“…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.

“…PT 21 has been detected in isolate from humans and poultry products between 1995 and 1997 (Nunes et al, 2003). Whereas PT1 is the most prevalent PT in Italy (Nastasi et al, 1997), Denmark (Baggesen et al, 1997), Finland (Lukinmaa et al, 2006), Spain (Soler et al, 2006), and Japan (Itagaki et al, 2004).…”

We analyzed 66 Salmonella Enteritidis isolates in 2002. Thirty isolates were obtained from human patients with diarrhea, and 36 were obtained from chickens. A total of ten phage types (PT) were identified in the human and chicken isolates. PT1 and PT21 were the predominant PTs in both the human (20% and 13%) and chicken (17% and 47%) isolates. Twelve pulsotypes were generated by PFGE and divided into two major groups. Most of the PFGE types were categorized into cluster group 1. Eighteen chicken isolates in cluster group 1 showed high-level genetic association (>95%) with 22 other human isolates. Additionally, six chicken isolates from cluster group 2 showed fairly high-level genetic association (>95%) with the other seven human isolates. The highest levels of genetic association in humans and chickens were seen with A5-PT21 (11 isolates), A2-PT1 (7 isolates), and B1-PT4 (6 isolates). The Pulsed-Field Gel Electrophoresis (PFGE) and phage typing provided conclusive evidence that human Salmonella infections are attributable to the consumption of contaminated chicken.

“…Others studies supposed that the widespread use of antimicrobials in veterinary medicine may contribute to increase the resistance of pathogens to humans. Furthermore, the diversification of phage types results is probably associated with bacteria acquiring phage restricting plasmids or temperate phages (9,12). The emergence of phage types associated to multidrug resistance is a potential public health risk due to the zoonotic nature of human salmonelosis.…”

The gastroenteritis incidence caused by Salmonella Hadar has increased over the last decades worldwide. The uncontrolled use of antimicrobials for treating human patients and veterinary field contributes to increase the multidrug resistance of this serovar. In the present investigation, a total of 179 S. Hadar isolates from different sources of foodchain in Brazil were phage typed and analyzed for their antimicrobial resistance profile. The main S. Hadar phage types isolated were PT 38, PT 39, PT 40, PT 11, PT 34, PT 1 and PT 22. Others phage types as PT 13, PT 19, PT 21, PT 23, PT 31, PT 33 and PT 37 were obtained in low percentages. A total of 35,7% S. Hadar strains were resistant to two or more antimicrobials drugs. Furthermore, no resistance to third generation cephalosporin or ciprofloxacin was identified in these strains. Those results appoint to S. Hadar phage types circulating among animals, food and humans, as well as the increasing of multidrug resistance. The surveillance and monitoring of S. Hadar strains based on phage typing and antimicrobial resistance profile are useful for detecting outbreaks, identifying sources of infection and implementing prevention and control measures of salmonellosis.
