The Identity of Bacterium Columbensis Castellani

Abstract

The organism originally isolated by Castellani (1914) from "collumbensis fever" and later (Castellani, 1938) assigned by him to the gentus Salmonella, has been infrequently reported in the Western Hemisphere. The only records that have been located are a note reporting Taylor's (1924) isolation of what is now strain 595 of the American Type Cullltuire Colleetion, the record in the catalogue of that collection mentioning the isolation by Shaw of their strain 4298, and an indirect reference by Jordan and M\IcBroom (1934) to the occurrence of the organism in Panama. The organism has been encountered in Ceylon, in the tropics of Asia and Africa, in the Balkans, and also in ILondon, and reported in the papers of Fernando

Classification, Identification, and Clinical Significance ofProteus,Providencia, andMorganella

“…However, he further contended that there was insufficient evidence to either exclude Proteus rettgeri from the genus Proteus or create this new genus to contain only the Providence group and Proteus rettgeri. He also proposed that the existing genus Morganella, first proposed in 1943 (35), might include the species morganii, rettgeri, and inconstans. Apparently this proposal was never acted upon by the Judicial Commission.…”

“…He called these "Bacterium columbense" after Colombo, the city in Ceylon where he worked, and noted that they were probably neither the paracolon nor paratyphosus D bacteria reported by other workers (Table 3) (14). Many years later, these strains would be classified by Fulton into the genus Morganella (35).…”

“…A major development that occurred in 1943 was the work by Fulton, which showed that "Bacterium columbense"Castellani 1914 was actually the same organism as Proteus morganii Winslow 1919. He proposed the genus name Morganella for these strains, which were negative for the fermentation of lactose or sucrose but produced indole (35). The type species would be M. morganii Morgan 1906, with an additional species, "M.…”

Further Studies on One Anaerogenic Paracolon Organism, Type 29911

“…To include these organisms in the genus Protesw, however, calls for a definite extension of the limitations of the genus which does not seem advisable at the present time. To create new genera and to raise certain genera to family rank in the Enterobadteriaceae as has been suggested (Fulton, 1943;Waldee, 1945;and others) would simplify the immediate problem but could easily confuse future considerations. The position of type 29911 strains appears to be intermediate between the Proteu and the Shigella groups, and at present they can be classified only as transitional forms between these two groups and given neither genus nor species rank.…”

Comparative Distribution and Possible Pathogenicity of Paracolobactrum Species in an Area Highly Endemic for Enteric Infections

“…These organisms are apparently identical with the once-designated SalmoneUla columbensis, recently studied by Fulton (1943). This author studied 18 strains of this biochemical type, the majority of which were obtained from gastroenteritis patients.…”
