“…This finding is in accordance with studies from other countries [12,15]. The prevalence of Salmonella isolates resistant to nalidixic acid was lower than the one reported by Shrestha et al (2010) in Nepal [28].…”

“…Different prevalence rates of Salmonella spp. in food, especially poultry and poultry products, have been reported by different authors [12][13][14][15][16][17]. Salmonella contamination rates observed in our country are relatively high (22.92%) and confirm the widespread contamination of pork and chicken meat with Salmonella spp.…”

“…However, the resistance rate is higher than the one reported by Yan et al (2010) [15], Chao et al (2007) [33], and Thong and Modarressi (2011) [12]. Concerning food-borne Salmonella, the resistances of most concern are those against quinolones and cephalosporins, both of which are mentioned in the WHO list of critically important antibiotics for human medicine [5].…”

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.

“…This level was comparable to that reported by Bouchrif et al (2009) in Morocco (44%) and Van et al (2007) in Vietnam (34%) but much lower than the level reported by Thong and Modarressi (2011) in Kuala Lumpur (67%). Among all Salmonella isolates from different sources, 37 antibiotic resistance patterns were detected, indicating wide spread multidrug resistance.…”

“…Certain plasmid sizes may be responsible for resistance to particular antibiotics (White et al, 2001). Resistance to ampicillin in Salmonella was mediated by a β-lactamase gene carried on a plasmid (Thong & Modarressi, 2011). Since some of the isolates were resistant to one or more antibiotics and yet did not harbour any plasmid, the antibiotic resistance might be chromosomally mediated or mediated by other mobile elements such as transposons (Yah & Eghafona, 2008).…”
