Isolation of Salmonella enterica Serovar Kentucky Strain ST 198 and Its H ₂ S-Negative Variant from a Patient: Implications for Diagnosis

Abstract

H2S-producing multiresistant Salmonella enterica serovar Kentucky strain sequence type (ST) 198 and its non-H2S-producing variant were isolated from a patient. Whole-genome comparison showed a base addition in the gene encoding molybdenum cofactor biosynthesis protein C, which could affect H2S production in the variant. Lack of H2S production has implications for diagnosis of salmonella.
