''Cedecea'' is a genus of extremely rare bacteria of the family Enterobacteriaceae. The name of this genus was derived from CDC, the abbreviation for the Centers for Disease Control where the initial members of this genus were discovered. This genus resembles no other group of Enterobacteriaceae.〔Grimont, P. A. D., Grimont, F., Farmer III, J. J., and Asbury, M. A. (1981). (''Cedecea davisae'' gen. nov., sp. nov. and ''Cedecea lapagei'' sp. nov., New ''Enterobacteriaceae'' from clinical specimens. ) ''International Journal of Systematic Bacteriology'' 31, 317-326.〕 ''Cedecea'' bacteria are Gram-negative, bacillus in shape, motile, nonencapsulated, and nonspore-forming.〔Mawardi, H., Pavlakis, M., Mandelbrot, D., Woo, S. B. (2010). ( Sirolimus oral ulcer with ''Cedecea davisae'' superinfection. ) ''Transpl Infect Dis'' 12, 446-450.〕〔Abate,G., Qureshi, S., and Mazumder, S. A. (2011). (''Cedecea davisae'' bacteremia in a neutropenic patient with acute myeloid leukemia. ) ''Journal of Infection'' 63, 83-85.〕 The strains of ''Cedecea'' appear to be similar to those of ''Serratia''. Both ''Cedecea'' and ''Serratia'' are lipase positive and resistant to colistin and cephalothin; however, ''Cedecea'' is unable to hydrolyze gelatin or DNA.〔〔Farmer III, J. J., Sheth, N. K., Hudzinski, J. A., Rose, H. D., Asbury, M. F. (1982). ( Bacteremia due to ''Cedecea neteri'' sp. nov. ) ''Journal of Clinical Microbiology'' 16, 775-778.〕〔Perkins, S. R., Beckett, T. A., Bump, C. M. (1986). ( ''Cedecea davisae'' bacteremia. ) ''Journal of Clinical Microbiology'' 24, 675-676.〕〔Dalamaga, M., Karmaniolas, K., Arsenis, G., Pantelaki, M., Daskalopoulou, K., Papadavid, E., and Migdalis, I. (2008). (''Cedecea lapagei'' bacteremia following cement-related chemical burn injury. ) ''Burns'' 34, 1205-1207.〕 ==History of Genus== ''Cedecea'' bacteria were discovered in 1977 by a group of scientists at the CDC and were initially named “Enteric Group 15”.〔〔〔〔〔Dalamaga, M., and Vrioni, G. (2011). ''Cedecea''. ''Molecular detection of human bacterial pathogens'', 817-825.〕 In 1980, Patrick A. D. Grimont and Francine Grimont proposed the genus name of ''Cedecea'' for this group.〔〔〔〔〔 This particular name was given to "Enteric Group 15" for the abbreviation of the Center for Disease Control (CDC) where the group of bacteria was discovered.〔 At this time, six species have been identified.〔 Currently, three strains have been named while three remain unnamed.〔〔 ''Cedecea davisae'' was named after Betty Davis. Davis is an American bacteriologist who has contributed to serological and biochemical identification of Enterobacteriaceae and Vibrionaceae.〔 ''Cedecea lapagei'' was named after Stephen Lapage, who is a British bacteriologist. Lapage has contributed to bacterial systematics as the editor of ''Bacteriological Code''. Lapage has also made many contributions to the family Enterobacteriaceae.〔 ''Cedecea neteri'' was named after Erwin Neter. Neter is an American microbiologist and physician. Like Davis and Lapage, Neter has contributed to the family Enterobacteriaceae.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Cedecea」の詳細全文を読む スポンサード リンク
