Transferable drug resistance in Salmonella senftenberg

Six Salmonella senftenberg strains were isolated from blood samples of patients clinically diagnosed to be suffering from enteric fever during the recent outbreak of enteric fever in and around Calcutta. All of them were multidrug resistant including chloramphenicol. The minimum inhibitory concentration (MIC) of the drugs in which they were resistant, were well above the normal level. All these strains were sensitive to cephalexin, gentamicin, furazolidone and ciprofloxacin. The transferable drug resistance test suggested that the strains were carrying transferable drug resistant gene containing ACSTK resistant factor.
