, s ... | 2014 | 25065125 |
| ecological aspects of the horned viper, cerastes cerastes gasperettii in the central region of saudi arabia. | feeding ecology of any species can help us to understand its natural history, ecological requirements and approaches involved in searching for food. feeding ecology and sexual dimorphism in the horned viper, cerastes cerastes gasperetti collected from the al-thumama area, central region of saudi arabia was described. the gut content of cerastes c. gasperetti mainly consisted of rodents (70%) in addition to arthropods (15%) and lizards (10%). least sexual size dimorphism was noticed in the specie ... | 2016 | 26858550 |
| reproductive biology of the horned viper, cerastes cerastes gasperettii in the central region of saudi arabia. | the reproductive biology of the horned viper, cerastes cerastes gasperettii, in riyadh region of saudi arabia was investigated over a period of one year. study of reproductive cycle of male and female c. c. gasperettii revealed that the breeding season is relatively short (april and may). thereafter females laid eggs by mid of july and hatching probably had taken place by the end of september. no activity was observed during winter, this may indicate just a single clutch per year. relative testi ... | 2015 | 25972758 |
| light and scanning electron microscopical examination of the third stage larva of physocephalus dromedarii (nematoda: spirocercidae)--an abomasal nematode of the one humped camel (camelus dromedarius). | the life cycle of physocephalus dromedarii was studied under experimental conditions. larvae obtained from naturally infected scarabaeus cristatus and aphodius sp. (coleoptera: scarabaeidae) were measured and examined in light and scanning electron microscopy and used to infect a dromedary as final host as well as chicken, mice and a toad as possible paratenic hosts. larvae with the same morphology and similar measurements were found in naturally infected reptiles (trapelus flavimaculatus, eryx ... | 2015 | 25687524 |
| snake bite envenomation in riyadh province of saudi arabia over the period (2005-2010). | the present investigation is a retrospective review of snake bites in riyadh province over the period (2005-2010). a total of 1019 cases of bites admitted to the ministry of health medical centers in riyadh province were analyzed on the basis of age, sex, time of bite and its site on the body, outcome of treatment, antiserum dose and type of snake. bites occurred throughout the six years with the highest frequency in 2005 and least in 2006 where most of the bite cases were mild and all evolved t ... | 2015 | 25737653 |
| identification and phylogeny of arabian snakes: comparison of venom chromatographic profiles versus 16s rrna gene sequences. | identification of snake species is important for various reasons including the emergency treatment of snake bite victims. we present a simple method for identification of six snake species using the gel filtration chromatographic profiles of their venoms. the venoms of echis coloratus, echis pyramidum, cerastes gasperettii, bitis arietans, naja arabica, and walterinnesia aegyptia were milked, lyophilized, diluted and centrifuged to separate the mucus from the venom. the clear supernatants were f ... | 2014 | 25313278 |
| eimeria gasperettii n. sp. (apicomplexa: eimeriidae) from the horned viper, cerates cerastes gasperettii in saudi arabia. | eimeria gasperettii n. sp. is described from the gall bladder of the horned viper, cerastes cerastes gasperettii from al-thumamah, central region of saudi arabia. sporulated oocysts are ellipsoid in shape, measuring 38.8 x 25.5 (29-41 x 17.2-28.4) microm with smooth brownish-yellow bilayered wall, 1.7(1.5-2.0) microm.thick. micropyle polar granule and oocyst residuum are absent. sporocysts are ellipsoid reaching 13.8 x 9.6 (11-14.5 x 8.0-10.3) microm. sporocyst residuum is present. the sporocyst ... | 2003 | 14708848 |
