| sarcocystis atheridis sp. nov., a new sarcosporidian coccidium from nitsche's bush viper, atheris nitschei tornier, 1902, from uganda. | transmission experiments were performed to elucidate the life cycle of a sarcocystis sp. found in a nitsche's bush viper, atheris nitschei nitschei (serpentes: viperidae), from uganda. sporocysts measuring 10.4 (10.0-11.0) x 8.0 (7.0-8.5) microm were given to laboratory mice (crl: cd1), laboratory rats (wistar h), and barbary striped mice, lemniscomys barbarus. sarcocysts developed in the skeletal muscles of laboratory mice and l. barbarus. no sarcocyst was observed in laboratory rats. merogony ... | 1999 | 10431745 |
| molecular characterization of three novel phospholipase a₂ proteins from the venom of atheris chlorechis, atheris nitschei and atheris squamigera. | secretory phospholipase a₂ (spla₂) is known as a major component of snake venoms and displays higher-order catalytic hydrolysis functions as well as a wide range of pathological effects. atheris is not a notoriously dangerous genus of snakes although there are some reports of fatal cases after envenomation due to the effects of coagulation disturbances and hemorrhaging. molecular characterization of atheris venom enzymes is incomplete and there are only a few reports in the literature. here, we ... | 2016 | 27258312 |
| cloning and characterisation of three novel disintegrin precursors from the venoms of three atheris species: atheris chlorechis, atheris nitschei and atheris squamigera. | snake venom constitutes one of the most complex mixtures of naturally-occurring toxic proteins/polypeptides and a large number of these possess very profound biological activities. disintegrins, that are commonly found in viper venoms, are low molecular weight proteins that usually contain an -arg-gly-asp- (-rgd-) motif that is known to be involved in cell adhesion ligand recognition, binding specifically to cell surface integrin receptors and also exhibiting platelet anti-aggregation activity. ... | 2013 | 23732124 |
| scid mice as a tool for evaluation of heteroxenous life cycle pattern of caryospora (apicomplexa, eimeriidae) species. | adult severe combined immunodeficient (scid) mice were inoculated with oocysts of 13 different caryospora (protozoa, apicomplexa) species isolated from the faeces of 10 reptilian and three raptorial bird hosts in attempt to test heteroxenous life cycle pattern. only three reptilian isolates originated from viperid snakes, namely from calloselasma rhodostoma, atheris nitschei and vipera ursinii induced lethal dermal caryosporosis in scid mice. neither clinical signs nor developmental stages were ... | 2000 | 10962156 |
| envenomation by the great lakes bush viper (atheris nitschei). | we present a case of envenomation by a great lakes bush viper, atheris nitschei. atheris species are a group of snakes that are indigenous to the forested areas of central africa. prior reports of envenomation by great lakes bush vipers were not found in a medline search. however, reports of other atheris species envenomations describe coagulopathy and acute renal failure. | 2013 | 23327286 |
