The aerobic gram negative faecal flora of 78 reptiles consisting of 46 species (39 lizards of 23 species, 15 tortoises of 9 species, and 24 snakes of 14 species) was studied. Salmonella was found to be present in 50% of lizards, in 16% of tortoises and in 16% of snakes. There were altogether 15 different serotypes. Edwardsiella tarda was isolated in 20% of tortoises, in 12% of snakes but only in 3% of lizards. Tortoises represent therefore the possible normal habitat of Edwardsiella tarda. The authors isolated Arizona especially from snakes as described by many authors. A new serotype (Arizona 26a, 26b:27-21=S.arizonae 61:Z10:Z35) was found in a rattlesnake. Also found were large amounts of Citrobacter (52%), E.coli (50%), Proteus mirabilis (49%), Proteus morganii (18%), Proteus rettgeri (26%), and Proteus vulgaris (32%). Klebsiella and Enterobacter seem to prefer the lizards. The overwhelming majority of the studied bacteria were lactose negative, corresponding to the inability of reptiles producing lactose. The normal habitat of Salmonellae in reptiles and the high phylogenetic age of reptiles allows the hypothesis that salmonellae could have a similar old age as their host animals, because the ecological niche, i.e., the bowel of reptiles, has not changed for some hundred million years.
