Researchers at the Centers for Disease Control and Prevention (CDC) and the University of Nebraska Medical Center (UNMC) have reported the first case of cephalosporin-resistant Salmonella bacteria to have developed within the United States.
The new pattern of resistance was detected in a boy living in a farm area where two cattle herds were infected with several strains of Salmonella. Researchers said they are not certain how the child acquired the infection but that public health surveillance has not uncovered additional cases in Nebraska. Officials from the CDC said organisms with a similar resistance pattern have been imported into the United States, but that this case was the first to have developed domestically.
