Atypical, fljB-NegativeSalmonella enterica subsp. entericaStrain of Serovar 4,5,12:i:? Appears To Be a Monophasic Variant of Serovar Typhimurium

摘要

An fljB-negative, multidrug-resistantSalmonella enterica serovar 4,5,12:i:? phage type DT U302 strain (resistant to ampicillin, chloramphenicol, sulfonamide, gentamicin, streptomycin, tetracycline, and sulfamethoxazole-trimethoprim) emerged and spread in Spain in 1997. Sequences specific for Salmonella serovar Typhimurium and phage type DT 104 and U302 were present in this atypicalSalmonella strain, suggesting that it is a monophasicSalmonella serovar Typhimurium variant.
