a survey of blastocystis in reptiles.a total of 28 species of reptiles were investigated for blastocystis using light microscopy and in vitro culture in biphasic egg slant medium. blastocystis species were detected in 8 (28.6%) of these 28 species in 3 tortoises (geochelone elephantopus, g. elegans and g. carbonaria), 3 snakes (boiga dendrophilla, python reticulatus and elaphe radiata), 1 crocodile (crocodylus porosus) and 1 iguana lizard (cyclura cornuta). the reptilian blastocystis appeared to be morphologically similar to b. hom ...19921495927
molecular evidence of sarcocystis species in captive snakes in japan.sarcocystis nesbitti, using snakes as the definitive host, is a causative agent of acute human muscular sarcocystosis in malaysia. therefore, it is important to explore the distribution and prevalence of s. nesbitti in snakes. nevertheless, epizootiological information of s. nesbitti in snakes remains insufficient because few surveys have assessed sarcocystis infection in snakes in endemic countries. in japan, snakes are popular exotic pet animals that are imported from overseas, but the degree ...201526044884

gut bacteria of animals living in polluted environments exhibit broad-spectrum antibacterial activities.infectious diseases, in particular bacterial infections, are the leading cause of morbidity and mortality posing a global threat to human health. the emergence of antibiotic resistance has exacerbated the problem further. hence, there is a need to search for novel sources of antibacterials. herein, we explored gut bacteria of a variety of animals living in polluted environments for their antibacterial properties against multi-drug resistant pathogenic bacteria. a variety of species were procured ...202032124096
the fine structure of the dorsal column nucleus and the nucleus of bischoff of the python (python reticulatus).three types of neuronal perikaryal profiles were identified in the dorsal column nucleus and the nucleus of bischoff of the python (python reticulatus). type i neuronal profiles are large (diameters 12-20 μm) with a deeply indented uncleus. the cisterns of rough endoplasmic reticulum (rer) are mostly randomly dispersed. axosomatic synapses are few. type ii neuronal profiles (9-11 μm) have a smooth, round, or slightly oval nucleus. several small stacks of rer are present. type iii neuronal profil ...198629954162
exotic reptile bites.reptiles are a growing part of the exotic pet trade, and reptile bites have been considered innocuous in the emergency medicine literature. two cases are reported of reptile bites, one from a green iguana and the other from a reticulated python. the treatment concerns associated with reptile bites are discussed.19979270399
akkermansia glycaniphila sp. nov., an anaerobic mucin-degrading bacterium isolated from reticulated python faeces.a gram-stain-negative, non-motile, strictly anaerobic, oval-shaped, non-spore-forming bacterium (strain pytt) was isolated from reticulated python faeces. strain pytt was capable of using mucin as sole carbon, energy and nitrogen source. cells could grow singly, in pairs, and were also found to aggregate. scanning electron microscopy revealed the presence of filamentous structures connecting individual bacterial cells. strain pytt could grow on a limited number of single sugars, including n-acet ...201627499019
the big squeeze: scaling of constriction pressure in two of the world's largest snakes, python reticulatus and python molurus bivittatus.snakes are important predators that have radiated throughout many ecosystems, and constriction was important in their radiation. constrictors immobilize and kill prey by using body loops to exert pressure on their prey. despite its importance, little is known about constriction performance or its full effects on prey. we studied the scaling of constriction performance in two species of giant pythons (python reticulatus and python molurus bivittatus) and propose a new mechanism of prey death by c ...201526347553
effect of snake venom procoagulants on snake plasma: implications for the coagulation cascade of snakes.several snake venoms contain proteinases that activate zymogens in the coagulation cascade and thus exhibit their procoagulant effects. while most procoagulant proteinases from snake venoms are dissimilar to coagulation factors, group d (trocarin, notecarin) and c (pseutarin) prothrombin activators are structural and functional homologues of factor xa and the prothrombinase complex, respectively. we examined the effect of these and other procoagulants from snake venoms as well as mammalian and s ...200211689239
