Analysis to drug resistance of Dysenteric bacilli: A report of 51 cases

Objective: To study the drug resistance of Dysenteric bacilli so as to guide the physicians to choose effective antibiotics.Methods: Dysenteric bacilli were isolated from the stools of 51 patients,and Kirby-Bauer method was used to test their sensitivity to antibiotics.Results: Dysenteric bacilli were highly resistant to sulfamethoxazole(78.4%),ampicillin(60.8%),norfloxacin(29.1%) and ceftriaxone(23.5%),but were sensitive to amikacin(78.4%),phosphonomycins(88.2%),ofloxacin(84.3%),piperacillin(86.3%),cefoperazone(92.2%) and furazolidone(94.1%).Conclusions: Dysenteric bacilli is highly resistant to sulfamethoxazole,ampicillin and norfloxacl,but sensitive to the third generation cephalosporins,phosphonomycins,amikacin and ofloxacin.Furazolidone is another chioce,for its sensitivity to Dysenteric bacilli is greatly increasing.
