[Epizootiology of salmonellosis in wild and zoo animals].
To demonstrate a few characteristic features of zoo animals caused by infections, bacterial examination of material collected in Leipzig Zoo Garden was carried out with respect to the presence of Salmonella. Examination of 7022 organ and faeces samples revealed that 350 salmonella isolates could be cultivated. This established 5% presence of salmonella. Among the 3 most important classes of animals exists quite a reasonable difference: 9.9% of all samples taken from animals of reptile-origin revealed the presence of Salmonella, only 6.0% and 4.1% was registered among birds and mammals respectively. 65.4% of all the Salmonella isolates were of serovar typhimurium whereby a clear difference between the animal classes was noted. Among birds 84.2% of the isolates were S. typhimurium, among mammals 62.6%, among reptiles only 26.8%.
