“…A total of 75.1% of the isolates were recovered from the young and middle-aged population. This is different from what had been reported previously for Typhimurium infection in Spain and enteric fever in India, where most of the isolates (76% and 90.2%, respectively) were recovered from children [3,4]. Humans may be exposed to Salmonella through consumption of contaminated water and food [5].…”

Introduction: Typhoid fever is a common disease in Yunnan province; however, the resistant phenotype and epidemic characteristics of Salmonella in this area are still unclear. In this study, a 15-year surveillance of antimicrobial susceptibility of Salmonella is reported. Methodology: From January 1999 to December 2013, Salmonella isolates were recovered from patients in the First People's Hospital of Yunnan Province. Antimicrobial susceptibility was detected and data were analyzed using WHONET5.6. Results: A total of 845 Salmonella isolates were recovered between 1999 and 2013. The most frequently isolated Salmonella serovar was S. Paratyphi A (93%), and 75.1% (635/845) of the isolates were from the young and middle-aged population. The resistance rates of Salmonella spp. to ciprofloxacin, ampicillin, and ceftriaxone increased dramatically during the 15 years. Carbapenems retained the highest and most stable activity against isolates. The resistance rates of all Salmonella isolates to chloramphenicol and sulfamethoxazole were 0.4% (3/845) and 1.8% (15/845), respectively. Conclusions: As Salmonella isolates have been observed to be resistant to first-line antibiotics, antimicrobial agents should be used rationally and prescriptions should be based on case-by-case susceptibility testing.

“…Production of enzymes due to extended-spectrum cephalosporinases has been observed in S. Choleraesuis resistance, and most of the isolates in this study were found to display this property with cephalothin (Table 3) [51]. This is an indication that the isolates could be harboring cefotaximehydrolyzing β-lactamases (CTX-M types) or CMY-2 AmpC β-lactamase that could hydrolyze cephalosporins normally transferred through conjugative plasmids, transposons, or integrons [52,53]. This is supported by the fact that resistance to β-lactams in S. enterica is primarily caused by the production of acquired β-lactamases [54], with TEM-1, PSE-1, and OXA-1 having been described as the enzymes most frequently related to ampicillin and amoxicillin/clavulanate resistance.…”

Introduction: Salmonella enterica subspecies enterica serovar Choleraesuis is a host-adapted, facultative, intracellular pathogen that causes swine paratyphoid. Its antimicrobial resistance presents a challenge to feed manufacturing industries. However, stopping antibiotics in animal feed would have economic implications for the industry. Methodology: Conventional microbial methods for isolation and identification of S. Choleraesuis were employed. The isolates were subjected to screening against 17 antimicrobial agents and genotyping of resistance markers by PCR. The data were then analyzed and presented in percentages. Results: Phenotypically, 43 out of 95 isolates showed multidrug resistance. Among the 17 antibiotics tested, resistance was observed as follows: sulphonamides (45

“…Sin embargo, en los últimos años se está observando un cambio, con cifras superiores para el serotipo Typhimurium 5-8 . La importancia de esta modificación radica en el perfil de sensibilidad, pues el serotipo Typhimurium se relaciona con mayores tasas de resistencia y multirresistencia antibiótica 6,9 . La resistencia a ampicilina y amoxicilina-clavulánico en SNT se atribuye a ␤-lactamasas plasmídicas clásicas, entre las que TEM-1, PSE-1 y OXA-1 son las más frecuentes, aunque las 2 últimas parecen quedar más limitadas al serotipo Typhimurium 6,10,11 .…”
