Nontyphoidal Salmonella from Human Clinical Cases, Asymptomatic Children, and Raw Retail Meats in Yucatan, Mexico

Abstract

Our study found a high prevalence of Salmonella in retail meats and persons with enteric infection; many of these isolates were resistant to clinically important antimicrobials. A random selection of isolates from people and retail meat showed genetic relatedness, which suggests that, in Yucatan, considerable transfer of Salmonella occurs through the food chain.

Non-typhoidal Salmonella Gastroenteritis in Al Ain Hospital United Arab Emirates

“…A recent study from Seoul, Korea showed no resistance to Ciprofloxacin and Ceftriaxone [21]. In Yucatan, Mexico, none of the isolates was resistant to Ciprofloxacin, and only 0.8% resistant to Ceftriaxone [20]. In contrast, 5% of our Salmonella isolates were resistant to Ciprofloxacin and 2% were resistant to Ceftriaxone (only on Serogroup B).…”

“…In Kuwait, about 39% of the isolate were resistant to Ampicillin, 17% to Co-Trimaxazole, 13% to Chloramphenicol [12]. In Yucatan, Mexico, resistance for the treatment of Salmonellosis was observed for Chloramphenicol (21%), Co-Trimaxazole (19.3%) and Ampicillin (17.6%) [20]. While in Korea, all isolates were sensitive to Co-Trimaxazole [21].…”

“…Some people may be asymptomatic carriers of Salmonella spp. [34] This research is affected by some limitations: first, in an observational study the investigator has no control over the composition of the control groups, and cannot randomize the allocation of subjects.…”

Brote de Salmonella Enteritidis resistente a ácido nalidíxico en Popayán, Cauca, 2011

“…Estos hallazgos concuerdan con los reportes de vigilancia en salud pública en Colombia, que muestran que Salmonella Enteritidis se considera uno de los serotipos con mayor porcentaje de sensibilidad en el país, exhibiendo resistencia solo a algunos antibióticos, entre los cuales el ácido nalidíxico representa el 2,4 % (8), porcentaje que no se considera significativo al compararlo con los de otros países, en donde se han documentado porcentajes de resistencia de hasta 36 % en Marruecos, de 50 % en España, de 22 % en Corea y de 47 % en México (25)(26)(27)(28).…”

“…En varios países son comunes los reportes de aislamientos de Salmonella Enteritidis con resistencia al ácido nalidíxico (25)(26)(27)(28). También se ha demostrado que la reducción de la sensibilidad a la ciprofloxacina es cada vez más común en muchas partes del mundo, con rangos de CIM para ciprofloxacina entre 0,125 y 1 µg/ml en aislamientos de Salmonella enterica (13,30), lo que se considera sensible según los puntos de corte del CLSI para ciprofloxacina en aislamientos de Salmonella de origen intestinal (22).…”
