O 129

03/01/2001 - "In a study conducted during December 1991-September 1993, two of 7,058 V. cholerae strains, obtained from patients suspected to have cholera in the State of Ceará, northeast Brazil, were resistant to 150 micrograms of the vibriostatic agent O/129 (2,4-diamino-6,7-diisopropylpteridine). "
08/01/1996 - "From July 24 to September 17, the Bioforce laboratory (French army) carried out 396 coprocultures : it isolated 78 strains of cholera (Vibrio cholerae 01, biotype El Tor, serotype Ogawa, resisting at O129, without indole), and 77 strains of shigella (Shigella dysenteriae type 1). "
11/01/1985 - "Because of its important consequences on prophylaxis and therapy of cholera and on bacterial identification, we have studied the genetic basis of cross-resistance to trimethoprim and O/129 of strains of Vibrio cholerae O1 independently isolated in Africa. "
10/01/1997 - "However, subsequently, isolates that were CAMP hemolysin negative and susceptible to TMP-SMX and O/129 were increasingly encountered, with all the 1996 isolates being so, which suggested that these properties can no longer be used for the presumptive diagnosis of O139 cholera. "
10/01/1997 - "All early isolates were CAMP hemolysin positive and resistant to the vibriostatic compound O/129 and TMP-SMX, the two properties that could be used for the presumptive diagnosis of O139 cholera. "

06/01/1992 - "Isolation of vibriostatic agent O/129-resistant Vibrio cholerae non-O1 from a patient with gastroenteritis."

03/01/2001 - "Vibrio cholerae resistant to 2,4-diamino-6,7-diisopropylpteridine (O/129) isolated from patients with enteritis in Ceará, Brazil."

02/01/1998 - "Nonagglutinating strains exhibited no resistance to the O129 agent and to the tested antibiotics, they were all negative for virulence cassette, except for one strain with the ctxA and zot genes isolated from a patient with diarrhea, and there was a great variability of ribotypes among these strains. "

03/01/1992 - "Of the 110 consecutive isolates of Vibrio cholerae recovered from cholera patients admitted to the Infectious Diseases Hospital, Calcutta, India, between July 1989 and October 1990, 90 and 82.7% were resistant to 10 and 150 micrograms of 2,4-diamino-6,7-diisopropylpteridine (O/129), respectively.
