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. Additionally, all O/129-resistant strains of V. cholerae were multiply resistant to antimicrobial agents. Except in the cases of four strains, resistance to O/129 was invariably linked with resistance to co-trimoxazole. Although O/129 susceptibility is still a useful test for Vibrio identification, resistance of V. cholerae to this compound in local areas might occasionally pose a problem.
在1989年7月至1990年10月期间从印度加尔各答传染病医院收治的霍乱患者中连续分离出的110株霍乱弧菌中,分别有90株(占82.7%)对10微克和150微克的2,4-二氨基-6,7-二异丙基蝶啶(O/129)耐药。此外,所有对O/129耐药的霍乱弧菌菌株对多种抗菌药物均耐药。除了4株菌株外,对O/129的耐药性总是与对复方新诺明的耐药性相关。尽管O/129敏感性仍是鉴定弧菌的一项有用试验,但当地霍乱弧菌对该化合物的耐药性偶尔可能会带来问题。
