| ticks (acarina: ixodidae) of reptiles from central, lusaka and southern provinces of zambia. | during the period 1988-1991, reptiles (23 snakes, 36 tortoises, 25 chameleons and 2 monitor lizards) from central, lusaka and southern provinces of zambia were caught and checked for ticks. only 2 snakes, respectively one python sebae (gmelin, 1789) and one bitis arietans (merrem, 1820), 8 tortoises, respectively seven geochelone pardalis (bell, 1828) and one kinixys belliana (gray, 1831) were found infested with a small number of ticks: nymphs and adults of aponomma latum (koch, 1844) and ambly ... | 1993 | 8065818 |
| pentastomes (pentastomida, armillifer armillatus wyman, 1848) in snakes from zambia. | twenty-three snakes, belonging to eight different species, were collected from rural areas of zambia and inspected for the presence of pentastomes. pentastomid parasites were found in four snakes: one african rock python (python sebae), one puff adder (bitis arietans) and two mozambique spitting cobras (naja mossambica) were infested with a small number of armillifer armillatus, respectively five, two and one adult parasites. as humans can be incidental/intermediate hosts for reptilian pentastom ... | 1999 | 10870563 |
| tsetse fly blood meal modification and trypanosome identification in two sleeping sickness foci in the forest of southern cameroon. | the blood meal origins of 222 tsetse flies (213 glossina palpalis palpalis, 7 glossina pallicera pallicera, one glossina nigrofusca and one glossina caliginea) caught in 2008 in two human african trypanosomiasis foci (bipindi and campo) of south cameroon were investigated. 88.7% of tsetse flies blood meals were identified using the heteroduplex method and the origin of the remaining blood meals (11.3%) was identified by sequencing the cytochrome b gene. most of the meals were from humans (45.9%) ... | 2010 | 20541513 |
| a novel protein from the serum of python sebae, structurally homologous to +¦-phospholipase a2 inhibitor, displays antitumor activity. | cytotoxic and antitumors factors have been documented in the venom of snakes, while little information is available on the identification of cytotoxic products in the snake serum. in this study, we purified and characterized a new cytotoxic factor from serum of the non venomous phyton sebae, endowed with antitumor activity. the serum of the p. sebae, termed pss, exerted a cytotoxic activity and reduced dose dependently the viability of several different tumor cell lines. in a model of human squa ... | 2011 | 21834793 |
| molecular identification of cryptosporidium species from pet snakes in thailand. | cryptosporidium is an important pathogen causing gastrointestinal disease in snakes and is distributed worldwide. the main objectives of this study were to detect and identify cryptosporidium species in captive snakes from exotic pet shops and snake farms in thailand. in total, 165 fecal samples were examined from 8 snake species, boa constrictor (boa constrictor constrictor), corn snake (elaphe guttata), ball python (python regius), milk snake (lampropeltis triangulum), king snake (lampropeltis ... | 2016 | 27658593 |
| in situ cardiac perfusion reveals interspecific variation of intraventricular flow separation in reptiles. | the ventricles of non-crocodilian reptiles are incompletely divided and provide an opportunity for mixing of oxygen-poor blood and oxygen-rich blood (intracardiac shunting). however, both cardiac morphology and in vivo shunting patterns exhibit considerable interspecific variation within reptiles. in the present study, we develop an in situ double-perfused heart approach to characterise the propensity and capacity for shunting in five reptile species: the turtle trachemys scripta, the rock pytho ... | 2016 | 27207643 |
| initiation and patterning of the snake dentition are dependent on sonic hedgehog signaling. | here we take the first look at cellular dynamics and molecular signaling in the developing snake dentition. we found that tooth formation differs from rodents in several respects. the majority of snake teeth bud off of a deep, ribbon-like dental lamina rather than as separate tooth germs. prior to and after dental lamina ingrowth, we observe asymmetries in cell proliferation and extracellular matrix distribution suggesting that localized signaling by a secreted protein is involved. we cloned son ... | 2008 | 18456251 |
| embryonic development of python sebae - ii: craniofacial microscopic anatomy, cell proliferation and apoptosis. | this study explores the microscopic craniofacial morphogenesis of the oviparous african rock python (python sebae) spanning the first two-thirds of the post-oviposition period. at the time of laying, the python embryo consists of largely undifferentiated mesenchyme and epithelium with the exception of the cranial base and trabeculae cranii, which are undergoing chondrogenesis. the facial prominences are well defined and are at a late stage, close to the time when lip fusion begins. later (11-12d ... | 2007 | 17499982 |
| embryonic development of python sebae - i: staging criteria and macroscopic skeletal morphogenesis of the head and limbs. | this study explores the post-ovipositional craniofacial development of the african rock python (python sebae). we first describe a staging system based on external characteristics and next use whole-mount skeletal staining supplemented with computed tomography (ct) scanning to examine skeletal development. our results show that python embryos are in early stages of organogenesis at the time of laying, with separate facial prominences and pharyngeal clefts still visible. limb buds are also visibl ... | 2007 | 17499493 |

| traditional medicinal animal use by xhosa and sotho communities in the western cape province, south africa. | the use of animals and animal-derived materials in traditional medicine constitutes an important part of the belief systems of indigenous african cultures. it is believed to be rapidly expanding in south africa, where traditional healers are estimated to outnumber western doctors by 2000:1 in some areas, with an overall clientele consisting of 60-80% of south african citizens. despite concerns about the impact of the trade in traditional medicine on biodiversity, there has been only limited rese ... | 2019 | 31288841 |
| squamate reptiles from kanapoi: faunal evidence for hominin paleoenvironments. | the squamate fossil record from kanapoi reveals generic to higher-order similarities with modern east african herpetofaunas. the record is derived from surface collection and screen washing, and consists primarily of isolated vertebrae with a few maxillary and mandibular elements. the most abundant remains are vertebrae of large-bodied python that are morphologically similar to extant python sebae, and vertebrae of varanus cf. (varanus niloticus + varanus exanthematicus). additional cranial and ... | 2020 | 29910043 |
| haemogregarine genetic diversity in captive african rock pythons from nigeria suggests a geographical pattern. | understanding the processes that drive parasite diversification, distribution, and abundance is central to disentangle the dynamics and evolution of diseases. in this study, we screened african rock pythons from nigeria for the presence of blood parasites to assess their distribution, diversity, and phylogenetic relationships. | 2018 | 29780016 |
| hematological and plasma chemistry values for the african rock python (python sebae). | hematology and plasma biochemistry parameters are useful in the assessment and management of threatened and endangered species. although reference values are readily available for many mammalian species, reference values for snakes are lacking for most species. we determined hematology and plasma biochemistry values for captive african rock pythons (python sebae) and studied the effects of age, sex, season and hemoparasites on these values. blood (5 ml) was collected by venipuncture of ventral c ... | 2017 | 30255069 |
