Salmonella enterica serotype choleraesuis causes infections that can require antimicrobial treatment.
Multidrug-resistant strains have been identified, but the antimicrobial ceftriaxone has been effective against them so far.
However, Prof. Ou and colleagues have isolated a strain of Salmonella enterica serotype choleraesuis that is resistant to all antimicrobials commonly used to treat salmonellosis.
The isolated bacterium came from a 58-year-old man with sepsis who subsequently died.
|Drug-resistance was due to changes in the genes of the bacteria.|
The team found that the drug-resistance was due to changes in the genes of the bacteria, including some in a genetic element that can potentially be transmitted between bacteria.
Although this strain was from only 1 patient, the public-health implications of multidrug-resistant Salmonella are serious.
"Constant surveillance is needed to prevent its further spread," warn the authors.
