“…Lower rates (62%-65%) were mentioned in a number of studies focused on these specific strains [24,25] while higher rates of 84%-97% were mentioned less frequently [26]. Other studies concluded that this resistance prevalence for tetracycline and streptomycin is due to their frequent administration in veterinary medicine [27].…”

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.

“…Since 2001, there has been no report of a gastroenteritis outbreak in Sergipe. The few reports available on Enteritis outbreaks in Brazil are from the Southern states of Brazil (12) (13) . However, reduced numbers do not always represent a real decrease in the number of outbreaks, but instead could representative of under reporting of the outbreaks.…”

Introduction:In December 2001, an outbreak of foodborne gastroenteritis infected 114 of 161 people who ate at a restaurant in Aracaju, State of Sergipe, Brazil. Methods: The epidemiological and microbiological aspects of the outbreak were characterized. Results: Potato salad made with homemade mayonnaise and stored at unsuitable temperatures was associated with increased risk of foodborne infection. Salmonella Enteritidis was isolated from the diarrheal stools of the hospitalized patients, and genotyping of the fecal samples generated identical randomly amplifi ed polymorphic deoxyribonucleic acid (DNA) profi les. Conclusions: To the best of our knowledge, this is the fi rst and the only record of a gastrointestinal outbreak in Sergipe.

“…During the last decade, in RS, the resistance of S. Enteritidis isolated from foodborne illnesses has been the subject of several studies [8,11,[13][14][15]. Several drugs have been analyzed, and the S. Enteritidis responsible for salmonellosis in RS showed an increased resistance to AMP and especially to NAL [3,11]. Between the years 1999 and 2006, S. Enteritidis isolates showed a gradual increase in resistance to NAL [8,11,14].…”

“…Salmonella is one of the main causative agents of foodborne disease (FBD) worldwide; it is responsible for serious health problems and significant economic losses [1][2][3]. In many countries, including in Brazil, foods of animal origin have been identified as the primary vehicles for human salmonellosis.…”

Introduction: Previous studies have identified Salmonella as the main causative agent of foodborne diseases in the state of Rio Grande do Sul (RS), southern Brazil, between 1997 and. This study aimed to describe the Salmonella serotypes, antimicrobial patterns, and food vehicles of salmonellosis that occurred in RS between 2007 and 2012. Methodology: Information about Salmonella isolates and salmonellosis outbreaks registered in the official records of the Central Laboratory of RS (FEEPS/IPB-LACEN/RS) was analyzed. Results: Among the 163 isolates investigated, 138 (84.7%) were identified as S. Enteritidis. The second and third most frequent serovars identified were S. Schwarzengrund (5.5%) and S. Typhimurium (3.7%). Homemade mayonnaise was the food vehicle most frequently identified (17.39%), followed by pastry products (15.94%) and beef (12.32%). Antimicrobial resistance was analyzed; 12 drugs were tested. Higher percentages of resistance were observed to nitrofurantoin (94.2%) and nalidixic acid (89.1%). The resistance to these two drugs was verified in 80.43% of the isolates. Multi-resistance to three and five drugs was verified in four and two isolates, respectively. Conclusions: Comparing the results of the present study with results of previous reports, it was possible to conclude that S. Enteritidis and homemade mayonnaise are still the main serotype and food vehicle of salmonellosis in RS and that antimicrobial resistance has been increasing among S. Enteritidis responsible for foodborne outbreaks in southern Brazil.
