The purpose of this study was to characterize the antimicrobial resistance produced by mobile genetic elements and integron gene cassettes in Escherichia coli isolated from the feces of captive giant pandas. We performed a standard disk diffusion antimicrobial susceptibility test with 84 E. coli isolates and further evaluated the mobile genetic elements and integron gene cassettes. The antimicrobial susceptibility test demonstrated that 43.37% (36/84) of the isolates showed multiple drug resistances. The E. coli isolates mainly showed resistance to aztreonam (86.90%, 73/84) and amoxicillin/clavulanic acid (80.95%, 68/84). The most frequently observed resistance patterns were ampicillin/amoxicillin-clavulanic acid (13.10%, n=11), and doxycycline/amoxicillin-clavulanic acid (4.76%, n=4). Further analyses detected 11 mobile genetic elements, of which merA (54/84, 64.30%) had the highest frequency. All isolates were negative for intI3, traA, tnpU, traF, tnp513, tnsA, ISkpn7, ISpa7, ISkpn6, and ISCR1. We further analyzed antimicrobial resistance-related integrons among 30 E. coli isolates (the 27 intI1-positive isolates and the 3 intI2-positive isolates); six gene cassette profiles (dfrA17+aadA5, aadA2, dfrA12+aadA2, dfrA1+aadA1, dfrA1, and aadA1) were identified in the 27 intI1-positive isolates, but not in the three intI2-positive ones. Our study sheds light on the prevalence of multiple drug resistances and the diversity of mobile genetic elements in E. coli isolates, and highlights the necessity to monitor antibiotic resistance in more E. coli strains from captive giant pandas.
