Evolution of drug resistance in Salmonella panama isolates in Chile

Abstract: In a search for Salmonella isolates in the environment in Chile in 1975, drug-susceptible strains of Salmonella panama were recovered for the first time from river water and vegetables in the vicinity of Santiago. Two to 3 years later, antibiotic-resistant S. panama began to appear in a variety of sources (meat, animals, vegetables, etc.), giving rise to a human epidemic that involved the entire nation. Of 139 clinical isolates studied, 7 were drug susceptible, 11 were resistant only to nitrofurans, and 3 were… Show more

“…4,6 Panama was also the major serovar in humans in Colombia and Chile. 9,10 This high prevalence is in contrast to that in other regions of the world, including mainland France (0.5% in 2011), 11 highlighting the specific epidemiology of these regions. In industrialized countries, NTS is transmitted predominantly through commercially produced food contaminated with animal feces.…”

“…DNA was extracted from each of the 279 E. coli isolates (January 2006) using a Magna Pure LC apparatus (Roche, Germany) according to the manufacturer's recommendations, quantified by OD assay at 260 nm and adjusted to 100 ÎŒg mL −1 . Escherichia coli K‐12 DH1 containing plasmids PSU 2056 (Arakawa et al , 1995), PVC 2554 (Cordano & Virgilio, 1996) or PSMB 731 (Martinez & De la Cruz, 1990), which respectively carry class 1, 2 and 3 integrons, were used as positive controls. Plasmid DNA was extracted from control isolates using the QIAprep Spin Miniprep kit (Qiagen SA, France), also according to the manufacturer's recommendations, quantified by OD assay and analysed by 1% agarose gel electrophoresis in TAE 0.5 × buffer (45 min × 100 V).…”

“…␀-Lactam antibiotics are widely used in the treatment of salmonellosis. Recently, alarming reports have pointed out the rapid development of resistance to these agents, involving Salmonella serovars such as Enteritidis (28,44), Typhimurium (28,41,43), Panama (6), and Typhi (13) in several countries. Clinical strains of Salmonella spp.…”
