Emendations:
Everett et al. 1999
Everett KD, Bush RM, Andersen AA. Emended description of the order Chlamydiales, proposal of Parachlamydiaceae fam. nov. and Simkaniaceae fam. nov., each containing one monotypic genus, revised taxonomy of the family Chlamydiaceae, including a new genus and five new species, and standards for the identification of organisms. Int J Syst Bacteriol 1999; 49:415-440.
Anonymous. Notification list. Notification that new names and new combinations have appeared in volume 49, part 2 of the IJSB. Int J Syst Bacteriol 1999; 49:937-939. Notes:
Emendation accompanied by the inclusion of 3 families in the order.
In a "Letter to the Editor", several bacteriologists [1] strongly object to the reclassification of the order Chlamydiales proposed by Everett et al. 1999. — See also, the reply by Everett and Andersen [2].
