Abstract

Introduction: The increasing antimicrobial resistance of Salmonella isolates is of major public health concern, but information regarding these aspects is still lacking in Romania. This study focused on a detailed and accurate investigation concerning prevalence, serotypes, and antimicrobial resistance patterns of Salmonella strains, isolated from pork and chicken meat, collected from all regions of Romania in 2011.

Methodology: The research was conducted on 650 samples of chicken and pork meat collected from production units and retail markets located in various regions of Romania. A total of 149 Salmonella isolates were recovered (22.92%), serotyped, confirmed by PCR, and further tested for antimicrobial susceptibility.

Results: Thirteen Salmonella serovars were identified; predominant serovars included Infantis, Typhimurium, Derby and Colindale. Multiple resistance was found in 83.22% (n = 124) of the isolates. The isolates were frequently resistant to tetracycline (80.53%), streptomycin (81.21%), sulfamethoxazole (87.25%), nalidixic acid (65.10%), and ciprofloxacin (42.95%). Additionally, a markedly lower resistance rate was observed for ampicillin (20.81%), chloramphenicol (16.78%), and ceftazidime (11.41%). Among 137 resistant Salmonella isolates, 35 different resistance patterns were found.

Conclusion: A high prevalence of Salmonella spp. and a relatively high resistance rate to multiple antimicrobials was found. This data indicates that chicken and pork meat could constitute a source of human exposure to multidrug-resistant Salmonella and therefore could be considered a potential vehicle of resistant Salmonella foodborne diseases. Further actions are needed to succesfully implement a national surveillance program for better monitoring of these resistant pathogens.
