    Abstract:
    With the emergence of multidrug-resistant nontyphoidal (NT) Salmonella, knowledge of resistance patterns is critical for appropriate presumptive treatment. This report describes the prevalence and trends of NT Salmonella antimicrobial susceptibility within the New York State (NYS) Foodborne Diseases Active Surveillance Network (FoodNet). The NYS Department of Health, Wadsworth Center Public Health Laboratory tested all Salmonella isolates from the NYS FoodNet catchment area between May 2003 and December 2007 for antimicrobial susceptibility to ampicillin, chloramphenicol, streptomycin, sulfisoxazole, tetracycline, nalidixic acid, and ciprofloxacin. Isolate susceptibility results were linked to their corresponding demographic and clinical data and analyzed. Multidrug-resistant isolates were defined as resistant to ampicillin, chloramphenicol, streptomycin, sulfisoxazole, and tetracycline (R-type ACSSuT). Antimicrobial susceptibility for 2189 FoodNet cases (98.5% of total cases) showed 79.6% pansusceptible, 6.9% R-type ACSSuT, and 13.5% resistant to at least one antimicrobial agent but not R-type ACSSuT. Four (0.2%) isolates were resistant to ciprofloxacin. From 2004 to 2007, cases with R-type ACSSuT significantly decreased from 8.7% (37/424) to 4.8% (24/499) (p < 0.01). Serotypes with the highest proportion of R-type ACSSuT included Salmonella Typhimurium 17.9% (79/444), and Salmonella Newport 29.1% (51/175). Among Salmonella Typhimurium isolates, over 40% of the African-American cases (19/46) had R-type ACSSuT isolates, compared with 15.7% of the Caucasian cases (58/369) (p < 0.01). R-type ACSSuT Salmonella Typhimurium cases were hospitalized (41.8%) more frequently than pansusceptible Salmonella Typhimurium cases (24.9%), after controlling for age (p < 0.05). Length of hospitalization was not significantly different. Although R-type ACSSuT NT Salmonella has decreased since 2003 within the NYS FoodNet catchment area, monitoring resistance patterns remains important in identifying emerging resistant strains, vulnerable populations, and determining appropriate presumptive treatment regimens. The higher rate of R-type ACSSuT among the African-American cases requires further study.
