“…In no instance, therefore, was the diagnosis of Escherichia established only on a positive result in the SAA test. Further, the SAA test was positive with all the 68 motile and aerogenic, slow lactose-fermenting Escherichia strains tested and also with all the other 57 prompt lactose-fermenting Escherichia strains originating from diarrhoeal cases, which belonged to certain determined 0-antigen groups and which were described previously (Costin, 1964).…”

SUMMARYThe chemically defined medium with sodium acetate as sole carbon source (sodium acetate agar) devised by Trabulsi & Ewing (1962) was used to examine 414 strains of Shigella and 446 strains of Escherichia. None of the 414 Shigella cultures (belonging to the subgroups, A, B, C, D) utilized acetate and did not develop on sodium acetate agar, whereas about 95% of 283 anaerogenic and non-motile and all 163 aerogenic Escherichia isolates studied, utilized sodium acetate and grew on sodium acetate agar. It is concluded that the utilization of acetate on sodium acetate agar has a definite value for the differentiation of strains of the genera Shigella and Escherichia.

“…From the results obtained with the sodium acetate agar test in other groups of Enterobacteriaceae, only those of some Salmonella strains are included in Table 1 for comparison ; the strains of Salmonella gallinarum-pullorum were all of avian origin (see Costin et al 1964).…”

SUMMARYThe results of the identification of 1079 reference strains of Gram-negative, aerobic, rod-shaped bacteria by a probabilistic method in a computer are given.Comparison of identification by conventional methods and by computer showed that 90.8 % of fermentative and 82.1 % of non-fermentative strains could be identified on the best available probability matrix. Many of these strains were atypical and had caused difficulty in identification in the medical diagnostic laboratory. The implications of various factors in successful computer identification are discussed and the results are given for each taxon by genus and species.
