| epizootic of fatal amebiasis among exhibited snakes: epidemiologic, pathologic, and chemotherapeutic considerations. | an epizootic of reptilian amebiasis seems to have caused the death of 15 to 16 large and valuable captive snakes (boas, pythons, and anacondas) occupying one of 5 large display dioramas in the steinhart aquarium of the california academy of science, golden gate park, san francisco. subsequent review of previous snake deaths in the colony indicated that of 464 snakes that had died since early 1969, 89 snakes had intestinal or hepatic lesions, and 80 of these snakes had pathologic features which i ... | 1975 | 1147335 |
| innate defensive behaviour and panic-like reactions evoked by rodents during aggressive encounters with brazilian constrictor snakes in a complex labyrinth: behavioural validation of a new model to study affective and agonistic reactions in a prey versus predator paradigm. | defensive behaviour has been extensively studied, and non-invasive methodologies may be interesting approaches to analyzing the limbic system function as a whole. using experimental models of animals in the state of anxiety has been fundamental in the search for new anxiolytic and antipanic compounds. the aim of this present work is to examine a new model for the study of affective behaviour, using a complex labyrinth consisting of an arena and galleries forming a maze. furthermore, it aims to c ... | 2007 | 17604117 |
