Am. Ciraj et al., Copper resistance & its correlation to multiple drug resistance in Salmonella typhi isolates from south Karnataka, I J MED RES, 110, 1999, pp. 181-182
A study was conducted to ascertain the prevalence of copper resistant Salmo
nella typhi isolates in south Karnataka. Of the 186 strains studied, 26 (13
.97%) were found to be copper resistant. Among the copper resistant strains
19 (73.08%) were found multi drug resistant. All copper resistant strains
remained uniformly sensitive to ceftriaxone, ciprofloxacin and norfloxacin.
Multiple drug resistance was exclusively associated with El phage types.
