“…The resistance rates to ampicillin and chloramphenicol were also higher in S. Typhimurium. This serotype had the highest resistance rates in the world, and the antimicrobial resistance rates in the present study were similar to those found in other countries (12,(22)(23)(24). S. Enteritidis also had higher resistance rates to ampicillin, chloramphenicol, cefotaxime, and TMX.…”

SUMMARY:The study aimed to investigate the prevalence of various serotypes and extended-spectrum b-lactamase-producing features of Salmonella strains and to determine the antimicrobial susceptibility of 256 Salmonella strains other than Salmonella serotype Typhi, which were isolated at 12 university hospitals in Korea. We identified 46 serotypes of Salmonella spp. Serogroup D was the most common (39.5z), followed by B (32.4z), C (22.7z), E (2.7z), A (2.3z), and G (0.4z). The three most common Salmonella serotypes were Enteritidis (36.3z), Typhimurium (16.8z), and Infantis (7.8z). Six strains that belonged to serotype Paratyphi A and nine that belonged to serotype Paratyphi B were also detected. The 256 Salmonella strains had a 38.7z rate of resistance to ampicillin, 23.0z to chloramphenicol, 8.2z to cefotaxime, 8.6z to ceftriaxone, and 6.3z to trimethoprim-sulfamethoxazole. The antimicrobial resistance rates of Salmonella serogroups B and D were higher than those of the other serogroups. Seven isolates carried bla CTX-M : four CTX-M-15, two CTX-M-14, and one CTX-M-3.

“…The ACSSUT resistance type is defined as resistance to AMP, CHL, STR, SXT, and TCY. Multidrug resistance phenotypes were defined as resistance to one or more clinically important agents, including AMP, ciprofloxacin (CIP), and SXT, as well as thirdgeneration cephalosporins ceftriaxone (CRO), ceftazidime (CAZ), and cefepime (FEP) [15,16].…”

Introduction: Salmonella is an important infection in Liaoning Province. Serotype and resistance levels are poorly studied. Knowledge of cephalosporin-resistant genes is needed to provide information to support the clinical diagnosis and to guide therapy. Methodology: A total of 172 isolates were collected from January 2009 to March 2014. Resistance to cephalosporin, fluoroquinolones, and other conventional first-line antibiotics was detected using the disk diffusion and agar dilution methods. The relatedness of isolates with the same serotype was analyzed by pulsed-field gel electrophoresis (PFGE). Genes encoding extended-spectrum β-lactamase enzymes (blaCTX-M, blaTEM, blaSHV, and blaOXA) were identified by polymerase chain reaction (PCR) and sequencing in cephalosporin-resistant strains. Results: S. Enteritidis, 1,4,[5],12:i:-, and S .Typhimurium were the most common serotypes. The resistance rate of Salmonella to conventional first-line antibiotics sulfamethoxazole-trimethoprim, tetracycline, chloramphenicol, and ampicillin was 21%,33%,37%, and 55%,respectively. To fluoroquinolones (gatixacin, levofloxacin, and ciprofloxacin), the resistance rates were 7%,18%, and 23%, respectively, whereas for extended-spectrum cephalosporins(ceftazidime, cefepime, and ceftriaxone), there sistance rates were 4%,8%, and 9%. In total, 14blaCTX-M, 14 blaTEM-1, and 1blaOXA-1 were found in 15 Salmonella isolates resistant to cephalosporin. No blaSHVwas detected. The blaCTX-M-55 gene was the most frequently encountered gene. The blaCTX-M-65 gene from S. Enteritidis is described for first time in Salmonella from humans. Results of PFGE indicated strong similarity among Salmonella isolates in Liaoning Province. Conclusions: Extended-spectrum cephalosporins are the first choice for the treatment of infection with Salmonella, but blaCTX-M-encoded resistance, including blaCTX-M-65, is present.

“…It was also reported that ciprofloxacin resistance rate was 8.05% (147/1826) in China (38). Resistance to ampicillin, chloramphenicol, and nalidixic acid were 20%, 11%, and 2.7%, respectively, in the United States (39). Surveillance programmes should be tracked carefully because of the extensive use of antibiotics in livestock production (40,41).…”

Background: Salmonellosis is still being reported as the second most common food-borne infection of bacterial origin. The most common serotypes worldwide as salmonellosis agents are Salmonella enterica subsp. enterica serotype enteritidis (S. enteritidis) and S. enterica subsp. enterica serotype typhimurium (S. typhimurium). Objectives: In the current study, the researchers investigated food associated S. enteritidis outbreak in factory workers of Turkey. Methods: The same meatball preparation that was consumed by the patients for lunch and dinner was responsible for the food poisoning on July 2014, when 257 workers in the same factory sought medical care. Among 257 individuals with diarrhea, abdominal pain, headache, fever, and vomiting, 48 (19%) were hospitalized. Stool samples were plated on Salmonella-Shigella agar and Eosine Methylene Blue agar plates and incubated at 37°C. Colonies morphologically resembling Salmonellae were selected for further identification on the next day using API 20E. Results: During the outbreak, 10 out of 48 (21%) stool samples and 1 out of 25 (4%) blood culture from patients were positive. On serotyping, the isolates were identified as S. enteritidis (9,12; g,m;-) by the agglutination test. Pulsed field gel electrophoresis (PFGE) used for epidemiological analysis of the isolates showed a similar PFGE pattern. Pulsed field gel electrophoresis analysis was performed by XbaI enzymes. The antibiotic susceptibility tests of isolates were studied according to clinical and laboratory standards institute (CLSI) suggestions by using the disc diffusion method. All isolates were susceptible to ampicillin, nalidixic acid, ciprofloxacin, trimethoprim/sulfamethoxazole, tetracycline, kanamycin, chloramphenicol, gentamicin, ceftazidime, and cefotaxime.
