*Chi square test; P-value was set to 0.05
R0 = Isolates are sensitive to all antimicrobials tested
Key: R1-R8 = Number of antimicrobial classes in which a given isolate was resistant
MDR = Multi-drug resistance; number of isolates resistant to three or more of antibacterial classes
XDR = Extensive drug resistance; number of isolates resistant to all classes of antibiotics except one class of antibiotic
PDR = Pan drug resistance; number of isolates resistant to all classes of antibiotics
% of MDR, XDR and PDR were calculated out of number of isolates belonging each bacteria
