Versuche der Experimentalinfizierung von Schlangen <i>Vipera ammodytes ammodytes</i> mit Salmonella- und Arizonabakterien

Evolution of Host Adaptation in Salmonella enterica

“…The capability of S. bongori or S. enterica subspecies II, IIIa, IIIb, IV, VI, and VII serotypes to survive in macrophages of poikilothermic animals has not been studied. Experimental oral exposure of snakes, turtles, or lizards to isolates of S. enterica subspecies I, II, or III resulted in all cases in no overt signs of disease and no colonization of organs other than the intestinal tract (35)(36)(37)111). It has therefore been speculated that Salmonella serotypes evolved in the alimentary tract of reptiles, where they developed from pathogens into commensal organisms (87,102).…”

Salmonella septicaemia in a smooth snake

“…Empirical and anecdotal evidence suggests that S Arizonae can be associated with different clinical manifestations including high mortality in captive European vipers, especially in nosehorned vipers (Vipera ammodytes ammodytes) (Dimow and Slawtschew 1967). The case described here reports bacterial infection in a smooth snake and a case of septicaemic salmonellosis in a European colubrid snake.…”

Transovarian passage, visceral distribution, and pathogenicity of salmonella in snakes

“…Salmonella gastroenteritis and septicemia have been described; in all cases, poor husbandry, maladaptibility, and malnutrition may have been predisposing factors (3). Experimental infections in snakes (7), tortoises (5), and t Contribution no. 918, Storrs Agricultural Experiment Sta-tion, University of Connecticut, Storrs, Conn. lizards (6) by oral, subcutaneous, intracardiac, and intraperitoneal inoculations have all failed to produce disease.…”
