Interpreting streptomycin susceptibility test results for Salmonella enterica serovar Typhimurium
Optional Fields
streptomycin Salmonella Typhimurium resistance disk diffusion MIC resistance genotype RESISTANCE ANIMALS DT104
Resistance or susceptibility of Salmonella enterica to streptomycin is widely used as an epidemiological marker. However, there is no clear consensus on the interpretation of streptomycin susceptibility test results. Comparison of results obtained with the Clinical and Laboratory Standards Institute (CLSI) disk diffusion method, the minimum inhibitory concentration (MIC) determined by Etest and streptomycin resistance genotype for 90 isolates of S. enterica serovar Typhimurium suggests that appropriate interpretive criteria for MIC results are susceptible at = 16 mg/L. For CLSI disk diffusion, we propose susceptible at a zone diameter >= 13 mm and resistant at <= 10 mm. (c) 2006 Elsevier B.V. and the International Society of Chemotherapy. All rights reserved.
