Retrospective analysis of the emergence of antibiotic-resistant Salmonella enterica infections in a level IV hospital from Lima, Peru.

This study retrospectively analysed the emergence of multidrug-resistant Salmonella enterica in a level IV hospital in Lima, Peru. A total of 64 S. enterica from January 2009 to June 2010 (Period 1, 24 isolates) and January 2012 to December 2014 (Period 2, 40 isolates) were included. Some 25 were from non-hospitalized and 39 from hospitalized patients. Antimicrobial susceptibility to 15 antimicrobial agents was established by automated methods. Most of the isolates were from blood (46.9%), urine (21.9%) and faeces (14.1%). There was a reduction in blood isolates in Period 2, while all the faecal isolates were from this period. In Period 1, only 3/24 (12.5%) isolates showed antibiotic resistance, whereas 25/39 isolates (64.1%) from Period 2 were antibiotic-resistant, with multidrug-resistant and extensively drug-resistant rates of 17.9% and 20.5%, respectively. Multidrug-resistant/extensively drug-resistant Salmonella isolates were introduced in the hospital in 2013, with Salmonella recovered from faeces from non-hospitalized patients suggested an increase in community-acquired multidrug-resistant/extensively drug-resistant Salmonella infections.
