cord-323856-yr3zfxz3	Le Devendec, Laetitia	Development of a pig infection model with colistin-resistant Escherichia coli	2018-10-13		.txt	text/plain	5592	295	58	Of note, resistance to colistin (CST) had been detected at relatively low levels for years in commensal isolates, but prevalence was sometimes high for pathogenic strains (Kempf et al., 2016) , and after a publication on the emerging mcr-1 gene in China (Liu et al., 2016) , it soon appeared that this gene was also present in many other countries, particularly in pig E. In addition, fecal samples collected on Days 2, 9 and 17 were inoculated, after thawing, onto the Chromagar Orientation ™ agar medium (i2a, Montpellier, France) supplemented with colistin (8 mg/L) and vancomycin (8 mg/L) (CAO-CV) as previously described (Mourand et al., 2018) to detect colistin-resistant rifampicin-susceptible E. Considering only isolates obtained without enrichment, for group G2, 52 out of 53 isolates shared the characteristics of inoculated strain 12-246 M, and one isolate obtained on Day 14, without enrichment, belonged to PGG A, had the ERIC and PFGE profiles and the antimicrobial susceptibility of 12-246 M, including resistance to colistin, although it was negative for the mcr-1 gene.	./cache/cord-323856-yr3zfxz3.txt	./txt/cord-323856-yr3zfxz3.txt
