Abstract

Background: Enteric fever is a major public health problem in India. The current treatment of choice is the fluoroquinolones.
Methods: The minimum inhibitory concentration (MIC) of ciprofloxacin was determined by E-test, HIMEDIA HiComb MIC test and agar dilution.
Results: An isolate of Salmonella enterica serovar Typhi (S. Typhi) from a case of enteric fever gave a ciprofloxacin MIC of 64μg/ml.
Conclusions: To our knowledge there have been no reports of such high-level resistance to ciprofloxacin in S. Typhi from southern India. HIMEDIA HiComb MIC test method is an alternative to the E-test. Ciprofloxacin resistant typhoid fever responds to treatment with ceftriaxone.
