Abstract

Surveillance of antibiotic resistance of Salmonella isolates from humans in the north-eastern United States has detected resistance to chloramphenicol on 8 occasions, three of which were hospital outbreaks. Resistance was developed during treatment in 5 instances, and in another instance this situation was suspected. On 2 other occasions chloramphenicol-resistant Salmonella appear to have been imported from outside the country. Common features of the cases were multiple antibiotic resistance, transfer of R-factor, simultaneous presence of different patterns of resistance, similar patterns of antibiotic resistance in other intestinal bacteria, and apparent in vivo and in vitro loss of resistance to chloramphenicol with time.
